Default Plateamp finally installed in my XLS 12" sub

Finally got around to installing my Class D amp plate amp in my trusty XLS 12 inch vented sub.
Amp running +-60Vdc so power around 300 W into 6 ohm (which is more or less what the driver represents though it is called 8 ohm ... Rdc = 4.7 ohm).

It is based on my own implementation of IRS2092 with both pre and post filter feedback, and a buffer input stage. Fets are IRFB5620.
Protection; Over voltage, under voltage, current, DC.

Box tuned to ca 23 Hz, and works really well, no preamp implemented, as I'll be making the ajustments from the surround amp.
The amp is actually placed in the vent, as it is a flat serpentine implementation

At +-60Vdc and 275 kHz, the output coil based on T106-2 gets to around 45-50 deg.
The whte fluff is for the cables not to rattle.

Also a pic of the actual modules.

Special thanks to Joe Bocani for making these amps available to DIYer.

Hi Eric, can you share by any chance how the DIY community can find those ICEPower modules available for purchase?

Hope this helps,

As always - the last built gizmo is the very best

Yea something is up with this. You dont get crossover distortion with a class D amp, as its class D, there is no inbetween, either the top mosfet is on, or the bottom one is, and any artefacts in the waveform are the result of the varying time periods of the PWM waveform.

I would do a trace on the signal leading up to the TPA and see what you get.

Just wanted to post a picture of two D-amps with inexpensive SMPS in test configuration.
Both work fine and reliable in this combination. I tested them under load, driving 4 woofers for more than 36 hours at 10V p-p. Nothing gets hot, all temperatures under 45C measured with an IR termometer.
These amps and SMPS are the cheapest you can find at AliExpress and pay with PayPal.

This is NO final installation! They seem to interferr with FM radio somehow, so please use a metall inclosure.

TDA3116 2x50w
TDA7498e 2x100w
Smps 24v 120w
Smps 32v 180w

Here's my build of an SMPS400 and 2x UCD180 with HxR buffers. Enclosure front and rear panels were CNC'd by me. The Aluminium profile is standard 2060 which is available from aliexpress, eBay etc.

You can see some more details here: Enclosure for Hypex amps: 2060 alu profile and CNC work
