    Hi everyone i have been wanting to do a subwoofer diy build so i have found a Dayton Audio RSS315HO-4 and they have enclosures for them but they are sealed i i'm not a fan of sealed subwoofers but i have found that doing this subwoofer would be hard to do it as ported because of how long the...

    I have always loved passive radiators, so I thought I would finally do a build log along with all the parts needed. Thanks to Parts Express, I am able to bring one of these Passive Radiator Builds to life. My goal was to make a small subwoofer that would still have high spl, for a smaller room...

    This is my first time posting, although I've been a long time reader of the forums. I am rebuilding this sub in a new enclosure, with a new amp, since I did such a cheapo job last time I built it. I had basically just thrown it in an old Velodyne enclosure that was made for an 8 inch sub with...

    Hello everybody, I am curious about passive radiators and would love to try a build sometime. I modeled a SI 18 with two PSI passives in 10 CUFT feet. My question is the PSI site lists two values for xmax, 65 mm and 32 mm total, which one should I use to model? I have attached a WinISD file...

    I finally started the project. Originally I was looking for a high quality sub amp. This lead me to Funk Audio. Nathan and I discussed my goals for my home theater system and after many e-mails I finally settled on the system I'm currently building. Amplifier: Funk Audio 2.4kw x 2 version 1...

    Question. What are the choices that I have with passive radiators and a tc sounds lms ultra 5400? I would like to use 2 but the price for tc sounds passive radiators are very expensive. I was looking at psi car audio and the usable xmax is 3.5 in. Would 2 be close to over excursion if used...

    Hello all, I got an idea that might get me lower tuining with this subwoofer as I am not happy at the moment and cant afford getting the tc 5400 up and running yet. Its a mtx sw1515 and it does not like deep output and seems to have a steep roll off at around 30hz. Anyone have an idea how I...

    Hey I'm looking into building 2 passive radiator type subs. I've only ever delt with llt's before and don't really know anything about passive slap designs. I have to get the drivers and passive's of the site solen.ca. I'm thinking of going with dayton Rf hf and the dayton passive's. I have a...

    Please help me design a passive radiator enclosure for my 2 Cerwin Vega VMAX15.2 drivers. Power is coming from a pair of BASH 500 plate amps and signal will be optimized by Audyssey in a receiver or separates yet to be purchased. I'm not fond of sealed boxes but last time I attempted to spec a...

    I've been playing with building out a home entertainment center with shelfing to replace my stand alone equipment stand and stand alone sealed subwoofer enclosure. While doing this, I have the opportunity to modify my enclosure design some and was looking at doing a PR build. To do this build...

    I read with great interest this old post: http://www.hometheatershack.com/forums/diy-subwoofers-general-discussion/44315-tc-sounds-epic-8-builds.html I must say that I would like to make it as a subwoofer pc and I also saw these passive 8 of dayton audio...

    going to be building some l/r tower speakers and im not sure where the best placement for the PR should be. will it be better on the side or on the back, in the same plane as the driver or at the bottom? 1will be using a DD6.5LT driver and a Dayton 8" PR with about a 1 cubic feet cavity. would...

    Seems my AE AH15-h subwoofer is voice coil rubbing and need a 15" replacement. Need ones that model well with 2 15" pr's that can handle 1050-1800 grams in a 3 cube box. I can add stuffing and make it roughly 3.5-4. PR's: AE 25" 1050 model. Power: Bash 500 watt Would like posts of subs...

    if i had a "blown" sub or a fully assembled sub an put it in a enclosure an not hook it up as a working woofer and use the other woofers in the enclosure as amplified woofer an keep the one woofer unhooked up will it work as a PR? understable that the enclosure could not be tuned will it work...

    I guess it was only a matter of time till I dabbled with pr's, so this one should be interesting. This will be built around an Fi Q18 and use a pair of 18" AE 2100 pr's. The cabinet will be around 180 litres which should yield a tune of about 18hz. The plan is a forward firing driver with dual...

    hey all! Here's my story: Been running a pair of sealed 13AV2 d4's in 2.3 cf boxes, powered by a Face Audio F700 (claimed 1100 watts/channel into 2 ohm) for about a year in my 2000 cubic foot theater. Response is flat down to about 15hz, where i have a high-pass filter running since these things...
  18. Ported Subwoofer Build Projects
    Ive played with sealed and ported designs so decided to get stuck into a pr design. The design needs to be kept fairly compact considering we are using an 18" driver, so pr's seem to make sense. The design will use an Fi 18" Q series driver with 500 watts input, and 2 AE 2100 pr's. The cabinet...

    "Long time listener first time caller" :) Hi all, I really hope you guys can point me in the right direction. For some time now I have been modeling various configurations in WinISD and just can't get the feel for all the variables involved with PRs. All kinds of ported models work out just...

    I built a 24" sealed Mal-X, Gen II sub last summer. It sounds outstanding, but now I am unhappy with my main speakers (Paradigm 9seMkIII's). I thought about using my Magnepan MMG's for HT duty, but decided to build some L/C/R's instead. Current plan is to build waveguide speakers that are...
