AB Acoustics Step Up With EAW KF730 And KF740 Line Arrays

Established in 1989, the company headed by Huw ‘Buzz’ Evans and Rob Ashton had been running EAW’s popular KF750 as its premier system for the past eight years.

But trying another brand to mark their excursion into line array technology they immediately found the system wanting — particularly in the lower frequencies. “However, we had heard EAW’s KF730 via another PA company — and really liked it; the bottom end was far superior to our previous system.”

And so in March this year the company invested in 12 of the compact KF730 line array elements, complemented by six SB730 subs, which extend the response down to 35Hz.

But with the busy outdoor season looming they also realised they needed the larger footprint of the KF740 system, with its four phase-aligned 10in woofers, for wider site coverage — and four months later invested in 18 enclosures, along with the dedicated UX8800 4-in/8-out digital system processor to run with their arsenal of existing 2 x 18-inCH SB1000 subs.

 “This not only gives us the capability of running nine-box-per-side hangs but also rigging compatibility with the KF730 — which could also be used as outfills for the larger events,” said Buzz.

The KF730’s were purchased initially for the Urdd Eisteddfod (Youth Festival) in Swansea, followed by the National Eisteddfod of Wales, while the KF740’s made their debut for AB Acoustics at a park in Pontypridd (for Ponty’s Big Weekend).

Promoted by the local Rhondda Cynon Taf County Borough Council, when the local authority expressed their delight with the system’s containment, having carried out propagation tests, Huw knew he had bought wisely.

AB Acoustics then fielded the KF740’s for the Cardiff Big Weekend and received highly favourable comments — particularly from The Feeling’s sound engineer.

The KF740’S system’s busy duty cycle has since continued with 2011 BBC Proms in Caerphilly, in front of the magnificent mediaeval castle, featuring Wynne Evans and the BBC National Orchestra of Wales.
“We are delighted with our EAW investments, which are really proving their worth — and so are our customers,” stated Buzz.
