Sal.cunoaste cineva acest difuzor?MB12N351 de la rcf.in regim fulrange pe un filtru pasiv 12db/oct intretaiere la1,5hz va duce 650w? Mersi

Daca vei folosi un HPF ( macar 12db/oct ) setat la 65 Hz si atacat cu semnal curat, da. Dar sant curios ,ce inalta vei folosi sa duca puterea necesara , taiata la 1,5K , si sa aibe si un raspuns cat de cat liniar ???......(asta in cazul in care faci boxa pe 2 cai )

salutare si mersi de raspuns,da boxa e pe doua cai driverul este d2500ti de la selenium:Selenium's D2500Ti-Nd-16 is an ultra high-quality compression driver for professional use wherever high SPL and low distortion are required. A high flux density neodymium magnetic assembly dramatically reduces the driver's size and weight compared to conventional ferrite structures. The pure titanium diaphragm with IPF® (Impregnated Polymer Fiber) surround is embossed with a "snowflake" pattern for maximum linearity and minimal breakup. An injected phase plug is optimized to eliminate undesirable phase cancellation problems, and the aluminum shorting ring lowers distortion and reduces the voice coil self-inductance. The D2500Ti-Nd-16's voice coil uses CCAW (copper clad aluminum wire) wound on a high temperature polyimide former. A precisely engineered diaphragm structure and alignment mechanism allow for easy, reliable, and cost effective repair in case of diaphragm failure. The D2500Ti-Nd-16 is recommended for use in all sound reinforcement system applications. Standard 1-3/8"-18 TPI screw-on mounting. Available in 8 ohm and 16 ohm versions. Specifications: *Power handling: 80 watts RMS/160 watts program (with recommended 2,000 Hz, 12 dB/octave crossover) *Voice coil diameter: 1.7" *Throat diameter: 1" *Impedance: 16 ohms *Frequency response: 1,000-22,000 Hz (no crossover) *SPL: 111 dB 2.83V/1m *Magnet weight: 4.05 oz. *Dimensions: Diameter: 3.15", Depth: 1.5", 2.2" including threaded "nose". Dar este pe 16ohm si nu stiu daca va rezista mai bine ca si acelasi model dar pe 8ohm.poate imi poti spune un de se va muta punctul de taiere cu acest driver de 16ohm.multumesc.

Alegi varianta de filtru pe care vrei sa o folosesti, introduci datele si i-ti calculeaza automat valorile de care ai nevoie pt frecventa de taiere aleasa ( preferabil 2Khz ) , dar mai trebuie sa-ti calculezi rezistenta pe inalta.

Ce amplif vei folosi pe aceste boxe ?

mersi pentru programul de calcul,folosesc un alto mac 2.4de 2x575w pe 8ohm.
