Hello all, and Happy Holidays! I'll start my new subwoofer project in January. So far, my older one met the dreaded WAF spot-on (a 214L Tempest). It wasn't too difficult, actually - I merely used laminate in the same color as the rest of the speakers, wall and floors. This time, it'll be a bit more difficult. I want to build a 175L subwoofer based on a Cerwin-Vega! car driver. I already tested it on a sealed 80L box and really liked what I heard. If everything goes well, I'll be building two of them - one for my HT, which uses very smallish black ProMonitor 80 speakers by Definitive Technology, and the other for my reading room, which has Energy C-1 bookshelf speakers. These have the light maple finish. So far, one of the subs has to have a flat black finish (the ProMonitor one) and the other a light maple laminate. But I'd like to make them as insconpicuos and nice-looking as I can. So far, I have come up with a very slim, tower-like design. But I'd like to see other options... space is a premium, too (since the rooms are not huge). Any help will be greatly appreciated Javier.
