RM Series II satellite speakers: impressive as PC speaker

I bought a pair of used these "granite" satellite speakers and am using them as my main PC speaker driven by a DIY amplifier. Originally sold as a part of home theater speakers but I am impressed. Without a sub, I am lacking a little mid-bass region which I compensate with pulseaudio-equalizer but vocal-cymbols are clear and impressive. Anyone know their sensitivity and ohm range? Cabinets are heavy and made of stone/granite?5clthu4yn0fc.jpg

    Hello,
    Those were the satellites for the RM3000 system. Here is some information from HiFi Classics site:

    Each of the satellite speakers is a miniature two-way system with a 3-1/2-inch “woofer” operating above 200 Hz and crossing over at approximately 4,000 Hz to a 3/4-inch dome tweeter. The tweeter is protected against burnout by an internal autoreset protection device that cuts off its signal until the power has been reduced to a safe level. The tweeter is stepped back about 1-1/4 inches from the plane of the woofer to provide proper time alignment of the outputs of the two drivers.

    The satellite enclosure is made of a high-density, nonresonant polymer aggregate similar to the material used for high-quality kitchen countertops. The smooth, glassy exterior is resistant to physical damage, and each of the satellites— which measure only 6-3/4 inches high, 4-1/4 inches wide, and 5 inches deep, including the molded plastic grilles—weighs a surprisingly heavy 4-1/2 pounds. The crossovers contain second-order low-pass and high-pass sections designed to complement the time alignment of the drivers. In addition to its crossover network, each satellite also contains a 200-hz high-pass filter that protects it from being damaged by high-level low-frequency signals.

    thanks for your input, I wonder how to extend the bass a little without buying a "regualr sub"...

    @SeleniumFalcon suggested website with subwoofer matched with these..., thanks again.

    You could remove the internal high pass filter, however that would limit the power handling capability.

    You're not going to get much if any bass out of that 3-1/2" driver.
    In addition to its crossover network, each satellite also contains a 200-hz high-pass filter that protects it from being damaged by high-level low-frequency signals.

    If you remove this ^^^ You run a very good chance of too much cone excursion which will be detrimential to its lifespan. Your best bet is to find a small computer sub that has high/low level speaker inputs and outputs.

    computer subwoofer with 4 speaker terminal connection on the back or do I need 8?
