DAYTONAUDIO TCP115-4 4" Treated Paper Cone Woofer

The Dayton TCP115-4 4” woofer meets its specifications on the Dayton website. It is exactly what I hoped it would be, with a good clean sound and smooth frequency response in a correctly ported bass-reflex cabinet. I needed a free air resonance (Fs) a bit less than 55Hz to go in a small bass reflex cabinet measured with a Helmholtz resonance of 38Hz (a combination to fit the optimum ratio of 1:0.71). Each of the pair of Dayton woofers I bought has Fs of 53.8Hz, verified with audio test gear. They are a perfect fit mechanically, acoustically and electrically to supplant the existing unsatisfactory units. It is almost as if the cabinets I’m fitting these to were designed with this particular Dayton in mind, and merely had the wrong drivers (85Hz Fs) fitted at the factory. Now instead of the horrible boom at about 80-90Hz and nothing much below, the response is smooth from about 40Hz and almost flat past 3KHz before needing help from the tweeter. The TCP115-4 4” code explained TCP is this particular series of woofer drivers 115 is the overall nominal frame diameter (actually 116.5mm) -4 is the nominal impedance of 4 Ohms (actually 3.2 Ohms in series with 0.97 mH) 4” is the nominal diameter of the cone area. Useful notes. Cone excursion can be up to 4mm p-p; allow 10mm clearance from mounting surface! The mounting hole needs to be 93mm diameter The mounting gasket is loose with four notches matching four mounting holes. The four 4.4mm diameter mounting holes are on a 108mm diameter circle. The speaker is 65mm deep overall The back of the magnet is 58mm behind the external mounting surface. The assembly of magnet and pole pieces is 80mm in diameter and 25mm deep. The symmetrical pole pieces are designed for lowest distortion in a vented cabinet.

Built for a stereo Bluetooth speaker I made . I added a subwoofer crossover. And bought 2 tweeters. With 2 other mid drivers. Add a Bluetooth amp and boom box pleasures to be had. And a good price. Looks the part.

I'm honestly very impressed with this little sub genuinely a great little speaker and I'm very happy with it.

These drivers go for peanuts in the US, but Dayton Audio is a respectable brand. Honestly these woofers are rather understated, 4mm of xmax is impressive for a 4" driver and these woofers are forgiving in enclosure type, so are a good drop in for a damaged PC speaker sub-woofer or portable speaker projects where you don't want to give up the low end. I put this in a compact sealed enclosure with about 1.7L of internal volume, and these drivers put out a wonderfully warm and confident bass even touching 35Hz by a hair, with extension down to 45Hz solid when driven by a fair amount of power. So I can see these performing wonderfully in a compact 2-way system such as a bookshelf speaker or small bluetooth speaker project.

Cute little sub for a homemade speaker system. Running off usb power with crossover and car speaker on the high end. I'm sure I can get more out of it when I upgrade the preamp

All good, made a small speaker cab to use with a 5watt micro amp, worked well, pleased

Bought these to replace my blown subs in my Yamaha soundbar. Sound even better than the originals. Great buy.Great price !

Great little speaker with fantastic bass sounds for ots size, highly recommended.

11.5cmのコンパクトサイズながら元気に中域〜低域を再生してくれます。ダブルインストールのサブウーファーをステレオ出力で鳴らすことで音質と音圧の両立を目指しました。デッキ内蔵アンプ(50w×4)2chで十分駆動できます。パッシブクロスオーバーを使えばフロント2way＋サブの構成を外部アンプ無しに構築できます。

Los instale para jugar video juegos y compré aparte un amplificador son geniales

This little guy as is with no enclosure just to see what it does is impressive. Definitely can be paired with a good tweeter in a 2-way configuration since the tones in the mid and treble region is very smooth and undistorted unless pushed a little too hard. Plenty of excursion for an upcoming Bluetooth Ammo Can speaker project I've been working on for a while, may as well use this, a fitting tweeter, ported and tuned to around 43 Hz. I'll probably end up getting more of these little 4" woofers in the future because I have never seen a driver of this size move this much!

Also für das Geld,...klare Kaufempfehlung ‼️🤤 Wer alte Lautsprecher gegen diese austauscht wird sein wahres Wunder erleben‼️

Este altavoz es muy potente, aunque no es un verdadero Subwoofer lo he utilizado como si lo fuera ya que su rango de frecuencia empieza en 55Hz, mucho más bajo que los que traen los altavoces portátiles que suele ser 75Hz. Tiene pegada y en mi caso lo he puesto con radiadores pasivos en lugar de puerto de graves y también le puse algodón acústico y suena como si fuera mucho más grande. Tiene 40W rms y máximo 80W rms. Eso si, tienes que ponerle un amplificador que esté en ese rango de potencia porque si le pones uno inferior va a distorsionar con volumen alto.
