What Speaker are Great for Rock and Roll $5K-20K

B&W 801 Matrix is what I used before my N802's. Depending on price but for under $3K used or a pair of the Nautilus for double that with the right cables, you would be rocking. I had the optional North Creek crossovers with my Matrix which almost doubled their performance.

Dunlavy IV,IVa,V models are excellent choices.

Bugtussels bass is transmission line like the Shahinian. Could we have a connection here?

Just the name "Bugtussels" makes me want to own these.

Legacy Focus 20/20. (3) 12 inch woofers per speaker should 'Rock' his world.
