  1. Barely stronger. You need to add fiberglass layers to it if you want stronger. It actually makes it yield less but crack easier. The the ultimate strength isn't lowered though if you understand what I mean.

    However, it makes things very smooth inside but you will have to sand it still. You should gain unless got the inside to be smooth as hell already.

  2. its tuned to 39hz and the -3dB point on the lower end is 32hz. -3dB because that's when you will start to hear a noticeable change, for normal ears. Basically.

    It depends on a lot of things if the sub will bottom out at 32hz or not. You should have a subsonic filter and use it according to the loading and power you have.

  3. I'm surprised to see this thread by you. A SF won't cause clipping. It just blocks out frequencies lower than what its set to, and allows higher frequencies to play. Pretend its a highpass filter. It should be set about 5hz lower than box tuning.

    Not necessarily. My 18" AA avalanche in 10+ cubes tuned to 20hz needs no subsonic filter on 800 watts. Hell, it is barely at xmax full tilt with slight clipping. I built a box recently for a 18" Fi BTL in 8+ cubes tuned to 33hz on an AQ 2200 and the subsonic filter is at around 20hz. It was able to play a 20hz tone at full tilt with slight clipping and it was within xmech. Also, remember that filters are sloped cutoffs and not just a straight drop off. That's why it may be slightly louder at, say 35hz, when you turned the subsonic down, from say 25hz to 20hz.

  4. Get the AP line. Best money per performance you can buy. And I keep forgetting to get someone with an audiopipe amp to come over so I can oscope it and see the "dirty" power these others all cry about. Its funny that some people don't even own a oscope and say that the audiopipe amps are dirty and they don't think their high dollar amps are running dirty either. I guess people have oscopes planted in their brains.

  5. Just wanted to share this because the owner was extremely happy with it.

    A short video made by the owner but camera didn't pick up the flex that he had. the seats were going crazy and he had wiper flex too. His ashtray was being pulled out by the bass. Its pretty musical to me.

    4.75 cubes tuned to 34hz with kerf port. Amp is a Soundstream TX1 2000D with a deka 9a31 with stock alt. He is saving up to go 3k and a DC Power HP alt.

    He didn't specify a color for the port so I kept it bare. He said he will paint it red to match the red FI logo on the BTL. :)

    Also, the owner switched from two 15" AQ SDC2.5s in a tiny weak box tuned high to a single 15" BTL with my box. He definitely noticed an increase in output. :) He demoed for a buddy and the buddy had to bail because it was too loud lol.

    We got some meter time for this setup. Loudest I think was 145.6dB at 36hz on passenger windshield. Didn't do any at headrest and he did basically the same on the driver windshield. All this is sealed up. 140s at 30hz and I think his peak may be 43-45hz because he did 145s around there too. It sounds awesome. We only had music, no test tones.
