efficiant speaker with good bass?


I am looking for a pair of easy to drive speakers that have excellent bass response for rock music as well as good imaging. At the moment I have a pair of B&W CDM-1 NT's driven by a McIntosh 6450 integrated. I need a little more punch than what I have right now. I have had 2CE's, VR4jr's, Tylers, Meadowlarks & Triangles. I loved the VR4's the most & felt the Triangles had a simular sound to the B&W's but lacked the bass.
I need to stay around $1500 used & eventually want to try some of the low cost tubed integrateds in the 40-60 wpc range hence the reason for higher efficiancy speakers. I also want to switch back to a tower speaker.

I would like to try a pair but I haven't seen a pair used for $1500.00 either. I am sure I will find something, I am still looking at the options.
Fishwater - If you live in New York or New Jersey area, this can be arranged.
Mrjstark, I have been back home to NY the past three weekends in a row, I am in NH.
I can make an arrangements but you would have to let me know a couple days in advance if you decide to do so. Gay live in Jersey about 20 min. from Manhattan. He also knows owners of Zu speakers very well ( he was working with them on the room during HE Show in N.Y this year ). It's very, very possible that if you decide to go with Zu ( anyone - from the Zu line speakers ) he could give you a nice deal. Next week I'm going to Florida for 8 days.
You can email me at www.mrjstark@msn.com if you want to make the arrangements & contact info.
