Stillpoints Under Speakers

@acresverde  Superb post. Have you considered a custom solution from Star Sound Technologies? Might be worth the phone call. Perhaps they can provide that elusive 'best of both worlds' solution?

Cheers, - David.

Very helpful--thanks everyone who has posted so far. @acresverde am I understanding correctly that you only used the Stillpoint Ultra/Base with your subs? Just trying to see whether your results are transferable to my situation since I'll be using them on full range floorstanders.
Please keep the comments coming!

Hi DA,

I guess because they've been around for so long I thought that the average audiophile would be familiar with the architecture of the AG Duos. In a nutshell, the Duo consists of (bottom to top) an MDF sub cabinet (sealed) with two 10" drivers, then the tweeter horn, then topping out with the midrange horn. All three assemblies are bracketed in between three vertical metal support rods (two on the outside edge and one on the inside edge of the assemblies) with the support rods being threaded at the bottom so as to receive footers. The Stillpoints are, therefore, screwed into the bottom of the support rods and all of the assemblies are being held up by them. I should note, however, that the underside of the sub cabinets themselves do have four threaded inserts to allow the user to choose to support the entire speaker assembly by screwing footers into those inserts rather than the bottom of the support tubes. And, in fact, when I was employing the Mapleshades, that was the route I took.  With the Stillpoints I chose to use the support rods for mounting.

If this description is still a little blurry for you, just google AG Duo and you'll get all the images you need to clarify it.
