Definitive Technology Super Cube Reference Powered Subwoofer [Expired]

no longer for sale


I honestly never thought that I will ever put up for sale my beloved Definitive Technology Super Cube Reference Subwoofer  but due to space limitations where I have to make room for my new Speakers I have not choice but to see if I can find a new home for this remarkable Subwoofer.
  If you are reading this ad is because you know what this Reference Subwoofer is capable of doing.  It is a beast of a Subwoofer . With its 14" woofer coupled to  two 14" ultra low base  passive radiators and an 1800 watts built in powered amplifier , not only this beast will shake the hell out of my apartment but the whole building. 
This Definitive Technology SuperCube Reference Subwoofer was purchased around 3 years ago from HI-FI Heaven ( an authorized dealer)  and it has been kept in a smoke/pet free home and it is in new condition. I take extremely good care of all my high end equipment.   It was shipped to me on a truck strapped to a pallet . This Subwoofer is heavy  105lbs out of the box and the shipping weight inside the original box (which I still have ) is 112lbs.  It measures  17"x 17" x 17"  out of the box.   I had to have a special built in dolly made with caster wheels to be able to move this beast around due to its weight . The dolly will be given to the new owner only if the unit is picked up at no extra charge.  Please ad 2.9% for the Paypal fees when  using Paypal for payment.

Please do understand that due to its weight I will not ship the unit . It will have to be picked up in Briardwood , New York. In the event that someone wants it shipped , the buyer will have to arranged with either Fed Ex or UPS to have the unit picked up and the buyer will take sole and full  responsibility in the event that the Subwoofer gets damage during shipping to fight with Fed Ex or UPS to get their money back. Just make sure it is fully insured.  
This Reference Subwoofer was discontinued years ago by Definitive Technology and they are hard to come by and that's  the main reason I didn't want to put it up for sale.  As you can see in the photos next to the Supercube Reference is my new Definitive Technology SC6000 which looks like a little kid next to his giant brother.
Thank you for your interest,
Carlos . 

The Super Cube Reference uses a 14 inch driver pressure coupled to two 14 inch infrasonic radiators, with the main driver powered by an 1800 Watt class D amplifier. All that size and power allows the Super Cube Reference to reproduce bass down to 11 Hz to foundation shaking levels. Housed in a relatively small 16 inch square by almost 17 inch tall cabinet that is covered on all sides by mesh with the top plate and bottom a high gloss black piano finish. The sub weighs a beastly 111 pounds and can rest atop either adjustable spikes or rubber feet. On the rear panel are line level inputs and outputs as well as an LFE direct, high pass and low pass inputs and outputs as well as continuously variable phase, level, high and low pass filters. The only thing missing are balanced inputs and outputs.

This subwoofer has an interesting design with the main driver firing forward and the passive radiators to the side, the grill mesh is more a tube stretched over the four sides with a draw string on top to keep it always looking taut. The build quality is excellent and the cabinet is rock solid. Fire this baby up and trim it in to your system and you will be treated to deep, accurate bass with seemingly limitless extension in both depth and volume. You can spend a lot more than the $1,899 the Super Cube Reference cost, but it would be hard to beat its performance at twice the price or more.
