I bet there are a few brand new speakers at street prices that offer better bang for the buck.
Besides Arendal (1” tweeter, 5” mid, 8” woofer x 4), another example is the RBH SFTR tower with 5” tweeter, dual 8” Midrange, dual 12” woofers) for under $10K/pair.
The RBH SVT towers (5” tweeter, three 8” Mids, dual 12” woofers) for under $12K/pair.
