    The problem with this response is that you don't have full range speakers. A 48hz bottom limit with no tolerance is not considered full range when the lowest note on a bass guitar is 42hz, and there are bass drums and synthesizer notes that extend below that. A full range speaker is flat to at least 40hz, and an extended range speaker is flat to 20hz. The lowest note on the piano is 27hz, which is well below what your speakers can reproduce. You really need a good sub to fill out the bottom octaves of the musical scale, especially with a 48hz roll off point of your mains.

    I agree with you. If you can hear that a sub is on and working it's probably turned up too high. Audyssey a BFD or something equivalent does wonders in setting up and calibrating a sub. Ideally you should hear something missing when you turn the sub off.

    I have two 7 1/2 foot tall 12" diameter PVC (sewer pipe) tubes for my TL subs. First time guests almost always ask what they are. When told they are sub woofers they usually ask why aren't they on. Then, while playing some music and in the middle of a selection I turn them off. Everyone without exception notices the difference.

    BTW: Several years ago when I first built them I did a lot of experimenting with different crossover points. At around 100Hz they stopped being directional to me. I used 80Hz to make sure they would never be directional.

    A BFD is at the top of my gadgets to have list. Until then I'm using REW and my trusty Rat Shack SPL meter to dial in my subs.

    By doing that you're not correcting your subs' response are you?

    I’d love to see those! Got any pics to share?

    What does the REW do? I remember people talking about them but don’t recall their function. Is that just test tones of some kind?

    REW is a free software which allows you to model the FR of your subwoofer, using a mic and your computer's sound card (if i'm not mistaken).

    Oh... Room Eq Wizard. Duh....

    Thanks. My mind is still in slow motion today.

    I don't have a laptop (ironic that I buy & sell laptop parts) so I never used it. I've read that it's a great tool to use with the BFD to make your response perfect, instead of just pretty good.

    No problem. I need to get me one of those BFD.... first. Have you sorted your Maelstrom yet?
    I just finished a DIY sub a couple weeks ago, I need to get cracking on a thread + pics...

    I took readings and then made the adjustments that I thought would work. Then my Rat Shack meter sh.t the bed, so I don't know for sure how well I did. It sure seems to work great though.

    Finished a sub?! Dude, you are supposed to start the thread when you start the DIY.
    So spill it. What are you using for a driver, amp etc...?

    I'll just say that it's not quite as obscene as yours

    I'll try starting the thread this w-e

    Maybe. At this point, I'm still mad at it though.

    Mine is not obscene. Take a look at a few of the other DIY threads at AVS or HT Shack. One guy built a sub with 4 - 21" drivers and 8 - 21" passive radiators. I think he used 4 - EP4000's to drive them. (Or was it the Crowns?) I don't remember. But that's obscene. His house must breath in and out when he's got those on.

    Looking forward to it.

    Only as much as placement can do. I am using the Pass supplied active eq to flatten the extreme low end. A BFD is next in line for gadgets to buy. I'm looking forward to hearing what the BFD can do.

    Too many compromises, the 48 hz or so my speakers go to is fine until I can get new ones.
    Besides, I LIKE MY MUSIC loud, which works out better without a sub.
    When they started making sub-sat systems it was generally agreed that no matter how precise you get everything lined up, a classic two speaker system is superior to a
    sub-sat system, even if the bottom end is not as low.

    Turn your sub down and try again.

    I did, and was surprized at how good the sound was.
    MY SUB IS NICELY SET UP(Audyssey) but ABing between direct (no sub) and stereo, and
    I just prefer the sound without a floorshaker. In other words, only thing I want a lot of
    "bottom" end on is movies and women.
