RBH SX-6300/R Tower Speaker Introduction
RBH Sound, based in Layton, Utah, is a manufacturer familiar to anyone who regularly visits the pages of Audioholics.com. Their products have long been a favorite with manyof Audioholics movers & shakers, including Gene, who’s main listening space fairly bristles with RBH Sound’s products. In this review we’ll be looking at the RBH Sound SX-6300/R floor standing loudspeaker. A relatively new product for RBH Sound, the SX-6300/R is a 3-way, bass-reflex system, sporting 6 (!) drivers bolted into a nicely built cabinet. The SX-6300/R is part of the new Signature SX series, which in turn, replaces the previous award-winning Signature Reference series. The "R" in the SX line designated usage of RBH Sound premiums Status drivers similar to the "Reference" designation from the Signature Reference line. It has been a while since I’ve had a chance to look over & audition an RBH Sound product so I was curious to see what the new line was all about.
The RBH Sound Signature SX-6300/Rs arrived in two large shipping cartons. Each speaker was packed in a series of 5 styrofoam collars and covered in a cloth sock; a fairly common packing arrangement. Extracting the speakers from the cartons was quick & easy, especially for the speaker shown at the right of the left hand picture – the carton is such a wreck it’s actually held up by the Styrofoam blocks! The carton itself arrived pretty well beat up with large holes torn into it, (only) one of which is shown in the above right photo. I was pretty sure the speaker it contained would have been damaged as well, but it in fact it survived shipment unscathed, a credit to the design of the shipping carton and packing materials that protected it. I was also told by RBH Sound that these were demo units used at various trade shows and to expect blemishes in the finish but they nevertheless appeared to be in excellent shape to me.
Let's take a tour of the new RBH SX-6300/R speakers from inside and out to see how these gems perform.

It's too bad RBH only sells to the little audio shops.
They list 3 shops within 100miles of me, none are convenient by any means.
Last time I tried to find one, they were closed! Owner works “bankers hours”!
It seems like everything i purchase these days has to be shipped to me!
It's too bad they don't sell any of the upgraded products through their EMP site.
These look VERY similar to the RBH manufactured EMP E55Ti…
As a former owner of the EMP EF30T and current owner of the EMP E55Ti; I'd be interested to get some opinions on how these compare.
While they have a similar driver compliment, the EMP's don't compare to the RBH SX/R series of speaker. The EMP's are fine speakers for the money, but the RBH's are in a different league. The RBH's use a Scan Speak 9500 series tweeter which is arguably one of the best soft dome tweeters ever made. The driver cost alone is about $150 per tweeter. The RBH's use cast baskets with vented pole pieces and much higher excursion woofers than the EMPs.
I've spent years listening to RBH and EMP products and while they share some of the tonal characteristics of each other, RBH proves you get what you pay for!
I'll see if I can get a pic up later.
I would prefer to go grill-less but my dog's tail would whip right through one of those woofers.
It's worth noting that the RBH line has thicker fiberboard and very likely more robust construction all around. Though, I can't say I've found the construction of their internet direct EMP line up to be lacking.
My big question is whether or not those upgraded drivers are really worth a $2800 price difference! The bass performance is probably better, but I cross over the E55Ti's @ 60hz anyway. The sub should do better with anything below that. (TC LMS-R 15"/Crown XLS2000/20hz tuned port)
Is that a Piano black finish on your system? It looks pretty nice!
