The Abbey 12a is an upgraded model with a new crossover, and the cabinet is
now solid polyurethane for a structural integrity and reliability that is
unheard-of in the speaker business. This ultra stiff, low resonant
material is the ideal material for loudspeaker cabinets. The woofer now
mounts from the rear and there are no more visible screws. A grill is
now an option as well. All this added a lot of cost.
(The photos are no longer up to date - coming soon.)
The Abbey has a 12" High Performance woofer and a 12" waveguide and the same 1" compression driver as the Summa. Not nearly as big or
as expensive as the Summa, the Abbey is nonetheless a very competent performer. Below are shown two data plots in 1/10 octave resolution. These are for the horizontal polar responses. On the left is a polar map which shows sound levels as a contour map in 3 dB increments. The vertical axis represents
the angle in degrees and the horizontal axis represents frequency in hertz. These plots may seem new since almost no one in this industry would dare to show this level of detailed data. There is a reason for that!
The Abbey's admirable performance is shown below. The smaller waveguide does not control as well as the larger 15" unit, resulting in a small hole in the response directly on axis. The recommended listening position is off-axis, which means the on-axis hole is simply not a problem.
