hey mate,
workmanship looks good, couple of questions.
did you think about using the volume below the box to increase the box volume?? having the timber there looks like wasted space to me.
other thing was, with the subs at 180degrees to each other they will cancel each other like mofos. will seriously hurt your db (which looking at a wall with serious cable) is what im assuming you are chasing??
would have been better off with a wall and a slot port (ive done loads of these) or a bandpass box of some type.
Hey ferdie,
This is like a 4th order wall. I made it this way due to weight. Since I drive it everyday. I didn't want to overload it.
Also I wanted something different. There used to be a car with the same kinda wall, but with bigger subs and in a bigger car. It use to get 150db. I know this kinda setup is more popular in usa.
I know a big slot port would have gotten abit higher DB, but, this way its more musical. Plays a better range of freq.
ah ok so the cab becomes a calculated "box" volume in the scheme of things??
your right on the slot port limiting the frequency, although a really good amp will help "control" the sub so it sounds ok with music, and a different "slide in" port is what we use to make for music, then pull it out for dB drag...
still think the cancellation would be epic as they are sharing both the front and back volumes, they will be having compression hitting each opposite cone.
ive been out of the game seriously for a couple of years, techniques could have changed...
have you had it on a meter yet?? i will be interested to see how much i can push out of my new daily mightyboy with a single 12" and 5000rms (DD 3500 carbon fibre cone sub and Earthquake amp)
