Used monitor under$600 with good bass low levels

I plan on consulting with Meniscus, they have been in the business for a long time. I will let them help choose the drivers and design the cross-over and other parts.

Now you are talking - glad to hear you are getting some help - this is no easy slam dunk - for sure!

Shadorne,
I should have mentioned it earlier I thought others realised I am prudent in my efforts and take the smarter route. But then looking at my tt I wonder what others think?
I assure you the suspension works, at the tt and the speakers.
I believe speaker companies should take that route in designing. Imagine every house has a different type of floor, some concrete some wooden and all have different densities. If speakers were designed and played back suspended there would be a consistency that the designer will know will be heard through out. For the exotic boutique speakers I would like to see the optimal room size recognized and for those with the megabucks who buy this to build accordingly.

Shoot for a sat/sub system. Getting bass out of the main speaker is a real plus. Most of the real high end speakers are sat/sub! I have a pair of Warfdale Diamonds (biamp) that sound quite good with a powered sub
