Hi all, long-time lurker, first-time poster. I've decided to take the plunge into sonosub Heaven, after pouring over Patrick Sun's site and many others. My Tempest arrived today, the PE 300-794 should be here Monday, 3/4" MDF is eagerly waiting in the garage, and I have a 6' piece of 24" sonotube gracing my dining room. I have come up with these numbers in LspCAD:
Volume327l
Ql 7
Qa 30
Fill 25%
Length 42.5 cm
Min Dia 15.2 cm
Res Freq 17 Hz
SAF Max Ht 4'-6"
(Okay, so the last number isn't in LspCad, but it should be
)
Edited to add airspeed in port is 16.39 m/s at 14.8 Hz, and down to 10 m/s at 20 Hz.
The size and tuning is very close to Pat's Sunosub II. My living room is 15' long x 19' wide with a 13' min. vaulted ceiling. You can see the see the 1 meter and in-room graph
