JL Audio W7s for hi fi ??

Thanks, my question was not so much about Ripoles but more about the suitability of this driver for hi fi use given that its aimed at the car audio market. Is it just about volume (huge Xmax) or is the sound quality also good?
 
The JL woofers are very high quality and I don't think you'd be dissatisfied with the quality of the sound but there may be better options. Those in that thread would know more about what that enclosure works best with.

Many times, the Alpine Type R woofers are noted for good sound quality if you don't need the power handling of the W7. Check the reviews at Amazon.
