Palmer ORBIT 11 Cardioid Coaxial 3-way studio monitor (MSRP 799€/899$)

unless you have massive nulls at 300-500 hz, i dont really see why you would do that, just add a little sub if you want bass and you're good to go

might have jumped too fast on the bandwagon after seeing cardioid...i have a seriously deep 140hz null. and they dont sound good at low volumes to me, actives always seem better at lower volumes. already have subs but i generally love crossing subs at 40 and lower. always felt something missing crossing at 80 and higher. idk

Fullrange cardioids and woofers cannot correct room modes below 100Hz, but they do excite the modes less according to my experience, so equalization becomes easier and the risk of booming and decay issues persisting after equalization, is reduced.

And they help with SBIR

It's amazing if the data are true, but i still don't really see how you can manage the necessary delays to achieve the back null at something like 40 hz (8,6 meters wavelength) in a domestic room... It usualy take 2 meter or 5,6 ms delay between end fire sub PA to achieve cardioid response at this frequency).

Again, i will be happy to be wrong.

 

[Liftro]

That wouldn't be bad at all...

I suppose if I seal off the orange circle with masking tape and paint it black, I'll lose the warranty?

They are "just" cardioid from ~200hz upwards (operating range of the midrange). The woofers have nothing to do with it. The cardioid response for the midrange is archived via the slots on the sides.

Which data is saying they would achieve a back null at 40 Hz?

Provided directivity graphs show that they are completely omnidirectional below ~250-300 Hz (as expected) which equals with the coax to woofer crossover. A word "cardioid" does not automatically mean it is cardioid at all operating freqiencies, not even our W371 or 8381 manage to do that, and they are much larger products. Just look at the provided directivity/dispersion data, it is all there.

Is it just me or does the tweeter look like Dayton Epique EC30?

You post a paper about non-linear modeling of voice coil heating and then go off using linear model?

Yes, the linear model described in the paper.

And steady state at that

It's a linear transient model, not steady state. Thermal capacity would not be included in a steady-state model.

Convection cooling plays a large part here, as does the transient nature of this signal, hence the need for non-linear modelling.

The effect of convection is only very significant around the bass resonance where coil velocity is high (Fig. 22) and the only nonlinear elements in the thermal model are related to convection (Fig. 16). The need for nonlinear models has nothing to do with transients, but rather the dependency on coil velocity and (to a lesser extent) position. Much above the bass resonance, the velocity is low and the nonlinear elements have little influence.

You will be lucky if the temp rise is 5 degrees. Go ahead and do the experiment and report back the temp rise.

No need; the experimental data presented in the paper disproves your claim.

Listen through blue sunglasses.

Yeah, kind of. With a little waveguide that blends into the midrange cone.

 

[Grotti]

The tweeter diaphragm measures about 25 mm (data sheet) and not 30 like the one used in the Dayton EC30.

 

[Bwaslo]

Yeah, and that honkin magnet wouldn't fit in the coax with a midrange around it (unless the midrange were edge driven)

 

[Liftro]

Listen through blue sunglasses.

I also have to admit that in this shot, with this lighting, the orange isn't as noticeable, and I could get used to it.

Black tape can do it easily.

Wish the damn orange ring were maybe cobalt blue, or just black though.

Maybe the orange is Palmer's way of mitigating supply/demand complications like Ascilab is having

That is so very much better.

Yes whilst the orange ring isn't to my taste I could definitely get used to it. I tend to prefer understated monitors like my KH120's.

I’m constantly surprised by design choices in hifi. In this instance, and others, why do designers seem to have to put a stamp on things?

Especially one that is so incongruously out of place (ugly). And then they seem to double down on the thing… ‍

 

[dickiefunk]

FYI all the pictures linked in your early posts bar one were "not available" in my location (UK).

Yep me too. I'm in the UK as well.

Each to their own naturally, but the photo’s too small to be a realistic example of distance in a real room.

I think it looks less absurd on the white, but only by a tiny fraction.

The more I see it the more the orange puts me off giving away my cash.
