ESS PS-9C

# 27392

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.

Paradigm Mini Monitor v4

# 38687

Rev 6AFF Audio Pro Modified (Rosenut). This inexpensive speaker has a superior built cast frame woofers with butyl rubber surrounds which will last 20 years and super lightweight titanium dome tweeters which have a special phase-correcting lens over the tweeter, as well the use of a ferro fluid dampening coolant in the tweeters magnetic gap to improve efficiency and dynamic range capability. The cabinet is heavy MDF board with bracing around the internal walls. What is crucial is that the dynamic efficiencies of the woofer and tweeters be similar, therefore the sense of bass to treble levels remains in timbral balance at very low or high acoustic output listening levels, which this modified speaker does incredibly well.

Behringer Truth B2031a (AP modified)

# 50188

Pair of powered monitor speakers, highly recommended product. New in box. AP modified crossover design for better fidelity and phase response and to protect tweeter from DC and transient damage. Added cabinet & cone dampeners. Model 2031A are amplified speakers. I suggested 2031 passive design, and to use any good 40-100 Watt amplifier. Check out the Behringer website for a picture. A modified set is $448. We modify the 2031 to be a near field monitor where midrange tone is "warmer" or slightly receded image by a 3db through about at octave between 800 - 2000 H3. A far field monitor version is slightly brighter or stronger midrange and designed to listen at 4 to 8 feet distance. Basically flat response is perceived at that range. Near field version is for 2 to 5 feet away listening, and indeed most BSEE acousticians agree that a near field should be dipped in midrange. In both cases, the modification consists of improved multi section crossover (it presently has a very simple 4-part crossover) as well. We install a dampening blanket between the internal chambers, dampen tune one of the port slots and finally apply soft felt clone dampeners to improve midrange level and tonal match to crossover. The cabinet is now tuned to reproduce 40 Hz powerful and clean. The speakers are very heavy design with cast frame woofer, using high density MDF cabinet, very well done. No grill cloth is included by design. Shipping can be $38 or so to get them to you.
