    My Lepai measures 4.5" x 5" x 1" and fits on the narrow back side (non port side) of the Voxel. Perfect size, but crappy sub amp.

    That new Dayton looks like a *much* better sub amp but measures 8-1/16" H x 7-1/16" W x 2-1/8" D. It'd fit on the side opposite the woofer. I'd probably build it out a touch to account for the slightly extra internal room (if using 1/2" plywood).

    This newer Dayton plate amp is 100 watts for 100 dollars as opposed to the 70 watt for 72 bucks...



    It has no plastic back so it shouldn't take any extra space in a 3/4" box.

    There are also small class D deaktop options for $80 or so that won't even need an enclosure mount. Check out Amazon for some of those. I've been using a Nobsound G2 Pro 300 watt sub amp for several months and it's great.

    If someone made a plate amp that was small enough and had certain features (like a quality adjustable crossover, non thump when powering off, etc.) this little sub would then go from outstanding to absolutely freaking fantastic.

    The one I built I used the Lepai LP210pa, but I personally wouldn't recommend it (the amp). In the right situation I can get it sounding good, but otherwise it's just not a very good unit (that plate amp also rattles and is near impossible to knock that completely down). It does, however, sound good with my Tivoli Model Two setup (as it has a sub out) when positioned correctly and that's where I primarily use it now.

    For fun, I've also hooked it to my 80's Panasonic "boom box" via the RCA line out ports. It's a line level out so the volume adjustment must be made at the plate amp, but otherwise I've fooled a friend or two into thinking the Panasonic can dig down to 40Hz.

The Dayton SA70 plate amp extends so far into the sub box that it’ll decrease the total internal volume. Has this been taken into account? Or should the box be increased in size to accommodate the plate amplifier?
    It should be increased to accommodate the plate amp.

    yes, cherry, peel and stick.
    I got it from a different source and the adhesive was a clear stretchy material rather than what I usually see for 3M. It was more of a pain to work with as the router blade would grab the adhesive and pull it off the edges of the veneer. I ended up pre-slicing the adhesive around the edges with a blade and that helped but it still doesn't grip anything like the other 3M stuff.
    Woodworking can be so frustrating and yet fulfilling at the same time. All the practice it takes to get better leads to a lot of projects that are 'almost' good enough up close. I've gotten better at convincing myself that nobody will ever be up that close so they aren't going to notice anyways.

    I made a voxel years ago and used a tpa3116 2.1 amp and it popped like you said with your amp but i came across this amp board recently. It has 75 watt RMS at 4ohm for the subwoofer and 2 stereo channels. It have wifi and bluetooth and even dsp. The power supply is only 19V so not recommended but the remote is pretty cool. Just an idee but really cool amp boards at first look at it! BTW do you have port chuffing and wich diameter port do you use?

    thanks!

    I use the Dayton SA100, I had it from using with a dayton 8" sub so it is probably overkill here as I don't think this would like that much power but I keep the gain fairly low. My listening levels are usually pretty low.

    I'd love to find an amp for it that wouldn't thump when the power gets disconnected and reconnected. Not only could I make it switch off completely with the amp but when our power blinks it is an interesting sound in the middle of the night.

    I'm planning to build one more of these.

    Nice job, looks really expensive. How much watt do you give it?

    thanks! I still can't get over how much these add to the music. The big plus is they blend so nicely with the main speakers that I don't even notice what the Voxels is adding until I turn it off.
