Description

A four-driver JBL tower in the Cherry finish, with a genuine bi-amp panel.

What it is

The E80 is the middle of JBL’s Northridge E Series floorstanders, and it is a three-way with four drivers rather than the two-way-with-a-second-woofer arrangement that most towers at this size settle for.

Two 6-inch PolyPlas woofers handle the bass. A dedicated 4-inch PolyPlas midrange handles the voice band on its own. A three-quarter-inch titanium-laminate dome sits above them in an Elliptical Oblate Spheroidal waveguide. The crossover hands off at 300 Hz and again at 4 kHz, which means the midrange driver owns the region where voices and most instruments actually live, and is doing nothing else while it does it.

That matters more than the driver count suggests. In a two-and-a-half-way tower the woofers are asked to produce the bass and the midrange at the same time, and the midrange is what suffers when the bass gets demanding. Giving the mids their own driver is the reason a three-way holds together on complex material.

The JBL engineering

The cones are PolyPlas, JBL’s own material — a cellulose-fibre base reinforced with a polymer, stiff enough for clean bass and internally damped enough to keep the midrange free of ringing.

The crossover is JBL’s Straight-Line Signal Path network, built on the principle that the less circuitry the signal passes through, the more of it survives to the drivers. The cabinet is ported with JBL’s FreeFlow flared design, which reduces the chuffing a straight-cut port produces when the bass works hard, and the front is a low-diffraction IsoPower baffle.

The connection panel

Dual sets of gold-plated five-way binding posts — four posts a side rather than two, joined by removable jumpers. That is a real bi-wire and bi-amp capable panel. Run them conventionally with the jumpers in place, and the option is there whenever you want it. The posts take bare wire, spades or bananas.

They are magnetically shielded, and they ship with both metal spikes for carpet and rubber feet for hard floors.

The finish

JBL offered the Northridge E Series in Black Ash, Beech and Cherry. Almost every E80 that surfaces is Black Ash. This is the Cherry — JBL gave it its own model number, the E80CH — and it is much the least common of the three.

At 8 3/8 inches wide and 36 1/2 tall these are a slim tower rather than a wide one, and in a warm red-brown they read as furniture rather than as home theatre equipment.

They retailed in Canada for around $1,200 the pair.

Condition

Very good. The cabinets present well and the pair is working properly.

Four drivers, a dedicated midrange, and a bi-amp panel most towers this size never had.

🔌 Speaker Cable, Bi-Wiring and Connectors

The dual posts here take bare wire, spades, pins or bananas, and they mean you can bi-wire or bi-amp if you ever want to. Our bi-wire speaker bridges replace the factory straps with something considerably better made. We hand-build speaker cable here in any length you need on our Custom Speaker Cable Builder, terminated with our own gold-plated banana plugs or spade connectors. 👉

🦶 IsoAcoustics GAIA III — the Right Rating for These Towers

At 42 lb each, the JBL Northridge E80 sits well inside the rating of IsoAcoustics GAIA III isolators — 70 lb per set of four — which decouple each cabinet from the floor. Ask us to confirm the thread fit to these cabinets before you order. On carpet, add GAIA Carpet Discs. We are an authorized IsoAcoustics dealer. 👉

JBL was founded in Los Angeles in 1946 by loudspeaker engineer James B. Lansing, first as Lansing Sound, Inc., and the JBL name came into use in the 1950s. We carry JBL bookshelf speakers, towers, centre channels, subwoofers and portable speakers. We've had more than 75 JBL listings so far, covering more than 50 different models. Every used JBL here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

Our best-selling JBL models so far: the Link 10 portable speaker, then the Northridge EC25 and N Center centre channels, the E30 bookshelf speakers and the vintage L46.

The JBL story, 1946 to today

James B. Lansing, who had been vice-president of engineering at Altec Lansing, set up Lansing Sound in Los Angeles in 1946. Its first product was the D101 15-inch woofer, and the D130 followed in 1948. Altec objected to the Lansing name, so the company became James B. Lansing Sound, and later simply JBL.

After Lansing. Lansing died in 1949, and William H. Thomas took the company over and cleared its debts. JBL drivers went into Fender guitar amplifiers, the Paragon stereo cabinet of the late 1950s and, through Capitol Records, recording studios.

Harman. In 1969 Sidney Harman's Jervis Corporation bought JBL, and the L100 bookshelf speaker followed in 1970. Harman calls it the best-selling speaker system of the decade. Harman sold JBL to Beatrice Foods in 1977 and bought it back in 1980.

Today. JBL is part of HARMAN, which Samsung Electronics has owned since 2017, and it marked its 80th anniversary in 2026. Harman's acoustic research was long led by Floyd Toole, who came to Harman from Canada's National Research Council here in Ottawa.

Which JBL is which?

Classic L series (1970s to 1980s): the L100 of 1970 and its successors, and two-ways such as the L46 of 1982, with its 8-inch 117H woofer.

Studio monitors: the 4310 of 1968, and the 4311 and 4312.

HLS series (late 1990s): such as the HLS610 and the HLS Center, with polycarbonate dome tweeters on horns.

Northridge N series (about 1999 to 2003): the N24, N26, N28 and N38, the N Center and their II versions, with titanium-laminate tweeters.

Northridge E series (2003 to 2005): from the E10 to the E100, the EC25 and EC35 centres and the E150P and E250P powered subwoofers. JBL's support pages say the E30, EC25 and E150P were made in Mexico.

Portables and today's ranges: the Link 10 and other Link speakers of 2017, the Stage series, and the L100 Classic of 2018.

Buying used JBL: what to check

Foam surrounds. A factory-authorized service centre says older JBL foam surrounds dry-rot, faster in humid climates, causing weak bass and buzzing. Repair shops add that JBL woofers have a tight voice-coil gap, so re-foaming needs care.

Tweeters. Play every tweeter. Owners report dead tweeters on 2000s Northridge models, and some original replacement tweeters are no longer available.

Crossovers. On older models, ageing crossover capacitors can dull the treble.

Link portables. Run a Link 10 on its battery to see how much capacity is left. JBL rated it at about five hours when new.

Fakes. JBL warns about counterfeit portables. A genuine one has a flush power button and an embedded grille logo.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
