What is it:
This Canton Hifi DVC Subwoofer was sourced from a passive 2.1 home audio subwoofer cabinet. Interior dimensions of cabinet 12" x 12" x 12", stuffed 50% with fiberglass insulation. This should play nicely in 0.8 to 1.2 CF sealed, use at least 50% polyfill or fiberglass if the enclosure is 1.0 CF or smaller. Less stuffing necessary if your cabinet is on the larger side. I do not have the tools to test the speaker's parameters, if you do have the tools, or the patience to experiment, this could likely be used effectively ported in 2+ CF tuned at ~30-40 Hz, just don't quote me on that. In the original cabinet, the manufacturer claims a usable frequency response of 22-120 Hz.

Physical characteristics:
  • Testing the subwoofer's suspension by hand, it has a rather soft suspension.
  • Rated for 140 watts RMS, 200 watts program. (Having been originally configured as a passive subwoofer, this relies on above-average efficiency to recreate low-range sound, an option that is too often overlooked in mobile audio.)
  • Subwoofer has a butyl surround and rigid, lightweight aluminum basket.
  • Total mounting depth is a very reasonable 4.25". There is no pole vent, so provided the box is adequately braced to prevent any flexing, the motor can be installed with zero clearance, though I would recommend 1/16" to 1/8" minimum as a best practice.
  • Basket is either powder coated or coated with a heavy-duty black paint, which feels somewhat plasticized on the exposed trim ring, which is stamped with the Canton logo. (The outer perimeter of the basket doubles as an attractive integrated trim ring, flush with or protruding slightly beyond the high point of the speaker surround).
  • The motor structure is appropriately sized for a subwoofer of this type.
  • The cone is very lightweight and fairly stiff, but not rigid.
  • The cone appears to be partially or completely glass-fiber based, or at the very least, coated paper with some glass fibers impregnated in the slurry during manufacturing. The inside surface of the cone appears to be raw/uncoated with the fibers arranged in a random-pattern, felt-like configuration (but stamped smooth), and the outer surface is either stamped or woven into a fiberglass-textile type surface. See photos for clarification.

Why do you need it?
First off, due to relatively shallow mounting depth, this is likely to work behind the seat of many single-cab pickups, or in the space available below the floor of an SUV without removing the spare tire.

Secondly, this speaker gives you the option to configure a low-wattage system which meets your needs at considerable savings compared to a less efficient subwoofer with a larger amplifier.

A few simple scenarios which capitalize on that relatively high efficiency, low wattage characteristic are listed below:

(1) Use 2-channel amplifier with a 4-ohm passive crossover to run this subwoofer AND your mid basses. I'd recommend an XO similar to this one: Home
(2) Use an active head unit which can be configured to run the two rear channels with a low-pass filter, sometimes used for small subwoofers in the rear package tray area. Apply one low-passed rear channel to each voice coil.
(3) Use a 2-channel amplifier in tri-mode - meaning you connect one set of 4 ohm coaxials or component speakers to each channel, AND connect the subwoofer, wired at 8 ohms with a passive LPF at 80 or 100 Hz inline with the sub. In the bass frequencies, your amplifier will see the same load as if it were bridged at 4 ohms.
(4) Use a small, 2-ohm stable monoblock amplifier, say 300W RMS or less, and you are disciplined about the gain settings so you don't toast the voice coil.
