Hi,
I have a pair of 8" monitors that I use for entertainment. Movies, games and music.
The bass seems fine for music, but it doesn't go low enough for movies and games. I think they get as low as 40hz or so.
I understand that you cannot bypass the subwoofer once it's hooked up, so it's important that it won't suck for music.
Options:
A new BIC F12, Dayton 1200/1500, and others up to $250 (used on Amazon is fine, too).
Or any of these used that are sold locally:
Tannoy TS-10
Klipsch R-12SW
JMLAB SW700
Mission M70as
Tannoy Saturn S-SUB 15
Yamaha YST-SW300
Mordaunt Short MS907W
Velodyne VA 68X2E
The Tannoy TS-10 has gotten a very good review from What Hi-Fi, if it means anything.
It is said to be musical, if that's a thing in subwoofers.
The Klipsch R-12SW has a better amplifier, but I couldn't find any "professional" reviews.
The others on the list are significantly older and there's not much about them on the web.
I guess the main contenders are the first 3 options I listed.
I'd appreciate your input.
