Hi Folks,
I'm working on a set of open baffle speakers consisting of a pair of 15" subs , 6 mids in line configuration and a single tweeter per side. I've be playing around with these of and on for a while and will soon be building properly.
I've uploaded some pic including the edge response and the actual design. I'd appreciate it if someone could give me some advice on them. Am i on the right track or are there some points on which im way off.
Not there will be actively crossed and i should be able to even out the 2db bump in the mids with a band pass filter (i think thats the right term?)
Here are some pics and the xl baffle info.
15" skytronic qts 0.92
4" Wharfedale qts 0.52 picture with 0.25" wharfedale tweeter note the removable magnet on the wharfedale - this allows a certain altering of t/s parameters.
Edge response woofers (2) mid (6) tweeter (1) Physical design note the tweeter is slightly offset i may have to roll off the outer drivers at a lower frequency by i'm aiming for between 3 and 5 khz i'm think it might be possible to use a small horn to improve tweeter response i's fs is 1360 khz

SUB MID
Driver Resonant Frequency (Fs - Hz): 30.00 90.00
Driver Electrical Q (Qes): 1.19 0.63
Driver Mechanical Q (Qms): 4.11 2.84
Driver Equiv Volume (Vas - liter): 178.00 3.20
Thermal Power Limit (P - VA): 250.00 75.00
DC Resistance (Re - Ohm): 5.80 4.80
Pk-to-Pk Excursion (Xmax - mm): 6.00 3.00
Effective Cone Dia. (D - mm): 320.00 75.00
sorry about pics - dodgy webcam used and some of my link might be a bit weird.
