The Pencils are a small range of easy-to-build floor-standing cabinet designs for Mark Fenlon Audio drivers. They use a combination of traditional quarter-wave design, a custom T/S volume alignment, and Transmission Line damping to provide a balanced response with a flavor of both vented and TL enclosures. The Pencils are designed not to require any form of correction circuits for step-loss. This is achieved through a combination of the compensation already built into the driver responses, and the damped air alignment, which together bring the system response ~flat in-room. The impedance load is easy, being largely un-reactive, and driver displacement is well controlled. Many have been built, and with many happy end users. See diyAudio.com for discussion, comments, variations, reviews, and help. Default recommended damping quantities (assuming Dacron hollow-fibre material) are suggested in the plans; tailor these if required to suit your own amplifier[s] / room / taste. A removable back is employed on all boxes to allow easy tweaking of the damping
This kit is priced per speaker for reduced shipping costs. Please order two if you want a pair.
