Genelec 8351B vs Mesanovic RTM10 - AB Test Preparation

[Jason K]

In a few days, the Mesanovic RTM10 arrives.

I'm currently using Genelec 8351B and 7370A in my living room without any acoustic treatment.

There are plans for acoustic treatment soon, but the RTM10 is likely to arrive first.

I try to plan an AB test with an active 3-way speaker at a similar price point, both of which score high in preference scores and are expected.

I looked at the above thread very interestingly, and it was a reference to the test method.

I am trying to construct a more complicated but similar signal path.

Network Player
-> Minidsp Nanodigi 2x8B digital in (8ch)
-> 1,2ch-8351B Digital in
-> 3,4ch-ADI2 Pro Digital in for RTM10 Analog in
-> 5,6ch-7370A Digital in

Nanodigi has 4 presets.
Presets 1 and 2 will be the comparison between the 8351B and the RTM10 alone, while Presets 3 and 4 will be the comparison including the subwoofer.
Also, all presets will be corrected to a consistent curve in the bass response.


As compared to Salon 2, I am not confident of setting the two pairs vertically, so I plan on setting AB-AB.

For the details, the delay and level of the difference in distance will be corrected for the speaker getting closer to the listening position.

I haven't tried it yet, but I think it will be okay.

Please leave any additional comments.

Thanks, looking forward to this!

I'm excited to see how the results will come out!

RTM10 is finally arrived.
What a huge box!
Tomorrow I’ll upload the measurements with 8351B.
Thanks Deni.

I like your stands, I have mine on a four pillar design which is solid but not particularly elegant,

Great serial number on the back there!

That’s K&M 26720. Available of height control is why I choose it.

Very early number!

Do you have GLM?

Looking forward to this test! The Mesanovic speaker is a very interesting design, I think.

You can just send the loser to me.

Yes I have.

I agree! There are many of DSP speakers these days, I think the RTM10 is a well-made ones of them.

The RTM looks a bit like the D&D 8c in concept. An active with high quality electronics from a small company at a relatively high price point. Like the 8c if something goes wrong 5 years from now it might not be repairable.

Oh I have to delay the competition to see them more haha.

Do they couldn’t be repairable after 5 years?

I brought some measurements.
They were in living room (about 8.6 x 3.7x 2.4m).
And listening distance from the speakers is about 3m. I played the pink noise 500 to 2kHz, matched the level to 85dB at listening position. And sweeped.
Though It looks like there were some room mode gains, but the RTM10’s bass extention is quite deep.

I always wonder how about the distortion in bass range? Some kind of speakers, like with DSP, sealed cabinet, deep sub bass extention often have high level of distortion. I once saw the even D&D 8C has 10% distortion at sub bass at 90dB in room.

RTM10 also coudn’t be completly away with them, but quite good.

The bass range is 90~95dB in room.
I think the peak 2nd distortion at 30Hz is in room error like rattle noise.

Generally 8351B has low distortion than RTM10, But If 8351B is sealed cabinet, I think the RTM10
Will be better. And RTM10 has low distortion at high order harmonics than 8351B at 30~40Hz (port noise?) and 100~200Hz.

Above bass is quite good each other.

Here are the nomalized plots.
Overall, they are under 5% distortion.
And the RTM10’s 3rd harmonics is very low enough. 3rd is can be heard easily more than 2nd. It relative with cliping.

The parts are proprietary and the company could go broke, or the suppliers could go broke. It's one of the main reasons a lot of people are wary of high end active speakers. If you have a pair of expensive passive speakers and your amplifier goes bad, you can always buy another one.

I understand.
I don't know if there was a case yet, but it could be considered a risk.

Plus a lot of these companies like D & D and Kii have not been in business a long time. Kef's LS 50 was put out 8 years ago to commemorate the 50th anniversary of their founding. Only Genelec and possibly Neuman can claim anything nearly like that in terms of company longevity.
