Vandersteen 2WQ vs Martin Logan Depth

Thank you for your response, Macdadtexas. I am looking for a subwoofer that is great for music in my 2- channel setup. The Velodyne DD-15 is out of my budget. I will check the JL subs as per your recommendation.

More suggestions welcome, Audiogoners.

Since you've asked for more suggestions ... I've not heard the 2WQs but have heard the ML Depth when I was evaluating subs for my 2-channel music system. I found the ACI Titan XL more musically satisfying than the ML (or others I heard including REL, B&W, Klipsch, etc.) I played bass heavy music with mains off for evaluation. The Titan sounded most musical to my ears.

The 2Wq is a different breed of animal in that it hooks quite differently than other subs. It hooks to the outputs of your amp and tracks the signature of it. The amp is receiving a rolled off input from the included x-over. Your amp is only producing a musical signal that rolls off the lows below 100 hz. This allows your amp to work much more efficiently and sound better. The full description can be found on the Vandersteen website. I have found that the 2Wq integrates quite seemlessly into my system. More so than anything else I've listened to. You really don't even know it is there until you play something with incredibly deep bass and by then the walls will be rattling!

I just added a single 2Wq to my Vandy 3A Sig's yesterday and WOW what a difference. I have to agree with Donwass65 they don't contribute that much to the sound until you get something with low information. It fills in a lot of information to a double bass, I also noticed that it really helps to bring out the reverberation of the venue in which the recording was made. This could be from the cleaner information coming from the mains I'm not sure but one thing for certain if you get the 2Wq make sure you get the X-5 crossovers (the one for the Quattro and the 5A's) they make a huge difference in the sound that comes from your mains. I tried both yesterday and the X-5 is a lot more transparent than the the WX-2

lg316b, are you considering a 2nd 2wq? It gets better still - not more "bass", but even better soundstaging and midrange clarity. The 3As with 2wqs were the best integrated mains/subs I have heard - usually I am quite disappointed in subwoofer integration but Vandersteen has seemed to work it out, at least with his speakers.
