Product Details

Alpair-5 2nd gen 3” Full Range Aluminium Woofer Matched Pair

 

This design retains designer Mark Fenlon’s classical mechanical engineering approach to reduce mass and extend long throw operating capacity. Mark, along with Evan Yu and the engineering team spent several months of research removing mechanical restriction from the ultra thin coil body. Traditional driver designs use a “spider”, a suspension device located behind the driver’s cone. Bonded to the coil, it physically restricts a coil's ability to transfer mechanical-acoustic signals to the cone. Some other drivers use damping fluid, springs or other devices, all of which produce losses. This new Alpair 5 design completely removes all these restrictions. Its coil locates cleanly between the driver’s cone and motor sub-assembly, making the new 5 a pure free-to-air mechanical design.

 

The accuracy requirement for this new Alpair 5 component design, engineering, and detailed assembly goes well beyond typical commercial audio-driver manufacturing. The front suspension operating tolerance is measured in milli-newtons. Production Alpair 5 drivers are made to within +/- 2.5Hz @ F Zero. All production units are then pair matched to with +/- 1Hz @ F Zero.

 

The result is a detailed balanced sound representation across an ultra wide frequency band for this class of small driver. A typical box bass-reflex box application with an internal volume of 3 liters can be port tuned to below 80Hz while the driver retains is high range output up to 25kHz. The outcome is a very easy to use versatile driver suitable for many smaller applications where higher-end sound quality is desired from a mini-sized audio driver.

Some time ago I bought a set of Markaudio Alpair-5 gen2.
They sound pretty good, but they have a problem with certain frequencies, such as high violin, and piano tones when they hit these particular tones, one can hear the membranes resonate with an almost metallic humm.
They sound good, but they only get 3 stars.
For the price and M Audio's reputation taken into account, one would expect better handling of the highs.

All in all, an ok unit, I've cut mine off at 150 hz. and using a "Tang Band W5-1138SMF 5-1 / 4" to handle the bass and it seems to work fine.

(had this been a review of Tang Bang units, 5 stars)
