Rigid Speed

A CARBON FIBRE CORE

No. 25 has a heart of pure carbon, as we opted for a cone material that is stronger than steel, yet incredibly light. Carefully woven from pure carbon fibre, No. 25’s 15” cone structure weighs 70% less than a 10” cone of just two years ago. This combination of incredibly light weight coupled to remarkable structural integrity is what gives No. 25 its combination of speed and power.

Yet another benefit of the weight reduction strategy we employ is that it permits near-perfect dynamic balancing of the driver, yielding ideal behavior throughout its incredible 4” of fore-and-aft stroke.

Total Control

FINE TUNING IN THE PALM OF YOUR HAND

Begin your relationship with REL Reference by simply picking up the remote; feel its heft, how its rounded contours fit gently in the cup of your hand. This is a carefully wrought system improvement that encourages the sort of finely detailed decisions during set-up necessary to achieve the perfect balance to the ultimate system owner.

REL Reference models employ remote control in order to assist and increase ease of initial set-up. We do this knowing that once properly set, the owner will likely use it rarely during the remainder of their ownership experience as RELs truly can be set-up correctly to reproduce all forms of music and film without resorting to cheap parlor tricks like turning bass up for movies and down for music.
