Not sure if the OP just ordered the T9's or not but I have tried them all in pairs and I was shocked at how much more I preferred the T5's over any of them simply because of their active down-firing and for even less money than a single T9 you can have a pair of 5's. Regardless of the stats claims, I preferred the T5's because the down-firing was just more impactful and far more effortless while the others had to work harder to produce bass impact. I just could never feel the same bass with the others. For pipe organs I would not expect the T zeros to deliver. There doesn't seem to be mention of floor material. Since my floors are hardwood, they generate their own resonance in a good way so I went with the Tzeros instead of the T5's. Despite claims of 12" subs, they are too slow for great musicality and on the rare occasions of pipe organ they may deliver but for overall music, there's just no need for all that in my experiences with music. If people are into thunderous bass for movies and stuff, I get it but for pure musicality, forget it. We have the Magnepan 1.7i's and LRS plus.
Little help with REL subwoofers, please?
I'm not especially knowledgeable about subwoofers and I'd appreciate some advice. I've got a pair of Magnepan 1.7i placed in a small (long, rectangular) room. I had a hefty JL sub that shook the house but that I could never fully integrate. On a whim, I switched it out for a pair of the diminutive REL Tzero subs and the sound is vastly better. On some music, though, such as classical organ, I miss the growl and thunder. I don't feel like I need to boost the "upper bass" and I definitely don't want to muddy things up; it's really the deep rumble that I occasionally want.
If it helps, I'm thinking of a piece of music like Max Richter's "On the Nature of Daylight," which about halfway through delivers a broad, deep sweep of musical sound that I want to *feel.*
I'm mostly pleased with the setup and I don't want to reinvent my room's wheel or break the bank. And I'd like to stay with at least two subs and likely stay with REL. So I'm thinking I might: 1) add a T/9X or maybe a T/7X and perhaps keep the crossover low; or 2) swap out the Tzeros and replace them with a pair of T/7Xs. For now, a pair of T/9Xs is a budgetary stretch that I'd like to avoid (and it is a small room).
Would it be weird having two Tzeros combined with the much bigger T/9X? Would the T/7X produce that deep, enveloping bass? I'm not particularly good at reading specs but -6dB at 30Hz doesn't sound especially deep to me. (The JL was -3dB at 23Hz.) Or am I misunderstanding how bass works and would a T/7X go plenty deep in a small room?
Thanks and Happy New Year!
