Review: Don't wait too long... - I have wanted these speakers since getting my first pair of KB-15's, an earlier model made for Best Buy (5.25" LF/1" Al dome driven horn HF) and bargain priced at $130/pr shipped. I was amazed at their sound and sensitivity (efficiency). I A-B-ed them with mythen previous favorites - a pair of NHT SuperOne 2.1's bought new 12/14. Their great sensitivity over the NHT's almost sealed their fate - the small Klipsch speakers were moved to my hobby room, where they have been seriously enjoyed. My NHT's remained in my office, an 11' x 12' room where they are driven by an Onkyo 50 Wpc stereo receiver (TX-8020) and CDP (C-7030). I was pleased with the controlled bass and decent treble of the NHT's - but the midrange appeared lacking - I thought that the RB-81ii, with it's 8" LF driver and 1" Ti horn HF driver might be the answer. They seemed to have evaporated last winter. I checked desertcart for Prime stock of the speakers aperiodically - including a few weeks back, when I found them for $249/ea - a great price for the top of the line bookshelf speaker in their 'Reference' line - so I ordered a pair. I felt guilty - and cancelled the order the next day. Last Saturday, I checked - they were still available - I ordered another pair. I was determined to get them this time and they arrived Tuesday - in a word wow! They are large and heavy, which I was prepared for, having moved the bookcase's next shelf up allowing 22" vertical clearance. They are fed by #14 stranded zip cord, with the HF/LF jumpers in place. The front firing port allows placement of the 12.5" deep speaker in a 12" deep shelf, canted inward.. The coverage is wide - my ears are centered two feet in front of the plane the speakers are in and equidistant from the speakers (~5 ft). The stereo effect is consistent almost to the back wall (8 ft) and covers a cone three feet wide at my seated central position to six ft wide in front of the back wall. The LF is there, while the HF are great - and the MF is now present! It also takes a lot less to drive these speakers - my half-power HD < .03% can be appreciated (<.08% @ 50 WPC). I may have found my ideal speakers! If you think you might like them - don't wait too long - order your's. Oh, if they get any better after break-in... I'll be shocked. Besides being bi-wire capable, they have a nice grill cover that is held in place by magnets. The instruction manual is multilingual and pretty sparse. They come individually well-packed, too. My s/n's were ~100 apart... they looked identical - perfect - and 'factory fresh' - quite decent quality.
Review: GREAT BOOKSHELF SPEAKERS !!!!!!!! - THESE 2 WAY SPEAKERS ARE NOTHING BUT OUSTANDING. THESE Klipsch RB-81 REFERANCE SPEAKERS ARE ON THE DISCOUTINUED LIST, BUILT LIKE A TANK, & THE SOUND IS SO CLEAR EVAN AT THIS PRICE POINT. THE SOUND STANGE IS EXPANSIVE WHEN YOU DRIVE THEM A LITTLE / LIKE A RACE HORSE. THE HIGHS ARE CLEAR & CRISP WHILE THE BASS IS TIGHT WITHOUT BOOMING OR EXHIBITING ANY FLABY DISTORTION. ( EXAMPLE ) GET A PHIL COLLINS CD & PLAY IN THE AIR TONIGHT & YOU WILL FEEL LIKE YOU ARE AT A LIVE CONCERT. TRUE, THE MIDS ARE A LITTLE THIN BUT WHAT DO EXPECT FROM A 2 WAY DESIGN. THESE SPEAKERS ARE IN MY BASEMENT BY THE BAR & EASILY FILL THE ENTIRE ROOM. UPSTAIRS FOR CRITICAL LISTENING I HAVE A SET OF 4 WAY, TOWER, STUDIO MONITOR SPEAKERS WITH A COST OF OVER $ 24,000.00 VERSUS THE Klipsch RB-81 BOOKSHELF SPEAKERS DOWNSTAIRS AT A COST OF LESS THAN $ 400.00 IT'S A NO BRAINER. THESE RB * 81 SPEAKERS ARE THE REAL DEAL SO YOU BETTER GRAB THEM WHILE YOU CAN BEFORE THEY ARE GONE.

## Questions & Answers

**Q: Any hiss heard in horns during quiet passages?**
A: This is typically on account of your integrated receiver's THD - on my Pioneer and Mcintosh (both of which have a THD of .005) the speakers were pitch black BUT when I hooked the exact same speakers up to my Rotel Integrated and separate amps (THD .3) there was always an audible hiss, it drove me NUTS - it's actually the reason I got rid of the Rotels. So even though horn tweeters are more sensitive and more likely to hiss - that is not the case with these - it's probably the stereo unit. Hope this helps.

**Q: Can these speakers be laid down sideways? I don’t have 19” space between shelves**
A: You could do that if needed i suppose but i will say if you are tight on space i would recommend looking at something a bit smaller. These are beautiful speakers but they definitely require some room, not your average bookshelf speaker by any means.

**Q: could you use two of these side by side as a center speaker to match my dual 8in  R-28F fronts ?**
A: Yes. however, the tweeter is a 90x60 degree directionality. 90degrees horizontal and 60degrees vertical. If you turn it on its side, the vertical axis become the horizontal axis. So if you watch movies alone, it may be perfect. But i find the 60degrees a bit narrow, and easy to go in and out of the directionality of it. 90 degrees has better fall off. But horn tweeters seem to be a lot more directional than other tech. YMMV

I love horn tweeters for movies. Simultaneously more nostalgic theater sound and very crystal clear on sound effects. Works well with speech too.

**Q: is this a pair (2 speakers) or just a single unit?**
A: This is a single speaker.   You would need to order 2 for a pair.
