And for SSA, it is more meaningful traffic as well. For example, if a rush of people come to the site all at once after being linked from a larger site, that increases your traffic in the short term. But is that helpful over a long period of time? Not really. Several studies have indicated that "swarm" traffic is not a good thing, but consistent growth is great. I look forward to better and better results here.

Congrats! Pics?

The responsible side of me thinks you should stick with engineering. It is a mentally challenging job with high financial rewards. At the same time, my free spirit side says do whatever comes to your mind. I am an engineering student and I love it. Math, physics, gym, and computer science have always been my favourite classes, and now I am actively involved in three of those categories. Sometimes it just takes a while to figure out what you want to do. If I had gone to university right out of high school, I would have wasted a years worth of tuition, so take your time and find something that fits.

I would love for CDT to do an 8/3/1 set so badly.

Lol, I got a funny email from a friend who is a troll. "Who is this SSA and do they have a website?"

Greetings Rob. Stick around for a while: you have great taste.

I prefer Second Cup and tea over coffee.

Any cyanoacrylate based glue should do fine. http://www.partsexpress.com/webpage.cfm?&a...p_ID=3&SO=2

It shouldn't be that much of the end process either, especially if you're making a quality, affordable sub. Don't pay attention to him I mean, show me an affordable subwoofer that doesn't use widely available stock parts and look similar to many other subs. The appearance really shouldn't matter much, and me personally, I prefer that look.

They should be posting results on the springfling website in the near future (springflingcarshow.com). If you need to know soon, send an email to Doug (organizer) at [email protected] or you should be able to get the results from IASCA over the phone at (386) 322-1551

As far as port noise and vent velocity, that is perfectly fine. I think you'll find that a fairly long port will be required (almost 30" long) to reach an Fb around 35 Hz.

They are great amps, but I was told by a friend with Carver that there was a conflict between PG w/ their Xenon line and JL Audio w/ their R.I.P.S trademark.

Break it down into sections. Top section of the T: v(1) = l*w*h v(1) = 20" * 48" * 9" v(1) = 8640"^3 Bottom section of the T: v(2) = l*w*h v(2) = 20" * 36" * 6.5" v(2) = 4680"^3 Total volume v(t) = v(1) + v(2) v(t) = 13320"^3 v(t) = 7.71ft^3

Here is an interesting thread that might get you on your way: http://www.soundsolutionsaudio.com/forum/i...?showtopic=2690

Almost forgot about Memento and Equilibrium. Absolutely stellar movies.

The port came out quite nice and your wood work looks pretty good. Now what are your plans for finishing it? Good looking enclosure!

I have two invites left to oink.me.uk. Anyone interested?

I thought it was upload, download to a server. Where as Kazaa, Morpheous, excetera are upload, download from random people on the internet who happened to be online at the time. Nope. Sean whatever-his-name-is was a lowly college student who could never afford the server costs that would be involved in that. For example, I pay around US$80 for a dedicated server; 512mhz RAM, 160GB HDD, 100mbps (which is actually capped closer to 50mbps, but still very affordable for the bandwidth), and is totally unmetered. You would need several 100 of these to host the type of traffic that Napster was doing back then. When I get another invite, I'll send one your way. All of that stuff is on OiNK just waiting for you

Looks good so far, Aaron. People are naturally going to call it other subs because of the affordable stock parts, but I look forward to seeing and hearing more!

Just a few thoughts of my own here. Yes, increasing the length of the coil will increase efficiency; it increases BL. However, it can also increase Mms, which will decrease efficiency. There is a point of diminishing returns where you are much better off to increase BL and, conversely, efficiency by adding to the "B" portion of that equation. A positive effect of adding length to the coil is increasing Mms (yes, it is positive as well). Increasing Mms will also lower Fs, which is very handy for those who dig their low frequency response. The last negative effect of increasing L is the increase in inductance, which impacts your high frequency response and your transient rise response. For subwoofers in general, I hate efficiency ratings. If I'm using a subwoofer, I want something that can produce low frequencies adequately in a small enclosure, and here comes Hoffman's Iron Law to trounce on my dreams. I would love to increase BL or drop Mms to increase efficiency, but this will also be damaging to my Fs. If I'm buying a subwoofer, I honestly don't care how efficient it is; there are several high efficiency subwoofers that sound awful from the inherent damage that a low Q subwoofer can audibly produce. Good stuff all around!

No, a copper coil should decrease power handling minimally.

From my previous experience with bandpass enclosures in a vehicle, it is usually best to have the peak that you're seeing (which is primarily courtesy of the interaction with the front chamber) with a 3dB drop down to the Fc of the rear chamber, then a ~18dB/octave slope at that point so long as your bottom end is sufficiently fat, for lack of a better term. From where you are now, this can be achieved by dropping Fb a little bit and decreasing the rear chamber's size minimally. How much you change these will vary dependent on the efficiency gains you are willing to give up that are inherent with a bandpass enclosure. I highly, highly, highly recommend using a flared port, particularly with a small box driver like an Rl-i 8; doing so will allow you to use a smaller diameter port with shorter length will keeping vent velocity lower. I don't have any of the 8" RL-i t/s handy right now so I can't model something specific up immediately, but I think you will find your next project to be a very entertaining one. Predicting cabin gain with a sealed enclosure is relatively easy (even in a car, it's not too hard) but predicting cabin gain and modeling any consistency in that regard with a bandpass enclosure is quite challenging. Personally, I have had success in few trunk cars using the suggestions I listed above. My girlfriends Grand Am is seeing a similar treatment right now and everything is sounding good so far. There is a caveat to the suggestion I made above, and that is simply that if you end up with in vehicle response where the lower end is actually rising, you will probably be very disappointed by the perceived "sloppy" sound that is natural to the human ear at lower frequencies.

OiNK > * There is no other torrent tracker or p2p that I like as much as OiNK. It's also a nice gateway to other private torrent sites once you become a power user there. From OiNK, I have gained access to thedvdclub.org, torrentleech.org, bitme.org, etc. Private torrent trackers are a beautiful thing, especially if you have a 100mbps seedbox

I couldn't agree more with Sean. If you're just wanting an approximation for a "daily application", then just use whatever the manufacturer publishes. If you're going to test a product with the goal of producing any measurements worth comparing to the manufacturer's published information, then it only makes sense to test in the same conditions.

You came to the right place. Greets!
