[QUOTE="Eva Paz, post: 31703, member: 795"] Re: SpeakerPower Torpedo SP1-4000 Plate Amp (3 of 3) Hi all, I'm new to this forum. I wonder why the impulse response plot taken from the SP1-4000 is 20ms longer than the input signal, has different attack envelope and contains 11 cycles instead of 10. I've tried to get the same result and for the moment the only way I found is by adding a 80Hz 24db/oct low-pass filter to the signal (the group delay results in an extra cycle). Otherwise, the impulse response looks much like the input signal and matches PL380 performance. [/QUOTE]
