Modular Outboard Subwoofer Amplifier
Modular Outboard Subwoofer Amplifier
Unique Modular Cube Shape - fits anywhere, looks beautiful from any angle (except the back (where all the cables and controls are conveniently located and out of sight)).
New New! We are now offering a budget friendly ultra compact 6" x 6" x 6" cube fitted with a low power 25 Watt Dayton amplifier for just $125!
Note: The 25 Watt amp is only recommended for the Marlins or Orcas. For the Tritons, the 75 watt Dayton or 200 watt Hypex amplifier are the minimum power recommended. Furthermore, for the ultimate Orca or Marlin experience, the 75W Dayton or 200W Hypex are recommended as an upgrade over the new budget friendly 25 Watt Dayton model.
Price is for a single unit.
Ships worldwide from Seattle.
Orders are pre-paid. Current lead time is 2-3 weeks.
60 day in-home audition, 1 year warranty
Basic, no fuss, bi-wired speaker-level inputs.
The speaker-level input method (with our specialized Anchor Chain cables) does not affect the sound of your full range speakers.
RCA inputs can also be used to excellent effect, and we recommend our Bowline RCA cable for this connection method.

Recent design changes Dec. 2015:
We are now making and shipping all Outboard Subwoofer Amplifier orders in a new, same-as Benthic Bass Unit width-and-depth wood chassis.
Passive design, and an isolating subwoofer amplifier chassis:
We have been using various Dayton subwoofer amplifiers for 7 years now, and they 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. We now use low durometer urethane feet (like on our new speakers) to accomplish the task of damping out unwanted vibrations and resonances that make it to the wooden chassis.
Subwoofer Amplifier Option 1 -
Dayton 70 Watt Class AB Solid State monoblock subwoofer amplifier - This high quality, reliable, heavy duty subwoofer amplifier is almost triple the power output of the prior 25 watt standard subwoofer amplifier that we were installing in the now discontinued Dungeness active subwoofers. It is a perfect match for a single subwoofer in all but the more extreme fidelity stereo setups in which case the higher end Hypex best applies. While the Hypex is an improvement, the Dayton delivers fidelity and performance beyond our already well reputed subwoofer designs.
Subwoofer Amplifier Option 2 -
Hypex: 175 watt Class D monoblock subwoofer amplifier, manufactured in the Netherlands.
This amp has an ultra clean input stage, which gives excellent dynamics with low idle power consumption when used in conjunction with boutique quality stereo equipment or in higher power situations (like driving an Octopus Line array of Benthic Bass Units to the most extreme levels of grand dynamic range and/or volumes with clarity). Another factor is associated equipment: If you've really splurged on your main stereo or home theater amplifiers, then look no further than the Hypex option. The final consideration would be heat, as in the case of idle consumption, and during all but the most taxing demands on power output, the Hypex will run cooler and will comsume less energy than the Dayton Subwoofer Amplifier.
Hypex amplifiers are a relative newcomer to our lineup, but they have passed numerous rounds of long term testing and they sound flippin' fantastic with our gear. The crossover quality is truly first rate. The Hypex amp seems to improve the sound of the fullrange speakers just as much as the sound quality of the subwoofer because of its load behavior on the rest of the signal chain, even though the amp is only tailoring the signal going to the subwoofer driver (I.E. the fullrange speakers are left to run truly full range on their own, without any artificial signal filtration).
Hypex amplification is a popular choice for high quality energy efficient high fidelity full range amplifiers, like the popular NAD 3020, which is a favorite high efficiency high fidelity pairing with our Marlin, Orca, and Triton speakers as well.
The Outboard Subwoofer Amplifier is a single subwoofer amplifier (Dayton SA70 or Hypex DS 2.0) mounted in our Birch Ply 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 our Benthic Bass Unit. Input cabling accepts either speaker level (Anchor Chain Cable recommended) or line level (Bowline RCA cable recommended) inputs.
We recommend feeding this subwoofer amplifier with a stereo input signal via a stereo pair of Anchor Chain cables, as the internal circuitry of the amplifier will sum this stereo signal to mono subwoofer speaker level outputs via the binding posts on subwoofer amplifier case. These binding posts outputs are then wired with a single length of conventional speaker wire like our Mainsheet speaker cable to the passive subwoofer cabient like the Benthic Bass Unit.
Can I feed this amp with a single RCA cable from the back of my pre amp or home theater receiver?
The answer is 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 is critical for the optimal performance of the active crossover circuitry of the Dayton SA70 when using a single subwoofer.
A note about using Dual Mono subwoofers- When two passive subwoofers are being used, two Outboard Subwoofer Amplifiers are needed. 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 the subwoofer amplifier.
