    If the GRS T/S parms are accurate, and you're okay w/40Hz (should be fine for music) they should do well enough. Dayton's 8" "Classic" could go deeper in the same size box, but these should be able to play a LOT louder.

    The datasheet grossly overstates calculated Xmax by using an unusual and unconventional formula buried in a footnote.

    It's rare when multiple subs aren't better than one. It's even more rare when subs work as well beneath the mains as they do when placed where they work best. Keep that in mind before deciding on anything.

    Thanks for the info. I may look into multiple subs instead.

    Although more midbass is what i'm looking for. Maybe I need to take some room measurements before deciding what to do.

    Very nice for a compact bass guitar amp or a mid-bass. Doesn't interest me at all as a sub though.

    It can realize a 36Hz F3, but that's in a 2 cu ft net box. If I was using a box that big it would be loaded with a ten or twelve, probably sealed. The sensitivity is pretty good, but where low end output is concerned there's no replacement for displacement. With Vd of only 138cc it's just not there.

    With an Xmax of 6.5mm you won't get pounding deep bass, but the price is right for an economy setup. The frequency response gets goofy above 300Hz, but that's not a big deal for a sub. Qts of 0.55 means you'll have a tough time getting real flat response in a vented box, but once again that may not matter for an economy sub.

    Would these work well as a "musical sub"? The 8 inch has F3 of about 41 in a 1.3 FT3 vented box. They are very sensitive so maybe I could use 2 to support bookshelf speakers.
