Yesterday & Today:
I worked on the sub a little yesterday, but as I only got up at 5pm
and went out at 7:30 to see a mate, I didn't really get much done.
I then managed to miss the last train home, so had to doss down at a mate's. Never made it home until 6pm
At least I had a good time and enjoyed myself. Lucky there is no real target to hit (well, not for 10 days and that's AGES away!
)
Worked on the sub a bit this evening, but gave up at around 11 as I had to cut panel 9, but couldn't really start up the circular saw at that time of night.
As you can see, I have already installed the 6/12 brace, as I wanted to ensure that it was attached solidly with screws. Fitting the panel before I installed panel 7 was the only point at which I could do this. I actually planned to fit all of my 6/12 braces with screws, but every time have been stumped as the 5/6 brace was in the way... in this build I have opted for 2 braces due to the shockingly bad wood, which left me with access so that I could screw in the 6/12 brace (which is the only single brace, in order that it matches my other T30 slim). You can see the screws going into the 5/6 braces in the following pics.
I have been continuing with the BB reinforcement strips, so that when it is time to seal the sub, I don't have any issues with screws stripping the wood.
The braces are also BB, again so that the screws will grip. This was working well, until I hit the upper 7/x (?) brace - the screws just didn't want to bite! I eventually had to settle with a screw about half way along and then I used some big blobs of PL to close the holes (you can see all this on the very first pic in this post.
I have also been running out of nice big bits of BB, so one of the 7/x braces was made from some BB that had a angled cut running along it. The other was made after using PL to glue two strips of BB together to make the required 3 1/8". I didn't use the method in the plans of cutting the BB at an angle to increase the size of the glue line, as I figured that the braces usually stick to the panels with just 1/2" and that holds, so it follows that a split down one of the braces with a 1/2" glueline should also hold.
There was also a shocking void at the corner of panel 7 (where it joins 6)... again you can see that I have injected it with PL to strengthen it. Not ideal, but
this build never was!!
Above is a shot from the back of the sub. The strip of wood next to panel 8 is the reinforcing strip waiting to go in, but this needs to be installed AFTER panel 9, or I might not give myself enough space. Another advantage of having built some of these before is that you can now usually visualize these problems before they occur. Of course the odd one still gets through and then it's
time.
Finally a question or 2. My reinforcing strips are secured with screws through the rubbish wood and into the good wood (BB). I have some in the driver chamber which I have tightened right into the wood (NO pilot holes here as the wood is so soft!). Do you think I need to seal these with a blob of PL, or would they be airtight already? Here's a shot of one of these screws. They seem to be sitting very snug, but is this enough?
I am also worried about using my Berry iNuke for all 4 subs... I understand it isn't the best amp, but it's cheap!
I read on a forum where they did a comparison with a Kam class D amp (possibly same internals as the Sync amps) and they found that it may drop the output when running both channels close to the limit. The post is
here. I am therefore thinking of running half my subs on channel A of my 1st iNuke, and then the other half on Channel A of my 2nd iNuke. I could then run the tops on the 2 channel Bs. Can you envisage any issues running this way? Any advantages?
Thanks for any input. Looking forward to tomorrow... I think I may be able to get the side on if I have a really good day, although I will be taking time to do some jobs now that will save time later (like duratex the mouth whilst the access is good). Shit 2am AGAIN... late start tomorrow I think
Gonna need some good beer after working with that stuff. 
Nothing a big gob of PL won't fix! That screw isn't that important anyway, it's just adding a bit of extra bite to offset the 'grip' that is lost thanks to the veneer.
The build speed increase I attain with every completed cab is a very nice bonus!
or crossed over 
TBH if he is at a party, I will probably run full open with the DEQ holding back the signal... if he isn't, I'll let the DEQ run on unity gain and control from the amps (I know that everyone else is cool and respects my kit).
Don't know what it was but after 3 hours of shivering whilst under my quilt, I started to feel better (probably the paracetamol working). A few hours later and I felt good enough to get panel 9, the 8/2 braces and panel 10 installed.
