New Electrostatic Speaker
« on: 22 May 2019, 01:47 am »
Here is a new electrostatic speaker from Mellow Acoustics.
Looks very distinctive.
Seems to be a number of different finish options.
Assume a review will appear in due course.
Looks like it is pretty room friendly.
Here is the link: http://mellowacoustics.com/home.html
Enjoy.

I like the looks, but made in UK. :cry:

Very interesting round driver up top. Would love to hear that.
5.25” woofer? That says a lot about the capability. Might be great in an apartment in Europe, but over here?
For me the kick of 12”- 18” woofers is required to keep me listening for any amount of time.
However, like all products, there are those for whom the Mellow will hit all their buttons.
Nice to see some new ideas from the Brits.  :D

Very interesting!  Like the passive topology allowing your choice of amplifiers.

Response is relatively flat, but mid-band efficiency is quite low (84dB), meaning they will need some decent power (high current, actually).  They are limited to 98dB SPL max.  Impedance also goes low (<3Ω) at HF, meaning many amps would not do well with them.  I'm guessing a 60V Cherry STM would drive them nicely, maybe even the 48V version.  Has anyone here heard these speakers?

Reminds me of those vintage stand alone fireplaces.

In that case, it's Sub time (as they mention on their site). The built-in woofer would (as you say) be perfect for apt dwellers.
At any rate, it's nice to see a speaker that doesn't feel like yet another implementation of a design concept I've seen 1000x before.

… 5.25” woofer?

We get decent bass out of a pair of 5.25” in Tysen V2, but loudness levels are limited and if you need the real low stuff you will need subs.

My view on the looks: Ugly.

The AES paper on constant directivity electrostatic speakers is interesting. It shws that Mellows didn't simply decide to throw together a round electrostat just because he was tired of rectangles. I didn't like working with spherical Bessel functions 30 years but now programs such as Matlab, Mathematica, and MathCad make working with them less painful.
From the specs they seem that they would work best in smallish rooms with a sub. The figure eight radiation pattern should mean room placement similar to many open baffle designs.
I think that they look kind of space agey. A set of antennas on top of each would help.

Not thrilled with the looks but I guess I'd like them if I was George Jetson...

I can't imagine their smallish driving area would give much slam but I love the aesthetics.

My opinion: I would think the bass could sound nice with that small a driver in that large a cabinet will very non-parallel walls, but not be capable of levels that would satisfy many—also would seem to promise a small return for the amount of floor space consumed.

I'm also skeptical about the choice of a round shape for the electrostatic membrane since I think that would give rise to the strongest and most pitch-specific resonances. Maybe the triangular shape should have been employed for the electrostatic element for this reason, although it would be difficult to design that not to look weird, but it would minimize resonant modes in the diaphragm.

The triangular shape is being used to good effect in some microphones these days, e.g.,  https://ehrlund.se/

Yup, pleasing to the eye for sure, but that 5,25' bass driver a bit small, ain't it?

2 of them can be quite satisfying… Russell want to borrow them?

Thanks for the offer, but I am in the process of extracting myself from passive speakers at the moment, and to that end am selling a pair of Yamaha NS1000s along with their companion amp, a Yam B-2, in favour of these (very active):

which should be here soon.

The Hedd’s are supposed to be very good.

Gives the price as 7,500 UK pounds.
Enjoy.

Just a couple of comments.
I actually like the look of these.
Must admit that I am sick and tired of the endless box speakers, and, even with electrostats it is great to see someone thinking outside the box!!
I am completely non surprised about the base lightness of these speakers but it is good to see that the designer realised this and did not try to extract some extra base and make things worse (everything below 40hz is filtered out).
The review indicates that that the manufacturer is working on some subs for these speakers and I am sure that is the way to go.
So pleased that new electrostats just keep popping up.
And, finally I am not at all surprised that they sounded good - would not have expected anything else.
