Aperion Audio PST MKII Planar-Ribbon Super Tweeter Pair — Extends to 40kHz for Home Theater & HiFi (Gloss Black)

Aperion Audio PST MKII planar-ribbon super tweeter pair delivers ultra-extended high frequencies — reaching up to 40kHz by extending more than 20,000+ Hertz beyond the typical 20kHz ceiling. A 5-position crossover plus an OFF setting (8, 10, 12, 14, 16 kHz) lets you set the lower limit where the super tweeter begins contributing; the OFF position disables the unit.

The crossover uses a 12 dB/octave slope. Use the front-panel treble adjust knob to tame the top end as needed, with attenuation available up to -5dB. Installation is straightforward: the super tweeter taps into the same binding posts as the speaker it’s paired with and draws power from that speaker’s feed, so no separate amplifier connection is required.

The cabinet is elegantly curved and finished to complement decor (matte black/white or piano-black lacquer), with this listing in Gloss Black. 5-way gold-plated binding posts accept bare wire, banana plugs, spades, round pins or flat pins for flexible hookup options.
