I have recently fallen in love with a pair of Proac response 1.5s at my local audio dealer. However, it is easy to see that they are way overpriced. The treble and midrange are beautiful, with a huge soundstage. The bass, on the other hand, is anemic. How difficult do you think it would be to build a Response clone, which is a short, narrow tower, and then put a larger box under each tower with a down-firing woofer and crossover? I would love to hear any suggestions!
