Hi. I have read a number of threads here and found some useful information (noob here).
I want to find out more about bi-amplification. I have read some threads here on the subject, but I would like to be sure of something. I have designed and built many amplifiers, my latest being an amplifier intended for use as a bridged amplifier. I have an 18-0-18 transformer with enough VA for a bridged design to provide 100W stereo into 8 ohms.
But I have been thinking that I should rather use the amplifiers to bi-amp my speakers (Celestion F20). I definitely want to put in an active crossover (it's a very minor modification on the board), and it will only be 1st order. I want to do this to benefit from the separation of high and low spectra to compress my power a bit, and get more headroom.
What's baking my noodle is that I want to leave the passive crossovers in, but I don't want them to interfere with the potential quality of the signal reaching the drivers. The preamplifier filters are a LPF at 2700Hz and an HPF at 2400Hz, and the speakers have a crossover frequency of 2500Hz. I want to leave the passive crossovers in because each amplifier is identical, so I need the speakers to attenuate for the highs.
I know this will work, but is there truly a measurable benefit to taking the passive crossovers out?
This is a DIY project which I'm keen to make a post about (the amplifier, that is).
