  1. Fi q18 infinite baffle

    IB - Infinite Baffle Subwoofer Build Projects
    Well thanks to the great deal I managed to get from Sonnie I am getting ready to do 2 manifolds each with 2 18's. They will be installed in a full open basement, I am planning on using a inuke 6000dsp to power them, will this be ok power wise? And what sort of feedback can I get from fellow...
  2. Fi Q18 horn modeling/help needed

    DIY Subwoofers - General Discussion
    I have a pretty big area available for two horns or two drivers in the same horn...around 50" wide, however tall needed, and 21" deep. I'd like to have the mouth of the horns firing into the corner so going smaller on the width might have to happen. Not sure yet. I can't decide if I want the...
  3. Dual Fi Audio Q18 build

    Ported Subwoofer Build Projects
    I picked up a pair of fully loaded Q18's about two months ago and just got around to post the build log...between work, being sick, and having my tonsils and adenoids removed yesterday morning, I've had almost no free time. Good thing I had the box completed before I picked up the subs! Anyways...
  4. Top drivers currently available for a clean-output LLT/EBS Sonotube Subwoofer

    Ported Subwoofer Build Projects
    This feel that I have read the very thread I am starting a countless number of times; my problem is that I have been planning an LLT for a few years now and during that time have selected several favorite drivers--only to see the manufacturer go out of business time after time! Avalanche, Sound...
  5. Joe's dual Q18 build thread

    Sealed Subwoofer Build Projects
    Well I figured it was about time I start my build thread. I will be building 2 6ft3 sealed boxes. Each one will be housing a Q18. I start cutting wood on Thursday or Friday. I plan on building 1 box now and another in a few weeks. I still don't have an amp but plan on picking up one or two...
  6. FI Q18 ported opinions

    DIY Subwoofers - General Discussion
    Hello everyone, I am going to pick up a 2010 Fi Q18 from a guy on craigslist on Sunday. He said it was only used for less than 1 hour and wants $250. He actually has 2 but I am still undecided if I want both. Would anyone want to take a look at my WinISD file and see if everything looks ok...

    Does anyone know what the Le is on the Ficar Q18? I can not find it in their specs. Matt
  8. Q18 Dual Sono Build

    Ported Subwoofer Build Projects
    Dual Q18's in 700l Sonotubes tuned to 12.8Hz 30" Sonotubes cut to 67" and 8.4" ports cut to 31.25". Well, it all started innocently enough. I found that moving my living room HT stuff to a more dedicated basement HT enviroment lost a lot of bass. Research brought me here. I enjoy doing DIY...

    DIY Subwoofers - General Discussion
    Can anyone help me out with the "Le" of the Q18 Dual 2 Ohm? I am trying to finalize my enclosure and port sizes using WinISD. I am using 4 mH right now hoping it is close. Thanks, Bill
  11. Need to match output of my Q-18 LLT with something else.

    DIY Subwoofers - General Discussion
    I am in a situation where when I moved my theater downstairs the only place that I can put my Sono sub is totally dead. I loose almost all the sound to my stairs and into another room. The only alternative that I have is to change to dual subs, 1 on each side of my center channel. The area is...
  12. received my Q18 today

    DIY Subwoofers - General Discussion
    Hi folks, My two Q18 drivers arrived today. I would like to know if this is ok. It doesn't have the logo. I know it's just the logo but of course, it makes us feel when we don't see the logo on something we bought, we feel something is missing. And also folks, is it ok to drill holes because...
  13. Q18 sealed with LT?

    DIY Subwoofers - General Discussion
    Alright, I'm still procrastinating on any kind of build, but I am also still very curious about going from a ported 15" Tempest to a larger sealed Linkwitz Transform sub. So my question is this: How will the Q18 fare in this type of application? It should have plenty of power handling and...
