REFERENCE – ABOVE ALL

 

2018 has seen products grouped into the R category. Riot, Rage & Rampage which is the top tier.
The series that has always been secluded is the Reference. Amplifiers, subwoofers & loudspeakers are all cornerstones and included in the Reference series. The REF63AA (Audiophile Acoustics) – 3 way speaker system is the latest addition to the Reference line-up.

Close to the goal

If the 3 way system needs to be complemented, the High End low frequency tranducers REF10 and REF12 offers outstanding performance in both compact, sealed and ported enclosures. With an FS as low as 20 Hz you will never wonder if you can reproduce the accurate scene with all details included. Common for both drivers are a 3″ voice coil in a dual 4 ohm configuration. An option chosen to offer better configurations for the amplifiers matching the reference in terms of output power. Another point was to increase efficiency on both subwoofers and the amplifiers. It might not matter you think, but when you are a purist, an accurate sound reproduction, or as close to it is the goal.

The parameters

Non pressed paper cones blended with cotton fiber offers a warmer, more natural sound. Not only is it a light weight material, but it offers  an exceptional stability and performance. An ordinary foam surround would be the limiting factor for the xmech, besides it would also add unnecessary mass causing the T/S parameters to become less favorable. A wide roll expandable thin rubber surround increased the efficiency, lowered the fs and offered a better transient response. The progressive pc/nomex blended spider affects the parameters the least in this configuration. Even after long time use, the suspension of the subwoofer should be within tolerance of its initial specs.

*It is essential that our speakers are given time to allow the suspension to soften up. Depending on use, this may take several weeks. While this process is undergoing, it is not recommended to apply full amplification power according to the speakers specs. Once the moving parts have been broken in, the performance of your speaker will increase.
