When I configure my processor for S-150Ts should I set them to small or large?

If you have a sub, go with Small. It will properly set the crossover point to send the lower frequencies to the sub instead of damaging the 150's.

yes I agree with post above but I would sent it to small anyway crossing them over at say 90 or 80 Hertz I wouldn't want to damage those nice speakers myself if I owned them...

The new MK Sound make fabulous speakers that easily outperform the MK of old,which were seriously great speakers anyway.

I ran my S150T's as small at 100hz as I do with my S300T's.

The new company is certainly making great speakers thus far. The S300s and matching surrounds were amazing while I had them in my house.

They are indeed. I'm running the MPS300's and S300T's with a Sub1. The Sub1 is being replaced tomorrow for a pair of the new MK V12 subs which will be L&R front corner loaded for s better in room response.

Very nice setup. I really loved the X12 subwoofer a lot, but with a freshman at UCLA this year there was no way my wife would let me buy a completely new speaker upgrade. Frankly, I would kill myself if I made that call!

Enjoy the new subs!

I have been getting the itch to upgrade and had been listening to several speakers around my area. I have had M&K 150 and now run M&K 5000. I even for fun bought a new JBL studio series that is a horn system to play around with.

I got the center channel before the mains and hooked it up just to see. Any comparison to the M&K was embarrassing. Just like I have felt before M&K do dialing and detail so well. Cancelled the entire order and am back to keeping my M&K. I am wondering how much I would have to spend to see a improvement. I am big into detail and M&K do it so well.

I have thought about buying a set of 150's and comparing it to the 5000. I currently run two SVS PB13 but don't love them. I actually sometimes miss the tightness of the M&K 350 sub I had. Very detailed.

Well It looks like the M&K are here for a while. Hey more money to upgrade something else in the theater Any of my fellow M&K brothers have the same experience. At what price are we going to see something superior.

The new 150mk2's are more detailed and smoother than the originals and the 300 series are a big step up in performance.

Ive listened to many other speaker brands and none have that MK detail. I am now installing a Lyngdorf TDAi 2170 integrated amp into my AV system to run 2.2 channel music with my MK MPS300's. This stereo set up within my AV system will better many so called high end 2 channel set ups costing many many $1000's more and it's still an AV system.

Once I'm finished installing I will post pics later this week.

There's a pretty big improvement in the S300's midrange over the S150s. There soundstage is deeper and more layered, if I recall.

Did you hear already the Quested speakers?
I read also a lot of positive things about the Quested speakers. They are also in the same price range then the MK S300.

I agree 100% with this. They are also fantastic for 2 channel music

Tweeter orientation

Former M&K MPS 2510P/2525P owner here.






I have considered getting some M&K S-150/S-150P/MPS 2510/MPS 2510P's to utilize as surrounds. As people know, however, they made a left/center channel with tweeters on the left, and a right channel with tweeters on the right.


How important is tweeter orientation if utilize the speakers as surrounds? My gut instinct tells me that the 2 rear surrounds should be oriented like a left and right channel.

Instinctively (and esthetically) you would think that mirror pair is an absolute must, be it front or surround. Ken of course always espoused mirror pairs, but the whole genius of the iconic driver layout is that its as close as anyone has ever gotten to a point source while using no less than FIVE transducers. Think about it: if mirror image L/R was THAT big a deal, then how could a random one have ever worked properly as a center?

All that to say that if you are buying new, of course get a mirror pair but if, hypothetically, someone gave me two "lefts" to use as surrounds....I would and not think about it. Besides which, unless they are the somewhat less common angled baffle cabinets, all you have to do to turn a left into a right (or vice versa) is turn it upside down.

Tripoles on the other hand are a completely different issue. Those NEED to be L/R pairs in order for the phasing of their dipole components to work correctly together.

Thanks

Thanks for responding Sunsanvil. I have read in the past though that dialing in the left and right channel speakers is not simply plug-and-play. Meaning, that they needed to be dialed in order to properly coordinate with a system. Having the tweeters facing the correct direction would be helpful. You do have a point about the center channel, as there is a lot of activity in the center during movie playback.

The only "dialing in" of note which needs to be done on 150/2510s (as compared to other speakers) is vertical aiming due to their directivity in that axis. M&K used to even sell a small laser which would stick to the front of the speaker via magnet, and allow very precise aiming in that axis. The relevance of this can be tested fairly easily (assuming they are roughly aimed at your head while seated): Listen to some balanced material and while its playing....stand up. Even a novice will hear a notable drop in treble!

There used to be some debate as to whether the L/Rs should be positioned such that the tweeters are on the inside or outside, the general consensus being on the outside unless they are miles apart, but here again in retrospect those were somewhat silly, or at least extraordinarily nitpiky, discussions. Again, consider the center speaker of a 150/2510 array: IF the side on which the tweeters sit mattered that much, then the person on one side of the couch would hear radically different sound from their companion on the other side...which of course is nonsense. Either side of the couch gets the same excellent sound with these speakers because they were designed and indeed perform with tremendously wide horizontal dispersion.

Verticial dispersion

I owned my M&K's for about 8 years and I have no recollection of experiencing issues while sitting vs. standing up or walking around in my room. In any event, any idea what the vertical dispersion pattern of the 150's are? The phenomenon you are describing would suggest to me that the vertical dispersion is fairly narrow.

How far away from them do you sit (and being 2510's, what setting are you using)? The further away, the wider the cone is. Try starting from, say, <6 feet from them.

It is very narrow by express design (and requirement by THX). The three tweeters are not a simple line array, the top and bottom receiving a slightly different signal from the crossover as compared to the middle "main" tweeter. In concert with the foam appliqués the result is a reduction/cancellation off axis vertically (yet sum perfectly on axis/horizontally)....hence narrow dispersion in the vertical. There is also stuff going on with the woofers and between the tweeters and woofers but that's too much to get into here.

IIRC from conversations with Chuck Back many years ago, the narrowest of the family will be the original S150THX. The MPS-2510 in its "narrow" setting will be similar, in its "wide" setting less so though still somewhat constrained (intended mainly for when they are VERY close to the listener, such as at a mixing console). In "stacked" mode the MPS-2510's tweeters do in fact form a line array (meant only for when stacking multiple units). The MP150s, being by their wall-mount nature not "aimable" at all, had the widest vertical dispersion of all the "3-tweeter/2-mid" M&Ks so that they could be placed on-wall above/below a screen (or high on a wall for surrounds) without issue. I cant recall where the S150-Tripole fell but I think it was on the wider side of things.

Here my memory gets a little fuzzy but I seem to remember that "late model" S150THXs (before the change of hands) were not as narrow in the vertical as the original, probably similar to the 2510's "wide" setting. You know you have a late model if the foam appliqués are all strips as on the MPS-2510 as oppose to the inner two being squares. I'm not 100% sure of the timing by I believe that change coincided with them using the TL tweeter from the 2510 as well.

Past set-up

Thanks for the informative posts Sunsanvil!


I had the M&K MPS 2510p's for the mains about 8-10 feet away when I had it set up in a 12 x 18 foot family room. The center channel was on top of a 65" widescreen Mitsubishi TV, so it was higher than the left and right channels. The MPS 2525P's for the side surrounds were bracket mounted on the walls and they were about 5 feet away from center listening position on a couch. The rear surrounds were mounted on top of tall shelves and were about 6-7 feet away from listening position.


I recall my favorite movie back then being the opening battle scene in Gladiator. Back then I had a MPS 5410 and when the big barbarian hit the shield with his huge hammer it was awesome! I also loved when the Romans shot the fire balls into the trees. The Matrix also sounded fantastic with the system!
