ok , m-am gandit la un cub cu latura de 45 cm ,volum interior in jur de 68l,cu un singur port bass reflex in spate, cam ce dimensiuni ar trebui sa aiba portul? ,ar fii valabila incinta? ms. :smt001

NU iti recomand sa faci un cub Construieste o prisma paralipipedica cu urmatoarele dimensiuni (aprox.): 48X42x42 cm iar difuzorul sa-l plasezi nu in centrul axelor de simetrie de pe o fata a prismei ci putin deviat fata de origine cu vreo 4cm. Portul pt incinta bas reflex trebuie sa aiba sectiunea de circa 25% din aria membranei difuzorului, iar lungimea in jur de o treime din adancimea boxei.

Inca un sfat util: dupa ce ai decupat rotundul unde plasezi difuzorul prinde-l inauntru chiar in dreptul pozitionarii difuzorului urmand ca dupa aceea sa plasezi material fonoabsorbant din jurul in prejurul lui. Astfel se mareste presiunea acustica, adica SPL-ul cu circa (1,5-1,8)dB/W/m, iar puterea acustica radiata de incinta cu circa 0,048W.

Iti recomand doua porturi de sectiuni mai mici decat unul de sectiune mai mare. Un port se utilizeaza de obicei la difuzoare cu diametre pana in 25cm. Bineinteles, asta nu e o regula.
