///M5

It is gorgeous outside. I should be fishing, but I have a shit ton of work to do.

What are you panelling?

I did but it was ugly so I cut it down. Next year I will put a bit more creativity into it.

i refuse to give money to wallmart, even if it is a bad business decision

Please stop shopping and posting until you actually do what you promised you would. Measure and think, post and you will get recommendations. At the moment you are about to waste a bunch of money.

yea i really want low bass with a lil of loudness to it if that make sense will it be better to run sealed or go porter with a low tuned box? I still doubt you care about the "lows". What sort of music do you listen to?

gun, hell a lasso would work

10 minutes ago out my window: Mom If I opened the window it would hit the fawn And two travellers

I'd disagree. Sealed will play lower; however, I really doubt that Tony actually cares about lower.

should be tired, but I am not

22rms keeping up with 1600wrms, ROFL.

Lol, just looked at my insurance to pay it and realized that the M5 with bigtime coverage and umbrella is only $27 a month. Less than a $1 a day. Going to make it harder to sell.

Stop yelling and use words and sentences.

what settings are important?

My day got real busy at a pretty funny time.

Lasted three days on the new hours, eh?

jeez, time flies

Estimate the lows? Impossible? Lol, so what makes you assume you know better then? Ever built an enclosure that is too small and listened to it? I haven't used that 8, but every ID sub that I have played with preferred the enclosure on the larger side of their recommendations. Their marketing department is eager to put smaller enclosures as recommendations, but that doesn't mean they really should be recommended. Could I be wrong? Sure, but I really doubt it. Go ahead and build an undersized enclosure for your 8's and see how it is. I'd guarantee though that a single 10 in an optimized box will give you nicer output and definitely act more like a sub. Take a step back and look at the information that you given us: 1) Lightest setup possible 2) Lightest setup possible 3) Aesthetically pleasing, which your design is around a .6cuft box 4) SQ 5) Using the subs that "you want to use" I repeated light since you called it paramount and seem to get excited if anyone offers anything other than uber light. The problem here is #5 doesn't go at all with the rest of the list.

Gettin' hungry

Everything is a compromise. When playing with things, shut off the mids and only listen to the tweets. Then you only have one polarity switch you need to make, once you add the mids there are many more combinations of phase to deal with.

I ask questions so people can get answers, most are predecided and want someone to just reiterate what they like even if it is the wrong answer. I won't do that. Exactly why I rounded down to 10lbs or 66% of the weight of MDF. It won't be quite that light though. .9 came from ID direct: http://www.imagedynamicsusa.com/manuals/iD/ID8D2%20V.pdf .35-.45 is recommended. I used the lower of the two and then added the volume of the two drivers which gets us to .8-.9. I did read that you said .6, but again you ask to have a nice sounding system and for that it means the sub is supposed to play the lows. Putting two of them in that small box won't help with that. As I said, no need to discuss this in this thread, you did say that for autocrossing you'd take it out anyways. In the street 10lbs is meaningless. Not worth it here though as I don't care, I really just want to help with your actual goals. Let's just ignore this portion for now and try to understand how we can put together a light solution for you.

Procrastination,

Hey, don't be so defensive let's just discuss this. You asked for other ideas, so you are getting them. So let's look at this weight more closely that you want to keep to a minimum. MDF, 3lbs/sq ft, sure Trupan may be 80% of the weight. The box for the pair of 8's will be around .8-.9cuft, so for easy math lets say 1ft (cubed) which is only .67 cuft but with 5 sides the enclosure will weigh 15lbs with MDF and a whopping 10-12lbs with Trupan. Each of your subs is more than the enclosure. If weight were really such a concern, I'd really like to know why using one driver with nearly the same enclosure size and the nearly the same weight wouldn't be actually your goal. You use the word "paramount" but then add another driver that is equal to the weight of the enclosure. Note I was very conservative on the enclosure weight. 10lbs would mean Trupan is only 2lb/sq ft and I didn't add any weight for the baffle side of the enclosure. Your box will weigh more than that. On top of that I only computed it for a .67 cuft enclosure and not the actual .9 or so that you would need. One other comment. Your claim your goal is SQ, but yet you are willing to sacrifice the single most important portion of setting up a sub by putting it in a sub-par enclosure from a rigidity standpoint. I realize this is for a compromise, but then saying that you concerns are for the utmost SQ is a bit oxymoronic. *I will also argue that you won't feel the difference of the weight by saving 20% of the box weight in your car as an under 10lb change isn't much, but that discussion we can have elsewhere as we should first address your concern with the box. Easy to test the weight difference though. Go take a lap and then add 2 gallons of gas and take it again, it will be the equivalent of having the sub box be made from 3/4".

You may have seen me harp about mounting locations and such for different drivers. Everyone wants to know where to mount their tweeters for instance, without describing what they have for a car or for tweeters. I have never met two different tweeters that sounded their best in the same mounting location. Some like to be near on axis, some completely off, it all depends on what sound you like and more importantly the roll-offs of the individual driver. While I almost always prefer my mids on axis, I can't say that I have ever really heard a tweeter in a car that I prefer on axis. Obviously I haven't tried them all though.
