  1. what amp for 200 watt rms pyle bl1290 sealed home theater subwoofer

    DIY Subwoofers - General Discussion
    I plan on going 4.00 cf gross for the pyle sub sealed this gives it a center frequency of about 35 hz and a -3 at 27 hz. We could even stuff it for an even lower center frequency and lower qtc than 1.10. The subwoofer is dual 4 ohm so we would need a amp at 200 rms at 8 ohms. Any suggestions...

  3. Single LLT vs dual sealed vs dual small ported

    DIY Subwoofers - General Discussion
    I built a 12 cubic foot LLT about 3 years ago and I am very happy with it. My issue now is that there is not much transparency with a single sub. If you sit in one corner the bass is amazing, but it drops off drastically as you move away from the corner. The LLT was my first build and I did not...
  4. Powering sealed JL 13w7 EP2500 or XLS 2502

    Subwoofer Amps | High Pass Filters
    So I plan on building a sealed JL 13w7 with EQ to hit 20hz flat, to power that little beast I was wondering if I should get an Behringer EP2500 or a Crown XLS 2502. Personally I'd like to go with the Crown, better efficiency + no need of mods for silence, but I wonder if it can handle the task...
  5. RL-P18 in smaller sealed box?

    DIY Subwoofers - General Discussion
    I've running my pair RL-P18 in 8ft~3 sealed boxes today but I would really like to use smaller cabinetts instead. Have anyone tried RL-P18 in a smaller box for HT use, i.e. 4ft~3?
  6. Twin Avalanche 18", Sealed or PRs?

    DIY Subwoofers - General Discussion
    After MONTHS of kicking around ideas, I finally have started a build. I’m looking to build new subs because I want to get better low bass output then my present sub offers. So after shopping around and doing countless drawings and plots, I made a deal to purchase 2 Ascendant Audio Avalanche 18”...
  7. Advice On Sealed Sub?

    DIY Subwoofers - General Discussion
    Due to the thousands of posts on subwoofer design a request for some design suggestions from the more experienced is almost a necessity. I'm a veteran cabinet maker and have a good feel for some of the software packages available so all I really need is a few suggestions to get me going in the...

  9. Sealed, Ported, Bandpass, ABC, Dual-reflex?

    Mobile Audio
    Hello...I'm just looking for some input on a subwoofer box I am about to build. It IS for the car (a van, actually) but my questions concern box types and response in general, so I thought I would get more feedback here. I have a TC-9 motor and 15" 12 spoke frame that I plan on building with...
  10. Any sealed ZRT builders out there?

    DIY Speakers
    I just ordered the ZRT component kit from Madisound using reduced BSC for nearfield use (home studio). I haven't ordered cabinets for them yet, and will be doing a sealed (acoustic suspension) version of the design. Has anyone out there done this yet? What volume cab did you use? Thanks!
  11. The JL Audio 8w6 Sealed Sonotubes Project

    Sealed Subwoofer Build Projects
    Eventually these will be complemented by a TC Sounds ported tc1000 sonotube. But I want to get these drivers put to work. I'm trying out a some small sealed sonotubes to see how they sound. Lack of table saw and space make this the easiest option. The rockwool and sonotube are on their way so a...
  12. Sealed DIY options?

    DIY Subwoofers - General Discussion
    I am planning to purchase a pair of subs by the end of the year, and want to be thorough about considering all options. While I am convinced that DIY gets a better product for less money, I don't see myself getting much shop time in the near future. However, if there is a good option using...
  13. Use my TC 3K PR sub for 50hz/below bass and the AE AV15X sealed sub for 50hz/above?

    DIY Subwoofers - General Discussion
    Since my AV15X sub was being repaired, I have been using my TC 3K 15" sub in the 7cf with 18" PR's tuned to 15.5hz. Actually, the box is more like 8cf since I added 5-lbs of polyfill material to it. I just received my AV sub back and I've been thinking of letting the TC sub use the PR box and...
  14. Sealed Sonotubes - How to fill with pollyfill and calculations

    DIY Subwoofers - General Discussion
    I am looking to extend the extension of my dual stacked 6'cu 19ov.02 sealed sonosubs. I really don't want to disassemble them and add poly fill unless it is worth it so that leaves me with 2-3 questions: 1. Can pollyfill rest on the back of a woofer on a downward firing sono? 2. How much...
  15. FS: TC2000 sealed sub

    Classifieds - Speakers and Subwoofers
    I have this DIY sealed 4cf TC2000 subwoofer that is up for sale. The box was my first DIY attempt and although it is sonically perfect it is not cosmetically perfect so keep that in mind. This is a sub only and has no amp. I am selling it so I can upgrade to a DTS-10 Danley and I need a few more...

    Sealed Subwoofer Build Projects
    And with these photos I officially start my build thread! You really don't understand how big this woofer is, till you see it in person. It's so big, it's almost perverted. :bigsmile: I've got two other projects going on right now, I'm going to push one off, but I have to finish the...

  18. IYHO - What commercial subs would compare to 125L sealed Maelstrom-X ?

    DIY Subwoofers - General Discussion
    I know this probably can't be answered definitively but subjectively what commercial subs would you say compare to a sealed Maelstrom-X in a 125L internal enclosure powered by Quest 3004 (just happens to be my future subs :P )? Lets take another sealed 18" for example... Velodyne DD18. Aside...

    DIY Subwoofers - General Discussion
    Hi Guys, Ill admit to knowing jack about designing subs (or just about anything audio related), so sorry if this is a dumb question. Basically I'd like to target around 120L internal volume, but would like a small footprint. Im not to worried about the height of the sub. With regards to...
