I'm considering picking up a 13w7 off a friend but I wanted to hear what people thought about their output? Is a single sealed 13w7 with 1000w enough to keep up with well powered xs650'S and 4 rev 8's? I dont have the space to port it so I have to go sealed. The reason why I pick the w7 is the availability, sound quality and build quality from JL. But I want it to at least keep up without turning the rest way down!
The JL Audio 13W7 is THE reference sub. One of the W7 benefits is the added 'under control' excursion. But you do not get extra excursion and the required control without lots of extra power. At 40 Hz a woofer in transition is incurring over 90 'G's of force. That is a lot of mass and inertia to control. IMO, you want to get as close as possible to the 1500 watt thermal rating in an open field environment. The JL Audio Slash 1200/1v3 would be the perfect choice (rather than the HD1200/1). Or, you could run twin HD750/1s, with one per each voice coil. When you add in the 1" baffle and the recommended internal bracing, the 13W7 sealed enclosure will be over 2.8 cu.ft. external displacement....if you have the space.
Btw, the Arc 1200.1 would not be enough power to properly drive a 13W7 in an open towboat as it would be under 800 watts into a 3-ohm load with a 12.5 volt supply.
The 13" W6 is disco. You could build a bass-reflex enclosure for the new 12W6 within the same external displacement as a sealed 13W7 and drive the 12W6 with an HD750/1. Not the same beast as the 13W7 but a competitive output for less cost.
