In all my research over time I have mostly been looking for Driver chassis which are distinctively different and suited in correspondence to some of my own enclosure ideas. The two driver chassis I became extremely interested in, and these I found only a few weeks ago were the ‘Tang Band W8-740P...

Hi, I built a sealed box (~100 l] for my LMS Ultra about a year ago. I recently bought 2 TC Sounds VMP 18 passive radiators and now I'm thinking my next build. Should I use both PRs for the LMS Ultra or is one sufficient? I'm planning on buying one more LMS Ultra when one is available (they...

Hi I've a sealed CSS SDX10 sub that i'm quite happy with for the past year and odd. Recently i had a chance to buy a pair of AE 12" PR (PR12-970), and wish to use it with the existing SDX10. I have never used winisd to model a PR design and was wondering if someone could help me out here. Just...

Hey guys. This is a shot in the dark but does anyone know how to mount psi car audio 18" passive radiators? The reason I ask is because the rubber gasket that is used has mounting holes that are smaller then the holes in the actual basket assembly. I feel that there should be an insert of some...

Purchased a JL 13w7 for a new project. Been searching the forums and haven't seen to many diy builds with them so figured I'd reach out and look for some input. Thoughts are to go dual PR's. Did some modeling and was looking at 3.8 net running 2x15" PR weighted 1400grs. Power would be supplied...

This is the best PR I've found: http://meniscusaudio.com/css-apr12-p-965.html To go with this sub: http://www.parts-express.com/dayton-audio-rss315hfa-8-12-reference-hf-subwoofer-8-ohm--295-445 Can you suggest another? Thanks!

I'm looking into building multiple small subs for my basement living room. I was really impressed with the performance of 4 REL T-9's and a friends house. The T-9 uses a 10" sub w/ a 10" passive radiator 300w plate amp and is (W x H x D):13 x 14.75 x 14.75 in. I am looking for ideas on something...

Hi Shack members.. I have decided to take on a 12” SDX PR build and thought I would share it over here at the Shack. It’s a design I never have built before or listened to for that matter, so I’m keeping my fingers crossed and hoping for the best. I’m going with the 12” SDX dual PR build because...

Have you considered using 1 or 2 TC Passive Radiators in your design...some of the reviews of PR's are very promising... I will be building my new TC sub with this combo and will probably use the Crown XTi 4002 XTi 2 Series Power Amplifier as it has the power range I want and the sub harmonic...

Looking for a pair of 12" or 15" PR's. please contact me if you have a pair your looking to get rid of.

Working on designing another enclosure which will consist of dual 12" subs and dual PR's. after a lot of modeling I'm showing a really flat response from around 20hz to 32hz. Not having really worked with having to fix a response like this what suggestion would you have the response is low about...

I recently aquired a 10" Dayton rss265hf-4 and was considering buying two sd270-prs and building a sub for home theater. I have read lots of previous peoples builds with the sdx (mikep's) build and was wondering if the similar enclosure size would work the room is 14x20x8 open one side and would...

I've got my system in a room that measures 5x7 metres and I'm still tossing up what sub design is best and most value for money. Priority is for music as the floorstanders I want to match with are good music ones, but I'd still like to be able to hit the low 20 Hz level to get that "Wow!"...

Hi Folks, I have a Shiva-X sitting around that I would like to put in use. I really like the size/waf of a fellow member here who did a 3-3.5 cuft build w/ a single Shiva-x and 2x15" PR's. Now that Exodus Audio (or whatever the company was in WA) is out of business where can I get the 15" PR's...

Hi does anyone know if these units came with an inbuilt high pass filter and if so what is the frequency they set the cut off at? I am building a Passive radiator based on Adrian Macks 12"XLS peerless design. I have the peerless driver but substituted the Peerless Passives with 2 12"...

So here is the stuff I have for the build: 2 QSC PLX 3402 2 Exodus Mal-X 18" 4 Exodus 18" Passive Radiators (washers for 1625g each with bolts for tune) BFD Reckhorn B2 1 Crown K2 (currently driving 2 12" cheapo subs I have now) I bought this all a while ago and then wired a new 20A circuit so...

I purchased an occam audio SDX 10 downfiring sub about a month ago. The dimension are 12.5 x 14 x 16. The port length is 12 inches. I replaced the straight port with a flared precision port keeping the 12 inch length and had an issue with the amp not getting signal after reinstalling. Madisound...

How do you model a passive radiator in winisd?

Hi guys, first post here, so a bit about me first! I built a HTPC a couple of years ago and have been hooked on DIY AV stuff ever since, since its been a massive success with the WAF sky high. :clap:Documented my journey from AV noob to someone who knows a bit more than average on a blog...
