Welcome to Wolf’s! This item is brand new in the box! Acoustic Research Spirit Series 122 Home Audio 3 Way Speaker Set. The acoustic suspension woofer provided an elegant solution to the age-old problem of bass distortion in loudspeakers caused by non-linear, mechanical suspensions in conventional loudspeakers. The state-of-the-art at the time of AR’s invention was the bass reflex speaker, which boosted bass response for a given amount of cone travel by directing sound energy from the rear of the speaker cone through a port in the cabinet “tuned” for reinforcement of the direct signal from the front of the cone by the signal from the rear of the cone. Among the drawbacks of that system are the stringent design parameters for successfully achieving accurate bass reinforcement, requiring great precision and, with the technology of the day, large cabinets. Some loss of accuracy (“smearing” or “vooming” of low frequencies) was inevitable and the results of specific designs were not entirely predictable. Long hours with slide rules and prototypes drove up the development costs of new designs, keeping them out of popular price ranges. High fidelity woofers were also vulnerable to damage from extreme low frequency signals. Those issues were finessed with the invention of the acoustic suspension woofer. The 122 was a 6 1/2 2-way bookshelf with an 8 ohm impedance and 90dB sensitivity. There should be no reason why you couldn’t use it in an HT system, especially considering it will be high-passed.
