WHT PR1 MKII FALCON
FULL RANGE SPEAKERS
The PR1 MKII combines a very unique blend of bass reflector and unconventional rear loading without the traditional cupped-hands colorations or slow, ill-defined bass typical of all ported designs. The main driver is a custom-built 8" unit of our own design mated to the Neo ribbon. At 43" x 11" x 14" HxWxD, the dimensions are deliberately living-room friendly while the combination of piano-gloss lacquer on the sides, real black leather on top and front and exotic red Jarrah wood for the scoop will appeal to even jaded interior decorators.
A true 2.83V/ 1w/1m sensitivity of 96dB combined with a nominal 10-ohm impedance that never drops below 8 and doesn't rise above 19 welcomes low-power tube amps as well as high-power solid state.
Exceptional speed and coherence are made possible by true in-phase operation of both drive units within their respective pass bands. Bi-wirable, the weight is 77 lbs. each.

1.) PR1 MKII parts are cut from a low resonance HDF using CNC Precision Technology.
2.) Internal walls are lead lined first then treated with bitumen and MIS (Multipurpose Isolation Solution).
Lead lining is not a new process and it has been known to loudspeaker makers for years. Unfortunately when mass production was introduced to the lead lining became almost impossible to apply and became very costly for the audio industry.
4.) WHT own 8" woofer is designed to work with special phase plug and hand made minimal crossover. Point to point silver annealed wiring is used to provide maximum transparency speed and accuracy when coupling with modified ribbon tweeter.

About Jarrah wood: Jarrah [Eucalyptus Marginata] stock is composed of a mix of Jarrah and Karri wood, two species so closely related as to, shy of DNA testing, be almost impossible to tell apart. Australian builders have used both woods inter-changeably for over a hundred years. Jarrah and Karri trees are majestic, standing over 245 feet in height, with trunk diameters of up to 10 feet. They are the tallest trees in Western Australia where they dominate the forests.
The habitat range of Karri and Jarrah is restricted to a relatively small area of the SouthWest, from near Albany to Cape Leeuwin, on deep loamy soils where rainfall is in excess of 30 inches annually. The trees are a true gum with smooth bark on a long shaft-like trunk. When the old bark is shed, the bark can be seen in varying colors of orange, yellow, gray and white. The leaves are broadly lanceolate, dark green above but paler underneath. The umbels of 3-6 white flowers produce a very high-grade honey which is generally recognized as the best in Western Australia.
