EAW At The Heart Of New System At Cultural Center In Estonia

Integration firm Heliart OÜ goes with QX300 Series full-range loudspeakers as well as RL18S active subs in project at the Saarepeedi Cultural Center.

A recent sonic upgrade project at Estonia’s five-decade old Saarepeedi Cultural Center with the goal of high SPL, consistent coverage and high vocal intelligibility saw integration firm Heliart OÜ deploy Eastern Acoustic Works (EAW) QX300 Series full-range loudspeakers as well as RL18S active subwoofers to bolster the low end.

Located in southern Estonia near Viljandi, the venue is noted for presenting Estonian folk music as well as theatrical and dance events, seminars, rehearsals, musical acts that include choirs and live bands. The new house system utilizes EAW QX364 (60 x 45-degree dispersion, h x v) loudspeakers flown left and right, with four EAW RL18S cardioid subs concealed in custom-built structions under the center of the stage.

“The large 4-inch voice coil compression driver with constant directivity horn is surrounded by two pairs of phase-aligned high power 10-inch low frequency drivers,” says Priit Kivimägi, CEO of Heliart OÜ, about the QS364. “This extends the pattern control to lower frequencies and therefore keeps the energy off the walls and ceiling, and in the audience area. This really helped combat the acoustical challenges of the building’s large painted concrete walls and high ceilings.

“All this is packed into a visually pleasing, small footprint enclosure. What I like most about the QX Series is its symmetrical design,” he adds. “Linear phase response and full-frequency spectrum originating from a single source makes this a predictable and easy to operate system.”

The venue also had an outdated electrical system designed to meet the needs of a modern sound reinforcement system. “The last thing we needed was harmonic currents wandering around the electrical system resulting in audible hums or other unwanted noises,” Kivimägi explains “For this project, a new electrical system was designed based on the requirements of the sound and lighting equipment resulting in a dedicated audio-only distribution box with full automation.”

The loudspeakers’ power options (single, bi- or triamp mode) were also a benefit. “The triamp configuration was the key to keeping the overall impedances, speaker cable losses and amplification cost in perfect balance,” he concludes. “The QX300 is truly a state-of-the-art system. In addition, the system’s low idling power consumption is a great feature from an energy savings perspective. We are thrilled with the results and so is the community.”
