*** All of this gear has been sold *** Here's what I have: (2) AE - Acoustic Elegance IB15 drivers. These are the 15" drivers sold by AE and designed for infinite baffle use. These are the single 8 Ohm voice coil versions. AE IB 15 Speakers: $150 + 1/2 of the shipping for the pair. (shipping: approx. $30.00) Reason for selling? Well, frankly, I might be one of the few maniacs who lives in a townhouse with such a sub setup. Even though such a combination is very cheap bass, it was way overkill in my situation. My experience with IB? Well, it was a good one. Certainly, if you have the capability to install such a sub, you get a tremendous payback for not-so-much money. Please E-mail if you have any questions. Thanks.
