Used, in good or better condition, JohnBlue No. 3 (JB3) ported speakers, in black piano finish (see pics). These sound excellent, and come alive with a bit of power, especially with a nudge, not much, of the bass tone control, 1-2 dB. 3 inch full range / wideband speakers. Efficiency: 87dB w/m Impedance: 6 Ohm Max power: 30 watts Dimension: 208 x 129 x 188 mm (H x W x D) (Roughly 8 1/8 x 7 1/4 x 5 in.) Weight: 4.2 kg/pair Wiring: All internal wiring in gold-plated pure solid core copper. Cabinet: MDF construction with 1mm piano gloss lacquer (in Black, White or Red and proprietary damping material. Driver: 3-inch full range driver with special resin cast waveguide and, anti-fungus treated paper whizzer cone. The 3 naked driver has a frequency response of 90Hz to 21kHz. When coupled to our bass reflex cabinet, it extends to 50Hz. The high frequency actually approaches the realm of superior tweeters, reaching 21kHz at -1dB and 23kHz at –6dB. In terms of bass performance, we must bear in mind the physical limitation of a 3 driver. Even so, the JB3 can deliver bass extension beyond expectation if you follow these three simple rules: (1) A good solid foundation. (2) Good synergistic speaker cable. (3) Place the speakers with the bass reflex ports to the inside. The speakers should be positioned 150 - 180 cm apart, 180 - 220 cm from the imaginary middle point between the speakers to the listening position.

NB Cash on collection (Farnham, Surrey). Daytime only, not evenings. JohnBlue Audio JB3 Full Range Driver Speakers (Surrey) These JB3 speakers are in excellent condition, no obvious marks. Fully working, both sound perfect. I highly rate these super classy small speakers. I will only sell them if the price is right. I want to downsize my collection but I still enjoy them. I tend to use them as every day background speakers. Ideal for a bookshelf, desk or sideboard. They are a single driver design without crossover so the mids are seamless and perfect in the time domain. Usual single driver pros and cons. Excellent attack in the mids, brings out more real tones and timbres in that region. Like wow that sounds more alive than it did on the other speakers! Refined for a single driver design but not as refined as the best 2-way designs. They use the Dynavox LY302F driver or a custom version of it. Can be used either as small hifi speakers or near field monitors (like the classic Auratone but wider range bass/highs). HQ copper terminals, bare wire or 4mm plug. Matched serial numbers. In the rarer/later Alpine/Bugatti racing blue piano gloss finish, lovely quality. Made in Taiwan circa ten years ago by a small boutique audio brand. JohnBlue Audio Arts JB3. Efficiency: 87dB w/m Impedance: 6 Ohm Max power: 30 watts Dimension: 208 x 129 x 188 mm (H x W x D) Weight: 4.2 kg/pair Cabinet: MDF construction with 1mm piano gloss lacquer. Each speaker comes with a thin soft white cloth sack that protects the gloss finish. They are excellent small full rangers and had great reviews. Very clear mids and great tone. They can give quite a big sound even in larger rooms. Ideal for small class D amps. The Firestone Big Joe amp and the Amptastic Mini-1 tripath amp are not included. Best time for collection would be daytime, not evenings. I can show them working. Im near Farnham, 10 miles SW of Guildford. Cash on collection before taking away.
