Well, based on my software (bassbox pro)and on my first assumption, standard yung box dimensions niya for a 15" subwoofer driver. Maganda yung graph yung lumabas flat yung response niya pero cguro kung sa actual may kaunting descripancy because of inherent room modes pero over all ok. Existing box itself was tuned @ 28 Hz.. not bad.. basta 4 ohms (series connection ng voice coils ng driver ha... ). Good luck.....
sir toquero, finally found a JBL GTO kaya lang model 1502 diba 4ohms yun (series connected) i was looking for the 1504 model kaso wala daw available nun locally. the cost of the 1502 is 4,3k mall price kasi...
sir tanong ko lang kaya kaya ng existing sub amp plate ng DTX 4.15 yung JBL GTO 1502 kahit 4 ohms yun? kasi eto yung specs nung DTX 4.15 sub:
cabinet: Medium density fiber board contruction (MDF)
enclosure type: front firing vented box
finish: woodgrain vinyl
driver component: 15"
impedance: 4-8 ohms
power handling: 300 watts
freq range: 40hz - 220hz
variable cut-off freq. control: 50hz - 180hz

speaker level input: 2.5v rms max.
power source: 220 vac
sir kakayanin kaya ng amp plate yung JBL GTO 1502? hindi kaya iinit ng husto ito? baka kasi masira yung amp plate eh...
thanks!
