I've been considering adding a subwoofer with my 8351b's and I would like to stick with Genelec subwoofers in order to use GLM. In the US I can get 2 8 inch 7350 SAM subs for $1260 per sub or 1 10 inch 7360 for $2560. The 7350 goes to 22hz the 7360 to 19hz. I've never tried to incorporate a subwoofer which is why I would like to stay with GLM. My question is which way would give the best result, my gut feeling is 2 of the 7350 but maybe my gut is wrong and 1 of the 7360 would work better. This is only for a 2.1 or 2.2 system not a HT setup. I couldn't find a subwoofer thread so I hope this is the right sub forum. Thanks for any input.
