Ohm delivered various great sounding box design speakers that used passive radiators like the H and CAM 42 models for many years. The H was top of the line box design and my favorite back in the day.
I have a pair of brand new Vanatoo Transparent 1 Encore speakers that leverage passive radiators among other technology tricks to get a lot of good bass out of a very small box and these sound amazing especially for the size.
I also have a Klipsch sw308 sub I use with KEF ls50s that uses a forward firing 8" main driver and two side firing (one each way) 8" passive radiators to deliver a lot of great bass again out of a smaller box. Love it!
So as you can tell I am a long time passive radiator fan. More speakers should use them.
