RÉPLICA PANTALLA AMPEG 18¨
Construidas con las parámetros de la citada pantalla, (medidas volumetria, reflex etc.... pero con un cono JBL 2445H (en mi opinión) superior, al Eminence que sale de fábrica. En las fotografías se puede apreciar, la original y la réplica.
Si necesitas graves, esta es tu opción. Contundencia y claridad.
Nunca han salido de bolo.
Precio 360€. Envío a la peninsula 35€
Por favor, no proponer cambios, que estoy saturado en amplificación
Las especificaciones del JBL
2245H Low Frequency Loudspeaker: 460mm (18 in)
FEATURES:
600 W continuous program power capacity
100 mm (4 in) edgewound copper ribbon voice coil
20 Hz to 2kHz response
95 dB sensitivity, 1 W@ 1 m
The JBL Model 2245H is a professional quality low frequency transducer designed for use in custom studio monitors or other applications requiring high sensitivity and power capacity, as well as extremely low distortion and extended bass response.
To achieve this performance, the 2245H incorporates a new diecast aluminum frame, integrally stiffened cone with foam surround, 100 mm (4 in)diameter edgewound copper ribbon voice coil, and individually machined magnetic pole piece and back plate. Additionally, the cone is coated with an exclusive damping formulation to ensure optimum mass and density.
The 2245H also features a large, high flux, Symmetrical Field Geometry (SFG) magnetic structure. The SFG design, in combination with a Flux Stabilizing Ring around the pole piece, significantly reduces second harmonic distortion and provides exceptionally accurate low frequency reproduction. This motor assembly is optimally balanced with a 25 mm ( 1 in) long voice coil and carefully engineered suspension elements to allow maximum excursion linearity with complete freedom from dynamic instabilities.
Nominal Diameter: 460 mm ( 18 inches)
Rated Impedance: 8 ohms
Power Capacity: (Continuous program power is defined as 3 dB greater than continuous sine wave power and is a conservative expression of the transducer's ability to handle typical speech and music program material) 600 W continuous program
Sensitivity: (The sensitivity rating of JBL low frequency loudspeakers is based on a signal swept from 100 Hz to 500 Hz. rather than the conventional 1 kHz single frequency test signal, since these drivers are usually used below 800 Hz Therefore, usable sensitivity of the 2245H may be substantially greater than that of loudspeakers with higher published ratings) 95dB SPL, 1W@1m
Frequency Range: 20 Hz to 2 kHz
Frequency:
