Q: Can I use this as my rear speakers? My front speakers are Klipsch R26
A: These are working great as both surround and rear speakers in my system
A: There actually is no keyhole on the back. For some reason, Best Buy decided to put pictures of different speakers in for the imaging of the R-51.
A: 9 pounds 15 ounces for one individual speaker. Just checked it with my digital fish scale.
Q: How is the bass responds on these speakers and is there any harshness to the top end.
A: Don’t have the bass of a larger speaker but very good bass for their size. No harshness on top end if broadcast quality is good. Kind of a silky smooth sounding highs.
A: Hello Preorder: A receiver's RMS rating is supposed to be set against a "standard" and is an indicator of how much "clean" power a receiver can deliver to speakers at a certain resistance (OHM rating, 8 Ohms for example), and with the proper gage wiring and distance, etc..... You typically hit the "peak" power draw on the lower BASS response. So the lower tones generated by your music source and the higher the volume, the more power it takes to drive your speakers. To be clear, the 140W RMS receiver and the 85W RMS speakers need to be compared at the same resistance, so for example if these are both rated at 8 ohms, then what this means is you would be fine to use these speakers at volumes near 70% of what the rated output is for your receiver. So don't turn it up all the way, or you may run the chance of damaging these speakers. You should NOT turn it up all the way in any case because when you do, the receiver begins to deliver more "noise" distortion in the signal and that can potentially damage ANY speaker. Keep it at a decent volume under 70% and you should be able to enjoy these together just fine.
Q: Can I wall mount this speakers?
A: The answer is yes and no. They have a rear port on them so you can’t flush mount them; it would cause the speakers to sound terrible. You can however use a swivel mount to mount these. I’ll attach a link and picture so you can see how they work. These do not come with keyholes on them anymore .

A: Much depends on your budget and what you are willing to spend on an a/v receiver/amplifier. There are quite a few good AV receiver brands today. Review the offerings from Yamaha, Denon, Sony, and Marantz. I prefer a Marantz A/V Receivers although they are expensive. You get what you pay for. With the current ongoing sales, you can find good multi channel A/V receivers for less than $300. Yamaha and Sony come to mind for budget priced amps. If you go to inexpensive you may find yourself upgrading very soon. 50 years of experience with many thousands of dollars spent.
Q: Can these speakers sit directly next to a LG 4k TV on a mantle without affecting the picture?
A: Yes. The magnets in speakers could affect the stream of ions creating the picture on the old cathode Ray tube type TVs ( those heavy glass ones) but won't affect flat screen TV at all

Awesome Sounding Speakers
Pretty great pair of speakers. I had purchased them on sale so I thought, why not? Size wise, they were a bit large but no larger than other bookshelf speakers in its category. I'm not the most eloquent person, but I would say that the sounds of the speakers had plenty of clarity and was not muddied by the equally great bass. Pretty awesome pair for any fans of more colorful audio than the dry analytical sounds of more accurate ones. Would recommend a subwoofer though.

R-51 M
I purchased these R-51 M speakers as a rear channel for my home theater system. They are replacing my Bose Acoustimass 10 system. With only these connected and using the Klipsch RP-404C Center Channel, the sound is phenomenal. It's like I bought an entirely new system. There is a very noticeable sound quality difference. I'm running them through the Onkyo TX-NR656 amplifier. Also purchased at Best Buy. At this moment my sub and front speakers have not arrived. I purchased these through Best Buy's "open Box" program at a deep discount. They look and sound new. Keeping in mind I would have removed them from the box anyway to connect them. Best Buys loss is my gain, Thanks Best Buy. There is one drawback . Best Buy does not offer any reasonably priced speaker stand to match these speakers. Nor does Klipsch. I can live with that. I'm fairly handy so I will just make a custom set. This is necessary for my application. As stated these are my rear channel speakers. The connection is very simple. No degree needed. If you can screw a tire valve cap on, you can connect these with out difficulty. They weigh eleven pounds each. So rather than chance many of the stands offered and having my speakers crash to the floor I feel this to be my best option. Would I recommend these speakers? By all means. This is a reasonably priced, high quality addition most would be proud to have in their system. One final thought. Don't pass by those "open box" offers. You get good first quality at a reduced price when available.

Great Bookshelf Speakers for Rear Channel
I needed some speakers to use for rears that would somewhat match tonally with my Klipsch RP-150m fronts and RP-500C center. I was on a budget and got these for half price Black Friday. Timbre matching is not as critical for the rear speakers but these seem to be voiced similarly to the Reference Premiere line. Even when I listen to my SACDs in 5.1, the music pans from front to rear, the speakers blend in perfectly. Only complaint is on stock photos, there appears to be a keyhole on the back to hang the speakers on the wall. There is no keyhole on the back of the speakers so you have to come up with your own mounting method if you need to hang them. The magnetic grille covers are a nice touch that's rare in the price range. I appreciate the full size tweeter horn vs the smaller ones used on the previous R-15M, it really improved the tweeter dispersion. Really great speakers for the price that sound bigger than they are.
