L-Acoustics KS28 debuts on David Gilmour tour

A full L-Acoustics K1/K2 rig with brand new KS28 subwoofers was recently supplied by Clearwing Productions to provide sound reinforcement for David Gilmour’s North American tour.

The Rattle That Lock gigs represented the official US debut of the KS28, which was introduced just a month ago at Prolight + Sound and deployed by Clearwing on a North American pilot programme for the product.

With its extended frequency response down to 25 Hz, reduced weight of 174 lbs and three decibels greater output than its predecessor, the KS28 “is a marked improvement on the SB28,” according to Gregg Brunclik, president and CEO of Milwaukee-based Clearwing.

The full system complement for the 11-date, four-city tour (Los Angeles, Toronto, Chicago and New York) included left and right main PA hangs of 14 K1 over four K2 per side, each backed by an array of 12 K1-SB subs. Outfill arrays were comprised of ten K1 over eight K2 per side, with left and right extreme outfill arrays each made up of 12 Kara. Two dozen KS28 subs ground-stacked double high across the face of the stage and driven by six LA12X amplified controllers (in two new LA-RAK II racks) filled out the show’s low end, while an LCR delay system of three hangs of six K2 covered the farthest seats in the largest venues.

Sound engineer Colin Norfield was also impressed with the KS28: “They are half-again as loud and 30 pounds lighter,” he said. “They have a tighter, deeper and richer sound, which helped to enhance David’s show. The KS28 is great all-round and I’m looking forward to using them again on the next leg of the tour.”

In describing the overall sound of the system, Brunclik added, “In addition to being 3 dB louder, the KS28 is both more musical and more concussive than the SB28. The combination of the new sub with the already established K1 and K2 boxes in the hands of a truly great engineer like Colin is an immensely powerful tool.

“He did an awesome job mixing this, by the way. The sound of this tour was nothing less than stellar. It’s been quite some time since I stood in front of a rig grinning like a schoolboy.”

Gilmour is best known for the decades he spent with classic rock pioneers Pink Floyd, and his guitar work on tracks like “Money” and “Comfortably Numb” have been named as ‘among the best in the history of rock music.’

With Gilmour’s entourage soon heading to Europe and the UK, international sound reinforcement duties will switch back over to Britannia Row Productions, which supplied the mixing consoles and monitors for the North American leg.
