Boston 8.5LF Pro Series Subwoofer

When Boston was testing the prototypes for the new ProSeries subs, the subs actually handled more power than their most powerful test amps could dish out. In fact, one amp gave out before the Pro Subs ever broke a sweat (May it rest in peace). How did they accomplish that? Pure engineering. Pro Subs handle a lot of power, because they've worked out new, innovative ways to keep them cool. Like using die-cast aluminum baskets that act as massive heat sinks. Or by employing a pretty sophisticated (and patented) venting technology called RadialVent™ Cooling. Then they engineered ProSeries to deliver in the SPL department. High mass cones and pliant surrounds deliver lots of incredible, tight bass even at high volumes. And a double-stacked magnet motor assembly concentrates energy where it can do the most good. Finally, they optimized ProSeries subs incredible output from small enclosures, so you can put more subs in an equal amount of space. The result: the cleanest, loudest sub you'll hear in your lifetime.

There are two and four Ohm configuration models available. Which one should I buy???
