De JBL L300 Summit werd gefabriceerd van 1975 tot 1982 en waren het audiofiele wonderkind van JBL in hun gloriejaren.

Een Amerikaanse review van ongeveer tien jaar geleden schrijft:

JBL has made some incredible speakers in their history, and there is no doubt that the Paragon and the Hartsfield are two of their greatest achievements, and few also would argue that the 4345 has the slight edge on the L300 Summit for audiophile sound quality. But for many reasons the JBL L300 Summit is an icon of not just the JBL product line, but the audio industry altogether. It is something akin to the 1957 Chevy in capturing the essence of an era. In the 1950’s and 1960’s, if you dreamed about a car, it likely was an early model Corvette or the 1957 Chevy Bel Air (probably the convertible!). In the 1970’s, if you dreamed about a set of speakers, it was this pair of JBL L300 Summits. The L300 Summit represents an era of historic greatness, when products that were “Made in America” meant that it was the most innovative design, the best quality materials and components, the absolute best construction and attention to detail, and the best performance possible. In 1975 JBL was at its zenith in terms of Quality Control, Engineering and Design Innovation, and these L300 Summits were State of the Art. Impeccably styled, superb cabinet construction, and absolutely phenomenal driver quality created what was then the astronomically priced statement speaker at $3,000 a pair in 1975 – 33 years ago!

Technical details

These speakers sound fabulous – no other way to describe it. The combination of finesse and delicacy coupled with the amazing muscle of the 15” JBL 136A woofer create a sound that is just indescribable. The combination of the 136A woofer, the LE85 midrange horn and the incredibly delicious 077 crystal slot tweeter were the culmination of more than 20 years of JBL research and design, and to say that they have withstood the test of time and are still relevant today is a huge understatement. The reason that the demand for these premium speakers is so high is that the drivers out-perform almost everything being made today. This speaker will blow you away with its carefully blended combination of graceful and intimate detail and raw, chest pounding power - it is the quintessential 3-way speaker system.
This is an extremely pure and clean design – a 3-way speaker with extremely high-end components include a massive 15" 136A woofer with 4 inch edge wound voice coil and an optimized alnico motor structure for ultra low distortion. The authoritative bass performance of this classic woofer still rivals the best modern designs. The LE85 midrange features a 1.75 diameter edge wound aluminum voice coil and an alnico motor structure. It fires through a cast aluminum exponential horn and wide dispersion lens assembly. The 077 tweeter features a very efficient ring radiator design with an aluminum diaphragm which has been shown to be one of the most effective ways to achieve flat, extended frequency response beyond 20 kHz. The design of the high frequency driver matches the directivity of midrange horn beautifully which leads to a near-perfect transition between them.

Er staat geen prijs bij, maar uit nieuwsgierigheid heb ik de verkoper via e-mail gevraagd hoeveel hij of zij ervoor zou willen hebben. Ik weet dat enkele Nederlanders deze speakers ook ontdekt hebben, dus voor een prikje zullen ze waarschijnlijk niet weggaan...
