Ok, another design, this time trying to use all available space AND designing to the absolute constraints of the speaker…
Waveguide of 8cm x 3.5 cm
Rough measurements are
135 + 50 + 100 + 50 + 145 + 150 + 250 = 880
+ 50 + 250 + 50 + 250 + 31= 631
Total = 1551 – err, oops!, got a bit too carried away with the designing there! could have left the last two folds out! I only need 720!
on the plus side, the enclosure’s 315x315x110 = 10.9 liters! and is probably a bass monster if you can get a decent driver
Off to bed, i’ll try again in the morning!
