Think series & parallel speaker wiring produce the same tone? Think again!
The difference is characterized by the Virtual Impedance, a ToneDoctor discovery and the basis of several of our pending patent claims. The underlying math defines a "virtual" speaker as the difference between two speakers. It's zero only in the practically unachievable case where the two speakers have perfectly identical frequency response characteristics. This "virtual" speaker completely characterizes the tonal differences between the series and parallel interconnections of the two speakers, as the underlying math shows that frequency response characteritics of the parallel interconnection of the two speakers are identical to those of the speaker network shown below, which is simply the series interconnection of 1) the usual series interconnection of the two speakers with 2) the "virtual" speaker. Thus, the tone of the parallel and series interconnections of the two speakers differs by precisely the tone of the "virtual" speaker defined by the difference in the frequency response characteristics of the two speakers!
Our Deuce product line exploit this difference, along with the inherent differences in the frequency response characteristics of the individual speakers, to allow you to readily switch between four distinct tonalities and feels in your multi-speaker combo amp or speaker cabinet. With absolutely no degradation of your signal path or tonal quality. Its like turning your speaker cabinet or combo amp into four distinct speaker cabinets of combo amps, each with distinctly different tonalities and feels but with the same overall quality and purity of tone. And it costs next to nothing compared to what four separate speaker cabinets or combo amps would cost. And it takes up a lot less space in your studio or practice area, while dramatically lightening the load you lug from gig to gig. And our Deuce products are simply and reversibly retrofittable to your existing speaker cabinets and combo amps as a result of our patent pending reversi-fit innovations.
