Well, we all have our perspectives, huh?
I'd call the Genelec subs
little, cute, and
very dang expensive.
(I'm setting aside heavy, because optimally designed subs will always be as heavy for their size, as one can tolerate.)
Subs more to my (DIY) tastes...

Stack of single 18" sealed, or double 18" vented.
View attachment 539135
Cost of 4 sub sealed stack: $2500. Cost of double 18" vented $1250.
Amps and processor for stereo pair of either: $2500.
I use stereo subs, so a total of either $7500 or $5000. (yes, it takes four sealed single 18" subs to equal one double 18" vented).....
.....vs a single mono-use, top of line Genelec 7382A 3 x 15" at $16,000 (Sweetwater)
I've got more SPL; probably equal or lower distortion at same SPLs; more amplifier power and far greater DSP capability (using live-sound amps and an install-sound open-architecture processor).
Also have ...as I'm sure most of you guys see it.... mo' bigger, and mo' ugly...lol
To each our own, huh?
