Sub sat with an integral active crossover allowing the user to both variably time align the sub to the sats, but also allows adjustment to both the low and high pass settings. Brought to you by the genius of Arnie Nudell almost three decades ago, the Infinity Modulus System, frequency response +/- 2db 22hz - 45khz.
Powered by a pair of Belles Model I amps biamping the sats they really are something special.
Nice rig. Infinity was always a leader. Back in the late 70s I heard an infinity tower speaker. Bass was meh, but the extension of the highs was in a league of its own. The KEFs and Brit mini-monitors couldn't match it. Unfortunately before I could get rich enough to buy a pair my hearing had declined to where I no longer noticed the difference. ):
It's never too late to turn back the clock.
All that's been said on the importance of a high pass filter when employing a sub comes down to one thing, how it sounds to you. Even though the Modulus system was designed with this feature, I still find it's best when not employing this option. I've owned the system from new in 1991, it's been used with Carver, Kenwood, McIntosh, Dynaco, Pioneer, and most recently a pair of Belles Model I amps.
Originally beginning with a Carver amp I used the high pass set at 120hz, this worked great with 350 watts / channel on tap, very holographic. But later moving to the Mac amp I found it just sounded that much better with less electronics in the signal path, feeding the amps directly from the preamp. Sure it wouldn't handle as much power, but these little beasties can take some serious juice and play quite loud full range anyway.
Over the yrs I've tried both setups when changing amps, but have always preferred the sound signal uninterrupted from pre to power for the mains, even with the ability to choose where the high pass is set.
