SM 155 Infinity speakers?

Question

A picture of  a 1990's, Floor model Infinity speakers, model # SM155

Answer 1

 The infinity SM/155 speakers are by far the best speakers I've ever heard. These are the biggest monitors in the SM Series with 15 inches woofer.  If you want to know about the product specifications, I have detailed them below:

Frequency Response of the SM 155 Infinity speakers is 29Hz - 27kHz

Crossover Frequency(ies) 500Hz, 5.5kHz

Sensitivity is 102dB (1 watt/1 meter)

Power Rating: 10 - 300 watts

Nominal Impedance Compatible: w/8 ohms

Woofer 15" (381mm) polypropylene coated

Midrange Driver TWO - 4.5" (114mm) polypropylene coated

Tweeter 1" (25mm) high-output polycell

The bass of the SM 155 Infinity speakers is strong and deep midrange but u have 2 turn up the sound to get the real bass sound.

Answer 2

SMS 155 Infinity speakers are the best speakers, the huge bass driver makes powers subs obsolete, I have Bi-Amped my system using magnet MA-300F,300W-RMS Amps driving each speaker and they hum, clarity at high volume levels which I found with these speakers. One weakness is that they are so heavy to move around. You can use a paddled dolly and some bungry cords for it.
