Klipsch RB-51 II Bookshelf Speaker Pair in Black with 5.25-inch woofers and 1-inch LTS Tweeter

Got these hooked up to my vintage Sansui 7900Z stereo receiver into my tv, Bluetooth, Blu-ray etc. they sound fantastic and for the price I paid, I’m a happy customer.

It was tough buying speakers during COVID- can't go anywhere to test them out, just have to read reviews and make sure there is a return policy in place. I purchased 3 speakers before I settled on this one. The first was the Polk T15- was not impressed. Too bright with little substance. The second was the Andrew Jones Pioneer speaker- I liked these and almost kept them, I probably could've been happy with them if I did. I just wanted a little more bass and something that sounded a little better on the high end. It had a great balanced sound but the high end was a little muted for my taste and it needed a sub. The third I tried was the Elac Debut 2.0 6.2. I expected these to be the best thing since sliced bread but honestly I wasn't that impressed. They had a nice full sound, and even made me think the Pioneers sounded tinny after listening to them, but in the end they are nowhere near worth the asking price and I ended up returning them preferring the Pioneers in the end. All of the speakers needed a sub to sound good.Then I gave these a try... The clarity on these is exceptional. With the right audio track you will be very impressed. I do a lot of quieter listening and the titanium horn speakers are excellent at sounding good at lower volumes. I'm not throwing ragers every night so I don't need to shake the foundation. I prefer a bright sound but also appreciate the full range of the bass to be included. The frequency on these don't go as low as I would have preferred (on paper anyway) but the bass really is strong where it's at. If you have a good amplifier you will most likely be happy with the bass after the proper break in period.To specifically answer the question everyone asks- how's the bass? I will answer specifically.I find the bass to be very good on these. I remember thinking I needed a sub with the first four speakers I purchased and when I had these hooked up with a sub I thought there was WAY too much bass. I kept turning the sub down to the point it was basically off and subsequently I just returned the sub. If you have a good receiver with bass controls and are a casual listener, I think you will be more than happy with the bass output from these speakers.If you have a smaller living room or den area and need some speakers I would not hesitate to buy these again. I bought these for $199 on an Amazon Warehouse Like New listing and think it was worth it.If you are deadset on having a sub while on a budget and don't like the "Klipsch horn sound", The Andrew Jones Pioneer are a solid choice as they are well under $100.

Ok. if you are one to spend thousands on your stereo equipment, you obviously wouldn't have shopped for these anyway, but would have been looking at the Palladium line. i am no longer single, and must contend with a wife who sees no point in . . . well, that is not relevent anyway! these speakers are a dream. my set up is a yamaha a700 aventage receiver, with a klipsch 500 home theater system. and those speakers are great, don't get me wrong (incredible sound in a TINY package). but i wanted a little . . . more. i struggled with whether to get the 41s, or maybe splurge up to the 61s. but i am very happy (and i believe smart) with the rb 51 ii speakers. they add . . . oomph, but don't detract from the satellites of the 500 system. in fact they prove the perfect blend, from the 8" subwoofer cone to the 5 1/4" 51's cone to the 2 1/2" satellites. then the 51's 1" tractrix horn and the satellites 3/4" tweeters blend amazingly. you will just not believe the sound these small but heavy speakers make. music is just amazing. i put on Rush's Moving Pictures to test out the dynamics (loud - soft, synth - guitar, drum breaks, etc.) and even my wife had to admit it was just . . . amazing. can i say it enough??? the yamaha has its patented pure direct switch which actually allowed me to listen to just the 51s and i was even more impressed with the sound they put out. we then watched Star Trek, for the special effects, and the explosions rocked us, scared us a little, even! my living room, i suppose, would be medium-bordering-on-large (about 20x25') so if you have a truly large room, then perhaps the 61 ii or 81 ii would be money well spent. or just go with the 1300.00 51 home theater system and just be done with it . . . it would be money well spent. but goodness, considering i was adding to an already bought system (the 51s became my main l/r speakers, and the satellites allowed me to upgrade to 7.1 sound) i am just so very grateful to the techs at klipsch. i realize i sound like a paid advertisement. but i'm not. my system finally sounds how i've always envisioned it sounding. it is, without a doubt, the best 421.32 i have ever spent.

I bought these to go on my desk top for near field listening. They will be powered by an 8 Watt per channel single ended tube amp that I am still building. Maybe just a little large for my desk top, but they are the smallest I could find the extend to 50Hz and the fit/foot print isn't that bad. Plus, I am a diehard Klipsch fan. Although my SET amp isn't ready yet, I am listening to them right now on my 35 WPC push pull tube amp. These definitely extend to 50Hz and sound fantastic. The bass, mids and highs are perfectly balanced. Really, it's had to believe the quality of tight defined bass that comes from these small boxes. Mids and highs are as clear and detailed as you'd expect from horns. My normal speakers for the room are large Klipsch KG series floor standers that extend to 36Hz and have large drivers with a big box. The RB 51 IIs can't compete with that, especially the "slam" factor of big drivers, but if you're listening to classic rock, Jazz or really anything but (unnaturally) deep bass dance club music, I don't think you really miss it. These are going to be great for my intended use. They are great right now filling my 11X14 listening room. I am a 2 channel stereo guy, but adding a powered sub to these would put a lot of big floor-standers to shame, I think.
