High thermal dissipation and magnetic permeability plates, providing constant, even flux.
Large double magnet, for perfect control under high power, high excursion conditions.
Copper voice coil, wound on aluminium former, for startling thermal and mechanical capacity.
Back plate vent holes, for very good thermal dissipation.
Back Vented Spider support, for perfect symmetry under high excursion and thermal dissipation.
Butyl rubber gasket provides ideal coupling to the mounting surface, damping basket resonance.
Butyl rubber magnet ring provides protection against abrasions.
Internally reinforced basket, protected from abrasions by high resistance paint.
High current, tin-plated terminals.
Silver plated silicone shielded lead wires for maximum reliability and conductivity.
Basket and motor coupled and damped through special epoxy glue.
Wide-wave, resin-bonded fibre spider for mechanical reliability and consistent parameters.
High density Foam surround, for linear movement even under high excursion conditions.
Water-repellent pressed paper cone.

The speaker overall volume must be taken into account when designing a box: if the driver is
mounted with its magnet facing the box inner part, add the volume indicated in the Technical
Specifications (Total driver displacement) to total volume calculation.
The volumes of Reflex projects include tubes and ports overall dimensions.
Sealed Box
Sealed Box - Dimension
Vcc =

The box is deliberately small in
order to optimize the overall bulk
at most; this is the right solution
for those who have a narrow
space but nevertheless do not
renounce a powerful bass.

excellent dynamics.

Almost the same dimensions as
the Sealed Box Performance, yet
offering a wider extension, with a
strong sound and an excellent
articulation.

biggest sub for a powerful bass with
every kind of music.
