In 2008 the Heavyweight V.2 set many world records in several classes. The 2009 version is even better with a much improved stronger cone and surround, 30% stronger triple joint, and boasting linear coil technology. The 2009 version handles more power RMS and plenty more for short bursts.
The Heavyweight is available in almost any custom coil configuration and can be built for ground pounder applications or for extreme SPL or a mix of both. If you want to win a championship or become the king of the block the Heavyweight is for you.
Here are a few of the Champions that used the Heavyweights
- Jim Pitcher - Pro stock 601-1800 - 162.9 with three 15"
- Jeff Sanford - Pro stock 1801-3000 - 164.1 with three 15"
- Robert Kollar - Pro stock 3000+ - 165.7 with three 15"
- Mark Brus - Stock 3000+ - 164.1 with three 15"
Those are just a few in 2008 and with many other great competitors using the Heavyweight we are sure many more records and championships will be taken.
