Key to their sophisticated sound is an advanced topology
crossover network with polypropylene and low-DF electrolytic capacitors, custom wound inductors, and thermal and current protection.
Here we save money with DSP by throwing out the whole
crossover network.
The name, Phase Technology, is derived from the properties of its
crossover network. The speakers' crossovers are optimized so that the drivers are in-phase when crossing-over from one driver to the other.
The signal is steered to each driver by the
crossover network. How many things are wrong with this?
(Think of your typical bass-drum thwack.) The tone is sent to the
crossover network and it routes the abrupt beginning to the satellites --and sends the steady-state, lower frequencies to the subwoofer.
The two Cantata midrange drivers in each system (which, if you remember, are really not high-pass filtered by the Cantata
crossover network) are still prevented from dealing with low-bass signals.
The
crossover network is a third-order (18 dB/octave) design, with the transition point at 2.5 kHz.
Here we have a pair of three-way NHT M6 satellites, on their dedicated stands, coupled with two of the company's new W1 subwoofers, two of their subwoofer amps, and their rather elaborate outboard
crossover network into their "Evolution" speaker package.
The AR-302 is filled with damping material to the point that it was hard to get the
crossover network back in the box.
The
crossover network that is used, or not used, in these usually bi-amplified speakers is also inherently flawed.
With over 25 years of experience, co-founder and lead engineer, Dean Vang, passionately designs and engineers every in-ear monitor to deliver only the most remarkable audio reproduction possible with proprietary Empire Ears drivers and
crossover networks.
Typical applications include power amplifiers, power supplies, switching regulators, SCR and triac controls, speaker
crossover networks, RFI suppression and filters.
