One of my first projects was an under-bed sub. It has always suffered an unseemly rattle from the port at high output. I have since moved on but the source of this noise still bugs me. It's a 6.5" driver in an 8 litre cabinet with a 40mm x 125mm side-facing port. I've changed the port. I've changed the driver - still the rattle. By process of elimination I've concluded that it can only be a fault with the plate amp.
Unless in my efforts to be 'efficient' and 'smart' I placed the vent opposite the plate amp's heat sink to aid cooling.
Could that be it?
