KEF LS50 Owners - Page 10

post #271 of 652
new to this forum.just want to share,i paired my ls50 with rel t5 sub bass system.I set the crossover of the Rel at 40hz and volume at 12 o'clock. By using this setup,the rel only supplement the freq below 40hz down to 30hz and ls50 still handle all the freq its capable of.The input fed to rel are direct via amplifier mains speaker output.The best setup for music!

Ls50 owners can chime in on this but I don't think the ls50 plays down to 40hz. I think most people here seem to be crossing closer to 60-80hz. Congrats though!

should be fine, because frequecies above 40 and below -3db of ls50 will get intgreted.
post #274 of 652
hi, to my ears, and in my room, 40-45hz is just nice..midrange not smeared by bass and the details still there. what i hear when i turn on the Rel is the jazz still jazz(rel don't add anything if no musical instrument below 40hz) but black eyed peas turns to be "blacker"eyed peas tongue.gif(bass tauter and the seat start to vibrate-Rel start to kick-ins).if i turn the Rel crossover to 60hz made the music sounded muddy.i believe ls50 with matching amps/room size can go below 50hz.hehe

I guess if running LS50s full range and using the sub's crossover to cut the high end it would be different than an AVR to split them. There will be frequencies above the setting that make it through.

I thought it was always better to set the sub at the highest cross over and the speakers crossed over in the pore/pro? Now I am confused, which is it?
post #277 of 652
if i'm not mistaken, there are 3 config for integrating the sub woofer to system.1st one is by using AVR as processor/crossover to split the signal between subs and mains speaker(LFE or .1 perhaps for stereo amp).2nd is by using hi pass filter crossover built in at sub, sub have speaker out which means the mains speaker low freq are filtered out by sub crossover setting(velodyne,Svs etc.).the 3rd which what i'm using now is pioneered by Rel(hi level input) where the mains handle full range, and subwoofer only supplement the lowest freq.i like the 3rd idea, which is i really like the bass coming from ls50 and its a waste if use 1 and 2nd config.Most of the time i listened without turn on the Rel, only if the music material need more bass than only i turn it on.I can call it flexibility..best of both world configuration tongue.gif

I appreciate the input on the use of the REL T5 because that is exactly the sub I'm looking at purchasing.

So I'm curious what kind of amplification all you KEF LS50 owners are using? I use the NAD C390DD Direct Digital Amp in a two-channel setup connected to a Tivo, Sonos Connect, Apple TV and Oppo BDP-83. The C390DD blows my mind and is a perfect fit for the very revealing LS50s.

Also, looking for any great recommendations on speaker stands. Right now I'm using some very old Lovan 28" stands but I'd love to upgrade to something better and more decor friendly.

How's it sound with prima Luna? Which one is it?

Hi I have been thinking of picking up a pair of these from a local dealer but was wondering if my old pioneer sx-1250 would be able to drive them right

I use to have a pair and was using a NAD 326 bee and it was only 50wpc . They sounded great !

I was wondering if anyone has had experience with these amps for the KEF LS50

 

So I have been looking at the following but it is hard to evaluate just on specs as we all know!
 
Musical Fidelity M1PWR
 
- Peachtree Audio 220
 
- Marantz MM7025
 
Parasound Halo A21 Two-Channel Amplifier

Not sure about others but the A21 would be my choice.

Do you know if it is fully differential balanced?

post #285 of 652
It is not. If you need that may want to consider the ATI AT2002.

I heard Prima Luna tube integrated with the LS-50 whoa very nice smile.gif

Just wanted to update...I ditched the Benchmark DAC2 HGC / Parasound Halo A23 combo for a McIntosh MA6300 / Schiit Gungnir combo and all I can say is they complement the LS50s very nicely. It's also been easier to integrate a sub but I'm finding that I don't need it much.

Very cool, I am thinking about getting tube amps as well!

Just upgraded my amp from Nad c326BEE to creek evolution 50a. improved the midband clarity over the nad, bass much fuller and sweeter treble.the Nad i have has some kind of edginess and quite harsh on some music.
Can demo this amp before going up the ladder.it's really that good.
refer link for my reviews on other forum(if admin don't mind cool.gif )

I have a rogue sphinx otw to power the ls50's on sanus uf sands. I'll let y'all know how they work together soon.

A question for those operating their LS50's as center speakers and having them on their side (because of height restrictions in their cabinet) - Do you notice much difference in dispersion compared to you L-R LS50's that are correctly oriented?

My center LS50 is sideways. Because of its semi enclosed
location I had to experiment with the different port plugs.
This took out a minor bit "chestiness".

I have experimented with my center both horizontal and vertical, no difference at all. I also have mine in tight conditions,and I have both port holes filled. Sounds wonderful.

Anyone have the port plugged, how does the sound change other than less bass?

Mine are completely plugged due to how close the are to my back wall. No discernible difference in sound. Bass is a bit lower. However,I'm also using a sub.

Yesterday I had a good dealer demo of the KEF LS-50 Speakers. This was the 3rd location where I heard these speakers (it took some travel to be able to hear these in three locations), as I like to hear what I am considering in more than one showroom. I thought that those considering these speakers would be interested in my experience.

The first time I heard the LS50 was a couple of months ago. The dealer set this up in a room that was loaded with other equipment scattered about the room. The initial amplifier chosen was an Anthem MRX-700. While sounding OK, the overall sound did not do much for me. He than hooked up a Parasound Halo Series Pre and A21 amplifier. This sounded better but the L-R never seemed balanced and it appeared that the room was having much effect on the demo. I left the demo wanting to hear more in a different environment though this little speaker did impress me.

I got my chance a couple of weeks later for my second demo of the LS50 in two different dealer rooms. This time the rooms were much better, but in both the amplifiers used were beyond anything I could afford. The sound was good in both rooms though one room was much better than the other. I left with a very positive impression of these speakers and they are now on my short list where all other speakers are Tower formats.

Yesterdays 3rd demo was the best and lasted over three hours. The room was OK and more representative of what my room was like than the previous demos. The initial RECEIVER provided was the Denon AVR-4520. I listened first to the speakers alone (all demos were in Stereo) and later with a Sub. I provided my own music for all of these demos. This relatively low cost receiver sounded better than any of the previous LS-50 demos. All characteristics of these speakers were good in all respects including the bottom end. When we changed the setting to add the sub, we found that the best sounding crossover point was 60 Hz and it sounded better than at 80 Hz that the speaker easily carried. I cannot believe how low these small speakers can go and I would not hesitate to use these without a sub in a music only system. But with this receiver, I think that using a sub would take the load off of both the speaker and receiver, especially in a mixed use Home Theater setup. For those trying to keep their costs down, it appears that the LS50's (5) with Denon 4520 and a good sub is a reasonable choice for a Home Theater at low to moderate sound levels. The bonus is a great center speaker in the LS50.

This same dealer had a number of Parasound amplifiers in the store including a pair of JC-1 Mono Blocks next to the LS-50's so I asked it we could hook these up. We continued to use the 4520 as a Pre. Simply.... the sound was amazing. I had never heard sound like this out of any 5 1/4" speaker and (without side by side comparison) rivaled what I remembered from any previous demo including Tower speakers, except for possible the extreme low end (Below 60Hz) . And this was without any SUB. The sound was much more open and full bodied and it totally made these speakers disappear into the room. It never sounded like we were straining these speakers though I did not drive them that hard, but it was to a reasonably loud level.

So what got driven into me on this demo (and has often been said on various forum discussions) is that these speaker will sound as good as the associated equipment used with it. So for me this gives me a high and low price range of associated equipment on my short list for this future 5.1 system. Low would be the equivalent of the 4520 WITH SUB's and the high would be a good processor (including the 4520) with Parasound JC1 and Subs, which I cannot afford. Fortunately I still have time to make a decision and find a midpoint plus CEDIA is right around the corner. My real recommendation to all who are interested in these speakers is to try to get a listen to these in more than one physical location, and do listen to them with a variety of different electronics in the same room.
