Here's my first enclosure design. It's an MLTL designed for the Mark Audio Pluvia 7 Full range driver. I'm going for a single driver speaker with no crossover, but will add a baffle step compensator if needed. I used the Leonard Audio TL program for the design. Please look over the model output and tell me what does or doesn't look good.
Also, I would love it if someone would put my specs in Martin's model and see if they get a similar result, or if it shows any "defects" in my design that the LA TL model doesn't detect.
Some of the model results are attached. I understand that the main goal is a flat SPL curve over a broad frequency range, but I must admit that I'm not sure what to look for in the other plots.
Okay, my MLTL specs are as follows:
Driver: Pluvia 7
Main Tube: 150 cm2 constant cross section x 87 mm long.
Driver Position: 42 cm
Port Position: 70 cm
Port Dimensions: 17 cm2 x 9 cm long.
Stuffing: Main tube from 30 mm to 70 mm only, density 3 kg/m3
Pluvia 7 Specs:
Revc= 7.200 Ohm
Fo= 67.863 Hz
Sd= 50.270 cm²
Vas= 5.543 Ltr
Cms= 1.545m M/N
Mmd= 3.356m Kg
Mms= 3.561 g
BL= 3.968 TM
Qms= 2.391
Qes= 0.695
Qts= 0.538
Levc= 35.057u H
No= 0.241 %
SPLo= 85.843 dB
Pwr= 22 watts
Nom X max= 4mm
1 way
FYI, all outputs were plotted with the default amplifier power of 1 watt.
Thanks,
Eric
