Da Vinci technical insights
This is the EMMESpeakers The DA VINCI expounded Technical Overview; How the System works.
The undertaking DA VINCI has addressed another challenger for our Company, with the desire
to make an inventive acoustic plan encased in a progressive shape, directed by our
regular and shameless assurance to investigate new specialized courses coordinated with "breaking"
The project requirements were:
1) Full reach reduced shelf amplifier
2) High power dealing with
3) Sealed box
4) BSSE System (Box Shape for sound upgrade) by EMMESpeakers
5) High end sound multiplication
Those base necessities brought us soon to plan another idea of three-ways design, in which the Woofer has been situated on the back puzzle.
That arrangement, that in the principal look may seems extravagant and without a sense, offers somewhere around two benefits:
- Shift the customary vertical improvement to one top to bottom (req #1).
- Keep the acoustic place in a limited vertical region, all around the recurrence !range (req #5).
As it's apparent in the image beneath, the acoustic place moves just of 120 millimeters, between
the Midwoofer and Tweeter, very much like a Two-ways framework however the DA VINCI is a Three-ways.
That implies at the listening distance of 2.5 meters, the acoustic place moves under 3°
degrees, exceptionally near a point source, with obvious benefits as far as soundstage largeness, steadiness and centralization. An extraordinary outcome for a Three-ways amplifier.
Drivers choice:
The confining venture necessities, and the surprising woofer situating, put us in a long stage
of looking and testing of appropriate drivers.
The picking has fallen on 1,2" Tweeter and 5" Midwoofer by Accuton, the most current CELL fired
series, because of their extraordinary sound execution (wide data transfer capacity, very low
contortions, low stacking volume needed by the Midwoofer) (req #5), and the 10" Aluminum
Woofer by SB Acoutics, thanks its shallow profundity and, even for this situation, low stacking volume
necessity. also high power taking care of .
Bureau building and molding:
Dedicated to our customary technique in bureau development, by machine made MDF layers, che
decision has fallen soon in a shape as nearer as a cylinder, the more inflexible strong accessible.
It ensures durability, no inward resonances and of the actual bureau.
The front confound, in dark anodized aluminum with 25mm of thickness, gets from Beta and
Gamma EMMESpeakers' amplifiers the BSSE System, wherein its shape and aspects
are intended to "synchronize" the edge diffractions with the direct
outflow.
To meet the req#1, the amplifier sizes has been restricted however much as could be expected, so the limiting
posts have tracked down place on the lower part of the bureau
A topsy-turvy construction of anodized aluminum and hardened steel AISI 304 backings the
speaker. On account of the adjusted thicknesses and shapes, it has a customized consistence
with self-evening out capacity and vibrations damping.
Acoustic format and hybrid plan:
The DA VINCI, as said, has a three-ways design. As normal for EMMESpeakers, it gets over at exceptionally low frequencies with high orders of slant.
That to get exceptionally steady brilliant flaps and the most elevated detail in strong multiplication.
Investigating the organization drawing it shows up very complicated. All things considered the BSSE framework
intercedes in the drivers' radiations, setting them up to the hybrids and making the organization
less difficult than it ought to be without the BSSE framework itself.
The development of the hybrid sheets are made by Mundorf utilizing solely Mundorf
parts, as per severe quality controls.
The EMMEStand:
An amplifier with a such creative plan like the DA VINCI, has required the investigation of a
devoted stand ready to join attractive and work.
Indeed the EMMESpeakers technique for assembling, by MDF layers, has addressed
the best arrangement, leaving us the more extensive opportunity in forming and plan.
The end-product is a strong and adaptable devoted remain, with a straightforward however delightful plan.
Four circles of tempered steel AISI 204 proposition the help focuses for the DA VINCI spikes,
ensuring solidness and vibrations damping. With a base completion in dark matte and finished
paint, yet ever accessible in all EMMESpeakers gets done, it offers a simple introducing in any homegrown setting.
