I think the MP150 has been updated following the S150. At least it's gone from independent tweeter waveguides to the single unit like the S150. I really have no idea on other models, but I suspect that at least some of them have seen updates over the years.

I'm considering the IW150T as surround back speakers if I go from 5.1.4 to 7.1.4 so they don't get in the way at the back of the room as on walls would. I run S150T side surrounds, MP150 x 4 for the Atmos channels and MPS300 LCR in 5.1.4 at the moment. Going for IW150T would keep all my surround and Atmos channels consistent.

I did consider swapping the side surrounds for S300T and move the S150T to the rear, but cost and the fact that the S150T would get in the way a bit at the back count against that option. Another option is the IW150 non Tripole, but that option is approx 50% more expensive than the new IW150T and I don't think is justified for surround backs. I might even 'cheap out' and go for IW85 as I think they have the same drivers as the 'front' of my S150T on walls, but have to do some testing using borrowed speakers from my second system (M&K K5 and K4).

I am from the UK. I have a different username on the UK AVForums site. It is Zamwessell. I am currently thinking of upgrading all my speakers to MK. S300s for the front LCR. IW150T for sides,rear and ceiling duties in a 7.1.4 configuration for Atmos. I will have the option to add wides making it a 9.1.4. My room is fairly small, W 2.4m x L 5.5m x H 2.3m so i probably do not need to add wides if using tripoles. Also considering S150s for front LCR but i keep yearning for the 300s.

I only went from MP150 for the LCR to MPS300 for the LCR because my dealer was selling his demo LCR set at a very good price. The MPS300 are very good, plus I changed my room so I'm sat a bit further away than I was with the MP150 as LCR, so it helps having the extra headroom. I run them from an Arcam P7 power amp (230 watts/4ohms), so they can hit reference at my MLP, not that I tend to listen that loud typically.


Otherwise I would have probably gone for some IW85 as Atmos channels rather than buy a 4th MP150 and use them as Atmos channels (I had to be creative mounting them, but it works, assuming you've seen my build thread over there ).

I will have a look.

RE: pg 158, thank you Audiofan1 about the upside down configuration you are running.

My M&K sub is 23" high, but on two stack of 8-1/2 x 11 paper reams on it's back is 19" high.

The 4" lower height when used in the center between the main speakers opens up the soundstage because of fewer reflections off the cabinet.

It sounds great.

Bottom firing woofer pointed towards me, front firing woofer pointed towards ceiling.

And as far as "The M&K" sound goes, the latest speaker claimed to be a "game changer" Bayz audio copies the push push - pull pull double driver concept.

For those also interested in the off-axis response curves for MK current speakers (ex to help with speaker placement).

I heard back from M&K and they said they cannot publish this data. They said the speaker is compliant and within THX specs for off axis response, but no one is allowed to report what thx specs are due to NDAs

The great non-answer answer. The speaker in question (the MP150) is not even THX certified. Even if we were talking about a THX certified S150, revealing the data for it doesn't necessarily reveal THX's specs since it likely exceeds the specs at least in some regards. I wouldn't worry about it too much. There will likely be some high frequency roll-off off-axis, but I wouldn't expect it to be significant enough to cause any problems. Toe-in if it's reasonable and practical, otherwise don't worry about it. They are designed to be mounted without toe-in.
