Subwoofer Choice


I am in the process of building out my system. I have the end goal in mind, and ticking off the equipment as I get them. I do need some advice in the subwoofer category.

I am currently driving Monitor Audio Silver 500s with a Michi X5 integrated amp (600w @ 4Ohms RMS). This is way overkill for these speakers. But my purchase (coming in August) will be the Focal Sopra No. 3s.

That being said, I am looking also to add a subwoofer and I’ve settled between two (2) REL T/9x’s or one (1) REL S/510. T/9X is $1,249 vs S/510 at $2,749.

There is a REL youtube video from their chief designer comparing (briefly) the two and actually stating that "just because one S/510 costs twice as much as 2 T/9x don’t think you can equate them with 2 vs 1". I paraphrased a bit.

But the below is only 3min long please watch and let me know!

What are your thoughts. Obviously 2 subs are better balanced than 1, I get that. But given the specs here am I better at buying up for the better 10"?

Listening room is carpet, 16’ x 24’. 384sqft. 8ft ceilings. What info did I leave out?

It looks like only the 1000 Pro series has speaker level inputs. The Michi has subwoofer outs for dual subs. Each output is mono with the left and right signal summed.

Yeah, I’m pretty sure the SB1000 is the only one that accepts speaker-level inputs (never really understood why that is), but I think you can only take advantage of the SVS integration software using line-level inputs so don’t discount that as it’s significant.

I’ve owned the T-Zero MK3, T/7, T/9X, the S510 and currently have a Carbon Special. I can tell you that there is a significant jump in performance between models. That being said, @lak is on point. Get one S510 now and add a 2nd later. They are fantastic subs!

I also have in SVS SB3000. I like that you can alter the impedance curve from your listening chair with an iPhone. I’ve got it to my preference!
