Besides SVS? I do not think I have ever seen one other mentioned on here. Did I miss something?

I think Elemental Designs has one/will have one. Check this blog entry (http://blog.edesignaudio.com/?p=308) and their store page (http://www.edesignaudio.com/product_info.php?t=1&products_id=682) for it. Looks to be a hefty price tag for them, though :(

The elemental designs isn't a cylinder though. it's a tall tower made from MDF. Most cylinders are cardboard. Although that sounds cheesy, it's very strong and the design of a cylinder doesn't flex like a flat surface might.

Dana audio used to make a cylinder sub (1990's). today, i think SVS is the sole manufacturer. There's a lot of DIY cylinders also.

We sold cylindrical subwoofers from 1991 until early 2005. We plan to reintroduce the TN1220HO cylinder subwoofer at some point next year.

Funky Waves also makes a Cylinder.
She's a big on too....

Nathan Funk does all kinds of cool stuff. I started to set up the D-cross section mains cabinets he built for me (to hold the 12" Dual Concentrics out of a set of Tannoy System 12 DMT II's) today. (Pics coming when I find the Sd card I thought was in my camera.)

I wonder why cylinder subs died. They make so much sense to ship around, because they're so much lighter than wood boxes. Shipping size restrictions, perhaps?

I'd love to see a well-designed commercial bandpass cylinder sub. That would be a great supplemental above-the-room-centerline sub for an awful lot of systems.

Heh...:D Thats mine. It sounds as good as it looks too. Just listened to it a bit last night watching The Departed. Believe it or not that thing is not light by any means. Trust me. I had to carry it up a flight and a half of steps!


DS-21,

I want pics! :)

I have one of these and in my 1600 cubic foot room its a BEAST. But tucked into the corner in the shadows its nearly invisible to the eye (at least as invisible as a black tube that comes up to my chin level can be. I'm going to get some pics and review up soon. hey also make smaller versions with a 12 inch driver.

We sold cylindrical subwoofers from 1991 until early 2005. We plan to reintroduce the TN1220HO cylinder subwoofer at some point next year.

Hopefully with the 15 inch driver ;)
