Before details of our construct experience here’s some background info:
The high quality 18 mm birch ply kit was by Stefan Whatcott. The designer Dr. Scott Lindgren (Woden design) has matched his Pensil cabinet to the character of selected highest quality units of the Pluvia II production from manufacturer Markaudio. Together they achieve a desirable synergy of purposeful musicality.
It’s a single point ‘full range’ source with ultra lightweight composite metal cone of special construction with a particular specification of suspension which allows for very tight tolerances and long throw through a big magnet assembly allowing fine detail addition even at pumping bass extremities.
These factors mitigate the limitations and maximise the lovely advantages of single point sources. Dramatic transient speed in macro dynamics and micro dynamics, imaging and cohesiveness in the sound of instruments that is obvious with reproduction of acoustic kit and vocals. When attack and decay harmonics distinguish top hifi –eg. nails on guitar strings, when the absence of crossovers, comb effects and phase shifts allows the recorded beauty in the ear sensitive 200 Hz to 4 kHz band to manifest enchantingly in room.
The drivers frequency graph shows strong ability around and below 100 Hz and the cabinet design amplifies the back wave in this range with its quarter wave resonant air coupled vented tower (a modified ‘mass loaded transmission line’ MLMT). Being able to tune the sound balance to suit your room/ taste is a distinct advantage and easily achieved using absorbent wadding through a removable panel. It will not of course turn it into a 25 Hz bass bin. It will give the intended expressive phrasing as required for stand-up bass.
