Heck my designer mandated all of my screen and sub channels to be ran off of 220v for maximum headroom and clean power.
Amp clipping sucks as well! You all have set up your gain structure properly to maximize the voltage coming out of the sub amps, right? Your amps are clipping at the same point regardless of the subs being connected or not, right?
For anyone following along that isn't quite sure they have their gain structure set to optimally get the very most out of their amps/speakers, here is a very easy to follow procedure to follow. It's lengthy but written to be easily followed.
Thanks for the info.
What I'm after is to maximize my drivers in my application. >30hz satisfaction was reached with 18's, I'm sure I would've been fine with 12's. I like the full spectrum of frequencies but I adore the single digits. I've always had a passion for sound, high quality sound. I compromise for the most part but not when it comes to the first octave.
I'm totally happy with the BHS24's. However, to maximize their potential in my application I either need to upgrade my amplifiers for more available clean wattage or I use bigger enclosures to pull more single digits. Sure, I have the minidsp boosted around 10hz with a low shelf but in my sealed enclosures I run out of wattage way before they reach their potential.
Which brings me back to either try and sell my cv5 amplifiers to buy 220v 10k watt amplifiers or keep the cv5's and make the enclosures bigger. I really like the cv5's reliability long term. We used them leisurely in the USN (submarine sonar) as well as knowing people that used them for years in the civilian world. I wish I could get my BHS24's dual 4 ohm voice coil, I'd put 2 cv-5 amps on each driver but that's not an option.
I rarely push my toys. However, when I feel like a session, I want to experience the effects of the BHS24's single digit potential, in my application. Ported and IB aren't my preference. For my ears, sealed is the only option. Had I known I'd end up upgrading to this house furniture/pieces of art, I would've built 34-36" square enclosures initially.
Such is life, forever evolving...
