HI-DEF SL612 (B-stock) by DD Audio

The subwoofers of the SL600 series, which includes the DD Audio HI-DEF SL612 12-inch shallow mount subwoofer, are characterized by a very low mounting depth and the suspensions have been tuned to perform excellently in sealed and small bass reflex enclosures. To ensure high power handling, good cooling, and large excursion, the SL600 subwoofers are equipped with 2.5-inch high-temperature voice coils, 72-ounce magnets, backplate coil ventilation, and an EROM surround. One of the unique features of the SL600 is the three-layer flat cone. By compressing a foam layer between two pulp layers, the cone is as light and stiff as a standard cone, yet flat enough to allow an excursion comparable to that of a full-size subwoofer.

Frequently Asked Questions about HI-DEF SL612 (B-stock)

Welche Leistungsdaten bietet der HI-DEF SL612 Subwoofer?

The DD Audio HI-DEF SL612 is a 12-inch flat subwoofer with an RMS power range of 300 to 600 watts and a peak power of up to 1200 watts. The impedance of the subwoofer is selectable between D2 and D4 to provide versatile connection options. The subwoofers in the series are optimized for low frequencies, with the Thiele-Small parameter Fs set at 27 Hz, allowing the subwoofer to reproduce deep bass tones accurately. Furthermore, the HI-DEF SL612 exhibits a high excursion (Xmax) of 14.5 mm and a remarkable Xmech of 40 mm, underscoring its ability to remain flexible under extreme bass demands.

Wie ist die Membran des HI-DEF SL612 Subwoofers aufgebaut?

The DD Audio HI-DEF SL612 subwoofer features an innovative three-layer flat diaphragm body. The cone consists of a foam layer compressed between two pulp layers, giving it exceptional stiffness and lightness. This design allows for a comparable excursion to traditional subwoofers, but with a reduced overall depth. The diaphragm can handle large displacements, resulting in powerful and deep bass frequencies without straining the construction. This is particularly optimal for smaller enclosures with sealed or bass reflex systems.

Was ist die Einbautiefe des HI-DEF SL612 und für welche Gehäusegrößen ist er geeignet?

With a mounting depth of only 10.5 cm, the HI-DEF SL612 is ideal for installations in limited installation volumes. It is designed for sealed enclosure volumes of 22.5 to 42 liters and bass reflex enclosures of 28 to 50 liters. The small space requirement and flexible enclosure integration allow for installation in a variety of vehicle types. The compact dimensions and compatibility with sealed and bass reflex concepts make it an excellent choice for applications where space is a crucial factor, without having to compromise on sound quality.

Welche speziellen Eigenschaften hat der Magnet und die Kühlung des HI-DEF SL612?

The HI-DEF SL612 is equipped with a powerful 72-ounce magnet that provides a strong magnetic flux density to drive the diaphragm. To optimize cooling and increase performance continuity, it is also equipped with a special ventilation system. The rear wall coil ventilation and the EROM surround significantly improve heat distribution. Particularly during intense use or high volume, the ventilation of the coil gap reduces the risk of overheating, contributing to longevity. These features not only support durability but also ensure consistent performance under demanding conditions.

Welche Impedanzoptionen gibt es für den HI-DEF SL612?

The DD Audio HI-DEF SL612 offers flexible connection options by choosing between two impedance options: D2 (2 Ohm) and D4 (4 Ohm). This dual wiring allows the subwoofer to be adapted to the specific requirements of the audio system and to achieve the best possible performance regardless of the amplifier's channel count. Whether a series or parallel connection is preferred, the versatile impedance options make the SL612 compatible with a variety of amplifier types, promoting optimized sound tuning and system integration.

Welche Empfehlungen gibt es zur Installationsposition des Subwoofers?

For the best bass sound, you should position the HI-DEF SL612 so that the flat diaphragm can vibrate freely. Classic and bass reflex enclosures benefit when the subwoofer operates rearward or against a stable surface that serves as a sound reflector. Pay attention to the frame dimensions of 31.9 cm in outer diameter and 32.5 cm with gasket to ensure a precise installation. The suitable mounting diameter is 28.7 cm. These measurements support an exact installation that optimizes sound performance and increases the product's lifespan.

Wie beeinflusst die EROM-Sicke die Leistung des HI-DEF SL612?

The EROM surround (Enlarged Roll Over M-Roll) of the subwoofer offers a larger roll surface, improving deformation capability and allowing for extreme membrane excursions. This property leads to enhanced bass reproduction through increased flexibility. An optimal constellation can also positively influence the resonance behavior in the lower frequency range through the EROM surround, resulting in excellent fidelity of bass tones. Especially in dynamic music genres or films with intense deep bass frequencies, the DD Audio HI-DEF SL612 with its surround demonstrates spectacular performance characteristics.

Kann der HI-DEF SL612 in kleinen Fahrzeugen verwendet werden?

Yes, thanks to its low installation depth of only 10.5 cm and flexible design, the HI-DEF SL612 is excellent for use in small vehicles. It is optimal when space for larger subwoofers is limited, without compromising on performance. The speaker's frame is designed to fit into confined vehicle spaces, while the three-layer flat cone provides an adequate sound body. The ability to work effectively in small sealed or bass reflex enclosures emphasizes that the SL612 meets the demands of modern vehicles without loss of sound power.

Welche Rolle spielen die Thiele-Small-Parameter beim HI-DEF SL612?

The Thiele-Small parameters of the HI-DEF SL612 are crucial for its acoustic performance. With an Fs of 27 Hz, they provide a solid foundation for deep bass reproduction. The Qms parameter (7.906) indicates the mechanical quality, while Qes (0.432) points to the electrical quality, contributing to an overall system value Qts of 0.409, which signals robustness and efficiency. The Vas of 68.349 liters expresses the volume of the acoustically sealed system, which is equivalent to the suspension of the driver. These parameters assist in choosing the appropriate enclosure to achieve maximum sound fidelity.

Wie gewährleistet der DD-Aluminiumgussrahmen die Stabilität des HI-DEF SL612?

The DD aluminum cast frame of the HI-DEF SL612 subwoofer provides outstanding structural integrity and heat dissipation. Aluminum offers a solid foundation that ensures stability, especially at high volumes and intense vibrations. The rigidity of the frame minimizes unwanted resonances that could distort the sound. Furthermore, the robust design contributes to durability, reduces the possibility of physical deformations, and is resistant to heat effects due to the natural thermal conductivity of the metal. These properties contribute to consistent bass output and high sound clarity.

Jestem zadowolony z produkty który kupiłem

Ich bin zufrieden mit den Produkten, die ich gekauft habe, aber ich bin mehr zufrieden mit dem Service dieser Firma, eine Offenbarung!!! Ich hatte ein wenig Angst, weil ich es mit Lieferung nach Polen bestellt habe, der Verstärker wurde mir in vier Tagen geliefert, perfekt verpackt und DHL informierte mich, wo mein Paket ist, ich werde hier einen anderen Verstärker für meinen Bruder bestellen, ich empfehle eine Offenbarungsfirma👍

Lautstärke- und Klangupgrade für die SoundboksGo

Habe diesen Hochtöner in meine Soundboks Go eingebaut. Ein bisschen zurechtbasteln des vorhandenen Hochtönergehäuses, und voila! Absolut genialer kristallklarer Sound! Kein Vergleich zu vorher. Nun kann die kleine Go in puncto Lautstärke und Klang selbst mit der SB4 mithalten (wurde natürlich direkt von mir gleich ausprobiert :D )
Bester und effizientester Hochtöner für alle, die vorhaben, ihre akkubetriebene Bluetoothbox zu pimpen :)
