Opus One A2451 Active Subwoofer 180W Amplifier Plate Module Adjustable

This completely self - contained amplifier module simply fits into the back of a subwoofer cabinet. The unit will automatically spring into life from its Standby mode once a signal is received. The Volume and Crossover Frequency Controls together with the Phase Correction Switch allows the sub - woofer to be set to the desired sound. Installation can be completed in just minutes, simply make a 235mmH x 175mmW cutout into the back of the enclosure and slip in the module. Overall depth is 100mm.

Features

• Auto power on/off with signal presence
• High and low - level inputs
• High - level outputs
• Volume control
• Short circuit output protection
• Active crossover variable from 20Hz - 200Hz
• Phase reversal switch

Recommended Project Idea:
Purchase an A 2451 and 2 x C 3088 8" Woofers. The ideal combination for a D - I - Y home theatre subwoofer. The 8" woofers employed to result in a compact enclosure that could easily fit behind or next to a couch. 

This project can be built to the following specifications: 
40 - liter enclosure 
70mm diameter port 
100mm port length 

This results in a sub enclosure tuned to 45Hz.
