Omen Def Mk.II Tweeter Kit

$999.00

Kits are made to order and ship within four weeks. Upgrade your non-Radian Omen Def Mk.II loudspeaker tweeters to the same Radian 850 based tweeters we use in Soul Supreme, Druid Mk.V and Definition Mk.IV loudspeakers.

This kit will not fit the original Omen Def [Mk.I] or the Omen Def Mk.I-B loudspeakers.

Omen Def plinth assembly is highly recommended due to the added weight of the Radian 850 based tweeter assembly. Capacitor and high-pass network are installed, no soldering required.

Kit includes:

  • 2x critically matched pair of Radian-850 drivers

  • 2x critically matched high-pass filter networks for the new tweeters [featuring ClarityCap MR capacitors (ClarityCap MR is our go-to recommended cap for the 850 tweeter)

Price is for a pair, kit of left channel and a kit for the right channel.

What Are The Sound Improvements?

Treble is much smoother, detailed and intigrated—not a small or subtle improvement. Note, this kit is only offered while inventory of the 850-16 tweeter remains. Each pair of Radian 850 are matched and trimmed within the high-pass network to best blend with the full-range drivers.
