I am about to embark on building a modular pseudo 434X system approach consisting of some components I have at present and hopefully will have in future. I am planning on having two 15" JBL woofers in two separate enclosures per channel with a third housing the MF/HF/UHF drivers that will fit in between. This hopefully, will allow me to experiment with MF and HF drivers and horns, two way versus three way, etc. without having to build new woofer boxes over and over again, since I am not all that adept at building cabinets.
So, the plan for now is to use finished Parts Express style subwoofer cabinets and merely cut the approprite openings as needed and stack'em.
To begin with I will use 2235H woofers in two 3 cu. ft. boxes per side. I know this volume is not optimal for the lowest F3, but these will be used in conjunction with subs, anyway. I would have preferred to use 2234H's but I haven't got any at the moment.
My question to you T/S software guys is: What would the best recommended FB and venting size and length arrangement for optimum transient response? I have ordered some 4" adjustable vents for starters, trouble is, I am not sure what to ultimately tune the box to. They will likely be crossed over to subs at 40-50 Hz.
Anybody have some thoughts or recommendations?
Charles.
