1). is the equation for using precision port (flared) correct? how do you manipulate this equation if you are using 2 ports? Chris Tsutsui, maybe you can help me here because they are what you used iirc. im using a pair of 4" flared kits, and dont know how long to make them.
the equation is:
8466.4 R^2
---------- - 1.463 R = Lv
(Vb) Fb^2
Lv = port length in inches
Vb = volume of box in ft^3
Fb = tuning frequency
R = radius of port
2). i have a 1-input (1 red and 1 black) binding post, but the tempest has dual voice coils. how do i connect them? im thinking that after i attach + to + and - to - (for parallel connection, right?), i could strip the wires so i can tape or sauder (sp?) them to another wire that would be going to the binding up. will this work?
im feeling pretty good about this project. i have everything i need!...except for the sonotube : ( i'll get one after i get some money. the only reseller in town wont sell me anything smaller than a 12' section.
p.s.
3). a quicky: a 24" sonotube refers to the outer or inner diameter?
