After using up almost 9 feet of sonotube on Sunosub I and Sunosub II, I still had a 27" section left over, so what the heck, let's build one more sub!
Okay, boys and girls, here's the 1st installment of photos of my progress on constructing Sunosub III:
I'm using the Tempest 15" driver from Adire Audio (formerly Avatar Audio). Just to recap the design specs for this effort:
1 Tempest 15" driver
1 4" ports 21" long (probably going with a flare port kit) - tuned enclosure to 16Hz
5.75 ft^3 of internal volume
24" wide sonotube roughly 25.25" tall before endcap thickness.
3/4" thickness of MDF endcap on each end to conserve internal volume.
Here we go:
Day 1 - I go shopping 9-13-00
The raw materials:
Photo 1 : Here's the cut pieces of MDF. I went to Home Depot, and bought a 49'x97' section of MDF and had Home Depot cut it into 2 pieces of 28"x28" (I plan on having a 27" wide table top on the sub, and also for the bottom endcap), and 2 pieces of 25"x24" for the internal endcap on both ends. I wound up with some excess MDF as you can see.
Photo 2 : Here's a close-up of the 2 pieces of 28"x28" MDF, 2 pieces of 25"x24.5" MDF, and 1 piece of 24"x24" of plywood (for screwing/glueing in the T-nuts for the driver holes).
Photo 3 : Since I have stuff left over from the previous Sunosub efforts, here's what I picked up - Wood glue, Silicone caulk, beefy 6" table legs, leg mounts, enough 2" 10-24 machine screws (for leg mounts, driver screws) and 8 10-24 T-nuts, enough 2.5" 10-24 machine screws (for the terminal cup).
Photo 4 : Here's a look at the sonotube-like material that was left over from the last two Sunosub projects: 27" of sonotube.
I'll probably take a leisurely stroll on this project. Again, it'll feature some different challenges. I think I'll go with a piano black table top cover, and perhaps use a black sock to cover the sonotube. The top cover will overhang the sonotube by 1.5" all around (I might stick to an overhang of 1" though).
The tune might be asking a little too much for a 5.75 ft^3 enclosure for the 15" Tempest driver, and I might pick up more port noise than optimal, but I'll get to see how adversely port noise will affect the overall sound quality of this subwoofer in normal operating conditions.
