Active Crossover Conundrum!


I am thinking very seriously about using an active crossover with my Klipsch Cornwall lV’s. I have 3 amplifiers, a First Watt SIT-3, Pass XA-25, and the most recent purchase, a Modified Bottlehead 2A3 amplifier. I am considering a Marchand or a DIY Nelson Pass designed active crossover.  Some of the questions I have rattling around in my noggin are; Can I get away with a 2 way? What amplifiers would be best at what driver? Would a 45 or a 300b be a good addition? Should I have my existing passive crossover modified instead? Are there many enthusiasts that have tried active and returned to passive crossovers?

I have already biamped my XA-25 and my SIT-3 and have enjoyed that combination.

The rest of my equipment is as follows: Cary SLP-98, Lumin U1 mini and a BorderPatrol DAC.

Any suggestions from those who have tried or are presently using an active crossover is appreciated.

 

Thanks!

 

ps, I have been listening to the 2a3 since Friday night and it is really really good… amazing results from just 3.5 watts!

@ditusa - thanks for the article. My idea is using the SIT-3 from 0-500, a 45 amp from 500 to 7000 and my heavily modified Bottlehead 2a3 from 7000+.

Sounds like a good idea. That said, bi-amping or tri-amping speakers should not be undertaken without first asking the manufacturer’s advice.

When I horizontally bi-amped my speakers with an analog active crossover design by the same manufacturer (of the speakers) it brought my speakers two notches above the passive crossover in sound quality. 😎
