Anyone know any good in room passive subs? Only need to go down to 40 or so before rolling off so can be small. I have the Procella option but they are pricey...

Not a big market, since much of the point of a dedicated sub is so that the system's amplifiers don't have to handle the prodigious power required for low bass. Even those Procella subs come in versions without amps only because they expect you to dedicate an amp in your rack to them.

Why would a powered sub not work for you?

Wiring logistics. It's a retrofit job and there is no power where I want to put the subs, but running low voltage (speaker wire) will be easy.

Hmm. Velodyne "SubContractor" series, maybe?

There are a lot of passive subs in the pro-audio industry, of course, and also for car audio. Probably not what you want if it'll be exposed, however.

You could try a Blackbird or Raptor system from Dave at bossobass.com. He goes by bossobass here on the forum. Jeff (JTR Speakers) or Mark (Seaton Sound) could probably provide you with a passive sub. They use amps from Speaker Power and maybe they could use a rack mount DSP amp from Speaker Power instead of the plate amp. If you only want down to 40 Hz, the JTR Growler is ideal and it is passive. Although it isn't shown on the website, I think you can get them custom with veneers for a more upscale look. Danley Sound Labs has some passive subs, but they are probably larger than what you are looking for.

If the amp just needs to be remote, there are a variety of options from Velodyne and Triad. If you need something more ambitious, drop me a line as desertdome suggested.
