Outboard Subwoofer Amplifier

Outboard Subwoofer Amplifier

from 125.00

Unique shape - fits anywhere, looks beautiful from any angle.

New shape! A budget-friendly ultra compact 6" x 6" x 4" cube fitted with a low power 25 Watt Dayton amplifier (for use with Orcas or Marlins) Or, optionally, you can opt for the more powerful 70 watt subwoofer amplifier option in the drop down menu if you are looking for higher volumes and/or stronger bass response than the 25 watt amplifier can deliver. For people looking to support the bass of their full range speakers but not annoy the neighbors, the 25 watt amplifier is an excellent option. And for those who have the luxury of being able to play their stereos at full volume, the 70 watt model will deliver the goods.

Price is for a single unit.

Basic, no fuss, bi-wired speaker-level inputs or RCA inputs - your choice.

Mono subwoofer driven with speaker level inputs: (2.1) Purchase one Outboard subwoofer amplifier (25 or 70 watt) 2 lengths of Anchor Chain input cable to drive this sub amp’s inputs and also one length of Mainsheet speaker cable to connect the single 5 1/4” Benthic Bass Unit passive subwoofer.

Stereo subwoofers, speaker level inputs: (2.2) Purchase two Outboard subwoofer amplifiers, two lengths of Anchor Chain input cable, and two lengths of Mainsheet speaker cable for two Benthic Bass Unit passive subwoofers.

The speaker-level input method with Anchor Chain cables does not affect the sound quality of your full range speakers.

RCA inputs can also be used to excellent effect, and I recommend my Bowline RCA cable for this connection method in that case, substitute one or two lengths of Bowline RCA (depending upon your pre amp) for the Anchor Chain cables in the above suggested setups.

Overview

The Outboard subwoofer amplifier is a single subwoofer amplifier (Dayton SA70 or Dayton SA25) mounted in the Birch plywood or Bamboo ply chassis and hardwired to a set of binding posts on the back. The setup facilitates the hookup of one passive woofer cabinet like the Benthic Bass Unit. Input cabling accepts either speaker level (Anchor Chain Cable recommended) or line level (Bowline RCA cable recommended) inputs.

These binding posts outputs of the subwoofer amplifier are then wired with a single length of conventional speaker wire like the Mainsheet speaker cable to the passive subwoofer cabinet.    

Dayton subwoofer amplifiers are known for good reliability and sound quality. These factors are both enhanced when the subwoofer amplifier is mechanically isolated from the subwoofer cabinet in its own separate outboard chassis. Low durometer urethane feet accomplish the task of damping out unwanted vibrations and resonances that make it to the wooden chassis. 

Dayton SA 25 is a basic, budget-friendly subwoofer amplifier in an ultra-compact 6"x6"x4" lightweight wooden cube (in your choice of finishe). The 25 Watt amp is only typically recommended for use with the Marlins or Orcas.  

Dayton 70 Watt Class AB Solid State monoblock subwoofer amplifier - This is a tried and true high quality, reliable, heavy-duty subwoofer amplifier that gives almost triple the power output of the 25-watt standard subwoofer amplifier. It is a perfect match for a single or dual subwoofer in a high fidelity environment. For the Tritons, the 70 watt Dayton is the minimum power and optimal crossover point recommended. Furthermore, for the ultimate experience with either the the Orca or Marlins, the 70W Dayton or is recommended as an upgrade over the new budget-friendly, neighbor conscious 25 Watt Dayton model.  

Can I feed this amp with a single RCA cable from the back of my preamp or home theater receiver?

Yes - if you are running this subwoofer in a home theater or active studio monitor type situation.  

Hooking up a Single subwoofer amplifier/passive subwoofer to a typical high fidelity 2 channel system

Feeding the subwoofer amplifier with a stereo speaker level input via Anchor Chain cables or Bowline RCA cables is critical for the optimal performance of the active crossover circuitry of the Dayton SA70 or SA25.

A note about using Dual Mono subwoofers - Whenever two passive subwoofers are being used with two subwoofer amplifiers, each subwoofer amplifier will have only one of its input channels being fed by one anchor chain cable plugged into the right channel of the high-level input on each subwoofer amplifier.
