I'm gonna guess mitered and glued. Should be just as strong as any other joint in the box. Possibly stronger since the miter allows more surface area to glue.

I'm gonna go out on a limb (though not way out) and say that your system is not at a stage where adding processors is the ticket to great sound. Get the install to the "excellent" stage. Upgrade to active fronts. Once all that is done might it be worth considering going with a processor like the 3.sixty.

That was kinda my point. But at least there's something there after almost a year.

...Or at least some Ben Afflek look-alike is

Try the 20 setting rather than the 200.

SVC 3 or 12 or DVC6.

The title says it all. I live here in Vegas but had to work/didn't realize the show was going on until it was over.

You have to account for the air displaced by the sub AND the port. The volume displaced by the port is "dead air" for tuning purposes. You're going to be looking at around 1.9 or smaller once you install the port.

It's a standard formula. Yes it works. And yes, everyone who has designed a ported enclosure has used it. Even if they used a computer program to design the box, the program uses the same formula.

Its a variable Q subsonic filter circuit. The idea is that by setting the Q of the SSF high you can get both a boost just above the half power point of the SSF and a SSF all in one circuit with one control. Both the freq and the Q are adjustable.

Kinda wish I still lived up that way...

At least most of ya are from the nice part of Canada, eh.

Fully understand. Back in the day (2003-2004) you guys could and would make the make the living one dead anyway.

denim- Anywhere I can upload the file to link to here. It's only about 14k.

You should post it here x2 please wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee I'll head upstairs right now. It's on the other computer.

That same equation tells you that the amp running into the lower impedance will usually lose more power as heat and will usually be less efficient. Usually. You have to account for the on resistance of the output devices and the on resistance of the switching devices in the power supply. With a low enough resistance, the amp running into the lower load could be more efficient.

This isn't a maybe. You've bought their BS hook line and sinker. You probably did see an increase of voltage at the amp, but then the RCAs you replaced were garbage. If you had compared the Tara labs cables to a set that were other than crap you would not have noticed a quantifiable difference. There is no measurable difference in any spec that will have an audible effect between a basic set of decent cables and the super high $ cables that Tara Labs is so proud to boast about. They can't explain in actual quantifiable terms why their cables are any better than rest. Nothing more than "because we said so." If that explanation is good enough for you then send my the money you were planning on spending on the "because we said so" cables and I'll send you cables that will be as good as any you can buy and tell you that they are superior so you can fee good about yourself.

You guys ask how it could be done? "Do not swerve to hit or miss an animal" is a direct quote from the pre-departure brief given in the missile field to any driver going from one area to another. The cops and maintenance folks would roll a vehicle about once a month doing something stupid. I didn't think it was possible but one of the cops managed to roll a Humvee end-over-end on a road where the speed limit was supposedly 25 MPH.

Old subs had tiny motors and used tiny amounts of power in comparison to stuff today. Power handling and total motor force have gone up dramatically. As such, moving mass has gone up but motor force has increased proportionally more. The moving mass of modern subs is not a huge factor any more.

Any updates on when this will be??

Most people would call this a SQ sub. Even old school subs were capable of getting loud by daily listening standards of the sane person, but nowadays if you say "it's loud" people expect to be able to run a ton and a half of power to it and win comps. This is a sub for those of us that don't think like that and can appreciate the ability to run a small amp on the sub stage again like the old days. People that build a system for music, not comps. That want to be able to still use the vehicle with the system installed. That don't want to HAVE to upgrade the alternator. Thanks, Jacob...I think...you just either really simplified or really complicated my sub decision for the next car. Probably the latter.

The amp that does the power at 4 ohms *should* draw less current, however if the amp design is optimized for that particular load, the difference shouldn't be that great.

The enclosure does a lot to overcome the inertia of the moving mass of the sub. Consider also that for the same amount of power with the same motor assembly, the larger sub simply won't move as far as the smaller sub. The period of the stroke is determined by the frequency of the signal being reproduced and if the sub doesn't stroke as far, it is moving slower than the one moving farther in the same amount of time. Inertia is proportional to the square of the velocity and the mass in motion. Just to run some numbers as an example: We'll use a motor force of a constant of 1 (to keep it relatively simple) and a 60Hz tone. We'll also call the effect of the enclosure as a constant and equal for both drivers. I'm using the Mms of the iCON series of drivers because they are conveniently located on this site. iCON 15 1=262*a; a=1/262 v=(1/262)*(1/120) i=262*(1/31440)^2 i=2.65x10^-7 iCON 10 a=1/190 v=(1/190)*(1/120) i=190*(1/22800)^2 i=3.65x10^-7 Based on the numbers above, for the same amount of power, the 10s actually have more inertia at the corner than the 15s.

Most EQs worth having have a line driver built in. Even if you were to run an extra line driver, it would get its signal from the EQ (or the other way around). You would only need enough line level outputs to run a signal to the EQ. From there everything gets its signal from the EQ.

Because neither of those take mechanical limits into account. You can usually get pretty much all a sub has to give with less than RMS, and definitely get loud enough to damage your hearing.
