SPL - Pro Audio Blasphemy?

A few years back I acquired a pair of Legacy Focus speakers, HUGE! At 200 lbs each and 5 feet tall, they are awesome to behold. But, I found them hard to drive. The specs say you should be able to drive them with any 200wpc amp. And you can, but, I found it lacking, not reaching their potential. So, I took my hi-fi amp. A Forte' 200wpc, and I drive the top half with that, and I bought a used Crown XLS2500, which is about 475wpc, to drive the bottoms. And am very pleased with the results! Now it has slam! But still remains so smooth on top even at higher volumes. I only paid $400 for the used Crown in like new condition, and it saved me from spending $5,000 on a Krell or Levenson monster amp. I may still get a Krell or Levenson monster one day, but for now I'm very happy with this Pro audio amp in my system.

Very cool insights.I think having an entire rig of pro gear for home listening is not the way to go, but some areas could be helpful. As stated before, if you are going passive that would be the obvious area to acquire pro gear for. I remember linkwitz for his speakers uses very ordinary pro amps and PMC has bryston in them. I feel that some speakers, like for instance Harbeth, feel that amplification is cheap and abundant and it is there to amplify, nothing more.

Also, I think the 120v rails is confusing, because I think it is different running of 120v AC. Look at the Innerfidelity video on the Phonitor 2 at Newport, and the rep explains it. To paraphrase he says that most gear runs on 36v rails and that 120v rails gives you more head room and dynamic range. Sounds interesting.

Would the wide use of balanced connections and power conditioners be two areas where the pro side influenced the hifi side?

I use a Crown Xti 1002 to drive my woofers with the built in X/O at 320Hz....works great for tight pounding bass.

It's all about that first watt.

I use JBL 4350A with JBL DX 1 active crossover and power them with FM Acoustics 600A and the preamplifiers are Dennesen JC80......pure fun!
