Klipsch Reference R-51M Bookshelf speakers

Where are Klipsch speakers made?

These Klipsch Reference R-51M bookshelves are a great choice for LP listening Carlos, but you will need a receiver connected between your sweet Audio-Technica LP-120XUSB deck and the speakers. IF you do not want another piece of gear, consider using the Klipsch R-15PM's in the link below. These speakers have an amplifier built-in, so you can directly connect your new turntable to these and enjoy! https://www.crutchfield.com/p_714R15PM/Klipsch-Reference-R-15PM.html

Can Klipsch bookshelf speakers be set up on their sides, without effecting sound quality? I have height limitations in my record room.

These Klipsch R-51M Bookshelf speakers are manufactured in China, Steve. Speakers from the Klipsch Heritage line like the Heresy IV's in the link below are handmade stateside in Hope, AR. Klipsch continues the longstanding tradition of fine hand-built speakers, and that quality is apparent even in models made overseas! https://www.crutchfield.com/p_700HRSY4CH/Klipsch-Heritage-Heresy-IV-Natural-Cherry.html

are these speakers blue tooth compatible?

These speakers dispersion, optimized for when the speaker is upright, would be impacted when rotated 90 degrees and may not sound as room filling. We do not recommend installing these on their side. Instead, we suggest contacting an advisor by calling 1-800-324-9695 to get a personal recommendation

Are there limits I need to know before buying a receiver with correct watts-ohm's for these?

These are not powered speakers and do not have Bluetooth functionality. These speakers would require an amplifier or receiver. For a similar set of powered speakers with Bluetooth, we may consider the R-15PM, which is linked here: www.crutchfield.com/p_714R15PM/item.html

Does the speaker wire come with the speakers?

Excellent bookshelf cant go wrong with these sound great with a sub If you getting a amp with more power go with the rp-600 or rp 400 enjoy whatever you decide...

david Mar 04, 2022

Klipsch speakers are very good with low power amps. Having said that, I would recommend a high quality amp with the most power you can, or want, to afford without greatly exceeding the max advertised power of the speaker(s). The R-51M is 8 ohm compatible with a published power handling capacity up to 85 watts RMS or 340 watts peak power. Power these with a 50-75 watt high quality amp and I think you will be pleased.

What should I set the crossover frequency for these?

philip Feb 23, 2022

Speakers only it does not have wire that comes with it do you have to order that separately Enter an answer to this question.

paul douglas Feb 23, 2022

No. I got the wire separately.

How would I wire these 2 speakers up with an amp that makes 50 watts per channel at 4 ohms to make it the 8 ohms it needs? And there is 2 channels.

Set the low-pass filter to 80 to 100 Hz. Set the high-pass filter to 60 to 80 Hz. To make it easy on yourself, set both filters to 80 Hz and adjust to taste.

ronald Jul 15, 2021

I couldn't tell you that specifically. They are hooked to a kenwood receiver from the seventies at my moms. I did adjust the bass and treble knobs a little bit.

jordan d Jul 01, 2021

Not sure if this answer will be of any assistance or not; the pair I have is in another location and, if I remember correctly, there is no crossover adjustment on the speakers. If you're wondering about a sub's crossover frequency, paired with these speakers, I've always thought that to be a subjective choice, and/or a matter of personal preference, i.e. does one set the crossover above the lowest freq response rating, in the mix with the lowest freq response rating, or below. But, as I said earlier, I'm afraid this response may not be of much help. Best wishes.

What kind of kkipsch speakers can i use for the Yamaha amplifier?

It is not possible to make each of these speakers present a 4 ohm load to an amp. The good news is that an amp which can handle 4 ohm loads will also handle 8 ohm loads. It should work with the chance that the amp will output less than 50 watts. If the specifications do not state how much less and you want to give the speakers the 50 watts RMS they can handle, I recommend contacting an advisor by calling 1-800-324-9695 to discuss the setup and any other goals you have to get a personal recommendation on an amp that will work.

Can these speakers be used for rear surround speakers?

Klipsch R51 or R41 with a subwoofer work great with Yamaha receivers. I have a Yamaha TSR 7850. They both have very high efficiency and get loud with less power.

richard Jul 25, 2021

As long as your amplifier has speaker output any bookshelf, floorstanding or satellite klipsch speakers will work.

Absolutely! I use them as my fronts in my set up and I use the R-41M for the rears. They sound amazing together!

jason Jan 31, 2021

Yes I am using them for my rear & they work great

terry Jan 31, 2021

Yes they can, and many other speakers as well. Do keep in mind these are passive speakers and hence need to be connected from an amplifier output. Active speakers, which these are not, have their own amplifier and need a preamp connection. So assuming you already have a HT receiver, or a HT preamp/amp you can use these as surround speakers. And they will do an outstanding job at it. These are really great speakers. Klipsch designed a winner here. I have used them as main L/R speakers with a subwoofer with really satisfying results.

derwin Jan 30, 2021

I don't know. I haven't tried to use them as surround speakers.

WILL AN INTEGRATED AMP WITH 40 WATT RMS 4CHANNEL WORK WITH THESE SPEAKERS?

nancy Sep 16, 2020

Will these work with a Mac1900?

These speakers sensitivity rating is 93db. So they are more efficient than the great majority of speakers out there. Hence, they will require less power to reach similar volumes than other less efficient speaker. As a rule of thumb, sound from these will be perceived twice as loud as a 90db efficient speaker. I have used these with a 50watts per channel class D tube amplifier with satisfying results in a 15'x 25' room.

derwin Jan 30, 2021

Probably. But you might have to push the volume a little higher since the wattage is pretty low. What is the amp integrated with?

greg Aug 04, 2020

can you pair these with klipsch promedia 2.1 computer speakers / sub? will i need a splitter of some sort?

i run my r-51's through an old analog nad 7045! they crank with very little volume! they're clear with no detectable distortion! the classic 1900 should be a perfect match!!!

brian Aug 05, 2020

Why....yes they will, if you have banana plug connections. If not you'll need adapter with left and right connection or you can just strip the wires,observing polarity......of course. Enjoy!!!!!!!!

luis a Aug 05, 2020

If it's the old school receiver, then yes, it should work.

How do these compare to the R-15M? Is it worth upgrading to these?

I'm not sure. I used them for my 7.2 surround system. I wish I could be of any help. But I'm really not sure. I would contact Klipsch directly.

jorge Jun 20, 2020

This depends entirely on the subwoofer. If the sub has normal (+ -) connections for the speakers, then yes. If it has RCA you'll need RCA to speaker wires, and if it has something else, probably not. Or not easily.

taylor Jun 20, 2020

i am using mine with a 10inch klipsch powered sub. im sure it would work as long as the amp you are using has a sub line out. these are not powered speakers like the ones that come with the pro media. an amp or receiver is needed.

i bought a pair to upgrade from a pair of Sony SS CS5s. I would suggest upgrading to the Premier Reference series, these don't have the base response or high end I expected with Klipsch. The tweeter in this budget model is aluminum not titanium. The cases are very thin. These might be ok for a theatre system but in a 2.1 audio system you will be disappointed. Soundstage is nonexistent both high and low end response is subpar. I've always been a klipsch fan but this speaker is obviously designed for the mass market. Upgrade to the Premier Reference series it's worth the $.

brett Dec 05, 2020

The 15s and 51s are basically the same thing. It would be a better investment to upgrade to RP bookshelf speakers than to the 51s.

taylor Jun 20, 2020

it depends more on price. at the price i paid for the R-51's (124.99), it's worth picking them up on their own! the sound is terrific!

brian Dec 03, 2018

Not familiar with the R-15M, but I'm very pleased with the R-51M speakers. My only suggestion would be if you are going to get the R-51Ms, make sure you have a decent subwoofer or pair them with another set of speakers with a substantial low end. I have my R-51Ms paired with a set of Elac B6s "and" an old Infinity sub. My goal with buying the R-51Ms was to raise the ceiling of the highs and enrich the mids that my Elacs were lacking. Adding the sub just rounded out the bottom end and really added some extra bass punch. I read somewhere that a great way to get better performance from your speakers without spending a fortune was to pair two sets of speakers that have different strengths. I can verify that my "Budget Wall-0-Sound" kicks ass and it didn't have to sell any of the kids to do it. (Though I've been tempted) If the half price sale is still going on, take advantage and pick up a pair of these. Hell, you can always send them back if you don't like them. But I think you will want to keep them. Cheers!

michael Dec 03, 2018

I Think the 51 IS JUST A NEWER MODEL THE 15 THE LOOK ALMOST THE SAME WITH SOME MINOR DIFFERENCES THE SOUND ON THE 51 SEEMS A LITTLE BETTER BUT OVER ALL IF YOU HAVE THE 15'S SAVE YOUR MONEY FOR NOW.

lathrop Dec 03, 2018

Well if your referring to the R-15pm. I'm not sure the R-15pm are powered speakers. The R51m are not. I haven't heard the 15pm's so I can't give you an honest answer. But I'm using four 51m's as my surround and surround backs, and I'm using an Emotiva power amplifier with a Marantz pre amp and they sound amazing. For both movies and music. You won't be disappointed.

jorge Dec 03, 2018

Never heard R-15M so don't know

david Dec 03, 2018

The R-51M seems to be the same speaker as the R-15M judging by the speaker specs.

darren Dec 03, 2018

I can't answer this question as these are a Xmas present for somebody else.

steve Dec 03, 2018

Sorry, I've never heard the 15's.

gregory scott Dec 03, 2018

Can these be mounted on the wall?
