I think is time for new speakers..

Silverline Minuet Supreme Plus would be a good choice.  Best of luck. 

Oldhvymec, as much I want to build another DIY speakers, I dont have the time.

Soix, I am looking for a balance sound without any fatigue during long listening sessions. I want a speaker that has articulate, define bass. Midrange should sound clear and not overwhelming. High should sound airy and detail and not foward. Im probably asking to much from such a budget but I know I can find it.

Yes agree with the Klipsch and Elac recommendations. 

Specifically the RP 600M and the Debut Reference.

What aspects of sound reproduction and speaker performance are most important to you?

check with GR Research. He bought a container of speakers and is selling them for a great price, though I don't recall if they are < $800

+1 Klipsch and ELAC

What about another set of DIY, you know what you built, that you're happy with now. What is it you want to change, or is it, just time for "A Change"?

OR

You can buy flat packs, with drivers and XOs. Probably wouldn't get an automotive finish, unless you can do the paint... GR, Madison, few others.

Klipsch RP600M or RP8000 

Thanks for all the response. I will keep in mind the suggestions on the speakers.

Jond, yes that what I want to do first before I give them away. Thanks

Some good recommendations above but you should wait to give your speakers away. For $800 even used dollars your DIY speakers may indeed sound better,  worth a listen at least.

These jump out at me, used. The Salks especially.
