Interesting, does this mean that if you got a speaker and played some loud music then put a stupidly powerful fan inbetween you and the speaker, the soundwaves would get 'blown' out the way and you wouldnt hear anything?
I think it's possible that a fan may affect the sound somehow, but it may only happen if you have a big fan or with certain frequencies... I guess to be sure I need to measure the speakers performance before and after installing the fan...
as the speaker works harder, so too wouldnt the amp? And as the speaker is moving more air, it would provide some level of cooling for the amp, no? (Might be assuming its a ported enlcosure here, but then if it isnt, i dont know what good a fan will do?)
Yep it's ported, nothing fancy. I have yet to see how hot the amp is getting, it may be fine, but if it was getting too hot, then I was thinking about what I could to stop overheating.
high frequencies stuff will get reflected, sure.
Mick couldnt you mount the modules to the outside of the box, heatink pertuding out? it shouldnt be a problem then, just strap the fans to the heatsinks?
I'm not really worried about frequencies over 2.5k, the tweeter is sealed.
I want to keep this amp in the box if I can, the speaker was originally active before the LM3886 overheated and went bang.
The speaker is an Event TR8, and the manufacturer skimped on the heatsink and trafo, but I'm assuming they made the speaker so that the volume of the air inside includes the amp, plus it already has mains connectors in which I plan on using.
I may be able to use an Alu plate as an access panel, and have this as a heatsink also... As I said, I don't even know how hot it will get yet, it's Class-T/D so could be fine.
