No, swapping out will not make much difference. You will still have just one sub, with one set of lumpy bass modes. What will make a big difference is adding instead of swapping. More subs will be much better. Put them in different locations, both close to the walls but different distances from corners. Huge improvement.
Straight up comparison REL T7 subwoofer vs Sunfire SDS 12 woofer. Preferences or opinions?
I already own the Sunfire. I've got a solid bargain on the REL T7 and have verified it works fine.
The other gear is a B&K Pro-10 Sonata preamp, a matching B&K ST 202+ Sonata amplifier, OPPO BDP-105 Blu-ray player for source material and Monitor Audio Silver RX8 speakers. Room is 20x20x13. Is swapping my Sunfire out for the REL really going to make that much difference?
Thanks!
