Infinity IRS BETA

Oh, yes, v-e-r-y much so!

They thrive on power!

Be sure you can get them fixed if needed (especially listening to loud Rock).

Pretty Sophisticated Speakers. Exciting, Best of Luck with them.

Many of you know I am a big fan of level controls to adjust output to the space.

excerpt from this review:

"All the crossover filters for the EMI drivers are contained in the bases of the free-standing panels, as are the level controls for the three uppermost drivers. (The two LEMIMs are the only drivers without level controls, which is okay because all the others have them.) An electronic crossover (supplied) contains an active low-pass section, with response-contouring controls for the woofer towers, and a passive (straight-through) signal path for the upper-range panels. The Beta system must be bi-amplified, although it is unusual in that it feeds the full audio range to the upper-range amplifiers.

On the electronic crossover are a woofer level control, a crossover control—labeled "low-pass filter"—which changes the woofer low-pass turnover, a "high-pass filter" that establishes the system's LF cutoff frequency, a bass contour control (for rising, falling, or flat response below 40Hz), and a woofer polarity switch. On the rear of the crossover is a toggle switch labeled Open Loop Gain Comp, which is essentially a gain-compensating switch for the bass amplifier."
