Features 30 mm (1.18") round, 5.7 mm deep driver delivers big, clear sound from a compact footprint. Great for tight HO and N installs that still need real volume. 8 Ω WOWSpeaker — works with TCS WOWSound and most other-brand DCC sound decoders. Works with any scale that has room to mount it. More Information Brand Train Control Systems (TCS) Item Number 1696 Type WOWSpeaker (DCC sound speaker) Size 30 mm (1.18") round, 5.7 mm deep Impedance 8 Ω Condition New FAQ What decoders does this work with?It's an 8 Ω speaker that works with TCS WOWSound decoders and virtually any other DCC sound decoder rated for an 8-ohm load. Do I need an enclosure or baffle?Yes. Speakers need a sealed enclosure or baffle (or a sealed cavity in the shell) to move air and produce full sound — mounting it in open air will sound thin. What scales can use it?Any scale with enough room to mount it. Smaller drivers suit N and HO; larger round and high-bass speakers shine in HO, O, and G.

With our new modular speaker baffle set you can easily assemble your tailormade speaker baffle suitable for two miniature speakers. Both – diameter and height – can be individually adapted to suit your needs. Considerable audio pressure and excellent sound fidelity can be generated by employing two speakers wired in parallel. The popular 11x15mm sugar cube speaker with 8 Ohm impedance is supplied with a sealed mounting plate. First select one of the three base frames subject to the type of speaker you want to assemble, namely a circular frame with 28mm diameter or a rectangular type with either 16x35mm or 20x40mm. After you have inserted the speakers into the base frame you may now determine the height of the speaker baffle. The minimum height is 6mm, which can be raised to 8mm, 9mm, 10mm, 11mm or 13mm by adding up to three intermediate frames. The set contains two 2mm high and one 3mm high intermediate frame. They can easily be fixed with some glue suitable for plastic materials. The higher the speaker baffle, the better the bass fidelity. It certainly pays off to utilize the entire space available.  8 Ohm 20mm; 23mm and 16x25mm baffles and 1 11 x 15mm Speaker WARNING: This product can expose you to a chemical, which is known to the State of California to cause Cancer and Reproductive Harm - For more information go to www.P65Warnings.ca.gov

The Digitrax SP26158BC is a 26.5 x 15.5 x 9mm 8 ohm speaker supplied in a sealed enclosure and terminated in a 2-pin plug. If your decoder or locomotive motherboard has a matching speaker socket, this is the no-solder option: unplug the old speaker, plug this one in, and the install is done. The sealed box does the acoustic work that a bare cone cannot. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 2-pin plug terminated - drops straight onto compatible Digitrax motherboards and decoders with a speaker socket. No soldering at the speaker end. Sealed enclosure included. Nothing to scratch-build; the box stops the rear wave cancelling the front wave, which is where volume and low end come from. 26.5 x 15.5 x 9mm footprint fits HO diesel hoods, steam tenders and O scale frames where a 28mm round speaker will not clear. 8 ohm, 1/2 watt - matches the speaker output on most DCC sound decoders. Same speaker and box as the Digitrax SP26158B; the only difference is the plug instead of bare wires. More Information Brand Digitrax Item Number SP26158BC Product Type DCC Sound Decoder Speaker with Enclosure Speaker Shape Rectangular box Dimensions 26.5 mm x 15.5 mm x 9 mm Impedance 8 Ohm Power 1/2 Watt Enclosure Included, sealed Connection 2-pin plug Recommended Scale HO, O, G Condition New FAQ What is the difference between the SP26158BC and the SP26158B?Only the connection. The BC ends in a 2-pin plug for decoders and motherboards with a speaker socket. The B has bare interface wires you solder to the decoder pads. Speaker, enclosure and specs are otherwise identical. Will the plug fit my decoder?It mates with the 2-pin speaker socket used on compatible Digitrax locomotive motherboards. If your decoder has solder pads rather than a socket, order the SP26158B with bare wires, or cut the plug off and solder the leads. Do I still need to build a baffle?No. The enclosure is included and already sealed. Mount it where the opening is not blocked by the frame or a weight and you are finished. Will it work with my sound decoder?Any DCC sound decoder rated for an 8 ohm speaker output. If your decoder manual specifies 32 ohms, use a 32 ohm speaker such as the Digitrax SP531832B instead.

The Digitrax SP531832B is the largest Digitrax box speaker in its 32 ohm version - a 53 x 18 x 14mm driver already mounted in a sealed enclosure, for sound decoders whose amplifier expects a 32 ohm load. Where you have room for it, in an HO long hood, a large tender, or an O or G scale frame, the cone area and box volume give you low end that compact speakers simply cannot produce. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 32 ohm impedance for decoders that specify a 32 ohm speaker. Matching the decoder spec is what keeps the sound clean and the amplifier safe. 53 x 18 x 14mm enclosure - the biggest of the Digitrax box speakers, with the internal volume to produce genuine bass. Sealed enclosure included. No scratch-building a baffle; the acoustic work is already done. 1/2 watt rating with interface wires pre-attached for soldering straight to the decoder speaker pads. Measure first: just over 2 in. long and more than half an inch deep. For tighter installs, step down to the 26.5 x 15.5 x 9mm box speakers.

Use this 32 ohm version only where the decoder calls for 32 ohms. If it calls for 8 ohms, order the Digitrax SP53188B - the identical speaker and box in 8 ohm. What happens if I fit the wrong impedance?Too high and the sound is quiet and thin. Too low and the decoder amplifier draws more current than it is rated for, which can overheat or damage it. Always match the decoder spec. Will it fit in an HO locomotive?In a diesel long hood or a good-sized steam tender, usually yes - allow about 2-1/8 in. length, 3/4 in. width and 9/16 in. depth. In a switcher or a boiler it will not. Measure before ordering. Do I still need to build a baffle?No. The enclosure is included and sealed. Just mount it where the opening is not blocked by the frame or a weight.

The Digitrax SP13138 is a 13mm round 8 ohm speaker for the tightest sound installs. At just over half an inch across it drops into N scale shells, tenders and small HO hoods where a 28mm speaker will never fit, and it ships with interface wires already attached so there is nothing to solder at the speaker end. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 13mm round footprint fits N scale bodies, tenders and cramped HO installs where larger speakers will not clear the frame. 8 ohm impedance matches the speaker output on most DCC sound decoders, including the Digitrax SDN144 and Series 7 families. Interface wires pre-attached - strip, tin and solder to the decoder pads, no work needed at the speaker. Baffle or enclosure strongly recommended. Mounted in a sealed box the same speaker gains noticeable volume and low end; run bare and it sounds thin. Works with any DCC sound decoder rated for an 8 ohm load, Digitrax or otherwise. More Information Brand Digitrax Item Number SP13138 Product Type DCC Sound Decoder Speaker Speaker Shape Round Diameter 13 mm Impedance 8 Ohm Connection Bare interface wires (no plug) Enclosure Not included - baffle recommended Recommended Scale N, HO Condition New FAQ Will this speaker work with my sound decoder?Yes, as long as the decoder drives an 8 ohm load. Check your decoder manual for the rated speaker impedance - a decoder that specifies 32 ohms needs a 32 ohm speaker instead, such as the Digitrax SP282832. Do I really need a baffle or enclosure?It makes a large difference. A bare speaker cone lets front and back waves cancel each other, which kills the bass. A sealed box - even one you fold from sheet styrene - will noticeably improve volume and tone. Can I wire two of these to one decoder?Two 8 ohm speakers in series give 16 ohms, which is safe for most decoders. Wiring them in parallel drops the load to 4 ohms and can damage the decoder, so check the manual before doubling up. Does it come with a plug?No. The SP13138 has bare interface wires. If you want a speaker that plugs straight into a compatible motherboard, look at the Digitrax SP26158BC with its 2-pin plug.

The TCS 1718 is a tough little 17mm x 12mm "Micro WOW" sugar-cube speaker hand-picked by Train Control Systems to fit in tight spaces — originally selected for the Bachmann N-scale Siemens Charger — but at just 2.25mm tall it slips into all sorts of HO, N, and other small-locomotive sound projects. It ships pre-wired with 4 inches (100mm) of twisted-pair 32AWG leads, so you can drop it in without crimping anything. Looking for more DCC sound parts and decoder accessories? Browse our Track Tools & Accessories collection. Features Compact 17mm x 12mm x 2.25mm footprint — small enough to fit in the boiler, fuel tank, or shell of an N-scale or HO-scale locomotive where most speakers won't go. 1.0W nominal / 1.5W peak power handling at 8 Ohms — pairs perfectly with TCS WOWSound and most modern DCC sound decoders. 95 dB ± 3 dB SPL with an effective frequency band from 870 Hz to 20 kHz — clear, accurate sound across the whole locomotive audio range. Pre-installed 4-inch (100mm) twisted-pair 32AWG leads — ready to wire to your decoder without any soldering of speaker tabs. Multi-scale — designed by TCS for the Bachmann N Siemens Charger and works in any locomotive shell with room for a 17 x 12mm speaker. Scale: Multi-scale (commonly used in N and HO). Important Safety Note TCS WOWSound decoders use an audio amplifier capable of supplying up to 2 Watts of power to an 8 Ohm load at maximum volume. Set your master volume to roughly 50% or less to prevent over-driving and damaging the decoder or speaker. The same rule applies to any DCC sound decoder rated above the speaker's 1W nominal continuous power.

TCS selected this speaker specifically because it fits the Bachmann N-scale Siemens Charger, but it's small enough for many other locomotives. Measure the space first — the wires add a little overall length. What decoders does it work with?Any 8-ohm-compatible DCC sound decoder — TCS WOWSound, ESU LokSound, SoundTraxx Tsunami2/Econami, Digitrax SoundFX. The 8 Ohm impedance is the universal standard. Do I need to solder anything?Not to the speaker — the twisted-pair leads are already factory-installed. You only need to connect the two wires to your decoder's speaker pads. Should I add a baffle or enclosure?For best bass response, yes — even a small sealed cardboard or 3D-printed enclosure makes a noticeable difference. But it'll still sound great without one.

The Digitrax SP28288 is a 28mm round 8 ohm speaker, the classic full-size cone for HO and larger sound installs. The bigger diaphragm moves more air than the small oval and 13mm speakers, so prime movers and whistles come through with real body - mount it in a sealed baffle and a single 28mm speaker will fill a room. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 28mm round cone gives noticeably more volume and low end than 13mm or oval speakers, the usual choice for HO diesel hoods, boilers and tenders. 8 ohm impedance matches the speaker output on most DCC sound decoders, Digitrax and otherwise. Interface wires pre-attached - nothing to solder at the speaker, just tin and connect to the decoder pads. Baffle or enclosure strongly recommended. A 28mm cone run bare cancels its own bass; in a sealed box the difference is dramatic. Check clearance before ordering - 28mm needs about 1-1/8 in. of width, which rules out most N scale shells. More Information Brand Digitrax Item Number SP28288 Product Type DCC Sound Decoder Speaker Speaker Shape Round Diameter 28 mm Impedance 8 Ohm Connection Bare interface wires (no plug) Enclosure Not included - baffle recommended Recommended Scale HO, O, G Condition New FAQ Which impedance do I need, 8 ohm or 32 ohm?Match the speaker to what your decoder manual specifies. Most DCC sound decoders drive 8 ohms. If yours calls for 32 ohms, use the Digitrax SP282832 - the same 28mm speaker in a 32 ohm version. Will a 28mm speaker fit my locomotive?It needs roughly 1-1/8 in. of clear width plus depth for a baffle. That is comfortable in most HO diesels, larger steam tenders, and anything O or G. For N scale or a tight HO steam boiler, use the 13mm SP13138 or the oval SP10188 instead. Do I really need an enclosure?Yes, if you want it to sound like a locomotive rather than a transistor radio. Sealing the back of the cone stops the rear wave cancelling the front wave, which is where all the bass comes from. Can I run two speakers off one decoder?Two 8 ohm speakers in series make 16 ohms and are safe on most decoders. In parallel they make 4 ohms, which can overheat the decoder amplifier - check your decoder manual first.

The Digitrax SP282832 is a 28mm round speaker in the 32 ohm version, for sound decoders whose amplifier expects a 32 ohm load. It is the same full-size cone as the 8 ohm SP28288 - the extra diaphragm area gives HO and larger locomotives real low-end punch - and it ships with interface wires already attached. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 32 ohm impedance for decoders that specify a 32 ohm speaker. Fitting an 8 ohm speaker to a 32 ohm output is the most common cause of distorted or quiet sound. 28mm round cone moves far more air than 13mm or oval speakers - the usual pick for HO diesel hoods, boilers and tenders. Interface wires pre-attached - nothing to solder at the speaker end. Baffle or enclosure strongly recommended. A sealed box is the difference between thin and convincing. Needs roughly 1-1/8 in. of clear width plus depth for the baffle, so check the shell before ordering.

Use this 32 ohm speaker only where the decoder calls for 32 ohms. If it calls for 8 ohms, use the Digitrax SP28288 instead - same speaker, 8 ohm version. What happens if I use the wrong impedance?Too high an impedance gives quiet, thin sound. Too low draws more current than the decoder amplifier is rated for and can overheat or damage it. Matching the decoder spec is always the safe route. Will a 28mm speaker fit my locomotive?It needs about 1-1/8 in. of clear width plus room for a baffle - fine in most HO diesels, large steam tenders, and anything O or G. For N scale or a tight boiler, use the 13mm SP13138 or oval SP10188. Do I need an enclosure?Strongly recommended. Without one the rear wave cancels the front wave and you lose the bass entirely. Even a simple sealed styrene box makes a clear difference.

The Digitrax SP10188 is a 10 x 18mm oval 8 ohm speaker - the shape that solves N scale sound installs. An oval fits the long, narrow space along the top of an N scale shell or inside a tender where a round speaker of the same area simply will not go, and it ships with interface wires already attached. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features 10 x 18mm oval footprint fits the long narrow cavities in N scale shells and small HO boilers where a round cone will not. 8 ohm impedance matches the speaker output on most DCC sound decoders. Interface wires pre-attached - nothing to solder at the speaker end. Baffle or enclosure strongly recommended. Small speakers gain the most from a sealed box; run bare, an oval this size sounds thin. Works with any DCC sound decoder rated for an 8 ohm load, Digitrax or otherwise. More Information Brand Digitrax Item Number SP10188 Product Type DCC Sound Decoder Speaker Speaker Shape Oval Dimensions 10 mm x 18 mm Impedance 8 Ohm Connection Bare interface wires (no plug) Enclosure Not included - baffle recommended Recommended Scale N, HO Condition New FAQ Why choose an oval speaker over a round one?Shape. N scale shells and small steam boilers give you a long narrow cavity, not a circle. An oval uses that space, so you get more cone area than a round speaker that has to fit the narrow dimension. Will it work with my sound decoder?Any DCC sound decoder rated for an 8 ohm speaker output. Check the decoder manual - if it specifies 32 ohms, you need a 32 ohm speaker instead. Do I need a baffle?It makes a large difference at this size. Sealing the back of the cone is what produces the bass; without it the front and rear waves cancel and the sound goes thin and tinny. Is there a bigger option for HO?Yes. If the shell has room, a 28mm round or one of the rectangular box speakers with an enclosure will give you noticeably more volume and low end.
