Passive radiator

How about the Sunfire subs?

Arnettepartners-

my fave and reference speaker is the Thiel CS 2.4 or CS 2.7 models. This company still uses a passive radiator in all of its glory. For their particular designs, it works very well. Bass response and frequency range is simply, outstanding. For those whom have a listening space like, 20x20, 25x25 or 30x30...the CS 3.7 is a no-brainer.

Find a local dealer/retailer near you and get yourself a demo. It will perhaps change your view on the Passive radiator. Keep me posted & Happy listening.

My Def Tech Super Cube Reference sub uses two passive radiators in one box to outstanding effect.Tight and musical to the nines...

My only experience with a passive radiator was the original Vandersteen model 2 which I owned between 1986 to 1994. I never heard this design as a failure.

In the late 70's, at Tech Hifi, among all the major speaker brands and models sold that I heard, my overall favorite for a somewhat larger room were the OHM Hs, one of just a few, and the only OHM that used a passive radiator. They were the ones that did everything right. I think they went for $900 a pair or so back in 1978.

I did not have the right room or budget for those back then so I ended up with smaller ported Ls, which sounded similar on a smaller scale.

I came very close to going with new refurbed OHM Hs a couple years back when looking to bring my setup "up to date" based on the continued strong performance of my Ls, but decided to go with other models that can do the imaging and soundstage deal better than most box speakers from teh 70's.
