When you say multiple, you mean two right? And you went the other way back to one sub? Which one are you running?
You're the first person I've seen go back down in number. Did you do measurements? Did you treat your room?
I do get nice response from my current one sub setup. You can see where it is in the pic. I don't have any measurements but it blends very nicely. I can tell where it is though and it doesn't really fill the whole room at low volume. That's what I want. But at higher volume it crushes. I think it's tuned very low. Probably why it sounds so good. Feature wize, it's very basic. Still a very musical sub. I'll have fond memories using it, but its days are numbered. I've not really experienced many subs, so looking forward to exploring my options.
Anyone else wanna try and convince me one sub is better? That's a new one.
