I know this is an old thread, but when using three tweeters did you wire them in parallel or in series?

How did this cabinet end up? The build was impeccable. The selected driver was a little out of spec. I hope there was a happy ending to all this effort. We are left hanging... :conf: Actually I was just recently able to get the time to haul the cabinet outside to get some good half space measuremen...

And I don't think I've ever used a clamp on a sub. Other than the spring clamps and the W braces.

Do not fear the clamp!

When you say you are building 24" T48s is that 24" panel width or outside dimension? I wouldn't bother with clamps shorter than 12". The ones you are going to using the most are 12", 18", & 24" lengths.

Yes it was.

Matched up? Like how? Was the sweep taken with everything closed up? :fingers: For starters, that peak above 100 Hz is awfully large for any horn sub. Yup with everything closed up. By matched up I mean the frequencies at which the peaks occur are very close to my hornresp sim. I took a impedance s...

Well I got this thing finished up today. Here are a few more pics: http://i.imgur.com/Kuc8oax.jpg http://i.imgur.com/4kXOyeE.jpg http://i.imgur.com/mTZF0fA.jpg Here is an impedance sweep I did using my DATS, I'm not an expert on interpreting these things, but it matched very closely with my Hornresp...

Well its at least starting to look a little more complete. I trimmed up all the edges:


Here it is with the access cover temporarily in place:

I'm getting close to getting this thing complete, here is the last of the 15" wide panels getting glued in: http://i.imgur.com/ZK6JSIE.jpg Horn mouth brace going in: http://i.imgur.com/r2FMGzt.jpg Almost ready for the other side panel: http://i.imgur.com/TtaTbjY.jpg Getting ready to glue on the...

More progress:

I too have built a jillion cabinets. Occasionally I use yellow glue for some styles, but none of Bill's. It can be done, no doubt. If I were doing it with a horn though, I'd caulk the joints. It's not so much about the strength (pl is stronger, I tested it) as it is the air. Even a pinhole will aff...

Got some more time to work on the THT tonight. Here I am gluing in the driver mounting panel: http://i.imgur.com/OSPobpU.jpg Here is a close up of the glue line, for you Titebond naysayers :-) http://i.imgur.com/7xrJ10p.jpg Fifth panel being attached: http://i.imgur.com/4VfBprU.jpg I'm getting a lot...

Made some more progress on the THT. The one big drawback to the driver I'm using is it can't be reverse mounted, so Rockford Fosgate gets -10 points. I just made an adapter plate which the sub front mounts to. Would have been easier if I had just gotten a driver that can be reverse mounted, but appa...

Have you considered the pressures involved and the inflexibility of Titebond? One of the properies of PL is that it does have some flex. While it may be true Titebond holds just as well if not better on a well prepared surface... but over time wood flexes and expands and contracts and Titebond won'...

This is the time that you need to use it. And, as an experienced woodworker, you also know the there is no such thing as a "perfect" joint. If it could be done, it would be a recommended practice. It isn't because you cannot cut a "perfect" air-tight joint with wood. FTR, PL Pre...
