Deep Harmony
Passive two-way loudspeaker 17 cm Mid-woofer with 900 acceleration factor and 28 mm Tweeter in treated silk Spera Experience modified, with circular waveguide Trapezium-shaped phenolic-bonded marine plywood cabinet with non-parallel internal walls processed with CNC machines.
Internal broadband acoustic trap and semi-exponential profile wooden tuning tube to reduce turbulence.
SKU: “Deep Harmony”
Finish
External finish in high quality natural taupe leather and 8mm white plexiglass trim panels.
The aesthetic takes up that of the superior Delirium model, however, using plexiglass instead of aluminum to contain costs without sacrificing the elegance of the design.
The tweeter is mounted on a plexiglass filigree fixed on the cross-over plane which, being external to the cabinet and suspended by rubber bands, does not receive any vibration from the cabinet.
The cross-over filter is of parallel type at 12 db per octave with different electric and acoustic frequencies.
The conductors used for internal wiring are all pure solid-core copper.
The cross-over filter is equipped with impedance compensation from 38 to 20.000 Hz that can be activated via jumpers and this feature, in addition to the nominal load of 13 ohm make it an extremely easy load for any amplifier, especially for tube amplifiers which will thus be able to return all the linearity of response and the dynamics of which they are capable.
There are four solid copper insulated connectors to be able to use bi-wiring or bi-amping.
