About the Alcons Audio L-Series Loudspeaker
The Alcons Audio L-Series Loudspeaker comprises true line-array systems intended for use as vertical arrays in stacked or flown configurations. The LR7/120 and LR7/90 models are loaded with an RBN401 pro-ribbon driver on a Morpher lens, delivering 120-degree dispersion with seamless coverage through an all-natural cylindrical, Isophasic wavefront. All Neodymium drivers contribute to an excellent performance-to-weight ratio, while SIS pre-wiring ensures high damping and reduced distortion when used with ALC. The companion LR7B bass system features a double-tuned concentric band-pass design with a single 12-inch long-excursion Neodymium woofer in an ultra-compact, stackable and flyable cabinet. The LR14 extends the range as a further passive 2-way line-source system suited to both portable and permanent applications. All cabinets carry Durotect protective coating.
Alcons Audio L-Series Loudspeaker — buyer FAQs
What is the Alcons Audio L-Series Loudspeaker and how is it typically deployed?
The Alcons Audio L-Series is a range of passive 2-way true line-array loudspeaker systems designed to be used as vertical arrays in either stacked or flown configurations. They suit both portable touring setups and permanent installations. The range includes full-range line-array cabinets such as the LR7/120, LR7/90 and LR14, alongside the LR7B matching bass system.
What driver technology does the Alcons Audio L-Series use, and why does it matter for coverage?
L-Series full-range cabinets use an RBN401 pro-ribbon driver mounted on a Morpher lens, which produces an all-natural cylindrical Isophasic wavefront. This design delivers up to 94% frontal radiation and 120-degree horizontal dispersion with seamless coverage, while all-Neodymium drivers keep the performance-to-weight ratio high, an important consideration for flown or portable array applications.
What is the LR7B, and how does it relate to the rest of the L-Series?
The LR7B is a double-tuned concentric band-pass bass cabinet designed to match the LR7 line-array in both permanent and portable use. It houses a single 12-inch long-excursion Neodymium woofer in an ultra-compact, lightweight cabinet that is both stackable and flyable, either with an LR7 array or in a separate bass array. Like the full-range cabinets it uses SIS pre-wiring and carries Durotect protective coating.
What should I check when buying a used Alcons Audio L-Series system?
Check that the pro-ribbon HF driver is undamaged and producing clean output, since ribbon drivers can be sensitive to misuse. Confirm whether the unit is an LR7/120, LR7/90, LR14 or LR7B, as each serves a different role in a system. Inspect the Durotect cabinet coating and any rigging hardware for physical damage. Used L-Series listings on this page carry a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
Who makes the Alcons Audio L-Series, and where does it sit in their product range?
Alcons Audio is the manufacturer. The L-Series represents their line-array loudspeaker range, spanning compact two-way cabinets such as the LR7 variants through to the larger LR14, alongside the matching LR7B bass system. The range covers both portable production and permanent installation markets, with passive filtering intended to allow economical powering across different system scales.
