Should I try to improve speakers at $2000.00 range

You have a really nice system!

For $2k on the used market you can find a better speaker than the Celestion, but that doesn't mean you will like how those speakers sound any better than what you already got. My suggestion is you should upgrade the Celestion's crossovers. Replace the old parts with premium ones. It's a cheap upgrade with the potential for a big sonic payoff.

I agree with this as I have been through it. Kept trying speakers with better pedigrees, looked better on paper and had stellar reviews. But they never made me smile like the speakers I was attempting to replace.
If you go searching my advice is to keep the Celestions as a reference.

The SL-700s are still hard to beat. The crossover components can be updated but the fact remains that the aerolam enclosure is still state of the art and the drivers are very high quality.

A Silverline SR 17.5 would better or equal the SL-700 in every aspect.

I knew the Celestion 6's as great speakers, but did not and don't know the 700's. I own the Spendor SA1's and they are superb little speakers, sounding much bigger than their size would indicate.I formerly has the S3/5 and the "R" version. The SA1's are a major leap forward.Very sophisticated little devils. You should give them a listen.
