Hi all,
My next weekend project is to make new baffle boards and replace my ancient Altec 414Z's (two per box) with reconed 2231A's (2235H kits). The enclosures are about 8.7 cu ft in gross volume. I hope to add enough fibreglass fill to create a virtual 9 cu ft volume.
Can someone with 4350's measure their vents for me to use as a starting point? Also, from the data I have, it looks like the 4355 had elbows in the vents, maybe someone knows why?
I am also looking for a recommended Fb tuning frequency, I think JBL used 30 Hz. I am trying to achieve lowest F3 possible. Suggestions anybody? I plan to drive them with 400 Watt/4 Ohm monoblocks.
