This subwoofer is huge and beefy and is in the heavy-weight division weighing in at 37.5 lbs. The magnet is a 246 Oz (15.38 lbs). This sub has our best cooling technology which means even if you are entering competitions and playing 1 minute test tones it will handle it all day! We added a thick aluminum ring near the t-yoke that absorbs and dissipates a ton of heat. We also used a much thicker T-Yoke and washers which also absorb heat. The voice coil we use is 3” and is rated to handle heat up to 250 Degrees Celsius. This sub is engineered and built better than other subs that cost twice the price. Recone kits are available and this item includes a 90 day money back guarantee. If you don’t like it we will send you a return label and take it back and give you all your money back.
