The Avid Model 105 loudspeaker is the new reference standard for the critically acclaimed Avid "Series 100" line of loudspeakers. The result of extensive research, the Avid Model 105 is unquestionably the finest speaker we have maade.
Design Accomplishments
Uniform distribution of sound at all frequencies
Superior transient response characteristics
Exceptionally low distortion bass, even at high power levels
Broad, linear frequency response
"No compromise" reference monitor performance
Basic Design
All loudspeaker design involve trade offs between low frequency response efficiency and cabinet size Avid's engineers selected a floor standing, air suspension design to achieve the exceptionally low bass response, accurate reproduction and power handling capability expected in a "no compromise" reference standard monitor. The Model 105's large cabinet volume (2,3 cu. ft.) permits a flat response to 30 Hz while maintaining sufficient efficiency for use with 25 watt RMS to 200 watt RMS amplifiers.
The model 105 is a 3-way design employing five perfectly matched drivers carefully integrated by a sophisticated coil-capacitor dividing network. Several exceptional "state-of-the-art" design features are used in the Model 105 which deserve highlighting.
Long-Throw Woofer
The Model 105 employs a specially engineered 12' woofer with exceptional linearity and a long-throw (11/16"excursion) voice coil to achieve low distortion bass
"Basketless" Mid-Range
The Model 105's optimallysized 3" mid-range driver utilizes a new basketless construction which eliminates interior wave reflections that occur from the basket frame. such reflections cause irregularities in frequency response and degrade transient characteristics in conventional designs. Midrange frequencies in conventional design. Midrange frequencies are incredibly smooth and accurately reproduced with this advanced design.
High Frequency Driver Array
In addition to the superb 1" dome tweeter radiating forward, two auxiliary tweeters are employed to provide full 180 degree dispersion of high frequencies. The auxiliary tweeters are fired directly to the side rather than "angled off" to minimize interference effects with the front facing tweeter - a common problem that causes a peaky high end response on many multiple tweeter systems.
Zero Distortion Dividing Network
Drivers are perfectly integrated by an Avid-engineered dividing network utilizing only linear, zero distortion components such as air core coils.
The performance date below attest to the superb accuracy, smooth response and low distortion achieved by this system, but still fail to adequately portray the Model 105's incredibile openness and transparency which must be heard to be appreciated.
Frequency Response: is exceptionally flat, both on and off-axis, over the entire listening range from 30 Hz to beyond 18 kHz.
Low Frequency Distortion: we know of no other loudspeaker system with the Model 105's low distortion bass performance. There is less than 4% distortion at 40 Hz with an incredible 50 watts input.
Tone Bursts: are one of the best indicators of transient response: the ability of a speaker to accurately follow rapidly changing musical waveforms Note how well the Model 105 followes the 8-cycle input signal with minmum "hangover" and "blurring". These are exceptional toneburst responses, especially in the critical mid-range area.
