  1. Ported Subwoofer Build Projects
    Hi Everybody. I am hoping someone can help me with my proposed sub build. I have a couple of empty sub bins that housed dual 18" woofers. They were originally used for commercial cinema duty and are each around 550 litres gross internal volume. Just to clarify, the 550 litres is measured...
  2. General Service and Technical Information
    Hello, I build my first sub a while ago, the box is terribly made so when it started rattling at any audible volume I though it was just my terrible box. Recently I had another look at it and touching the cone fixed the issue. Running an oaudio 300w amp though it might be clipping the poor...

    In Oz its difficult to find decent large capable drivers for under $400.00. I'm looking at either Dayton Audio Ultimax 15 in a 170L sealed box or Mach5 IXL 18.2.2 in a 170L ported box ( 17hz tuning). I've modeled them in winisd but the real issue for me is the sound quality. Has anybody heard...

    Disclaimer: I have no affiliation with this company. I chose them based on recommendation from Steve Callas and because they're a Canadian company which saves me a lot on cross-border brokerage fees. To be blunt, some of the best customer service I have dealt with. I contacted MARK in...
  5. Ported Subwoofer Build Projects
    I'm playing around with Sonosub.exe and winISD and have come up with some measurements. A few questions: First: The area after(lower) the tune frequency, should I put much thought into this ? I was under the impression that below the tune frequency, distortion rises quickly. So for example...

    Hey All, I am in the process of Aquiring 2 IXL 18.4 Drivers and was wondering about getting an Amp with Built in DSP.. Now My Question is I hear say like the Behringer iNuke 3000 the High Pass filter Bottoms out at 20hz, Since my Subwoofer tune is 16hz how can I get the DSP to go lower to fit...
  7. Classifieds - Speakers and Subwoofers
    I have 4 IXL 18.4 subs BNIB, never opened. I also have four used IXL 18.4 subs that I'm willing to sell as well. I've decided to do an IB with 8 Fi IB318 woofers. These IXL's would work IB, but they are really designed for LLT. Looking to get $150 ea for the used ones and $225 ea for the new...
  8. Ported Subwoofer Build Projects
    So I'm going to finally build the rest of my IXL 18.4's into my theater. I originally bought 8 around five years ago with the intent to go IB, but for this particular application in our new home it looks like I'll be better served going ported. My better half has given me a nice chunk in each...

    seeing how my sealed enclosure is nearly finished and i'm now quite comfortable with a sub build, i would like to hear any feedback on my next multituned slot ported enclosure. i'll be using mach 5 ixl15.2.2 with a behringer ep4000 to drive them. each driver will get one channel. i'm guessing...

    I have been tinkering with an IXL 18.2.2 build and have come up with this. Can someone look at it and see if I am doing it right and if it looks correct, or maybe even suggest something else? Thanks.

    Hi All I purchased a Mach 5 IXL 15.2.2 driver based on a suggestion from Graham (Gperkins_1973) and in part because Mike P. built one and seemed to like it. I'll be posting my build here to thank the community, especially Graham and Mike P, for the input. I am nearly complete with my build...

    Well i finally built and my dad finished his sub. Its pretty much exactly the same as mine except for the driver. Mine is a Tempest-x2. Only reason for this is I built mine and was traveling. my dad was using my sub and wanted to build one for himself. So he got the wood all cut and wanted me to...
  15. Ported Subwoofer Build Projects
    Hello After months of reading on this forum and weeks of working with Graham Perkins (another Graham Perkins design) I have started to build 4 IXL 18.2.2 10 cubic foot subs tuned down to 15hz. I have all the parts with the exception of the 2 Berhinger EP4000's. These subs are to replace one 12...

    Was looking at CSS and saw the PRs, and tossing the idea of a 18 " IXL and dual PRs, wondering what size box I can get away with and would the 1600 or 2100 grams work best? Was just thinking I can keep it relatively small if I use PRs over an LLT, as I "can" squeeze and LLT but I lack tools and...

    Hi guys, I'm doing a sealed 200L box using the Mach5 IXL 18.2.2 driver. Just ordered the IXL 18.2.2 driver and i've been reading so much on this forum about DIY and how much fun you guys are having with it. I'm doing this simply to build a great sub whilst keeping the cost low (cant afford...
