Currently running a pair of 2226s in 4 cu ft enclosures tuned to 45 Hz, 2445s mated to 250 Hz Tractrix horns and 2405s with an active/passive setup. Running a MiniDSP, which lets me bi-amp the 2226 and 2445s. X-over is 500Hz 24/12.
2405s are passive 12 dB/octave at 8 kHz.
I've not really been happy with the handoff between the 2445s in the big horns and the 2405s.
I've been considering tri-amping the whole thing and running the dayton AMT ribbons. The thought would be to run the 2445s from 500 Hz - 3500 Hz and have the AMTs take over after that.
Either get a MiniDSP 4x10 HD or something similar to do the x-over. Also run a 47 uF on the 2445 and a 20 uF on the AMT for protection.
Anyone have thoughts on this? Would the AMT be able to keep up with the 2445? (Home listening levels).
I've also recently changed from powering the 2445s with a pair of 300B amps to a 6-channel SS amp.
