Vandersteen Treo vs 3A Sig as upgrade

@mr_m great post above. I also have Treo CT.  I have two 2wq subwoofers and agree completely with what you said referencing dynamic life and the opening up of the soundstage with the quality deep bass from the subs.  

Interestingly if you read the online magazine "Copper" located at the PS Audio website, their latest issue, #14 has an article about what subwoofers can do for a system.  You are echoing a good bit of what he said.

Enjoy the music!

You guys are killing me.  Subs or Quatros......Quatros or subs......time for a wee gargle o' Islay.

@ hifiman5, I just started the article in "Copper", it is the first in a series of articles re Subs
@ mr.m  I am in Tucson where in AZ are you located?

Thanks for the compliment hifiman. This wasn't the first time I heard the qualities while using a sub. I heard a pair of Wilsons with their Thor's Hammer sub with similar results. Although I thought the Vandersteen combo actually sounded better for a lot less money! I will check out the online magazine "Copper" at the PS Audio website. thanks for the "heads up" on that. Question for Ctsooner. Do you need the Vandersteen filters for the Quatro Wood Ct like you do for the 2Wq subs????

Are you talking about the crossovers?  Yes, adding subs you will only run your main amp from 100hz on up so it frees it up to sound better.  Richard has shared that in order to integrate a sub, you need a full range speaker with a one octave cross over in order to do it right.  At least right for what he professes.  The way he does his subs is that the amp mimics the main amp you are using, so that's why it will sound better than any other brand with Vandersteens.

I wasn't saying the Treo CT with one sub wouldn't sound great, just that personally I feel it needs both. I've heard them that way a few times now and it makes a huge difference, but to me I still fee Quatro's are better when set up properly.  Was it at Stereo Unlimited in SD?  I bought a ton of stuff from Bruce back in the early 80's when I was stationed out there.  It's a great store if that's where you were.

No grain of salt at all.  When I read stuff that I don't fully agree with I always try to go listen to what they are talking about.  It's not easy, but I try unless it's outlandish to me, lol.  

It's all good man.  We all love listening to MUSIC and not the components.
