Best High Efficiency Speakers for full bass tone

["Looking for something with better bass detail than a pair of extra subs rumbling 60 hz and under."]

I have a pair of Velodyne DD12+ that are extremely detailed, in fact I can't even tell if they're turned on until I turn them off. Or, with the push of a button on their remote, they can thump a kick drum to live levels and beyond all the live long day.

I'm guessing you need to hear a modern subwoofer system properly set up. But hey, good luck with your search.

I have a lot of speakers as I am somewhat of a collector. Currently have Klipschorns, Jbl L200's, Altec VOTT, JBL L220's and as good as they are none comes close to the quality and quanity of bass that my Westminster Royals have. They are very expensive and should give something special at the price. Well they do, top to bottom the most pleasing speakers I have ever owned.

I've heard the large Classic Audio Reproductions models that I belive are fairly Hi Eff and seem to do it all very well. Similar in size, cost and retro styling to the large Tannoys.

I have heard Cathedral speakers at a few Capital Audiofests. I could easily live with and even afford those I think.

Altec Valencias would be great with vintage equpmt in a room that size and not break the bank.
