Thanks CharlieLaub,
Post 40 made things a lot clearer for me - I knew the resonances were acoustic problems but assumed your statement meant that even when fed with notch filtered pink noise the big peaks would still show up on the RTA. Would I be right in thinking they will only show up when the driver is distorting badly or the ports are being well overdriven ?
I've got to admit I've never seen any reference before to the actual ports generating tones to excite their own resonances - only spider noise, wind noise in vented magnets and harmonic distortion from the driver itself.
Every days a school day 😀
Cheers,
Rob.
