In my point of view the reasons are:
This is a flawed idea for the reason that it assumes all brands are after ultimate performance, and also assumes all brands have the same idea of what "ultimate performance" is. Don't forget that you can buy single-driver speakers for 6-digit sums of money. In this forum you'd be hard pressed to find anyone considering that optimal, but around the web there are plenty of people who swear by e.g. Voxativ.
Why don't all watch manufacturers just make smart watches, or all car manufacturers make electric cars?
This! It changes now with the upcoming of ready to use class D power amplfier modules. An analog x-over is not that difficult to design, and adding DSP is possible due to easy to program small computer modules like the Raspberry Pi with attached DACs. You still need expertise in DSP per se of course.
I guess with GLM making the necessary corrections it doesn't matter - but I'm wondering how much of that placement is simply because the non-parallel walls on all sides permits flexibility of sub placement? Generally, in quadrilateral rooms, having all subs on one wall is not recommended, but then that's what GLM is there for!Genelec themselves disagrees with you.
A Visit to Genelec USA (Natick MA)
A Visit to Genelec USA (Natick MA) Having read about Genelec loudspeakers for some time, I tangentially came across a post in a Facebook group about room acoustics from the architectural firm (https://www.fmdesign.com/) that designed the Genelec Experience Center in Natick, MA, which was...
GLM is just an EQ. There are various other EQ systems available for systems and subwoofers. Just EQ your system to balance out your room modes instead of worrying subwoofer placement.
My only concern are the deep nulls of room modes which EQ cannot properly address, and only by moving the subwoofer can I shift that null elsewhere in the room, away from my MLP - I may end up introducing a peak to my MLP but that's much preferable to EQ.
Isn't MLP an EQ? You can create any type of FR via an EQ, including very narrow (high Q) peaks and dips.
A deep dip in a room FR is the result of cancelling waves and cannot be corrected by EQ, since both waves (the direct and the reflected) get louder and still cancel each other out.
How does MLP solves that problem?
Because the frequency response is both speaker and listening position dependent.
Thank you but my question was "how" does MLP correct the null(s) caused by standing waves?
No idea, ask them.
but you have first hand experience that MLP eliminated a FR null whereas an EQ couldn't?
I didn't know that and I thought it is a different type of room correction system.
And I thought the same as I didn't know the short cut ...I didn't know that and I thought it is a different type of room correction system.
This is exactly what I was describing - deep nulls from cancellation. Moving the sub around the room (or your MLP) will shift that null away from the MLP and at worse may move a peak to the MLP (which can be mitigated with EQ).
