  1. DIY Subwoofers - General Discussion
    I'm working on a small home theater and I want to tackle the subs. I've got spouse approval for dual subs if I keep them small, so I'm thinking ~1 cut ft sealed with some DSP. Keeping in mind that for me smaller is better... am I better off with two HO 12's or two Ultimax 10's? I havent settled...
  2. Home Audio Subwoofers
    I'm accumulating info on home subs to go with my main system. It's NOT a HT rig, it's going to be used for music only. The speakers (currently being refurbed by the factory) are a pair of Magneplanar Tympani 1C, which will be bi-amped. I'm in a relatively small room in terms of volume; it's...

  8. Sealed Subwoofer Build Projects
    The idea behind this was to serve as a coffee table of sorts under the screen. I built it with nothing but a circular saw so don't crack on it too hard. :) Almost finished, slapping on some paint right now and will wire it up in the next day or two. I have had two for about a year maybe, got...

    This all started a couple of years ago. But I didn't know it at the time. When I first put together my basement theater, I was optimizing for floor space, and budget. Because of that, I only purchased one SVS PC-13Ultra. The idea was that I would get another PC-13Ultra the next year or so...

    I am modelling two setups..... two LMSR 15's vs two Ultimax 18's in a 500 liter (17.5 cubic feet) box tuned to 15hz. I get a slot port length of 4 by 24 inches wide for 56 inches long. At 1000 watts both of them seem fine for excursion, and port velocity is 17 which seems decent. The...
  16. IB - Infinite Baffle Subwoofer Build Projects
    Well, I'd like to build an IB. After doing much reading it's apparent that the FI 18 is the industry standard for IB. The ultimax is somewhat new and I haven't read many IB builds using it, it looks good on paper, the t-s parameters show it to be a candidate, and I've always been a fan of...
