Active Crossovers

[morricab]

I have the Dayton DSP 408. Its super fast and easy to dial in the slope, gain, phase, crossover point. Even has a full EQ. Can cut top and bottom on a 3 way. Its a nice tool. All I am saying is why buy another tool. I have one. If I proceed, I will eventually go active analog. Like a Merchand tube. Even those need to be modified. OCD Mike has a video on how his is built. No op amps.

I will try the Blade and the 845. I don't think its going to work. Whats that Amp Ralph talks about. Dynaco ST70. I still think about a CJ Classic 62 SE for the woofers. Maybe a good 300B for the top and the Blade on the woofers. But the Blade has always been more detailed than rich. I am looking for a richer amp on those woofers. I think. Still learning where the music is most important. I am very surprised how important 600 hertz and down is for vocal and really the whole of the music.

Ah, ok. I thought the Dayton was just for subs. I see now it’s basically like a mini-DSP .

I would try all tubes. If you want a richer sounding PP tube amp try a Prima Luna or a Willsenton EL34 amp( a friend bought one and it is rich but still reasonably transparent).

A Marchand tube cover is IMO the way to go with analog xovers. The Accuphase is ok, but is holding back the system.

What Prima Luna. Seems to be affordable ones of the 100 series, They go up to monoblocks and 300 series.

Or a Phil Marchand fixed crossover?

I tried the 845 as the main amp with the Elrog tubes. The Blade on the woofers. The 845 is too fuzzy and loss of detail. Not a good match. I am not anxious to try the other way as a SET is not the amp to put on woofers. I guess I could use the DSP and set the high pass as 60 hertz and let the sub do the rest.
