DescriptionManualsrelated itemswarranty
With 70 watts of clean power and a full feature set, this amplifier offers exceptional performance and value. A class-AB output stage and a large power supply section give this amplifier great sound quality, and enough power to drive most compact subwoofers. The auto-on circuit and sealed rear enclosure make this amp excellent for upgraded computer subwoofers, and also for driving individual tactile transducers. Don't let the modest price tag fool you-- this is a workhorse amplifier that delivers just the right amount of power. Specifications: Measured power output: 45 watts RMS into 8 ohms @ 0.1% THD, 70 watts RMS into 4 ohms @ 0.2% THD. Signal to noise ratio: 90 dB (A-weighted). Dimensions: 7-1/2” W x 8-11/16” H x 3-1/2” D. Enclosure cutout: 6-5/8” W x 7-3/4” H.
  • Line-level and speaker-level inputs for connection to any system
  • Auto-on circuit comes on the instant the amp is needed
  • Variable 2nd order low-pass crossover from 60 Hz - 200 Hz

good amp for small sub
Monday, October 19, 2009
PE Customer from USA  

good amp. have used this twice now for small subs. once with the 5" tang band's in the sides of mini-towers, and once in a Triska. Good amp, but can get warm, and wish it had a heat sink sometimes.

Don from Pahrump, Nevada  

Needing a subwoofer amplifier for my new receiver I was at a loss as to what to purchase. Parts Express was very helpful in assisting me with this purchase. The amp works perfectly, once I determined the correct settings in my receiver. Thanks Parts Express.

This amp is a wee bit to small for Home theater, but I used it for Computer Sub. Class AB quality amplifier, with plenty of versatility, I even connected an MP3 player to it and Two Altec Lansing satellites coupled with with amp driving the subwoofer sounds is Awesome.
