The PAC TM-100 Tri-Way crossover allows you to power a pair of stereo speakers and a subwoofer simultaneously from a Tri-Way compatible 2-channel amp. It's a cost-effective way to drive a subwoofer.

The TM-100 has input and output wires that you connect to your amp's speaker outputs and to the wires leading to your speakers. A 12 dB/octave low-pass filter sends frequencies below 100 Hz to your subwoofer. A 6 dB/octave high-pass filter sends frequencies above 100 Hz to your main speakers. Handles 250 watts RMS per channel. 4-3/4"W x 2-1/16"H x 3-13/16"D. 1-year warranty.

Important Note: A Tri-Mode or Tri-Way compatible amplifier is required.

Sweet Tri-Mode Crossover

Written By Danskota, Albany, NY on Tuesday, October 14, 2008

Crutchfield Customer Review (What's this?)

Fast shipping, and works great! I connected this crossover to my old Tri-Mode 2-channel 60watt/ch amp with an 8-ohm single woofer. It is a bit bassy, but this is a good problem to have! Cheap way to liven up your sound. Can even drive 4 6X9's in series (no fader) for the hi pass...so 5 speakers off of a 2 channel amp! When using any Tri Mode crossover remember that your woofer will be bridged, so divide your impedance by 2. Your amp will see a 4ohm woofer as 2ohms, or 2 4ohm woofers wired in parallel as 1ohm...too much for most amps. Stick to 8ohm woofers and you'll be fine.

This works well driving my 6 1/2" components and an 8" Bazooka using a Profile AP400 (65 Watts/Channel). I'm sure the sub could hit harder if it where on the amp by itself, but I'm more than happy with the overall sound of the system.

Ok solution

Crutchfield Customer Review (What's this?)

Great for the price, i have a Sony XM-2200GTX and two 200 watt 6x9's and a 10 inch sub... sounds average, actually the bass is stronger than normal, i wouldnt recommend this if you want a lot of bass i should have just bought 2 subwoofers instead of powering the rear speakers and a sub.... but hey it does make my ears ring.... :P

Works well, for those on a budget

This thing worked well for several years. A year or so ago something inside must've come loose or burned out because the sub was no longer functioning.
