Dayton Audio PC105-4 4" Full-Range Poly Cone Driver

Dayton Audio PC1054-4, 4" full range speaker -- big magnet, strong construction. Buying a 2 to 4 Watt practice guitar amp costs around $30 to $90 and will probably have 2" speakers. This build probably cost around the $90 range with the power supply I made. I put the speaker in a "Filthy Chooligan" cigar box I got at a local cigar shop. It just fit between the ribs. I wanted to preserve the label side of the box. I 3D printed a cover for the speaker and the box for the power supply. I used a TDA8932 mono digital amplifier board, also bought on Amazon. Something like $9 for two boards. With a Dremel tool, mounted the jack and power jack, as the wood has to be reduced to mount the jacks. I didn't put a power supply or batteries inside but two 9V USB rechargeable batteries in series would power it well enough and mount a USB-C charge jack on the outside -- cable on Amazon. It plugs into these batteries to charge them. Need a USB-C Y adapter to charge two batteries at once. I made a linear power supply - the other orange box on the right. The sound is clear and bright.

It was a perfect fit for the application, but wrong imjpedence. I returned this item, and purchased the 8-ohm version.

Good product ....!!!?

These are very nice sounding speakers with surprising high range and easy to install with my Bluetooth amplifier

When I ordered this Dayton Audio PC105-4 4" Full-Range Poly Cone Driver, I tried to cancel the order about 20 minutes later. It turned out that the speaker I mistakenly believed to be faulty was fine (it was a poor connection) and did not need to be replaced. Twenty minutes was too late, and the order could not be cancelled. It arrived about 14 hours later. I began processing a return of the product before the package had been opened. However, I was intrigued by the weight of the package. My curiosity got the best of me, so I opened it and was favorably impressed! I decided to remove the OEM speaker from its Logitech Z313 Speaker System Subwoofer enclosure. When the speakers were next to each other, the mass of the Dayton Audio PC105-4 was about twice that of the original. The quality of the materials & manufacturing is superior with Dayton Audio's product. After soldering the wiring to the new speaker and mounting it into the enclosure (with no modifications), I reconnected the rest of the wiring and the power. The real test was while it was in use. I was surprised in a good way! Typically, I do not listen to audio at high dB/SPLs (nor do I recommend it), but did so to gauge the efficiency of its power handling and output. It was amazing when I noticed that a sheet of paper sitting about a foot away began vibrating from the sonic shockwave... The dirt-cheap price and great quality are enough on their own to make this an awesome buy. Quick delivery, and the fact that I changed my mind to keep a product that I have no need of when I could have returned it for free, can only mean that gets two BIG thumbs up!

Didn't sound as good as my old speakers.

Nice full range speaker. The bass is deeper than I imagined it could be. Clear and crisp sound also. I replaced the speakers in my Spark amp with these.

Very solid little full range. I used it to replace a damaged cone in a small Fostek 6301B and it sounds as good as the original driver. It's a very tight fit in the monitor enclosure but this speaker is pretty much exactly the same as the Fostek cone so it worked out great.
