TWEETER
The tweeter employed in the R 907 is using an enhanced version of the Jamo-
patented DTT-principle, which has won numerous awards around the globe.
The DTT-principle prevents unwanted cabinet-resonances in reaching the sensitive
tweeter-assembly, allowing it to maintain its clarity of sound and purity of detail.
The tweeter features a 1in textile dome
which is coated several times to obtain a
unique combination of dynamic linearity
and resonance damping, the result being
an incredibly smooth, linear, dynamic and
incredibly transparent sound.
Thanks to the unique Jamo-wave-guide the dome is experiencing a “balanced
drive” due to the acoustically symmetric loading. This dramticaly reduces
distortion, increases power-handling and enhances the requency response at
lower frequencies.
To eliminate turbulence the double-damped, optimized chamber behind the
magnet system is also equipped with an anti-resonator-plug.
And the specially designed chamber under the cloth surround minimizes air noise
and compression.
X-OVER
As should be apparent from the drive unit descriptions above, we wanted to start
out with drivers of immense fundamental quality, precisely so that we would only
need minimal assistance from the cross-over!
Consequently, the cross-over in the Jamo R 907 is of a relatively simple – in the most
positive sense of the word – low-order confi guration.
The advantages of using the 2nd order fi lters that are in the R 907 is that both
electrical and phase angles are kept at very small values, something that’s of great
importance both in terms of sound quality and the eventual load on the amplifi er.
The use of high-quality Clarity-Cap-foil-capacitors and air-coils-inductors in the
crossover further ensures sound quality.
