guys;
thanks for all the feedback. I think I rushed this review to go live before CES and decided to clarify my text on the issue of applying a limiter on a sub. IMO this should be done on a stand alone subwoofer product, but not necessarily on a full range speaker system.
Here is my rewrite of that paragraph:
In my huge room I initially was able to induce mechanical noise out of the subs at extreme output levels. At first listen, I thought I was bottoming the drivers but later discovered the leads on the woofers were slapping against the cone. I pushed the leads out on the problematic woofers and this virtually eliminated this phenomenon - reducing it to a slight buzz when I stuck my head next to the woofers while playing at insanely loud SPL levels (not recommended for health reasons). RBH informed me this is something they normally do with the bass drivers of every production unit before installing them into the cabinet.
The bass portion of the T-30LSE system is so phenomenal, that I’d hope for RBH to one day offer stand alone subwoofer version of this design. Mechanical noise at high output levels, especially with long throw drivers, is quite common with products that don’t employ any self limiting within the mating amplifier or electronics. Perhaps if RBH Sound introduces such a product (ie. 1010-SE/R) based on this design, they can integrate an amplifier best suited for the drivers that will work within their mechanical design constraints along with offering active equalization for the low frequency optimization. Many manufacturers are doing this in their subwoofer products and I believe it would be a huge value with a small price premium for customers wanting the ultimate “tweakability” from the product. I suspect the ultimate setup of a T-30LSE system in a large room like mine would be the compliment of two additional subwoofers matching the performance of these speakers. The fact that I can’t say that about too many full range loudspeakers, speaks volumes about the bass quality of these.
