Looking some advice on whether its worth the extra volume to have a separate internal chamber for a plate amp.
I have a Powersoft Litemod 4HC (with heatsink) on the way as well as an 18 Sound 12LW1400 and am going to build something along the lines of 6th order bandpass enclosure that 18 Sound have on their website: 12” BANDPASS SUBWOOFER. 2 channels to power the sub in BTL and 2 channels to power a set of full range coaxial speakers i have.
A separate internal chamber within the sub for the plate amp seems more secure, but to provide adequate cooling its going to add a significant volume to the enclosure. Or is it likely to be fine in the main chamber. Keen to hear peoples experiences and recommendations.

maybe there are exceptions, but in general Plate Amps are designed to effortlessly take internal air pressure and seal it, so no need for dedicated internal chambers, just "cut the hole and mount it", they can share the general volume inside the cabinet with speakers.
Where?
Care to describe and draw the air path you imagine?
In the separate chaner, holes as needed.
At leasin and ouBut as you said, no need in a normal build.t.

Another thing to consider is mounting the plate amplifier so that the heatsink is outside the enclosure.
* Would said holes connect enclosure insides and free air? [YES/NO] pick one.
* How/where would you mount said fan?
* what/where is the expected airflow?
A drawing would be great.
* What is a normal build?
Well, yes,that´s the normal way to mount them: heatsink and connectors on the outside, board/supply/components on the inside.
Commercial plate amps come already mounted on a PLATE
Complete with mounting holes around so it fits in a proper sized cutout, most even with some kind of gasket to seal air leaks and ready to connect, mount and use.
Now the Powersoft product is more of an OEM one, not directly hobbyist or end user friendly, maybe it´s "just that": a populated board and a heatsink (and nothing else) inside a cardboard box, leaving mounting "details" up to end user.
Very different kind of solution, specially for a DIYer.
I suspect/(fear that you´ll have to cut and drill a flat aluminum plate, where you´ll sandwich the board inside, heatsink outside, also using thermal paste between contact surfaces.

My new cell phone is to blame for the unclear post...
The correct version of my post is:
"(fan) In the separate chamber, holes as needed.

A plate amp inside a speaker is in any case a wrong installation, the correct photograph is above.

Yes.
Actually neither fully inside nor fully outside, they sit at a boundary.
Actually a pressure boundary, so I can´t imagine where would you place a PC Fan and what path would airflow follow, care to share a drawing?

Hi,
Why even put it into your sub enclosure? You can keep your plate amp separate in an enclosure so that it's outboard and then never worry about replacing it when something fails and you have a custom chamber/square cut out on your sub 10 years from now.
Very best,

Very best,
In a separate chamber, isolated from the cone movement, I would make vents on both sides of the air flow, and put a proper size fan, with supply volts to suit, on the exhaust side, so as to draw in cold air, and pull, rather than push the air.
Inside a working speaker, not a good idea to put a fan.
Best is of course put the amp in a separate box, or an external amp, if you are not using it as a portable unit at events.
