Just ordered Titan 48 plans!

MrHeadfirst · #1 05-15-2010, 04:01 PM

Hey all, I just ordered plans to build a pair of Titan 48 subs from Bill Fitzmaurice. Anyone using these or have any tips before I start building? I cant wait. Ill post pics of the build when im done.

Yeah, I got a tip for you. You better have a permit for an "Infernal Device" from ATF and register with the police in the adjacent forward-facing town before you fire that thing up.

Hopefully you've built speaker cabs of some kind before. Owning a table saw is also a big plus. Sure; they can be built w/a circular saw and a straightedge. You can also cross the Atlantic in a rowboat. Measure 234 times and cut once; small errors are cumulative. Get it all right and you'll blow out windows 2 towns over; all with about 1/2 the wattage of traditional ported or sealed cabs.

What are you going to use for HF? If you do match tops to two T48's which stadium are you playing in?

If you're a gigging musician, 39s are a much better bet from what I can tell. You might want to double check that with your goals.

MrHeadfirst · #6 05-15-2010, 08:06 PM

well...lol, if these things are as stupid mean as you guys say they are, then i have grossly overshot my needs...I am a gigging musician, and i play anything from small bars to medium size rooms to the occasional outside show. I figured they were going to be capable of being loud, but i kind of was of the thinking I can always turn down, but if i built too small, i cant turn up. So the T48's are that crazy loud? my pa system mains are a brand new set of peavey sp2's with the matching bipack amp and i have one jbl jrx 118 powered sub. the sub i have is just plain weak...seriously, its pathetic, so with this build i wanted to make sure i had enough low end to do what i wanted without too much stress. plus i can set my mains on top of my subs and go without stands...at least i thought.
i have been thoroughly disappointed with a lot of different gear, so i decided to try this. I have been reading a lot about bills designs and i am anxious to try them, so i decided to try these. i have build cabinets before and i have the required tooling, so i am confident i can do it without issue. i guess maybe i didnt realize the output capability of these things...just seemed like the t39's might be potentially too small. I dont know...is it unreasonable to be too big and turn them down...i guess id have plenty of headroom that way...lol...right?
thanks for the input guys

use enough of pl premium to keep everything sealed

rpsands · #8 05-15-2010, 08:16 PM

A pair of T39s should be just fine. Each one is more sensitive than each SP2, really as much as 2 sp2s almost.

T48s are HUGE.

Are you using them for PA subs or as a sub in a bass rig?
Best place to ask your question is on Bill's forum

The assumption since you're posting here is that you intend these for electric bass. Whatever your intent for them your questions should have been posted on my forum, before buying any plans, but obviously that ship has already sailed. You should still do so before making any further investment in parts and plywood.

MrHeadfirst · #11 05-15-2010, 08:20 PM

well the other thing i looked at were the dimensions, the sp'2s will fit squarely on top of the t48s without overhanging or anything. i havent started building yet, but i did already buy the plans. hmm

MrHeadfirst · #12 05-15-2010, 08:21 PM

i was using them for pa subs. i will go post in bills forum. im just always on here these days, so i figured id post. thanks

rpsands · #13 05-15-2010, 08:24 PM

Definitely a good idea to post over there. My understanding is gigging band PA, the T39 is probably the best way to go.

You should not be setting the mains on top of your subs on either side of the stage either. Pole mount the mains for optimal coverage, put the subs on the ground in front of the stage.

MrHeadfirst · #14 05-15-2010, 08:25 PM

thanks for the info, im heading over to your website now bill, ill check the forums there, if i need to, ill get the plans for the t39's too. you have helped me plenty of times on here, im glad to be building your speakers.

MrHeadfirst · #15 05-15-2010, 08:34 PM

as in lay them on their side in front? im reading on the other forum now...

rpsands · #16 05-15-2010, 08:38 PM

Yep, and use the V-coupler if you're using two

It's in the plans I think, a little piece of wood that makes the cab horn mouths couple or something like that.

MrHeadfirst · #17 05-15-2010, 08:42 PM

yep, i see it, im reading the attached deal that talks about coupling subs...has the little applet to show how it works. how cool...i never knew. been doing it wrong forever. aghh, man i read about this stuff until i think my head will pop, then i learn something else i didnt know. guess it goes to show youre never done learning.

Wall loaded to one side or the other is usually preferable.

In a perfect world all manufacturers of PA subs would include instructions on how to place them properly. It's far from a perfect world, though. AFAIK not a single one does.

Even worse: they put pole mounts on sub tops to encourage one to place the subs where they absolutely should not be placed. You'd think that sub manufacturers have no clue how sound waves work. Guess what? Most don't.

MrHeadfirst · #19 05-15-2010, 09:15 PM

yeah, no kidding. once i started reading about placement on your site, i realized how wrong ive been doing this. i think im still going to build the 48's, i dont really have space restraints and dont mind packing them around really, and as i read, i find having them placed on stage as you show, wont bother us on stage. im happy to read about that.
im going to read on more about wall and corner placement, since i dont fully understand that yet, looks like to me, with this type of placement, i can really use my stage space more wisely than i have been. thanks a ton bill. one quick question, my mixer has a built in crossover, do i need to put a limit on the low freqs sent to the subs? is that necessary? or can i just let them have everything below a said frequency..say 100hz..or whatever is best?

rpsands · #20 05-15-2010, 09:15 PM

What I should have said is "Read the faq on sub placement"

In most clubs I play in it would not be feasible to wall load a couple of T39s, so it'd wind up v-coupled in front of the stage probably.
