Mirage M1 Speakers

He wants to isolate not couple, probably because he has a suspended floor.
And you really need to isolate from suspended floors with big bass speakers like these, otherwise if coupled, the floor becomes a "sound board" also and muddies the bass.

I'll forward the good advice to my friend. Thanks.

The stability provided by the Sound City outriggers and isolating the speakers from the floor are two separate (but admittedly related) issues. As I have said before about the Townshend Seismic Pods, they may be used in place of the spikes provided with outriggers, and to great benefit. A set of the Pods used with an outrigger-style base is a great combo. As good as the Townshend Speaker Podium? I don't know, but much cheaper!

The Townsend Isolation Bars look really good, but I don't think my friend wants to spend that much money. I'll check out the Sound City outriggers.Thanks.

Check out Herbie's Audio Lab threaded gliders. They would be in the similar price range to the Sound O' City outriggers. You just need to know the thread pitch of the inserts in the base of the M-1s. Great speakers by the way. They do like a lot of quality power and need some room around them as mentioned above.
