Large Advent Speaker Serial Numbers
If speakers of equal impedance: You divide the impedance value by the number of speakers To determine the wattage, you add the wattage of the speakers together. Ex: If you wire 4-16 ohm speakers in parallel, you would have a 4 ohm cabinet. 2-16 ohm speakers in parallel would give you an 8 ohm cabinet. If you were using 4-100 watt speakers, you have.

NEW LISTING 5/21/18 (click on above thumbnails to enlarge photos) warranty CLASSIC STEREO SPEAKERS JBL L100 'CENTURY' #.1011A / 9060A Circa mid 1971-77 MADE IN USA for sale One of the top 'Classics' and one of the most sought after speaker models ever made. The JBL L100 ‘Century’ speakers.
It's hard to expand on what's already been written out there about these speakers. Most fans of these know some version of the JBL L100 story or link to an appreciation web site. They have been one of my favorites for some years now, and I finally just finished a pair for myself to keep as well.
They are capable of high volume levels while producing 'pounding' & 'tight' bass with great balance on the top and mid end. Just a great 'all-around' speaker for home audio listening or recording ‘studio monitor’ use. Just as happy with a medium-small size amp as they are with amps of larger size (probably not efficient enough to enjoy with a small wattage, under 25 Watts or single ended tube amp). Tweeter diffusion foam replaced. All drivers were removed and reinstalled into cabinet with ‘added’ gasketing material under their frames to further reduce any possibilities of vibration or acoustic anomalies. 'High' and 'Mid' Attenuators checked for functionality (these attenuators have wipers that go 'a bit too far', thus go past their coils at 100% rotation, so for 100% signal, adjust to extreme 'clockwise', then back them off 1-2mm). The tweeters have new dispersion foam installed.
Grill front frames re-covered and look fabulous (while not shown in the above photos, the 'JBL' logo badges are intact on the frames). Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 20-3kHz. Then came our standard, 'abusive' test recordings. The only cosmetic issue worth mentioning, is that the top of one cabinet appears to have been re-veneered, and does not match the cosmetics of the other cabinet (see photos above & reflected in the price). Other than that the front corners and edges are all nice and crisp with virtually no wear. Cabinets were finished off with a coat of ‘ Lemon Oil’ and then hand-rubbed with ‘Feed-n-Wax’.
They look GREAT! Following the above work, these speakers are ready to go! We auditioned this pair well. Following the above mentioned 'barrage', our demo cuts ran the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, and a few others, all digitally recorded and some 'DDD'.
'Solid', punchy and 'tight' low-end, with no 'mush'. Overall, Great 'tone' quality, but then again, they're one of the most famous and sought after speaker models ever made. Heck, most of the above cuts may have been originally mixed on a pair of these.
From an original JBL brochure from ’73, “The JBL L100, is the most successful speaker ever produced by JBL. It may well be the most successful loud speaker in its class ever produced by anyone.” “The JBL L100 is essentially the JBL 4310 studio monitor in a more ‘handsome cabinet’ and was the most ‘expensive bookshelf speaker’ in it’s time.” JBL L100 Century FEATURES: - 3-Way, Bass Reflex cabinet design - 12' / 30cm, JBL 123-A, Die-Cast-aluminum framed, 'Ribbed', cone woofer, coated with ‘Lansaplas’, an ‘anti-resonance’ material to reduce radial ‘eddy currents’ (reason for the ‘white’ color), w/ 3”, ‘Edge-wound’ copper ribbon Voice Coil, surrounded by a powerful 6.75 lb ‘AlNiCo V’ magnet.
