Avid Model 101
A two-way column with a vented box and a heavy, rubber-edged eight-inch woofer, built for deep bass. Reviewers split on it.
Overview
The Model 101 is a two-way, four-driver column loudspeaker built around a large vented enclosure. Avid's advertising was candid about the engineering problem. It called it the "bass vs. midrange dilemma": a six- or eight-inch woofer gives better midrange dispersion than a big ten, but a small driver in a conventional box struggles to reach genuinely low bass. Avid's answer was to use the vent to extend response, not to boost efficiency. The ad copy described the alignment as essentially a fourth-order Chebyshev filter. The claimed payoff was bass down 3 dB at 30 Hz from an eight-inch woofer crossed over at 2500 Hz to the high-frequency section. A period announcement in Audio (July 1976, p.14) listed the Model 101 as a two-way, four-driver column with a large vented enclosure for extended bass at medium efficiency. It quoted 30 Hz to 18 kHz ±3 dB and 180-degree high-frequency dispersion, at a price of $135.00.
That woofer was no off-the-shelf part. Avid said the design took over a year to perfect. It used an unusually large magnetic structure and a specially developed rubber-edged cone of roughly twice the weight and stiffness typically used.
The record gets messy on how the speaker was received. Avid's advertising ran the same "right choice for most listeners" copy across multiple issues, including Audio (October 1976, p.17) and Audio (February 1977, p.27). That is marketing, not a verdict. The independent listening came from HiFi-Stereo (April 1977, p.44), in its test of the Avid 101 Speaker System. The reviewers noted that against some speakers on hand the 101 sometimes seemed lacking in deep bass. Further listening led them to conclude the comparison speakers were the ones adding something not present in the program material. So a speaker sold on its low-frequency extension first read as bass-shy, until the reviewers decided the competition was exaggerating. Treat the 30 Hz claim as an alignment figure, not a guarantee of weight in the room.
Anyone shopping today should watch for a documentation trap. The Model 101 name was used by more than one company in this era. A chunk of period material describes a small KEF-designed Reference Series Model 101, a quarter-cubic-foot sealed box with an S-STOP protection circuit. That is a different product entirely and should not be confused with this Avid column. An Advent Model 101 Dolby unit also appears in contemporary writing. The Avid 101 is the vented floor-standing two-way, so match on that description before buying.
Avid backed the speaker with a five-year warranty. For a $135 loudspeaker in 1976, that was a confident statement about the woofer and cabinet holding up. As with most speakers of the period, the cabinets and crossovers are straightforward to service. The rubber woofer surround decides whether a given example is a keeper or a project.
