A sub to go with kef ls 50 speakers

Thanks,i better try one just to know.

Dual SVS SB2000 gloss black.

I just bought a used REL Q108 MK II (can't find out why or what was improved over the MK 1, whatever that was) to stick in my window for augmenting the also sometimes window placed (used when I'm hanging out on my deck and the windows are evenly spaced so this arrangement works…I run a different power amp than my indoor mains as I have extra outputs on my preamp) KEF Q10s (had these for years and used them for near field recording as well as main speakers from time to time). The KEFs go down to around 60hz so this little sub matches fine when the driver is pointed out the window (uses the entire house wall as a baffle it seems…sounds really good for outdoors). I plan to use this little sub in my main system when the deck is snowbound, and after testing this I think it's a good match, although not really needed (the Q150 I already use provides more than enough mojo for my hifi room)…I run these subs at right around or slightly higher than what appears to be the drop off point of the main speakers…not the -3db point noted by the manufacturer, but where I hear the bass receding when using a test CD on the mains as I think a -3db spec is sort of useless in real world applications.

I heard the B&W PM1 mini-monitors with the B&W PV1D sub and it was very
impressive. However, the demo used a Classe preamp with digital crossover
that sent a high-pass signal to the mini-monitors. When you do this it opens
the mini's up to more dynamics. The PV1D as good as it sounds does not
have that high pass crossover built into the sub.

However, the new JL Audio eSub series does have a high pass crossover.
You can send a preamp output to the sub and let the sub forward a high
pass signal to the amp that drives the LS50's, opening up its power handling
and volume capability. All the JLs I've heard are fantastic, and the eSubs
have gathered some rave reviews, even from Neil Gader at TAS who says he never liked subs.

The JLs are particularly adept at blending with even the fastest main
speakers, with their huge motors and very light, rigid diaphragms. I am quite
sure the JL e110 would make a great match with your LS50s and properly
energize your listening area.

I had dual PV1D with LS50, ended up selling both...

PV1D got 1 big problem, not enough output. IT sounded WAY BETTER than internet direct subs.

My LS50s integrate well with a Velodyne HGS-10 crossed at 80 Hz. I expect well designed monitors to handle jazz and chamber music well, but the LS50s have surprised me with their ability to handle large orchestrations convincingly.

I bought the KEF R700.

Although I've since switched to the Focal SM9

id disagree with coli.
I dont see why you could even cross a sub at 100hz. the ls50 probably are flat down to 60hz and even maybe lower. it should mate great with a Rel

Coli what direction did you go

Awesome.The ls 50 puts out an incredible sound for the size of them.Iam using them in a fairly large room.Some recordings really do go 3d.I was hoping to get a bit more from them.Thanks Coli

LS50 does not integrate well with subwoofer. You'll need to cross over at like 100hz and then the quality of the sub simply can not keep up with the world class LS50.

Cost me a lot of money to learn this.. I'd suggest selling the LS50 and get the KEF floorstanders if you like the KEF sound.

What is the size of your room? Do you want sealed, ported, or either? For music, movies, or both? For music in a small to medium size room (up to say 14' X 20' or so), a single Rythmik F15 would be great, or a pair of F12's (or F15's). For movies as well, and/or a larger room, Rythmik also makes comparable ported models with slightly larger dimensions and higher output above tuning.

All Rythmik subs feature high-quality woofers driven by plate amps incorporating designer Brian Ding's patented Direct Servo-Feedback circuitry, and sound excellent. The monitor system at the well-known mastering facility Sterling Sound includes a pair of F15's, and they can afford any subs they want!

You should try the NHT B12d. I found it the most musical sub I've ever heard. It's not ported and won't slam like a sub for home theater that's ported will, however if your using it primarily for music there amazing. Well worth a listen.

Thanks,I've never ran a sub with monitors before.It would save me getting a bigger amp and full range speakers.The b@w pv1d might be a good choice too.

SVS SB-1000 worked great with the Spendor 3/5r that I used to own. They offer free shipping with a 45 day in home trial.

I bought a used REL Q150e for 200 bucks a few years ago…it's still working perfectly and I can't imagine not having it…great sub.

I'm partial to REL since they are fed the same signal the speakers see and thus integrate very well. I own a T9 which would be a good match and I believe I've seen them listed here for around $700.
