Legacy & Ayon
Broadly similar in concept to the Focus 20/20 speaker that Paul Bolin favorably reviewed in January 2004, the 25th Anniversary Focus SE is considerably more refined. It uses an AMT supertweeter and a leaf tweeter, between two unique 7" midrange units that use a cone comprising a sandwich of Rohacell and a weave of silver wire and graphite. The two 12" woofers take over below 200Hz and have a low-Q ported alignment to take advantage of the usual room gain without booming. Frequency range is specified as 16Hz30kHz and sensitivity a very high 95.4dB (4 ohm impedance).
The cabinet is narrower and deeper than the older speaker's, with sculpted edges that progressively reduce the baffle width for the HF drivers to optimize diffraction. The crossover uses Solen metalized polypropylene capacitors and braided silver Kimber Kable is used to connect the supertweeter. The drive-units are matched to within ±0.25dB and designer Bill Dudleston hand-tunes the crossover network of each SE speaker.
