muypogi,
Good day!
Sir, we do sealed type subwoofer for only 5k 8" driver 150 watts.
Kaya ba yung 5k sealed sub with these specs:
1) 8 inch sub, either the Tang Band W8-740P or the W8-1363SB
2) speaker-level inputs, since I have a tube amp and I don't have a sub out
3) 150-200w amp with variable x-over and level, possibly with phase switch
Thanks!
