  4. New Tempest-X2 15" Slot Ported Design (Sketchup Attached) - Feedback Appreciated

    DIY Subwoofers - General Discussion
    Hello All, I'm planning a new 15" slot ported design, probably based around a Tempest-X2 driven by a 500W plate amp or 1000W standalone amp (haven't decided). The subwoofer will double as an end-table and will be replacing an Epik Valor. External dimensions will be 24H x 20W x 28D, 3/4" MDF...
  5. Tempest-X2 Sealed 8cuft / EP4000 - proper gain?

    Subwoofer Amps | High Pass Filters
    So, I finally finished my 8Cuft sealed Tempest-X2 sub..... and I have to say it's SOOO nice to have a sub that can handle everything that I throw at it! A 15" high excursion driver just doesn't compare to my poor HSU VTF-1 (although I have to say that VTF-1 sounds great for music and the volumes...
  6. Tempest-X2 Build / Polyfil vs Acousta-Stuf

    DIY Subwoofers - General Discussion
    So, I'm nearly done with building a sealed 8 CuFt enclosure for a Tempest-X2. I'll get some pics up at some point but right now it needs some finishing work... I'm struggling to find the motivation to sand/fill/paint it up since I'm going to have it hidden under stairs... My question is - has...

    DIY Subwoofers - General Discussion
    Ok i believe i have the two subs that i am interested most in picked out. But i need to work it down to one. I want to build a ported box enclosure with a 4 or 6 inch port or ports. It will be used mainly for watching movies and playing xbox. So i guess what i am after is which driver will give...

  9. Two Tempest-X2 Large Towers

    Ported Subwoofer Build Projects
    EDIT: Final design is 11.6 ft^3 tuned to 14Hz (see post #8) I'm about to start building two Tempest-X2 subs to fit behind my screenwall. Depth and width are limited, but height isn't, so they need to be towers to have any large volume. After running a few WinISD sims, I've settled on the...

    Hi there, Just want you guys to check something for me. A guy was running simulations with his Pioneer 12 driver : http://www.pioneer.at/eur/products/TS-W308D2/print.html And was comparing it to the Tempest X2 15 inch driver ...
  11. Tempest-X2 + Dual PR15 - Comments?

    DIY Subwoofers - General Discussion
    Hi Looking for input/advice on this setup. Single Tempest-X2 with two PR15 Passives. 130L enclosure (4.591Cuft) 700g on each passive Qa of 40 in WinISD (moderately stuffed? Still not clear on the way WinISD computes stuffing). Graph has a gentle rise of less than +1dB over the range of...
  12. How many passives with a Tempest-X2

    DIY Subwoofers - General Discussion
    Howdy - Very generic question with yet no real modelling done; How suitable is using a single PR18 with the Tempest-X2? Can I get away with it or is it just too close for comfort to skimp on the extra unit for 'real-world' overhead? I would be looking to tie it with a steep subsonic filter to...
  13. ?'s about Tempest-X2 build

    DIY Subwoofers - General Discussion
    Kevin or other knowledgeable persons. I plan on using the Tempest-X2 in my enclosure. The external dimensions are 18 x 20 x 52. The slot port is 3 x 18 x 44. Do you think the port dimensions are good? I could take some length off if neccessary. The driver and port will face the carpet...
  14. Tempest-X2 15" Build for Noob

    DIY Subwoofers - General Discussion
    Okay So I was posting in Audioholics forum and I ended up here deciding to research building a DIY subwoofer using the Tempest-X2 15" ($220). I want to send the box plans out to a cabinet maker for construction and finishing. I will be using it for 80% music (rap, techno, hardcore rock, I want...
  15. SDX15 or Tempest-X2 tests?

    DIY Subwoofers - General Discussion
    I've been searching the 'net looking for actual tests of these drivers. Ilkka has tested an early version of the SDX15 but not the current versions. Beyond that I can't find any tests anywhere for either driver. I'm looking for real world distortion, power compression, frequency response...
  16. Tempest-X2

    DIY Subwoofers - General Discussion
    I have built a sealed enclosure for the shiva-x2 at 3.66ft^3. While searching around on the diycable website I run into the tempest-x2. Download the pdf and see it models fairly well in a 3ft^3 box. According to the pdf it can hit ~25Fs in the sealed enclosure. My question is will the tempest...
  17. Ported Tempest-X2 Design

    DIY Subwoofers - General Discussion
    I'm looking at building a ported Tempest-X2 to go with the two Kepler's I'm going to build. I'm thinking about doing something like Neo Dan's easy button end table or something of the sort. I'm a college student so no WAF to worry about but it needs to be transportable so I'm thinking anything...
  18. First Tempest-X2 Design -- Easy Slot Port

    DIY Subwoofers - General Discussion
    I have a customer with a CNC machine, that wants to pop out some cut parts for a Tempest-X2 slot port design. I've drawn this up to make it as simple as possible for someone to put together a killer sub, on a fairly tight budget. Design constraints were that it needed to fit on a single sheet...
