Active Crossovers

[morricab]

The Audion Dream 845/52b is a tube amplifier that was one of the cleanest and best modern ones. I had the highest-end model Erik Andersson ever made, only a few of them, all silver transformers. It had one drawback: a very sensitive input, and the amplifier favored passive preamps.

The XTA is a sufficient DSP for a home system. I've tested it with Tad, JBL, Yamaha Altec, etc.

The best effect I've heard at home with a DSP is Dolby Lake! It's a wonderful machine, but difficult to set up.

I've used over 10 different crossovers in various systems, from the pricey Westlake with their HR1VF, to a simple Rane with Strathearn studio monitors, 6 ribbons, and 18 bass drivers with 0.5 ohm impedance.
So, it depends on the application, and a simple Rane is enough.

His has been messed with significantly and I suspect something went wrong with the mods…

It was the original amplifier, maybe my speakers were too efficient for them
But the sound was different than what we think of SE. I also had Wavac, Audio Note, and Vaic SE for comparison.

Why isn't this trying to build a partially active system? a tube amp in front of the tweeter horn and 10" Beyma coax driver (please remove the horn funnel). You use the passive crossover 12 dB for horn driver for the 10" Beyma without xover. Then you measure the frequency response of how far the combination plays from the lower limit frequency. then you buy active bass xover then an amp that controls everything 2x 15" + your subwoofer and adapts it to the rest.
I am running such a solution sounds excellent
P.S
Maybe you have to adjust a resistor in front of the horn driver to get flat response
I hold every bet that 10" works down 100-150 hz in your baffle( blue line)
