I need some speaker help

I'm willing to spend the money for the right set of speakers that will hold up to Joe Bonamassa crankin'.

You need clean amplification and spreakers with pro drivers (not consumer speakers with northern european mass produced drivers). Horns with TAD drivers and woofers or ATC or PMC or Meyer or Westlake speakers.

It is not well known (as there are no specifications for it) but consumer speakers will compress relatively quickly (Xmax and thermal compression limits how loud they can play). A typical pro driver will typically play 6 db louder than the very best Excel consumer woofers without any hint of compression. Once you have a design with all pro drivers then it boils down to just a BIGGER BOX and more large woofers to get you were in SPL you want to go. (Note that because consumer designs are not intended to play loud then the tweeter and mid range are usually not capable of going loud either - so it is NOT as simple as adding several JL F113 subs as you will still get compression and faliure from tweeters and midrange. A pro design will use a waveguide to assist the tweeter down low and it will tend to crossover the tweeter higher in frequency so as to limit its excursion when playing loud)

I saw Joe Bonnamassa wednesday and he was great but extremely loud.

Mr S- I've been in the sound reinforcement business for almost 30 years and never has seen a speaker system or horn design that varies it's tweeter's response with relation to it's SPL. What company or companies build such a system or crossover? I'm assuming it would also have to vary the midrange so as not to leave a gap in the system's response as it's output increased? I'm truly intrigued. You use the term "waveguide" which is a horn/throat design intended to smooth the frequency response of a horn across it's entire dispersion range, and has nothing at all to do with the driver's crossover frequency or it's diaphragm's excursion.
