Vandersteen Treo vs 3A Sig as upgrade

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.

Yes. It was Stereo Unlimited. Don't get me wrong, Bruce has one of the finest stores I've seen/heard along with the incredible Vandersteen 7's. Maybe there was something with the Quatro's setup that wasn't quite right. Who knows? I do agree that two subs would be better than one, but now that I'm retired, I will have to be satisfied with one sub, at least for awhile as disposable income is at a bit of a premium for me right now. But I WILL own two in the not so distant future. Bruce thought I could get by with the less expensive X-2 crossovers instead of the premium crossovers with the batteries. He felt there wasn't much difference in the overall sound compared to the cheaper X-2's. Richard Vandersteen says differently....Hmmm....decisions, decisions.

@mr_m If you do go with the X-2 at first, do you know what impedance you would need based on your power amp?
