Nope, just finished. I doubt that they will all get together until June.
Aw man...I couldn't take that long of a wait. When my last two were "finished", the leak test was completed immediately after they were rolled into place for their first gig (with no paint). They did have some nice sheets tossed over them. :lol:

Looking forward to your report on how they all sound.

I'll probably be splitting them all summer at that venue. Hopefully, at one point I'll be able to stack 'em up.

Bruce (or others, for that matter): This does sound like a stupid question, but having never built Titans before:

I'm assuming you cut all the panels at once, so as to not have to move the TS fence, correct? Did you intentionally cut your panels too long, so that you could go back and put the proper angles on the ends as you assembled? I've done up my cutsheets in Cutlist, but I used the "finished length" for the cuts. I'm assuming I should go back in and add a half inch or so to the length of all internal panels, so I can take them one by one and put the proper angle on it?

Here is what my cutlist looks like ATM: Please LMK if it looks OK (does not include the driver spacer, access flange or braces). This is for a 24" (23" internal) T48:


Required
24.000 48.000 Side 1
24.000 48.000 Side 2
24.000 23.000 Panel 1 (Top)
16.500 23.000 Panel 2
25.000 23.000 Panel 3
11.000 23.000 Panel 4
17.500 23.000 Panel 5
22.000 23.000 Panel 6
30.000 23.000 Panel 7
48.000 23.000 Panel 8 (back) (plans show this panel as 48" on the "cut sheet" but 47-1/2" in the diagram on page 19...weird)
6.000 23.000 Panel 9
24.000 23.000 Panel 10 (bottom)
12.000 23.000 Panel 11

I received my second 3015LF today and it's a keeper. Next paycheck, I buy the BB and get to cuttin'!

Mike, if you dig a bit deeper in the plans - you'll see that the parts sizes listed on the cut sheet are already larger than the finished parts. The actual sizes are in the body of the plans. You'll be making beveled cuts that will take them down from the cut list sizes.

And yes, definitely make all cuts at once, because the panel widths won't change - only the length.

Well I'll be darned...you're right. :oops: But hey, at least I was thinking about panel length before I started cutting. LOL! Thanks again, Bruce.

Thanks!

They are coming out from under the wraps this Saturday. If any of you Texas boys want to come check 'em out.

We are doing a benefit for a lady with cancer - it will be the new band's debut. River City Driving Range (yep, it's a driving range - with a really nice patio and a really big stage) in New Braunfels.

Unfortunately, I probably won't be able to v-plate the subs. The set up there is really weird and they will be 4 feet below the stage on uneven ground - I'll just stand 'em up next to each other.

I emailed you, Bruce. You're right up the road from me; I gotta come check things out. 8) All four subs, just grouped together will still be very formidable! Looking forward to it.

Well, we had all four running last night. We weren't hammering 'em, but had a nice, fat volume for the country band, the young rockers, then our geriatric bunch.

Unfortunately, the was no opportunity to really get a sound check as there was other performers starting up as I was about to check it out - I was hoping to maybe use an RTA, but what I got was about three minutes out front running a Steely Dan song and made a few changes on the PEQ inside the Presonus board.....(I did use my new iPad to control it all).

There was no sound check before any of the bands - we just went cold. My first impression of the two extra subs was that the sound was fuller. Pretty much like when I went to the second pair of OT12s - not just louder but smoother and fatter. It just seemed like the subs weren't working hard at all. Neither sub amp ever got close to hitting the red.

Overall, I was very pleased. I may consider moving my high-pass down to 45hz. I've always run at 50 because of the content of the music and wanting to protect the drivers as much as possible.

The second test will be in two weeks as I will be splitting the subs and v-plating both sides at an outdoor venue.

Thanks to Miked who came over and videoed a bunch of the night. I look forward to seeing and hearing it. If we weren't too embarrassing, I might even post a video.

Awesome man. Ditto that on the sound check. When I was younger and didn't mind rushing setups, I often didn't do them them. Needless to say now I prefer a slow setup and a sound check.

Glad everything went well! Unfortunately, it seems that sound checks and pinking a room have become a thing of the past even when you're the only act. An act is expected to set up, sound great, and leave.
Our lead singer is a fair drummer. He plays and sings the first two songs while I dial in the FOH and monitors. That's our sound check. It's not the best scenario, but it's safer that hoping for a sound check. Venue managers aren't as accommodating as they use to be.

Fortunately, I don't run into that very much. Seems as though I do a lot of outdoor stuff for some reason.

What saved us is the fact that I run the monitors post fader and I get a full mains mix in my wedges....as do the other guys. If it sounds good in the monitors, I know it's at least close out front. But, I'd still rather have a sound check.
