Thanks Bill,
I'll double check for leaks again in that cab. I couldn't hear any using my 'stethoscope', but the popping noise did make it kind of hard to hear. I'm guessing that it's not too good for the drivers to be running them into their physical excursion limits like that too.

Ok, so after a brief hiatus where I was so peeved with myself for using the wrong glue, I'm back into it. I've sealed the joints that I can reach with a polyurethane flexible filler and added my drivers and back panel. One of the cabs is all good, no leaks apart from a small leak where I've mounted ...

I really appreciate all the help guys. I'm actually from Australia and did some research to try to find PL before I started but couldn't. So my plan of attack now is to get the back on, run a tone through them and see how I'm doing for leaks. All my joints were pretty much spot on with no gaps so I'...

As I said, too late. I've used this on my 2 Jack 12s.

Too late, I glued the sides on last night. Here's some pics of the glue, one from where it's still in the join, the other from a piece that I took off with a scraper. Here's a link to some info on the glue. http://www.titebond.com/ProductLineTB.asp?prodcat=3&prodline=6 and the pics... if anyone ...

The glue I've used is a polyurethane expanding glue as specified. Bubbles up and expands as per all the information I've seen here. But yes, hopefully I've used enough of it and all the joins are perfectly sealed. I think that I read in one thread about using a straw to listen for leaks, so I will g...

So I was trial fitting the drivers today and wondering about a couple of things. How tight should I compress the gasket? I guess it just needs to be airtight. Should I be removing the rear gasket so that I can screw down directly onto the speaker frame or just be leaving it there and compressing it?...

Ahh, of course. That pesky peak between 2 and 4 kHz on the Eminence 2512. This makes sense to me now.

Thanks

Ok, so a couple of other threads here seem to indicate that high quality finishes will just prove a source of frustration once you throw them in the back of the car a few times. Anyway the build continues apace, more photos below. So much glue, so little wood... I'm a bit concerned about the next st...

Hi everyone, I've got the plans, the speakers and all the timber cut to the right sizes bar a few of the smaller items like the bracing and backplate flanges. I've never built boxes before, although I built some drawers a couple of months ago. So I'm a little nervous about cracking the lid off the g...

Here in Australia we went to metric in about 1966 I think and the imperial is pretty much dead in the water now. I must admit I was a bit surprised to see all the measurements in my new Jack 12 plans in the old currency. Looks like the other tool I'll be needing is the imperial steel rule. Mostly I ...
