YAMAHA IF-2108 2-way wooden cabinet loudspeaker 8” woofer

Yamaha realized more than 40 years ago that simply building systems around speaker units bought from other manufacturers would not do, initiating a long and arduous but fruitful quest for ideal speaker performance based on original technology. Along the way innovative Yamaha speaker technology has resulted in a number of breakthrough products that established new performance standards in a number of critical fields.

The D 8 is a light-weight, robust 8“/1”, 2-way plastic cabinet for professional sound reinforcement applications. With a variety of suspension accessories and conservative cosmetics, the D 8 is ideally suited to be used in demanding fixed installations.
The cabinet is manufactured from ABS and therefore is extremely resistant against abuse on the road. For low and mid frequencies a DYNACORD DND8200-8 neodymium transducer is used. The Electro-Voice DH3 driver is used for the projection of the high frequencies. The Constant-Directivity HF horn has been integrated into the baffle by CAD methods. The nominal coverage angle of the cabinet is 90°*90°, horizontal*vertical, respectively.
Power handling of the cabinet is 250 W (rated) and 1000W (peak). The maximum sound pressure level is 124 dB, the frequency range of the D 8 is from 65Hz to 20kHz. The D 8 is ideally suited for applications as full-range cabinet or as Mid-Hi cabinet in high-performance small-format active and passive satellite systems.
Every transducer is protected against short-term thermal overload with thermal cutout switches and halogen protectors. In case of a potential thermal overload the power applied to the speakers is reduced to a safe level. The protection exhibits ʽsoftʼ switching characteristics, so no annoying clicks or pops are audible. The circuitry automatically resets after the voice coil temperature has reached a safe value.
Extremely durable acoustic foam mounted to a strong powder-coated steel grille protects the loudspeaker components against any mechanical damage. The trapezoidally shaped enclosure also allows employing the cabinet in monitoring applications. A stable, integrated carrying handle and the integrated stand socket for pole-mount stands allow easy transportation and set-up. A protective cover is available as an optional accessory.

The C4128 is a full range 2 way high sensitivity, dual woofer passive system, compact and versatile specially designed for under balcony applications.

It is designed to provide extended low frequency performance from a compact, vented enclosure. It features advanced technology transducers: two 8" woofers equipped with a 2" voice coil and a 1" neodymium compression driver equipped with a 1.5" voice coil. The compression driver is mounted on a rotatable 90 x 70 constant directivity horn, providing very natural sound reproduction.
The cabinet is asymmetric (15° and 45°) for versatile under balcony applications as well as ceiling/wall installation and floor monitoring operations.
The wide coverage angle and the true constant directivity of the newly designed horn make very easy the coverage of large audiences.
