TC Electronic additional RS cabinet advice
 

Ok so I'm running an rh450 with an rs212 and am thinking about buying another rs cab to link. Any recommendations on another 212 or a 210 (both rs)? Pros/cons?

If you already have the 212, go with a second one. You already know you like the 212, so doubling up is more of what you like. Adding a different cab can be unpredictable.

Stack the cabs vertically for better dispersion and to get the drivers closer to your ear.

If that still isnt enough, I think you can add a thrid RS212 for a killer big rig.

I'm using a RS 210 with my RS 212. It adds some clarity and mids that the 212 lacks. On its own, the 212 is a little dark sounding to my ear. The 210 brightens and tightens up the sound.

A lot of people dig this combination. Same manufacturer and design, and they tout them as a combination. From that perspective, I think it's safe enough to consider. I had it at one point, but my ear isn't discerning to get into to much of the nuance. With a grain of salt...I thought the basic character of the cabinets was very similar inside the margins, with the 212 being a little smoother and fatter. The 212 is obviously more capable volume-wise.

One pro is that with the RS210/RS212 stack, you have a modular thing going, where you have three options instead of two. The 210 is a little easier to get around, and if you have instances where it'll get the job done by itself, you have the option.

Thanks so much for the information everyone! I've played everything under the sun but TC Electronic has blown me away!
