Ugh redesigning the wheel.....
I play bass in a few bands. Where I live (NYC) backlines, especially for bass, are very common and I almost never need to bring a bass cabinet anywhere. There are rare exceptions, however. I have a 4x10" but the thought of bringing it out for a show in a cab/car service at this point seems ridiculous. So i'm looking at possibly constructing a TL806 or TL806 style cabinet to have something more manageable I have thoughts/questions I need to get out:
PLANS FOR REFERENCE:
https://robrobinette.com/images/Guitar/ ... _plans.pdf
CAB CONSTRUCTION/DIMENSIONS:
A lot of what i've read says that the important parameters to the design are 1) the internal volume and 2) the port area and depth. If i'm being honest a lot of the internal bracing in the original plans seems to be overkill ESPECIALLY for my light usage. The plans say the TL806 has a gross internal volume of 1.3 cu. ft. My math says that the gross internal volume is 1.28 cu. ft. and the net internal volume if you subtract out all the bracing is more like 1.23 cu. ft. Is it ridiculous to think I can use less bracing as long as I adhere to approx 1.23 cu. ft. internal volume?
PORTS:
The original builds ports out of lumber. There are two ports that are 4" deep and 5.63 sq. in. each (ignoring the optional center port). Nowadays we have the internet and the easy option of cheap, lightweight plastic ports. Is it ridiculous to think I can use prefab ports so long as I have an equivalent area of 11.25 sq. in. at 4" depth?
INSULATION:
The plans specify lining the inside with 3" fiberglass insulation, but it seems like a lot of people skip this. Any experience with/without insulation??
SPEAKER:
Of course the originals are designed for an EVM-12L but I know people switch this up. I hear people like the Eminence Kappalites? Any other possible speaker recs?
