[. . . ] Twist the ends ­ this is much better than tinning them with solder ­ insert them in the terminals and tighten the terminal screws firmly. 1) For good sound it is imperative that the cables must be connected in such a way that the speakers are "in phase". [. . . ] Biamping takes this idea one step further and uses separate power amplifiers as well as separate cables for high and low frequencies. bi-amping in particular produces an additional improvement in sound reproduction quality. The special connection terminals of the Victa loudspeakers support both conventional connection and operation in bi-wiring and bi-amping modes. The top pair are for the tweeter (high frequencies), the lower pair for the woofer (low frequencies). The factory-installed metal strips connecting the positive and negative terminals are for conventional 2-wire connection and must be removed for bi-wiring and bi-amping operation. The pictures below show the correct setup for conventional operation (Fig. HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls in the central position ­ i. Turning up the bass and treble controls too far delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the speaker units!If the output of your amplifier is significantly higher than the rated power handling capacity of your speakers extremely high volumes can physically destroy your speakers. This doesn't actually happen often but you should be aware that it is possible. Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium volumes because weak amplifiers may overload much faster than powerful ones and this causes measurable and audible distortion, which is extremely dangerous to your loudspeakers. Always turn the volume down immediately as soon as you hear distortion! [. . . ] The guarantee period is not altered by the fact that we have carried out guarantee work.
