Silver RX 5.1 System Review (Silver RX8 floorstanding speaker, RX Centre, RX-FX and RXW-12 subwoofer)

"Now more than ever, Monitor's determination to offer audio products that deliver high-tech engineering at a fair price is especially welcome, and there is no better example of this than the firm's newly released Silver RX."

"Look at this system, in particular, if you like the idea of mid-priced speakers that probe the limits of sonic resolution and detail in ways that will remind you of much higher-end speakers. Expect an accurate, sensible size and overall build quality; the Silver RX speakers are compact enough not to dominate a room, yet they'll treat you to lovely woodwork and drivers too beautiful to hide behind grilles (unless you must, to keep children's fingers from poking at them)."

Bringing Home The Silver!

“The gorgeous Rosenut veneer on our samples is the best simulation of genuine rosewood I’ve ever seen."

“…the bass from the Monitor system was as impressive as any I’ve heard in my listening room.”

“The RX8’s neutral midrange lacks any identifiable coloration, and its high end sparkles with detail. It’s a lively, arresting sound, with no false emphasis anywhere.”

“...with the Silver RX speakers and sub, firing on all cylinders, orchestral soundtrack scores sounded spectacular.”

“From vocals to drum kit to piano and instrumental shadings of all varieties in between, the sound through the Monitor system was luscious.”

“No single piece of material I auditioned blew me away more than the opening 15 minutes of Star Trek (2009). Music, effects, dialogue, and bass all came together in a spectacular way. Even at the highest playback level I could stand, the sound was highly detailed and never grating.”

“…I can say that for less than half the price of a pair of PL300s alone, this Silver RX system is a very special value—and an incredible ride.”

Sound+Vision RX6 System Review

“A do-it-all system that has the looks and the power...”

“The percussion stood out from the group’s sonic fracas as if I were hearing the music performed live in a small club.”

“At the other end of the sonic spectrum, the RX6 staggered me with its deep, dynamic bass… For a small speaker with two 6-inch woofers, the RX6’s performance is astounding.”

“The RXFX surround speakers’ timbre matching was superb — as objects flew past me during the movie’s driving scenes, the sound effects were remarkably consistent as they shifted from the front speakers to the surrounds. This characteristic helped the system produce an enveloping effect that drew me into whatever I was watching.”

“I’m surprised at the raw power of Monitor Audio’s Silver RX speakers. I’m delighted at their vivid sonic imaging. And I’m charmed by their gorgeous
looks — with or without the grilles attached. If you’re seeking a compact, do-it-all system, I doubt you can do much better than this one.”

Bought 2 x B&W ASW 610's and just couldn't seem to get the coherence or slam that I wanted from HT use. Decided on a RS-W 12 in conjunction with a B&W PV1. To say that I am impressed is an understatement. This sub is phenomenal. The low down grunt is one thing but the amount of control is insane. A 12' sub normally does well with music or HT but this sub does both stunningly well. Wish it had a mic for calibration though. Beside that I would highly recommend this sub. It is truly a feat of engineering. Well done MA for such an incredible speaker....

This subwoofer is insane! I've just watched my first two movies with it and the power is incredible. Bass is tight and room shaking, while it has a relatively small footstep, it looks beautiful and is very easy to set up in your room. What can one want anymore? I am in love with it!

Many subs have come and gone in my system, and I do mean a lot. Some did a few things well and some did many things not very well. And to be honest, a few were near perfect. But there was something missing even in those. I could not sit back and say wow, that sound is perfect. That was until I purchased the RXW12. I cannot find a fault with them. They do everything I ask of them and then some. I have always purchased British speakers but this was my first Monitor Audio. What have I been missing all these years! Time to make the switch. Keep up the good work!

I've had one of these in my Radius 7.1 MA system for maybe 3+ years and it never fails to impress, whether HD video sound or music, of all types. Visitors can't believe the sound, nor where it's coming from - until I show them the monster! My only gripe is that the diecast model cars I sit on it often get bounced off onto the carpet. My fault ... obviously.

I've had the RXW12 for over 3 years as part of a Radius surround sound system. It's magnificent. It make the small Radius speakers sound huge. Just watching Frozen Planet on TV was a totally immersive experience
