    DIY Subwoofers - General Discussion
    Hello fellow shacksters, has anybody tried modeling the Mach 5 Audio FTW-LTE? I am on deployment and my laptop crapped out on me. So if anybody can model the FTW-LTE for me, I just want to see how it simulates in a sealed enclosure. Thanks.

    Sealed Subwoofer Build Projects
    It's taken maybe 6 months to make a final decision but a few weeks ago I pulled the trigger on 2 FTW-21's and an iNuke NU6000DSP. I received the first FTW-21 yesterday and WOW!! I knew it would be big and I know how to read 21" on a tape measure but I don't think I had any idea how massive a 21"...

    DIY Subwoofers - General Discussion
    I'm contemplating a 2-18" subwoofer build, and I've seen quite a little discussion on IST's drivers, and oooooh yeah, the spec's look good.

    Ported Subwoofer Build Projects
    I need help with building a ported subwoofer with an IST Mach 5 18" (IXL-18) driver with a Behringer ep4000. What size box and port do i use to get the best sound? The driver site says 200 litres (7 cu.ft.) 19hz tuning. No size limits and will probably be down fireing (is this a problem?)

    DIY Subwoofers - General Discussion
    What would you do between 4 18" IXLs or 2 FTW 21" drivers. Looking to go sealed from ported. Yes I know, I didn't think I would end up thinking about it. I am waiting for a price back from Mark at IST about shipping to the UK but it would be good to get some opinions. 4 IXL's would be cheaper...

    Has anybody tried to model the new Mach 5 UXL-18 for an LLT build?
