8" 2 Way Speaker. Walnut vinyl cab with black knit grills in good condition. Uniquely designed product with remarkable ability to reproduce string instruments, violins, cellos, etc. Overall vintage/warm WIDE midrange sound field. Original pleated hell type tweeters w/ matched pair EPI 4ohm woofers. Units have been upgraded, tuned, and phase improved for better, deeper bass, smoother integration of drivers, improved fidelity, and power handling.
The upgrade is not just recapping, but a better crossover design and correct cabinet dampening. These tweeters can be delicate; installing a "sharper" crossover to eliminate potential low frequency impulses which improves the reliability. The ESS speakers we have here were in storage for 20 years (possibly rep samples). Actually, we were considering becoming a dealer. Truth is, modern tweeters can have excellent midrange frequency power handling now. The ESS tweeter at one time had special capability to do low midrange well but with a slightly limited high frequency dispersion above 12 kHz. Certainly it is a better tweeter concept (pleated push/pull "accordion" ribbon) than an EMIT tweeter (high distortion, terrible dispersion, limited power out capability). Our updated speaker is voiced (corrected crossover) for more natural tonal balance, so that the lows, midranges, and highs all play out at equal levels.
