It is impossible today to determine sound quality of speakers from specifications. The flaws in speakers which limit clarity or cause listening fatigue do not show up in specifications or in most cases even in elaborate acoustic measurements. 
My designs are based on decades of learning what goes wrong with speakers that correlates with unpleasant listening experience and to avoid those problems. 
From a positive point of view, it is important to reproduce the entire range of what human hearing is capable and to produce that uniformly in three dimensional space. 
For what it is worth, I do include a set of specifications.  

Dispersion 
Sound normally spreads in three dimensions, at all frequencies. Therefore, so does our speaker, unlike many others. 

Ringing 
Speakers should not sound like a bell; hence, the woofer magnet is encapsulated, damping material is inside the cabinet, the tweeter coil is  damped by a magnetic liquid, cabinet walls are thick and braced, edges of the cabinet are rounded. 

Phase Response 
As a function of frequency, the rate of change is minimized through careful control of reactive components in the crossover, woofer, tweeter and cabinet. 

Room Acoustics 
The speaker is designed to slide the sound smoothly into the room from its assigned position, without causing resonances or interferences. 

Frequency Response 
40Hz to 10,000 Hz ± 2 dB 
30 Hz to 17,000 Hz ± 4 dB 
20 Hz to 20,000 Hz ± 6 dB 
Dimensions:  
13½” wide; 9” deep;22” at front,25” at rear 
Power Maximum: 50 watts continuous 
Power Recommended: 200 watts recommended for handling transients 
Rated Impedance: 6 ohms 
Minimum Impedance: 4 ohms 
Crossover 
The woofer is designed mechanically and electrically to roll off naturally, no additional filtering is necessary from the crossover. A two pole network adds to the natural rolloff of the tweeter, additional components equalize the tweeter response to achieve maximum flatness in the prescribed room location. 
Frequency: 1600Hz,  
Woofer Slope: 24 db/octave 
Tweeter Slope: 24bd/octave 
Driver Complement 
 Woofer: 6.5” with ±” linear travel 
 Tweeter: 1” soft dome type with magnetic  cooling fluid 
Shipping Weight: 30 lb.
