Bridging Sonic Impact 2 amp

geopango · 15th October 2010, 04:33 AM

Hi
I am employing two Sonic Impact Gen 2 T amps to drive my midrange and tweeters in a three way active system. I am considering purchasing an extra gen 2 Tamp so that I can run two amps in bridge mode for the midrange drivers.Are Sonic Impact chip amps bridgeable? Please advise.

Not bridgeable as each individual amp chip is already bridged.

My concern is that the T amps power output of 15 watts per channel may not be adequate for prolonged hi level listening into a midrange driver crossed over at 330 hz with a sensitivity of 91db 1w1m.
I am using a Behringer dcx2496 to cross the drive units over with 8th order Link Riley slopes. By what ratio does the output capacity of an amplifier increase with the implementation of this kind of high pass filter? Is there a graph on an applet somewhere?

Zero because that T-amp's output power is limited by low supply voltage.

I did this awhile back but cant recall the ratios. Check out Elliott Sound for a good article on this. Also, Mr. Linkwitz discusses this on his website somewhere since all his systems use multiple amps and electronic eq/xo.
