Witam! Mam pytanko odnośnie zmiany głębokości obudowy w projekcie Troelsa ( http://www.troelsgravesen.dk/CA18RNX.htm ) Pisze on tam coś takiego:
"These SEAS CA18RNX drivers hold the classical coated paper cones, but here with a 39 mm voice coil former allowing greater power handling compared to CA18RLY's standard 1" voice coil. Overall frequency response is better for the CA18RLY, but despite a somewhat whobbly midrange they sound smooth, detailed and throw a punchy bass. Smoothing the midrange further took at lot of components and the sound? Not better, thus this simplistic crossover only smoothing some peaks in the 8-10 kHz range.
17 liter/driver makes F3 = 47 Hz and you may increase cabinet volume to e.g. 42 liters and have F3 = 43 Hz. No problem, the CA18RNX can easily handle 21 liter. F3 = 40 Hz will require 24 liter/driver, a total of 48 liters. To do so, increase cabinet depth and maintain height and width + placement of drivers on front panel. Also maintain a port tuning of 42 Hz."
i teraz mam pytanie ponieważ chce zwiększyć głębokość z oryginalnych 270mm do 300mm. Czy ja taką zmianą zyskam lepszy bas nie tracąc nic ze szczegółowości czy lepiej nie ruszać oryginalnych wymiarów obudowy?
