15" ported sub

hola gentlemen!
One more marble sub appeared. not total marble, but top part is enough for make it substantial and it shouldn't jumping through the room.
I choose Pro-audio 15" woofer, made in according of my request, couse I don't like long-stroke things.
it will be able to take 1kW RMS, but for home use 200W is enough.
Cats, women and neighbors approved that audio equipment. now I even able to tell bass gitar from contrabass and will consider about OB loudspeaker, couse 3 way isn't necessary for that sub.
PS: I don't see pictures attached, ok, those who so desire can find it there
