You don't necessary need a subwoofer, a lot of it has to do with your room and the type of music you listen to

I originally thought I need a sub too with LS50 but in the end, I rarely turns on my Martin Logan Depth as the LS50 has enough bass for me for the type of music I listen to after room gain..

As far as Sierra-2, it was on my list too but I could not find a pair of Sierra-2 to listen to and I can't stomach spending close to $100 for 2 way shipping just so I can demo the speakers, however, I don't think they are better than LS50, if anything, from my research, I think Sierra-2 and LS50 are in the same league, both price and performance wise and it will depend on your personal preference to the sound and the look
I have not listened to them yet, I am going to take a look at them on Saturday. I don't listen to music with too much bass either but I guess it's nice to have that option.

LS50s need a sub. They sound like a poor man's Blade II when used with a high quality sub. I will be adding a Velodyne DD10 plus to mine.

I looked through your thread and you have a very nice setup. Are you running them without a sub right now?

Thanks. Yes, no sub since I purchased them a couple years back. I listen to pretty much everything and some music would definitely benefit from having a sub with these, no doubt.

I thought you ended up uing B&W AM-1 for the atoms speaker with your LS50?

If possible, could you share some pictures of you LS50 theater room setup?

Howdy,

What are you guys using to drive these for rears? AVR or separate amp?

I'm ready to complete my surround set-up. Wanted to wait until I had my front all set and a bit of time under my belt.

Was going back and forth between Dipole from R series and the LS50. I have decided the best match for me is LS50.

I'm using mono amps for front three. Will use a small footprint stero amp for rears.

Will be Marantz 7025, Cambridge Audio Azur 651W or Parasound Halo A23. No experience with these amps and since its rears will just pick one. Leaning towards the Cambridge Audio due to the fact I have owned their blu-ray player once and it was superb. These were picked for price, size and xlr connection. I want to use cables I already have.

Just gauging what others are using. I know it's rears but if the LS50s are like my KEF mains they do much better with some juice.

I've used a Parasound A23 to drive a pair of LS50s, but I think I prefer the sound when a Proceed Amp 2 is driving them. I'm using the amp with direct HDMI connection to an Oppo 95, so the audio trigger capability of the A23 is an advantage -- I too often forget to turn off the Amp 2.

I recently replaced a Proceed HPA 3 (3 X 500 watts into 4Ωs) with Parasound JC 1 amps (800 watts into 4Ωs) to drive my KEF 107/2s. The difference in sound is striking, especially LF extension and detail. Each JC 1 is as large as the HPA 3, so I suspect the difference in sound may be attributable to current delivery. I suppose it also could be special synergy between the JC 2 BP preamp and JC 1 amps. Bottom line: KEF 107/2s, even though rated as 90 dB sensitive, do better with lots of juice.

Very nice DB. Yes, I'm using Simaudio mono 400m x 3 for my front. The match-up has been what I hoped and beyond.

This is for the rears and don't want to go overboard. I think I will order the Cambridge and give it a whirl. Toroidal xformers , xlr, size will slide right into my rack.

Edit: ordered the Cambridge Audio to try.

Anybody think I will have a good match using a single LS50 as center speaker and have Kef reference inwall Ci5160RL for L/R? Setup includes 120" projector screen with JL sub.

I am about a month away from completion of new room (16x20 before framing).
tractng,

Any reason for not have another Ci5160RL for the center speaker? It would make the front sound stage seamless with 3 identical speakers for front left, center and front right?

Use the LS50 for surrounds or surround backs as these tend to be more near field and this is what the LS50 has been specifically designed for - near field monitors.

I need to built a cabinet right in the middle to house the equipment. Maybe leave the middle of cabinet open and put the center inwall there.

tractng,

If you can have the center speaker in the middle of the cabinet and hence the middle of screen, it would be better. Can you re-design your cabinet such that it's a baffle wall for the front sound stage? This would be is close to ideal.

Edit: Reasons for having a baffle wall is explained here: http://www.acousticfrontiers.com/2013322baffle-walls/

Speakers inside cupboards or surrounded with paneling will sound awful. The Kefs are rear ported as well which makes it worse

Pivetta Opera
Bose Jewel speakers.

I am thinking of something like this.

http://www.kef.com/html/us/showroom/...ges/index.html

Building a false wall out deep enough for a LCD/TV and electric screen (probably about 9" depth total). For the cabinet, about 30" inch depth.

L/R = Ci5160RL (the false wall on each side toe in a little bit)
C = Ci3160RL (will be inside the cabinet)
Sub = JL F113 will slide inside the slot made for it so everything sits flush

Any good deals on the LS50s going on right now? (Black)

I'm thinking of trying out a pair as a replacement for my wide and surround ML EFX. I feel the design of the EFX is inherently flawed because it is placing an ESL panel so close to the wall (3-4"). Hoping the LS50 will have a similar sound signature without all the early reflection issues.

Hi tractng,

Would it be possible to move the center speaker (Ci3160RL) to just below the LCD TV? This way, it would be aligned with the front left and front right speakers and better than having it on the floor. Also would it be possible to move forward the LCD TV so that it is also aligned with the front left and front right speakers? This would complete the baffle wall. The side benefit is that the screen can than be wider and fill up the entire wall from left to right.

With the cabinets at the floor, the sub needs careful placement. Perhaps consider having the sub above the cabinets and in between the center speaker to either the front left or front right speaker. It could be integrated into the baffle wall. If you have the means, get a second sub as it'll help out tame the room modes.

Behind the baffle wall, might want to consider some acoustic absorption material such as OC 703 that can be used to control the back reflections from the front sound stage. Bass absorbers are going to be needed at the room corners to control ringing. Also look at 1st reflections off the ceiling and side walls. Back wall quadratic diffusers will make the room sounder bigger and more pleasant.

All this stuff can make one's head spin. Might also want to contact Nyal Mellor for advise on your theater setup as he is an expert on room acoustics and video setup. Nyal can give you much better advise than me. Nyal contact details are available on the acoustic frontiers website.

Been looking at these speakers to start a 2.0 music setup. Would a Creek 50a or Marantz PM7005 be sufficient to drive these or do the LS50's need more power?? I listen to a lot of vocals and rock/alternative music if that helps. Would like to keep the amp purchase to less than $1500.

Add a sub with any of the 3 amps above to pair with LS50 and you will have a very high value and high performance stereo setup

FWIW the KEF store in Hong Kong hooks the LS50s with the Marantz PM7005 for 2.0 music demos. For vocals that should be enough, if you need alot of bass with rock music then adding a sub would be useful.

Power of the amp really depends on the size of your room and distance to the MLP. One of the strengths of the LS50 is that they work well even with relatively inexpensive amps. Anyway, integrated 2-ch amps are relatively inexpensive, and the Marantz PM series would be a good choice.
