  1. IB - Infinite Baffle Subwoofer Build Projects
    Not sure If im modelling this correctly. This is telling me that I'd have to go up to 600W per speaker to hit Xmax. I've read in other places that 250-350w would be the most you'd want to go with dual opposed IB318 subs to prevent from bottoming out.
  2. Ported Subwoofer Build Projects
    Has anybody tried to model the new Mach 5 UXL-18 for an LLT build? I'm trying to follow the basic idea laid out in the LLT Explained post, but I get a hump around the tuning freq. when I model a larger enclosure (~650L). I can't seem to get the desired 4db/octave roll-off above the tuning freq...
  3. DIY Subwoofers - General Discussion
    I know I am doing something wrong, but I don't know what. I am trying to model with WinISD, but when I change box volume, it isn't doing anything that makes sense. I uploaded the graph. When I change my box volume it simply raises or lowers the peak at 17 Hz. The graph looks fine in a 1...

    I would like to know more about the amplifier requirements caused by EQ and how to model this in WinISD. In another thread I came across this regarding WinISD and EQ: It was my understanding that to correctly model EQ power requirements in WinISD, you utilise the fact that for every 3dB...

    Got some 20" sonotube and 6" PVC for the port and I plan on getting an SDX15 coupled with a BASH500. Want to dig as low as possible and this is 100% home theater (Blu-ray). Was thinking around 400L, but there is NO WAF, so can go as big as I want..... Ideas?
  6. DIY Subwoofers - General Discussion
    I've been modelling different drivers in an IB config with different amounts of wattage powering them as well as SSF's at differing frequencies and variable single band parametric EQ boosts at various frequencies (like what could be done with the Reckhorn B2). It's pretty cool. I'm a little...
  7. DIY Speakers
    Is there a software package (free?) in which you can actually model the speakers in 3D and calculate the parameters/specs, etc. at the same time? Or is there only the numbers and graphs versions?
  8. Mobile Audio
    Hello! In home audio we figure room gain is about 6dB/oct below the lowest room node. How do I figure cabin gain for a small car? I'm thinking of using an RL-p12 for a SQ setup. Nothing very fancy, but definetly no boombox. I'm thinking separates up front and a ported box in the boot. The...
