Cool! Should I ask here what you purchased? Might be off topic. I am curious what a acoustician purchased for his own home use.
The tilt is not a problem, but its general not optimal continuity which can be seen better at the normalised plot:Vertical directivity IS OPTIMAL bc it is optimized for a 10* downward angle. This is not a stereo speaker designed for the middle of your living room. It is an inwall speaker designed to be a little higher up on the front wall behind a perforated projection screen or on a side wall, also above ear level .
This looks very nice! A great spinorama and a impressive array of impressive appearing drivers. Okies I won't post more about this because this is a review thread. I'm already being bad.I am in the process of replacing my JBL C222HP LCR speakers with KEF Ci5160REF -THX. I asked KEF to send me the spinorama chart. It took them a while but the delay turned out to due to their updating the model to THX spec. I thought the chart will be valuable information for the forum. I have...www.audiosciencereview.com
For the intended market, home theatre with fixed seats, and with good alignment it’s acceptable but for home theatre with a TV and scattered seating it’s not good.The tilt is not a problem, but its general not optimal continuity which can be seen better at the normalised plot:
That's what I said, no?The Tonal Regression Curves are very telling, but I guess these speakers would be installed by the company, and they can easily put in parametric EQ filters to mimic near perfectly a linear tone control which I'm thinking they might tune with the customer present.
The following EQs are “anechoic” EQs to get the speaker right before room integration. If you able to implement these EQs you must add EQ at LF for room integration, that is usually not optional… see hints there: https://www.audiosciencereview.com/...helf-speaker-review.11144/page-26#post-800725
Probably need professional tuning....
Great find!So why did nobody mention that this thing has a super cool waveguide? It's actually an up-firing compression driver and the waveguide has some resemblance to what B&O uses:
It has been redesigned to work on a flat baffle. They also have speakers that look much more like the B&O version, like this one:
Definitely an interesting company. Talking about research orientated manufacturers...Developed by Grimani Systems founder Manny LaCarrubba, the Conic Section Array™ (CSA) is a novel waveguide that represents a new class of ultra-wide dispersion device. The CSA grew out of Manny’s work with a previous invention called Acoustic Lens Technology (ALT). Danish consumer electronics company Bang & Olufsen utilizes ALT. You can find Manny’s invention rising out of the dashboards of several of the major European automotive brands, and in nearly all of B&O’s higher end speaker and video products.
What these waveguides do is solve the age-old problem that all conventional high frequency drive units have with the beaming high frequency content in an ever increasingly narrow coverage angle. This means that you can only hear full frequency content if you are directly in front of the speaker (or nearly so). It’s important to realize that ALL loudspeakers exhibit this behavior to some degree –Acoustic Lenses or a Conic Section Array™ GREATLY mitigate the problem.
This is a review and detailed measurements of the Grimani Systems Rixos-L active DSP speaker. It was sent to me by the company and costs about USD $8,200. A free application is provided...
The review said, the amplifier is a 3rd party DSP amplifier from the Italian company, Powersoft (Mezzo 604A). I assume the app comes with the amplifier.Do you have to spend the eight large to get the free application?
All or any combination of the above.Seriously, though, I wonder how folks playing at this level decide to buy something like this? Do pro installers have 'showrooms' that prospective customers can demo the products, and possible competitors? Or do they just hand their contractor the keys to the front door, and say, "Put something in it that will astonish me, and call me when it's finished?"
