Mesanovic CDM65 Studio Monitor Review

I haven’t owned these but their bigger brother the RTM10 are super creamers extremely neutral with real extension.
We had the GGNTKT M1s in the same period and the two made an interesting comparison.

A good comparison of constant directivity (M1) vs constantly increasing directivity(RTM10), since both do their thing so well.

Thank you, you are right, I had overseen see that there were two options in the spinorama, now it is more comparable to the D&D from 250 Hz and above (although the D&D cardioid goes lower) :View attachment 414620

DD controls directivity lower because of larger baffle, larger drivers, presence of side vents and rear-mounting woofers.

But what the Mesanovic does very well is bringing the fundamental principle down to a much lower price range and smaller form factor with still significant directivity control.

And what I would also highlight is that it offers a very good monopole mode. It's basically designed from the ground up to be both a good monopole in its own right but also provide meaningful cardioid with just a change in DSP parameters.
That, other than the lower price, sets it apart from Kii, GGNTKT, Geithain and DD. The flexibility with a monopole DI match that is also very good:

To have baffle size, driver configuration and driver placement optimised to give both meaningful cardioid and good monopole performance is remarkable.

KH 150's sound power response is horrible compared to its competitors.

Another problem with KH 150s is that they do not have a great sound power response for farfield listening. (sound power is the highest determining factor for farfield listening sound quality) While the KH 150s can sound great in nearfield settings, their sound power is too non-linear for farfield use.

Yet no mention of this in Amir's glowing KH150 review. What gives?

Predicted-far field response is still quite good:

Normalized graphs make it easier to see what’s really going on in measurements. Notice how uneven the sound power response is compared to a smooth linear roll off.

Take another look at the sound power response: looking at it on its own shows how non-linear it is. Ideally, it should roll off smoothly at a steady rate from 200 Hz to 20 kHz. I like -1.2 dB per octave, though some people think -1.0 dB is better. Either way, it’s a long way from that ideal right now.

Actually, I agree with this. It rolls off too steeply in the mids (300-~1.5k it appears to slope closer to 3dB/oct which is very steep!), it has a hole around the crossover point, and then the WG being a CD design means it basically flattens out (a hair under 1dB/oct for a rough estimate) above that. It averages out okay - but from people who don't like it, they either hear it as kinda scooped in the presence region, or as "dark and also harsh" (which is how I hear it).

The CDM65 on the other hand has a much smoother handoff to the tweeter, remarkably so in fact for a non-coax effectively two way design, and the SP slope is much more linear (not perfect, mind, but very good).

I am just very picky with value ever since picking up day trading

If you get really great at day trading, or better still at investing, then your time will be too valuable to read this forum, and you’ll be best off seeking advice from a high markup vendor and buying what they tell you to buy …
