Excellent, detailed, and vast soundstage when powered by dedicated amplifier per speaker. I immensely enjoy the tiny little detail it pulls from the music, and how great your amplification is, definitely need to pair them with a decent sub to get the full range. These guys really need lots of good power for them to sing, and if you can provide that, you'll have some amazing speakers. I've not seen them come on the used market seldom, but if you see something around 1K in good condition, jump on them, as they're amazing speakers.

Nothing really, may need to incorporate a sub, and we all do these days.

Imaging, resolution of soundstage, speed, price, looks...

Not a weekness when achieving optimum performance of these but absolutly require top end quality amplification and a sub, preferably stereo subs.

Have had the 420DX since 2001 and also had the 520DX and 220DX. Frankly I feel the 420DX superior to the 520DX and sold off my 520DX's. Don't bother with the 220DX by the way, it is not sonically matched to the 420 or 520 speakers. Also have x1 and x3's which are my home theater setup and in that application they are good (x1's across the front and x3's in rear).

YOU MUST HAVE EXCELLENT QUALITY AMPLIFICATION FOR THESE SPEAKERS.
Anything less is wasting your time and money. The prior reviewers who state this are dead on. I originally drove these with a Luxman, than a Citation 7.1 amp but evolved to a Reference Line Preeminance One Silver Signature SS amp with the matching Reference Line Preeminance Two passive preamp (you have to watch for these to pop up once every year or two used on audiogon and don't let someone else buy it before you do!!!). Complete transformation with this amp. These speakers present such a real soundstage and resolution it can be scary amazing. In a very good system these will allow even the minutest component change come through. Dropping in Luminous Audio Synchestra Reference interconnects took these speakers up yet another notch. I do use a pair of subwoofers through a marchand crossover and seperate power amp with these and that likewise is a requirement for these speakers (stereo subs that is). Again, the imaging these speakers are capable of is truly amazing when sitting in the wide sweet spot. I do wonder what a pir of ACI or HSU subs would do here.

I cannot imagine replacing these in my system, ever.

Customer Service

Actually found customer service to be quite good when I used it for x1. Packaging on the X1 was very poor leading to shipping damage. The company replaced the damaged speaker when I brought this to their attention. Packaging for the Radia series (420dx, 520dx, 220dx) was very good.

Great sound, particular highs. Relatively small footprint. Classy looks, quality fit and finish. Quite a huge value!

OK, so I moved into a new house and wanted to update my 5.1 speakers. Out went the old subwoofer and in went a new Velodyne HGS-10 subwoofer. Yowza! That was nice... Next, I read some good reviews on BG speakers here and saw a deal on two front X3's and one center channel X1 for $550 brand new on ebay. Decided to try them and was not disappointed. First off, I HATE speakers that have peaky highs because now that I'm older, peaky highs do nothing but irritate me. Thankfully, the X series here are crystal clear yet have no apparent peaks in high end response. They are just so detailed thanks to the wonderful, trademark BG tweeters which to my surprise aren't electrostatic ribbons but planar magnetic. The speakers do not have low end heft but have sufficient bass as to sound quite acceptible and pleasing without any subwoofer support. These speakers are easy to drive (Audiosource monoblocks) and fill my large family room (with high ceiling) with the utmost of ease. Unlike others, I found these speakers enjoyable right out of the box and now that break-in is done, they are still very detailed, just smoother. My room's rear cannot accomodate another pair of X3's so I have wall pillar-mounted NHT SuperZero XU's. The combo is GREAT and the best part is that this audiophile sound was achieved with a relatively low budget. As for fit and finish, the X3/X1's are excellent. Not GREAT, but certainly what I would expect for sub$2000 for the set. For whatever reason, you cannot get these speakers from traditional brick and mortar audiophile shops, but rather through "independent" online dealers and ubid.com. All I know is that for what I paid, I am immensely pleased.

This review is for the Radia X series. I purchased 4, Radia X3's and an X1 for my center. These speakers are absolutely amazing. As others have posted, they are highly underrated and unknow to many. One look at the craftsmenship out of the box and you will be pleased. They are not only an eye piece, but create an amazing sound stage. I recently completed my dedicated HT and still don't have the room completely "acoustically correct", however, the sound is stunning. At first, they do sound a bit tinny which is common before break in with many speakers. I set up all 5 speakers and let my reciver play a series of cd's ranging from classical, to alternative, to jazz, to rap and let them break in slowly. 100 hours is the recommendation, and I belive this to be true. I have about 70+ hours or so on them and they are warming up quite nicely. Their bass response is not great, however, I've actually been able to get fairly good results due to the construction technique I used in the room. DEFINITELY add a sub to these. All of their speakers are know for their crystal clear high's but the bass is definitly lacking. I've paired them to an SVS 20-39 PCI sub and it completely rounded out the package. I'm powering the system with a Denon 3803 and I couldn't be happier with the setup. I highly recommend these to anyone looking for a solid competitor without breaking the bank.

Transparency, imaging, depth. Even sound transparent at low volumes. Much easier to place than Maggies or Quads.

No bass, no highs above 16 KHz, Dip in the lower midrange (800 - 2 KHz) can be easily fixed with a decent EQ like the Behringer.

This is a review of the 520DX which contains the 50-inch ribbon as opposed to the 40-inch in the 420 unit. These speakers are criminally underrated which is fine with me. True, they have no bass under 80 Hz or so. You need a sub. Due to the slim baffle area (under 8 inches) they also suffer from cancellation effects which produces a thin sound. This cancellation results in a suckout of 3-4 dB from 800 - 2 KHz. These always sounded great to me but suffered from the thinnness until I tried a GOOD EQ. Amazing transformation, now the Radia 520DX is almost as good as any speaker I have ever heard. The only speaker I would trade for this one would be the Maggie 3.X series. They do look sexy too.

RADIA X-series (x5) WOW! I love these speakers. I used to have Paradigm Studio v.2 speakers (which I also loved) but these are definitely better! The clarity and realism of voices are unreal. I thought that the vocals from my Paradigms were good but I've always loved the realism that ribbons provide (was going to purchase the Maggies MG-12 but read that they are finicky about their placement). However, I have to admit that these Radia X floorstanding speakers lack bass response. In fact, even the mid-range is weaker than my Paradigms. Imaging and resolution are wonderful with these speakers. I've tested these speakers using bryston and anthem amps at a local hi-fi store and compared their sonic character to PMC speakers and Mirage. No where close! The PMC's were $10,000 cdn. and the only thing they beat these BG's in was the bass response. But who cares if you have a subwoofer. Overall, couldn't be happier with this purchase. Absolutely loving it! Definitely consider these if you're looking for speakers!

I just pocked up the Radia 5 channel speaker system from UBID. I love this technology and they sound great so far. I am still breaking them in as the specs mentions normal use of 100 hours. I have hooked these up to my Pioneer Elite 43THX receiver and it compliments it very well. Looking forward to some great tunes and a new listening experience. I wish BG would produce a sub woofer, I also picked up a Dahlquist 12" unit. A sub woofer is definitely required.

I bought the 520 Radia from UBID at 1400 including overnight shipment. They are used as my rear end speakers for my DVD-AUDIO setup. My main speakers are POLK SDA SRS 1.2TL. I have 2 Sunfire Signature amps powering the Polks and One Signature amp powering the 520'2. Additionally two Sunfire signature amps round out the low end frequency response. All I can say is that it is the swetest setup I have ever heard the 520's do wonders in a DVD-AUDIO setup, beatiful sounding speakers. Playing DVD movies is also awsome, great rear end effects. Sunfire Low end frequency response is just an awesome companion for the Radia 520's. Listening to Beethovens symphony #9 on DVD AUDION is just phenomenal, the POLK SDA SRS 1.2TL are beautifully complimented by the Radia 520's Best $1400 ever spent on speakers (Except for the POLK's.

(Aliminum 520dx) These speakers sound as good as they look, which is saying a lot. They are 5'8 and have are aluminum brushed. They guve up LOUD clean sound, with little or no base, which make them perfect front or side/rear (7.1)speakers. These speaker must be accompanied by a subwoofer and it is good to get a center channel with a built in sub as well. Use correctly these speakers are worth every cent and will give you contless hours of great movice and music listening.

I purchased the X3's with the x1 Center channel for my home theatre setup. I am looking to get a matched set for the rears in a 6.1 setup. I love these speakers especially for the price. While they are not as transparent as typical planar speakers they still sound quite nice. The midrange and highs are particularly noteworthy. The bass as stated before is not great but I've paired with a subwoofer and roll the speakers off at 60 hz and am quite satisfied with the overall sound. I have listened to many speakers in this price range (list is about 1,000) and have not found anything close. The sound is so clean and undistorted particularly the highs. They really shine on acoustic music, and vocal solos. Played Peter Frampton live on these speakers, turned up the volume, and felt like I was at the concert.
