Hybrid Audio Unity U2x 2-Way Mid/High Crossover (Pair)

Description

Hybrid Audio Unity U2x 2-Way Mid/High Crossover (Pair). Originally purchased as part of a component set, I ended up installing an active setup and have no need for these crossovers. New, open box, never installed.
Description
2-way Mid/High Passive Crossover (Pair) containing high-quality, low tolerance polypropylene and electrolytic capacitors and air-core inductors, PTC tweeter power protection, and three steps of tweeter attenuation, encased in the Clarus competition crossovers housing with gold-plated screw terminals.
Crossover Attributes
Unity U2x
Alignment
Second order L/R (12 dB/octave) filters for
low pass (U5, U6, or U69) and high pass (U1).
The U51-2 2-way passive crossover network
includes a unity low pass and high pass
crossover frequency of 5,700 Hz at 12 dB/
octave. The U61-2 and U69-2 2-way passive
crossover network includes a unity low pass
and high pass crossover frequency of 5,200
Hz at 12 dB/octave. The use of 12 dB/octave
filters on both low pass and high pass, often
not found in speakers in this price range,
minimizes phase-related distortion typical
of crossovers with mismatched orders, and
ensures phase-coherent imaging and staging.
The alignment topology is a shared technology
to the high-end Clarus C2x crossover design
and features asymmetrically-aligned network
components.
Network Components
Audiophile grade. The passive crossover
networks incorporate a super high quality and
low tolerance metalized polypropylene film
capacitor for highpass, and a low-tolerance
quality metalized electrolytic capacitor for
low pass, in concert with air-core inductors,
and low tolerance non-inductive resistors. No
output level switches were used in the passive
crossover design because switches add a
resistive effect and are typically of extremely
low quality. Additionally, “jumper pins” add
an unnecessary pair of splices in the signal
path to the tweeter, and were not included
in our design either. Rather, all tweeter level
adjustments are done on the board level with
dedicated non-inductive resistors; tweeter
attenuation is accomplished by selecting the
appropriate output (-3 dB, 0 dB, or +3 dB)
on the passive crossover circuit board. The
components selected are complimentary and
ensure no notable signal degradation between
the input and output side of the crossovers. The
network componentry, design, circuitry, and
polyethylene case with transparent cover are
shared technologies to the Clarus series, and
the Clarus C2x crossover design.
