ACI Subwoofer Accessories

High-Pass Filters
Check price or order

Passive high-pass RCA type plug-in filters are available from ACI to remove the deep bass from your main amplifier/speakers. These in-line filters allow greater dynamic range and clarity from the main amp and speakers because they don't have to work nearly as hard in the bass. 

ACI Filters can be used as long as you have line-level (RCA) inputs to your main amplifier. If you have separates, this will be no problem. If you have a receiver or integrated amplifier, it must have pre-amp outputs and main amp inputs.

ACI Filters are 1st Order, (6db/oct), and  resistively loaded to allow use with virtually any power amplifier. Choose between two crossover frequencies of: 65Hz or 85Hz.

Y-Adapter

Check price or order

Used to split a line level output into dual outputs. Use with shielded RCA interconnects. For example; use Y-Adapters at pre-amp outputs to get dual outputs. One set of outputs goes to the subwoofer(s), one set of outputs goes to the main amplifier inputs.

RCA Adapter (Female/Female)

Check price or order

Used to join two shielded RCA interconnects. May also be used to join the ACI Speaker Level Adapter to any RCA shielded interconnect

Speaker Level Converters

Two of these are supplied with each Force, Titan or Maestro subwoofer. The Speaker Level Converter converts an amplified, (speaker level), signal to the line level signal required by the subwoofer. Not required for line-level hookup. 

The converters may be installed directly in parallel with your main speakers. This can be done at the speaker outputs on your receiver or amplifier. Alternately you may put these in parallel with your speaker at your speakers input terminals. You may attach any type of speaker cables to the speaker cable end using either electricians twist nuts or a twisted, soldered and wrapped connection.  If running shielded interconnects to sub, you will need to purchase RCA Female - Female adapters.
