What mean is there are many different configurations of the space behind a ceiling mounted speaker, not everyone can or wants to use the back boxes KEF offers. That volume of space behind it can affect the bass response of the speakers.

The Uni-Q driver in the Ci200RR-THX is a reworked version of the driver used in the Q900 floor-standing speakers. The one used in the LS50's is unique to those speakers and has better resolution. You don't really need the highest quality speakers in the ceiling because the sound they deliver is chiefly movie sound effects, rarely music. Even when they do music, the front mains do most of the work.

Check the layouts given for ceiling speaker Atmos installations given on the Dolby Labs website.

This is excellent news, time to take another look at these then. I really think that solves my only constraint on using them as mains. Appreciate the update.

Based on your answer, I am inferring that the LS50Ws are set up as mains L/R, off of the L/R pre-outputs. All the rest of the Atmos speakers run by the AVR and you are now able to maintain the setup through power up and down, including the REW, YPAO, Audessy etc. settings. Is this correct? Can you describe how you control them in the multi-speaker env. For instance do you set up a Harmony remote which handles the poweron process, or some other method? I realize these may be simplistic questions, but I am hoping my surmise is correct.

I am excited because last night I spent the evening listening to a pair of new LS50Ws at a local HT/Audio store. They weren't hooked into an HT setup, but with music they were very fine. I've begun saving up for a pair.

Community; Thanks in advance for any details about HT use, you might want to share

Best, Chris

It's just like with any other high quality speaker, the better the gear you connect them to, the better they sound. I used Parasound Halo when I still had my LS50s. KEF themselves demoed the LS50s originally at shows with Parasound gear. Bryston Cubed probably another good one.

Alright guys, looking for honest input. See my sig for prior setup (although the HSU hasn't been set up yet, I just took delivery).

I'm currently auditioning a pair of the new Q150s as mains in my living room, which is about 23x15x10. They are currently set on the mantle with the tweeter about 5.5' off the ground, aimed down and toed in at listening position (actually toed in such that the right is aimed at my left ear and left is aimed at my right ear), which is about where they will be once we get the wall shiplapped, and the TV/Speakers hung, except I'm sure the actual mounts will hold them about 4-5" off the wall. I'm currently using an NAD T748 which puts out a claimed 80wpc. My listening position is dead on 13' from the front lip of the speakers in the current position.

I'm not going to lie, the Q150s put out plenty of volume for us and blend very nicely with the 10" Onix Rocket sub that I'm currently using, and I would imagine will only get better with the sealed HSU 15". I, for the most part, very much enjoy the sound, though I do feel the vocal clarity could improve a little - I'm used to having an RC-7 as a center, which has often been called one of the best centers ever for the money.

That said, I'm considering moving up to the R100s since they are on sale through KEF, or possibly even looking for a pair of LS50s, used but in great condition. My question for you all is, given my setup, would I be spending too much money on LS50s (or even the R100s) if I can't set them up as intended? What I mean is: I absolutely realize my setup isn't ideal, so should I spend the money on LS50s? I've read they should be no more than 26" off the ground, or something like that. While I value the sound of my music more than HT, they will be used for HT/TV more often on probably about an 80/20 ratio - no one else in my home likes my music . I plan on running a 3.1 for now, and eventually a 3.2. If I go with the R100s, I can swing a used R200c. I know a single LS50 would be hard to come by without going through KEF direct, so the matching center channel on that choice might be put off for a while due to cost. What would you guys suggest with my setup and use?

The newest gen Wyred4Sound amps are said to sound good with the KEFs. I plan on trying a pair of mAMPs in a few months myself.

Whats your budget?

What about something on the used market that would be in the $3-400 range? I would only need about 100-150 watts/ch.

No, no real reason other than everyone makes it seem like they need 100-200 watts to really see their potential.

Are the LS50s not so good with rock music? I've read several reviews where they are compared to other speakers and while the LS50 wins with orchestra type music, they seem to pick the competing speaker for rock. Would the R100 be better for rock? What about HT?

They rocked pretty hard when I played my new Rage Against the Machine - Evil Empire SACD (Audio Fidelity) for the first time today on my lunch break!!

I played them in straight 2 channel with no sub and they sounded great. Steve Hoffman did a great job on the mastering.

Hi all

Desperate for some quick advice.

HT setup.
Just purchased 3 LS50s for L-C-R channels...will find some rear speakers later.

Looking for best receiver choice from the following:

Nad 758v3
Marantz sr6011
Denon x4300H
Denon x6200W

Obviously some are more expensive than others with better specs - but I'm asking from a safety perspective...what would safely handle the 3 front speakers and a couple of decent rears when I do that. I'm more of a video guy than audio so I only know enough to be a little concerned re the 4ohm issue..
Living room/home theater are is about 12x12 (10ft distance from couch to speakers) but open to dining room and kitchen. Moderate volumes.

Many thanks

Hi,

Yes, I have the Ls50w connected to the pre-outs on my Anthem MRX520. I have a Harmony Elite remote which I used to power on my media setup (receiver, kef ls50w, television, and nvidia shield). I then have it set up where the volume on the Harmony remote uses the AV to change the volume and not the Kefs. Its really a simple setup, especially with a Harmony remote.

Its actually a sweet setup as I use the the speakers and AV for movie and television. I dont like how the Anthem plays back music no matter what setting and room EQ mode I use, so I just connect my laptop to the PC port on the back of the Kefs and play music from Tidal.

I guess my system isnt conventional LOL. My center speaker is the Chane A2.4. I was worried that the timbre wouldnt match but I actually prefer it as a center. Its a little more neutral or a tad brighter than the warmish sound of the ls50w. This makes dialogue a little easier to understand during movie/television play back.

Hope that helps!

If you are patience, I think the best of those is the Nad 758 v3. If NAD follows through w/ their promise/plan, then it will have DIRAC vs Audyessy on the Marantz and Denon. DIRAC is supposedly superior, but unfortunately it is not currently on the 758v3 yet. A firmware in a month or two should be available.

Also notice, there are only 3 HDMI inputs on the NAD, so if you have more than 3 sources to connect to the AV, you might be out of luck.

A good compromise would be the Anthem MRX520. It does not have ATMOS support but if you dont intend to go beyond 5.1, it's rock solid and ARC (anthem room correction) is also very good.

Thank you.
I read somewhere that the NAD sometimes "shuts down" with speakers like these (?) which is why I wanted advice. I'll research some more as it has been recommended before.

Btw, I'm using an oppo 203 player - would it be better to use that as a processor and connect it to a multi channel amp? Just would have no idea about a reasonable amp (i don't have a lot of space either)

Thanks again

I have had my NAD T758 go into its protection mode (shut down) on me, but I deserved it. I had it playing my R500 speakers at above "0" for a few minutes, a really deafening volume in my home. The protection circuit did to save the receiver from harm (what it's supposed to do) and I'm grateful. The kid in me just had to try it.

by the way, you do think the MRX520 is powerful enough for 3 LS50s and some other rears?
I only ask because looking at the specs they don't seem to compare favourably on paper compared to the other models i mentioned (apologies if this is a very basic question)

thanks again

I am honestly not sure but there was a person who powered his ls50s of a Marantz slim line receiver and said they sounded no different than him running of a Nova amp. I think you will be fine.

As so it happens, I just picked up the NAD t758 v3 just to see how it compares to the Anthem.

Firstly, the NAD is a good 7-10lbs heavier than the Anthem so this may be an indication that the NAD has a better amp but not necessarily so.

Also, there was a user review on Crutchfield noting that there were HDMI troubles with the NAD, and I can safely say that my unit does not have any issues. I did do an immediate update right after I powered on the unit. I played some 4k/UHD movies on my Nvidia Shield and streamed some Netflix and Amazon HDR content fine. In fact, I say the HDMI connect on the NAD is better than the Anthem as I would get constant flickering on the Anthem.

The user-ability and menu on the Anthem is much better than the NAD. It is much easier to navigate around on the Anthem and everything seems much more logical. The NAD isnt bad tho and I think it is still better than the Marantz I previously owned. The NAD is also missing an ethernet port so any updates will have to be done over WIFI. I cant fathom why NAD omitted an ethernet port!

Finally, the room correction software clearly makes a huge difference. I have to try to run my speakers on the Anthem w/o ARC to see how they sound, but so far without any room correction on the NAD, the Anthem is clearly better. The bass from my sub (Rythmik L22) is so much more refine and distinct on the Anthem w/ room correction than the NAD without. The supplied mic NAD provides with the unit is inferior to the one on the Anthem. Hoping I can use my umik-1. Hopefully NAD comes through and correctly implement DIRAC. I bought my unit from Crutchfield so I have 60 days to test it and hopefully NAD can deliver the goods.

Those are my early impressions and I hope it helps.

Yes it does. Helps my planning and budgeting to know they are capable of what I have in mind. I have the Harmony as well. I'm happy with my Yamaha 3060 for music, so I'll be setting up slightly different from you. Since my center is an LS50 timbre matching won't be an issue. The goal is the same. Getting the best sound from the mains. I just wish they had included an output to enable using their DAC/wifi with other amps. So I guess I am keeping my powder dry for now. Hoping for some sale activity or improvements in the next 6-8 months. I think I'll probably make a move after the first of the year.

Best,
Chris

Best, Chris

As so it happens, I just picked up the NAD t758 v3 just to see how it compares to the Anthem.

Firstly, the NAD is a good 7-10lbs heavier than the Anthem so this may be an indication that the NAD has a better amp but not necessarily so.

Also, there was a user review on Crutchfield noting that there were HDMI troubles with the NAD, and I can safely say that my unit does not have any issues. I did do an immediate update right after I powered on the unit. I played some 4k/UHD movies on my Nvidia Shield and streamed some Netflix and Amazon HDR content fine. In fact, I say the HDMI connect on the NAD is better than the Anthem as I would get constant flickering on the Anthem.

The user-ability and menu on the Anthem is much better than the NAD. It is much easier to navigate around on the Anthem and everything seems much more logical. The NAD isnt bad tho and I think it is still better than the Marantz I previously owned. The NAD is also missing an ethernet port so any updates will have to be done over WIFI. I cant fathom why NAD omitted an ethernet port!

Finally, the room correction software clearly makes a huge difference. I have to try to run my speakers on the Anthem w/o ARC to see how they sound, but so far without any room correction on the NAD, the Anthem is clearly better. The bass from my sub (Rythmik L22) is so much more refine and distinct on the Anthem w/ room correction than the NAD without. The supplied mic NAD provides with the unit is inferior to the one on the Anthem. Hoping I can use my umik-1. Hopefully NAD comes through and correctly implement DIRAC. I bought my unit from Crutchfield so I have 60 days to test it and hopefully NAD can deliver the goods.

Those are my early impressions and I hope it helps.
It sure does help and thank you for taking the time to respond!

Basically it looks like I can't go wrong and propably down to a matter of preference. As this will be mostly home theatre I'll just look for the one with the most capabilities.

I've also come to understand from readers these forums that a little subwoofer will take a lot of pressure off the receiver and mitigate some of my "power" concerns

Yup. I ran a little emotiva s8 subwoofer with my ls50w, and it gave it that extra kick. It is perfect for those living in an apartment. It's tiny and very light which makes moving them around a breeze.

I upgraded to a Rythmik l22 and while much more substantial, the little s8 was sufficient. I actually miss the s8 as the placement options was plentiful.

I had previously thought the LS50s were amazing speakers for jazz and baroque music, but not well suited to large orchestrations. Yesterday I installed an Ayre KX-5 Twenty preamp to use with my VX-5 Twenty amp. It changed that thought. The new preamp makes the LS50s sing in a way I'd never heard before, with great detail and sense of transparency. The LS50s are crossed at 100 Hz to a pair of Velodyne HGS-10 subs. Now it may be argued that using electronics with an MSRP of more than $20K with $1500 speakers is crazy, but the LS50s reveal and reward exceptional electronics. They deserve the best you can provide.

Couldn't agree more. When I switched from my Anthem receiver to my Wyred4Sound STP-SE preamp for 2 channel music, it was a big upgrade. The W4S preamp provided a huge increase in perceived soundstage height, width and depth. Also transparency, detail, texture, musicality, PRAT.

Ordered a couple of W4S mAMPs for my KEFs today. I struggled back and forth between them and a Rogue Atlas tube amp. Even found a Rogue dealer 2 hours from home that would of offered the same finance deal as Amazon did with the mAMPs. Called Wyred4Sound and CCed the extra $250 for the mAMP binding post and wire upgrade.

But really needed the lack of heat and power savings of the class D over the tubes. Instead of waiting for tubes to warm up, I will just leave the mAMPs on 24/7, and they will be ready to go. I imagine they will be fine.

How are those W4S mAMPs sounding?

I love my W4S STP-SE preamp with my LS50's, but I also love my tube-hybrid Blue Circle power amp.

Getting the best sound from the mains. I just wish they had included an output to enable using their DAC/wifi with other amps. So I guess I am keeping my powder dry for now. Hoping for some sale activity or improvements in the next 6-8 months. I think I'll probably make a move after the first of the year.

Chris,

Have you upgraded to LS50w in your surround system? I'm very interested in doing this. I have a pair of the LS50w in use on my computer. I love how buttery smooth they sound. I'm impressed and surprised by their sound every time I fire them up. I had previously owned the LS50 (passive) and the LS50w blows them away IMHO compared to the modest equipment I had (Onkyo and Marantz receivers and Emotiva amp) powering the LS50. Not that the LS50 were slouches by any stretch, just my take on the LS50w. My goal would be to run the LS50w as mains and maybe a center and LS50 as rears. I'd be replacing DefTech Mythos STs, CS8080 and Mythos Ones in the rear.

Any thoughts or ideas are certainly welcome.

Well I temporarily hooked them up to my existing setup just to see if they worked , ran for a couple hours and as is they are very impressive. The treble may of been a touch spitty, but W4S (and the reviews I have read) states that this will improve in a couple hundred hours.

Honestly it still sounded better as is then some other (well broken in) amps I have had on the KEFs. The resolution was much more clean and detailed than the previous amp, a Yamaha pro audio model.The Yamaha worked for me as it is overly warm, but was non-fatiguing.

I am doing an amp relocation (in a different rack) and recabling, to shorten the speaker and interconnect cables. Hopefully will be finished some time this week so I can start the break-in. That's the only downside to these class D amps, one needs to be patient.

Another one of the reasons I went with this amp is try them on a pair of Magnepans I have, so I can have a two brand speaker setup, depending on the urge. Can't do that with a pair of KEF actives.

I'm using a NuForce preamp with the mAMPs, seems like it is a fine match. I have read that W4S's preamps are great performers, so that is a future upgrade path. Or maybe a tube preamp.

Xip Xero: No I haven't pulled the trigger on the LS50w speakers yet. I plan on it as soon as I can after I get through a relocation we're in the process of starting which is delaying my HT plans for a while. I expect I'll take advantage of a year end clearance to bring them into the system. I intend to do a similar configuration as you've outlined, depending on the room. Wireless as mains, with 5 LS50 passives and a pair of Kef 102 refs in either a 5.2.2, or 7.2. I might even un-retire my M&K dipoles and put them in the mix to try a full Atmos setup. I would have the Yamaha drive 9 channels plus the wireless mains giving 11 channels for movies. It all depends on the new place, which we have not found yet, but the move is committed. Fun going forward is inevitable.
Not sure this helps much, but I recently heard the LS50w set at length and I continue to like what I hear very much. I think the passive speakers really require significant power and high current. I will keep mine, they sound superb to me. Having them driven by Kef designed power just really makes sense, so adding them is really a no brainer.

Good luck with your setup. Keep us posted on your system as it develops.

Cheers, Chris
