GM's MLTL with 416-8B

[westend9]

Yeah, the longer I've been on audio forums, the more I've come to appreciate Altec's and the other pioneer's design philosophy of intentionally designing in some leakage and adjusting box size and/or vent tuning to get an acceptable result because even if they could reliably manufacture an airtight product the odds are that the tuning would go away the first time it's opened in any way, so in the scheme of things a wasted added cost better spent on either improved components for pro use or fit/finish to improve 'curb appeal' of consumer products.

Why get rid of the R-13? If nothing else, I'm curious how it works out.........

Ugh! I just had my little reminder program pop up to remind me to file too, though being below the poverty level, yet above the minimum required to file a return, it's just a paper exercise with no tax either paid or owed. Seems like they would make the two $$$ points the same, but apparently their need for keeping their workforce ever increasing is the reason for the spread.

GM, in looking at densities of the R-13 and the OC 703, there is a 2lb. difference (703=3 lbs/cu. ft., R13 =1.0 lbs./ft.). I have installed approximately 4u ft. of R-13 in each cabinet, if my calculations are correct.

I'm sure your Uncle Sam wants a tabulation each year so that, in the future, when he gets ready to pay down our debt, you'll tally the numbers and a different result comes about. I am still on the fence if I should start collecting some of that SS money that my Uncle has been hanging onto for me or if I should trust him to hang onto it for a few more years. I need to get that sorted out in the near future.

One thing I'm noticing, again, after only a brief stint at the accounting desk, is that we are paying a big amount for gasoline. Go figure.

That is only going to get worse. Look for $5.00 a gallon by August !

It seems like gas is more expensive each and everytime I enter the gas station now.

Now at this moment in Holland we pay with a lot of pleasure :rotfl: US$ 9,46 a gallon, but that's not only in Holland the case, these are Europe prices at the moment. We can't wait till August. Nice, nice, very nice :rotfl:

That's why a normal carpenter cost you about US$ 60 per hour, exclusive tax, that's inclusive tax US$ 71,40 per hours. Do you need a new garage to build??

Call me, we have about 4 or 5% unemployment here, so orders are welcome!! :rotfl:

Still over 10% here............

GM, your suggestion of an air leak was immediately dismissed because I thought with all of the PL400 in the joints, the gasketing of the bottom hatch, and the driver's gasket, there could be no possibility of such. Was I wrong.

I've been learning that too.And currently working inside my cabinets as well.Trying to find any potential area for a leak and go over it with silicone.

Still over 10% here............

Up here too ! 9-10 % In these economic times it's nice to be self-employed or own your own business !

Yes, when you're self employed you either have the best boss in the world or the worst boss in the world!:snickerpup:

It's the leaks around hardware and/or poor sealing factory gaskets that most folks miss and why I prefer the NEMA spec neoprene since it's self sealing when you drill through it.

Now you guys have got me wondering if there are any leaks in my Model 19 or Model 14 cabinets. The low frequency response in all of them is amazing--so the tuning seems to be excellent--nice DEEP/clean/smooth/powerful bass. But of course I always wonder particularly with anything audio related if there is room for improvement. After all, Socrates said "the unexamined life is not worth living". So therefore, the unexamined audio system is not worth listening to! Anyways, the 19's and 14's are basically the same cabinet design (just on a different scale) as many of you out there already know. I'm thinking that where the top and bottom sections of the cabs are bolted together might be a potential leak. Is there a good test for air leaks or should I just take out the woofers and horns (to have access inside the cabs) and caulk all the seams where the top sections and bottom sections are bolted together? If so, is silicone (in a caulk tube) a good idea? I've never even checked out the bolts inside either pair of my 19's or my 14's--should I consider tightening them down more before caulking? They don't seem loose now--never seemed to be any "give" to them when moving them around (to where they're presently located). Any other place(s) particularly prone to leaks with the 14's and 19's? Or does the tuning take into account that there may be miniscule leaks--and is the fact that the bass/tuning sounds so great out of each 14 and 19 speaker that I own an indication that I should leave them the way they are? Is there a chance that if the tuning is great now that if I seal some miniscule leaks it could make the tuning sound worse in the rooms where they're located? Maybe the answers to these questions could shed light for others with their various Atlec cabs as well?

I liked no boss so much that I fired myself.

I have memories of when I first became self employed/my own boss--there were days that I decided to take off (on a whim) and thought that "I have the best boss in the world". But I also remember days where I really wanted to finish something I was working on and worked over 12 hours straight without even a lunch break and afterwards thought "I have the worst boss in the world"!

Yeah, but the point is I already know what to expect with 703 and R-19, so looking to increase the knowledge base....................
