Titan 48x8 build

[Bill Fitzmaurice]

Do you think that having good quality line conditioners would help take care of skethcy wiring?

They're a waste of money.

mmmkay, finally some progress. Got some 7ply birch from Menards for 11 bucks per 48x24 sheet on sale so I bought all they had...which was only eight sheets but the pre cut sheets save a lot of cutting and a lot of cussing trying lug around full sheets of wood which sucks cause I always mess up at least one corner lugging them around! Also I was looking at the specs regarding the 3015lf's and relized I dont have add reducers Christmas in July.

Note the markings regarding the cuts for angle boxes (cutting above panel nine and 11) Should I cut the 45 degree angels to match the initial measurements of 4*4 and 9*9 or do I cut at the 1/2 mark made above the initial marking...or somewhere in-between? Hope that made since, see the pics below for clarifications. My assumption is that I cut to match the initial measurements and that the 45 degree slant for the top and bottom panels (1) will then follow the 45 degree slopes on the side panels.

If I understand your question, you're asking about truncating the box past the corner reflectors, right? You need to cut from the outside of the 1/2" strip. Remember, your corner panels are cut to the same width as all the internal panels, so they need "book-ends" formed by the two side panels.

Alternatively, you can measure those corner pieces to be the full outside width of the box, cut on the inside of the 1/2" line, and slap them on as a cover piece. As long as the box is airtight, either way achieves the same goal.

If I'm answering the wrong question, pretend I just said: "Hey, nice job so far! "

The yellow is the corner panel, either 9 or 11.

The yellow is the corner panel, either 9 or 11.

cool, so i cut the line that measures 1/2 from the original line..reflecting on the question i guess that does make the most since..

thanks for all of your feedback guys...three traced out with five to go!!

Slowly but surly the herd grows in size! All eight are done but just wouldn't fit in the picture. Hopefully now that the bands done for the season and some of my other projects are wrapped up I can progress a little faster.

Quick question about the anchors: Since I will be using the 3015lfs in this build I will only need one anchor per box. However, I am building eight boxes and it seems like a waste of nice BB just to make eight anchors for 15" subs. So, does it really matter what the anchors are made of so long as I stick with 1/2" material?

Addendum: same question regarding the 3/5 and 4/6 bracing. Does it matter what material it as so long as I follow this specified thickness.

Thanks!

What's an anchor?

[chenry78]

What's an anchor?

The driver anchor, required to support the driver mounted onto the baffle (panel two).

[Tom Smit]

For the anchor, 5 ply minimum (spruce, pine, fir).

For the braces, even 1/4" thick (3 ply) will do. But that can be tricky. Wood that is 5 ply typically is the recommended, for ease of install.

Multiple, opposing plies are the secret to strength and rigidty.

Started some actual construction today.

Two issues but nothing major:

The first: even though I read the plans probably 30 times I still forgot to drill holes through the two sides so that I will have a guide on the opposite side of each side piece to follow when screwing the panels in. Oh well, Ill do that today with the tops already affixed!

The second: (see pic below) Yours truley bought precut 24"x24" panels ( so Im sure you know where this is going) thus, one end-to-end measurment of the panels is 23 7/8", which is tolerable. However, the other end-to-end measurement is 23 5/8. Soooo Now I have to go back and take an 1/8th" of each precut 24x48" panel that I have.

Neither it a real big deal I guess, so I would say " so far, so good"

[chenry78]

Tops are on and now im going back and putting my guide lines on the opposite sides for fasteners. Little bass-akwards but it worked all the same!
Hope to have the baffles done next week. Cutting and installing everything, times eight, takes for ever, oh well it will be worth it in the end!

Heres some shots of panel two. Gotta do some routing tomorrow and hope get them mounted this weekend. Not real good pics here but kinda gives some angle shots...Eight panels down...whole bunch left to go!!

[chenry78]

more pics...sorry i get bored at work and it only takes a couple of seconds to snap 'em!

Got more wood today. 4'x2' birch panels were only $11 bucks today...bought all they had...again, for the third time

[Gregory East]

4'x2' is some handy stuff for 24" wide T48 I bet. You guys with BB on tap have no idea how lucky you are.
