I’ve been happy for about 5 yrs with my stand-mount speakers that go down to 41hz.
(Current setup: Cambridge Audio SX-60, S.M.S.L. AD18)
But film soundtracks drop lower than 41hz fairly often and I want to take advantage of the lossless audio in my blu-ray collection. Some movies use the LFE channel extensively. I can’t put in surround sound due to the lousy layout of my apartment, so this is the best I can do to improve my film sound at this point.
The good news is that companies like SVS give you a trial period so if I determine that the sub is not making enough of a difference to justify the cost I could return it.
I’ve also been kicking around the idea of upgrading from the Class D SMSL AD18 which maxes out at 50wpc to a class AB amplifier that does 100wpc or better.
There was no big point to all this chatter, I just like talking about it
