Soundstage and explosive dynamics?


I’m looking high and low for speakers with the following attributes:

1. Wide and deep soundstage. Speakers can disappear from the soundstage.
2. Decent imaging.
3. Explosive dynamics with force and surprise.
4. Costs less than $10k.

JBL Synthesis horn speakers with large woofers will give you a wide stage and fast bass. With that being said the listening room plays an important role. Demo what you can before making any big decisions. 
Maybe build the system from the bottom up, with multiple really powerful subwoofers (plus room equalization).
Try to find a pair of used pro studio main monitors. These are the big speakers that are often mounted in walls - Westlake, ATC, Genelec. Meyer etc.

What you are looking for may be a larger speaker rather than smaller.  

I am loving the dynamic shading I get from the Klipsch Cornwall speakers.  Very hard to beat for the money.
