Inflation! I ‘member buying a pair of these for $100 shipped each. Or maybe it was $80per, and the 15” versions were $100 per. I upgraded to the 15s later but I did not like them better. May have been the speakers paired or room. The pair of 12s (L+R) were used with Behringer/clone studio monitors (8” woofer) and sounded great as a whole. The pair of 15s (L+R) were used with Behringer PA speakers (15” woofers and compression horns). The 15 subs sounded a bit boomy and the plate amps were noisy (they were ab instead of d like in 12”). I checked for ground loop issue but the amps just hissed in the 15. The monitors sounded better for music. I tried the PA speakers for home theater but did not like them better for music. I tried multiple placements and crossover points with the 15s but could never get to sound as tight as 12” sub. Much variables... fyi tge speakers were crossed over - not run full range. I took measurements with minidsp mic for these setups but are on an old hard drive somewhere. All in-room though so not so helpful for anyone else.
