Descriere

Used EAW KF-750/SB-750F se compune din doua subwoofere 2 x 18” si doua speakere de banda larga KF-750F. Fabricate in SUA, aceste boxe sunt deosebit de puternice ajungand in maxim SPL la 145 dB la un pic de 2400 W

Importul se face numai cu pre-comanda, plata anticipat si pot fi livrate in maximum 8 zile.Produsele sunt second-hand si au fost folosite de la achizitia lor de noi de o singura firma care a organizat doar evenimente coorporate indoor. Se prezinta in stare tehnica excelenta, iar estetic 8 din 10

O simpla reconditionare a vopselei exterioare si a grilajului metalic protector din partea frontala vor fi suficiente pentru ca aceste minunate speakere sa arate ca noi.

Disponibilitatea este de 4 topuri si 4 suburi. Pretul exprimat este pentru un set format din 2 topuri si doua subwoofere.

O multitudine de amplificatoare Crown, LabGruppen, Crest, etc se califica sa amplifice acest sistem pasiv. Alaturi de un procesor de sistem adecvat de tipul 2 in 6 out veti obtine un veritabil sistem PA gata oricand sa satisfaca cele mai exigente cerinte. Se vor folosi pentru topuri cabluri Neutrik NL8 speakon, topurile fiind pe 3 cai, iar pentru subwoofere Neutrik NL4 Speakon.

The KF750F Technical spec

The three-way full range loudspeaker system shall incorporate 2x 12-in LF transducers, a 10-in MF cone transducer and a 2- in exit/4-in voice coil compression driver HF transducer.

The LF drivers shall be mounted in a vented enclosure tuned for optimum low frequency response and separated vertically.

The MF driver shall be mounted on a large-format horn and shall be coupled to a phase plug whose geometry exactly matches that of the driver. The HF driver shall be loaded on a constant directivity horn with a nominal coverage pattern of

35° (h) x 35° (v).

System frequency response shall vary no more than ±3 dB from 48 Hz to 18 kHz measured on axis. The loudspeaker’s subsystems (LF/MF/HF) shall produce a Sound Pressure Level (SPL) of 103/109/116 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 139/141/145 dB SPL on axis at 1 meter. The subsys- tems (LF/MF/HF) shall handle 2x 600/400/200 Watts of amplifier power (continuous) and shall have nominal impedances of 2x 8/8/8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of multi-ply void-free cross-grain-laminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be a 2x Neutrik NL8 Speakon. A total of eight 4-position flytracks (4 each front and rear) shall be provided. The front of the loudspeaker shall be covered with a powdercoated perforated steel grille.

The three-way full range loudspeaker system shall be the EAW

model KF750F.

The KF750F 3-way tri-amplified full range system contains many new EAW technologies that make it a powerful concert touring sound reinforcement tool. Its Acoustic Singularity™ design aligns the three subsystems along a single axis so the KF750 acts as a true point source, greatly reducing temporal

smearing of transient events and improving overall clarity and

impact.

Since the large mid frequency horn contains both the high and low frequency subsystems, the overall package is just 31-in high. Still, the KF750F provides consistent wideband pattern control in both the vertical and horizontal planes.

The LF subsystem includes two vented 12-in woofers mounted in the MF horn’s upper and lower walls. This spaced configuration extends vertical directivity well into the LF pass-band to minimize midbass build up below the array.

The large MF horn loads a specially designed 10-in midrange cone whose geometry exactly matches the rear of its phase plug assembly. By developing the driver and phase plug as a single unit, pathlength discontinuities within the MF pass-band have been eliminated without compromising the directional qualities of the source.

The 2-in exit/4-in voice coil HF compression driver is mounted on a 35° x 35° constant directivity horn mounted coaxially within the MF horn flare.

The KF750F’s 15°-per-side trapezoidal enclosure features eight 4-position flytracks (four each front and rear) that accept industry-standard flyclips.

The KF750F is designed to create arrays with optimized coverage in both the horizontal and vertical planes to cover audience areas ranging from 200 to 80,000 people.

At just 31-in tall and 190 lb. per module, KF750F arrays are smaller, lighter, more efficient and, therefore, more powerful than those built with other systems. These smaller, lighter arrays are easier to fly, require less truck space and permit more open sight lines to cover any given venue.

The KF750F works with a companion downfill module, the KF755F, to provide full range nearfield coverage below the array. The KF750F’s smooth power response produces remarkably even SPL levels throughout the coverage area, allowing

it to be used for nearfield coverage when necessary.

Applications include:

Concert Tours

Performing Arts Centers

Houses of Worship Theaters

TECHNICAL SPECIFICATIONS SB750F

FEATURES

subwoofer system

• 2x 18-in woofers, vented

• F version optimized to fly with KF700 Series arrays

DESCRIPTION

A dedicated subwoofer system with 2x 18-in transducers in a vented trapezoidal enclosure. An SB750F enclosure shares the same footprint as a KF700 Series module and is almost exactly one-and-a-half times its height, meaning that a two-

high column of flown SB750’s is exactly the same height as a three-high column of flown KF700 Series modules.

At less than 200 lbs. per enclosure, SB750F’s offers users the flexibility of adding them to flown arrays without adding inordinate weight.

APPLICATIONS

While many users will choose to deploy the SB750F in groundstacked clusters, the system is engineered to work with KF700 Series array modules in flown arrays. Some array configurations allow the creation of dipolar subwoofer ar-

rays to improve pattern contol in the lower octaves.

In addition to sharing dimensions as discussed above, the SB750F features identical four-position flytracks as well as the stacking pad that joins stacked enclosures during both groundstacked applications and transport. Each SB750F comes with 4x cable links of the proper length for arraying with KF700 Series modules. It also uses the same caster pallet (CP700) as the KF700 Series modules. Six year warranty.

Applications include:

Major Televised Events

Concert Tours

Corporate Events

Large Theaters

Large Arenas

Large Dance Clubs
