Buyout PR Subwoofer Project...

[tomzarbo]

That Summer Winds project looks amazing!

I agree my box is too small, I was trying to match the recommended size on the Peerless specs. I'm all for rebuilding a new box. I have another thread where it was suggested that I would likely be better off using the Tang Band W5 5 1/4" in a larger enclosure. I'm leaning towards a passive radiator design similar to what you've built in this thread using that W5 driver.

Would you be able to recommend which PR's would be a good match for the Tang Band W5-1138SMF 5-1/4" and a box volume? I'm using the Lepai LP210PA amp if that helps.

Boy, can I. This one: Peerless by Tymphany SDS-P830880 5 1/4" Passive Radiator.

Here is the link to Wolf's 'Triumph' page on photobucket. He has enough info there to explain it all. http://photobucket.com/gallery/user/...Dg4MQ==/?ref=1

That PR looks to be for sale on PE's site now, but you apparently have to buy a quantity? If you do a search for it, you'll find it at another vendor online for the "Mad" price of $11 if PE won't sell you two.

It's probably 'THE' small passive radiator'd subwoofer. I've built several and they are basically awesome.
Actually, it's the smaller, 'comparison' subwoofer in this post; here's a direct link to make life easy: http://techtalk.parts-express.com/fo...63#post1285563

It's a great little subwoofer, you'll love it.

P.S. Thanks for the kind words on the 'Summer Winds' project.

Thanks Tom! The Photobucket link is great! I did find the PR's, thanks! I definitely love the size factor of this. Appreciate all the info!

If I understand the Triumph design correctly that is using the Neo magnet of the W5, how would I determine how much to increase the box dimensions to accommodate the larger magnet on the ferrite version?

I assume it's just the difference between the volume displacement of each of the magnets but I don't see where I can get those dimensions.

Hopefully wolf sees this thread for official word, but the triumphs I built were the same size as outlined by him, and they use the ferrite version. Seems to work fine. I think others have done so as well.

I don't know that I'd worry about the difference since Tom has built with the ferrite and been happy.

Thanks for the referral, Tom! I still have one of the 2 I built back in 2007, not sure I'm going to give it up...

Later,
Wolf

Thank you! Just ordered what I needed!

Here’s a quick render from SketchUp of the build using 3/4” MDF. I saw someone else made a down firing version on this which looked amazing. Would anyone anticipate there being any drawbacks to that design?

As long as you can run a brace from top to bottom panels (I used a 1" dowel), then you won't sacrifice the integrity of the enclosure as I built it. The panels are not very large to start with, but bracing can still be important. With the woofer on the bottom, the brace would not be possible.
