Alpair 7A (Gen. 3) Extended Full-Range Emitter

Description:

The Alpair 7A Gen. 3A represents a large step forward in the design and production of “extended” fullrange audio drivers. In its size class, this driver delivers the widest frequency range*. The usable range now extents to 32-kHz above 80dB.This Alpair 7A has an advanced damping systems such that it delivers a usable response across its range. The cover’s magnetic attraction keeps it attached to the main driver body. Simply pull away from the driver’s main body, no tools are needed. This feature helps those box makers who design shallow cabinets or wish to optimise internal box volumes. The performance change with the cover removed is small, so the installation choices for the end user is optimal. The frame’s front cover is also made removable. While we recommend its use, the frame’s diameter is minimised to 130-mm, helping box those who want to make slimmer box designs. The acoustic performance of this driver is solidly placed in the “purist-audiophile” category. Its cone and power-train are the most micro-resonance sensitive made by Markaudio to date. With the rear and front covers attached, the driver has a SPL of near 86dB while retaining an X-max of +4-mm available for peak non-rhythmic bass loads. In a optimised box design, the system can be made capable of operating from 40-Hz to 32-kHz, possibly a unique performance for a simple cone driver in its size and class. The off axis responses and central stereo image emitted from this Alpair 7 are possibly best in class. Its cone profile and under-hung front suspension allow for a clean wide acoustic image making it easier to optimse box positioning in most listening environments.

HighLights:

• New dust cap design and Enhanced gluing method
• All New Japanese coil Design
• New Design enhances low-frequency effects
• Advanced damping system
• “Arrestor” fitted inside the magnet assembly to help prevent accidental over-loads.

Alpair 7A has an advanced damping systems such that it delivers a usable response across its range. The new “A” model has an “Arrestor” fitted inside the magnet assembly to help prevent
accidental over-loads. This new component limits extreme excursion, emitting a audible warning in the form of a tapping sound.
