Questions about the newer Allison Model 1 and Model 4 Speakers?


Recently picked up a couple pair of the newer Allison Model 1 and Model 4 Speakers and do not have any literature or manual for them, would like to know the ohm load, sensitivity and power handling of each model? There is not a lot of information on these newer model Allisons. If anyone has any information or where I can search please let me know, also interested in any newer literature or manuals for these two models.

Found this with a bit of Google searching. This is for the Allison Ones.

Specifications Speaker complement:Two 10" (254 mm) woofers;Two 3½" (89 mm) Convex Diaphragm mid-range units;Two 1" (25 mm) Convex Diaphragm tweeters

Crossover frequencies: 350 and 3,750 Hz Crossover network: LC half-section at both crossover frequencies. Air-core chokes and non-polar computer-grade capacitors are used. Three-position control switch (accessible from front) supplied for selection of system acoustic power response, from nominally flat to concert-hall balance slope.

Impedance: 8 Ω nominal (7 Ω minimum at any setting of balance switch) Efficiency: better than 0,7% when placed at floor-wall intersection.

Minimum amplifier power: 30 watts per channel to produce 100 dB sound pressure level in most domestic room environments. Acoustic power output capability: 0,5 acoustic watt minimum , over full frequency range, with 70 watt peak input.

System resonance frequency: 45 Hz, nominal Effective system Q: 1.0. Low-frequency response -3 dB at 35,5 Hz, -6 dB at 29,5 Hz

Enclosure: Stabilized Radiation Loading sealed acoustic suspension design.Outside dimensions: 40" high by 19" wide by 10¾" front to back (1002 cm by 483 mm by 273 mm). Internal volume: 2,550 cubic inches (41,8 liters).Material: High density particle board veneered with walnut, oiled finish

Weight: 67 lbs (30,4 kg)Full Warranty for Five Years

Here's the Allison Four specs I found:

Specifications Speaker complement:One 8" (203 mm) woofers;Two 1" (25 mm) Convex Diaphragm tweeters

Crossover frequencies: 2 kHz Crossover network: LC quarter-section. Air-core tapped choke and polyester capacitors are used. Three-position control switch (accessible from front) supplied for selection of system acoustic power response, from nominally flat to concert-hall balance slope.

Impedance: 8 Ω nominal (6,5 Ω minimum at any setting of balance switch) Efficiency: better than 0,7% when placed with back against wall.Minimum amplifier power: 30 watts per channel to produce 100 dB sound pressure level in most domestic room environments.

Acoustic power output capability: 0,5 acoustic watt minimum , over full frequency range, with 70 watt peak input.0,25 acoustic watt minimum in lowest octave, with 35 watts input.System resonance frequency: 52 Hz, nominal Effective system Q: 1.0. Low-frequency response -3 dB at 41 Hz, -6 dB at 34,5 Hz, when placed close to center of large wall. Low-frequency output increases when system is placed in typical positions with respect to side wall and floor or ceiling.

Enclosure: Stabilized Radiation Loading sealed acoustic suspension design.Outside dimensions: 11" high by 19⅜" wide by 10" front to back (279 mm by 492 mm by 250 mm). Internal volume: 1,265 cubic inches (20,7 liters).Material: High density particle board veneered with walnut, oiled finish

Weight: 23,5 lbs (10,7 kg) Full Warranty for Five Years
I believe those specs are for the older model allison speakers. It is the newer models circa 2002-2006 i believe.
