This is the problem; people see XBL^2 and think it's the end all - be all. Well, sorry folks; but no. There are multiple other ways to design a flat BL subwoofer; and the W7 incorporates one of those ways. The W7 is one of the lowest distortion subwoofers on the market. Also, XBL^2 is only a portion of the driver. You still need to design an entire subwoofer around the technology and that can and will vary the performance of the subwoofer as a whole.I hear the Avas will have better SQ since they are XBL^2,
Proof? I'd like to see empirical evidence to support that claim.and a more linear response,
FYI: The 13w7 outdisplaces the 15" Avalanche. By a large margin? No. BUT, don't claim something to be true that isn't!!I would bet they will out preform the W7's also since they are larger and also have a high excursion.
Please, explain how the W7 is obsolete considering, how many years later, it is still the reference subwoofer others are compared to, it is still one of the lowest distortion subwoofers on the market and one of the most accurate subwoofers on the market, and still one of the highest displacement subwoofers presently on the market.old design, made obsolete by some of the newer ones...
Refer to my above post about the 13W7's outdisplacing the Ava's.two 15" avas should be louder than two dub7's
