The XTi Architectural Series point-source technology is particularly valuable in distributed sound reinforcement applications where most listeners are located off the system axis. It is suited to distributed applications in semi-reverberant spaces where a single reflected source offers a more coherent radiation field with less reflected virtual sources than a traditional dual horn-woofer combination.

Point-source systems are also adapted to proximity applications such as stage monitoring, front-fills and under-balcony fills. Their radiation characteristics yield excellent phase response, total wavefront coherency at all frequencies, and axi-symetrical directivity which produces identical coverage patterns in both the horizontal and vertical planes and a sound field stable over the entire frequency spectrum. The result is a natural, studio monitor sound quality and the aural sensation of transparent sound and an even sonic performance within the enclosure beamwidth.

The 8XTi cabinet is the most compact coaxial model of the L-ACOUSTICS® Architectural Series and operates on a frequency bandwidth of 65 Hz to 20 kHz. This response can be lowered to 32 Hz with the addition of the SB18i subwoofer.

The 8XTi enclosure contains a 1.5’’ diaphragm compression driver coaxially-loaded (for HF directivity control) by an 8’’ low frequency transducer in a bass-reflex tuned enclosure. The internal passive crossover network uses proprietary third order filters. The linearization and protection of the transducers is defined by the drive parameters contained in the amplified controllers.

The coaxial transducer arrangement produces a 100° axi-symmetric directivity output along with a smooth tonal response free of any secondary lobes over the entire frequency range.

The wedge-shaped and streamlined cabinetry, its rigging and colour options make the 8XTi suited to the permanent installation applications where visual constraints require a discreet integration and colour-matching according to architect specifications.

Made of high grade Baltic birch plywood, the cabinet features 4 M6 inserts for Omnimount® 30.0 series fixtures and can be either mounted with the complementary pole-mount socket EMBi or the ETR8XTi bracket for flown applications.The 8XTi is driven by the L-ACOUSTICS® amplified controllers in the following modes:

• ‘‘FULL RANGE’’ mode for standalone use of 8XTi at nominal bandwidth ([8XT_FR], [8XT_FI] or [8XT_MO] presets)
• ‘‘HIGH-PASS’’ mode with 100 Hz high-pass filter to possibly associate the complementary SB18i subwoofer (same presets as above with ‘‘_100’’ extension)
• ‘‘HYBRID’’ mode for hybrid configurations featuring the complementary SB18i subwoofer ([8XT_SB18] preset)

For each mode a distinction is drawn between [FRONT], [FILL] and [MONITOR] presets as they respectively match front of house, distributed applications and half-space loading operating conditions. The performances of the 8XTi enclosure depend upon the choice of preset and physical system configuration.
