Nah mass is too far of a drive for me, plus I'm doing rust work on my car right now so everythings taken apart. Can't do any long drives till I get this inspected. You should come to the one on the 9th...bikini show :naughty:

The big Sanford show is worth the drive. I may or may not hit the one in 2 weeks depending on how quick I can get decide what I'm going to do next, get some new recone parts and build a new box.

I'm thinking of giving up my back seats for a couple months and going big.

It was kind of funny, everyone was expecting something really crazy because the box is so big, But I got a 139 on 800w in a box that can play 20hz to 60hz. It honestly did better than I thought it would. Just wish i could have made it a even 140. Next time i'm just going to do a burp box on the full 3000W the subs can take and see what I can get out of it.

Yep I remember seeing that car. I was expecting some big numbers out of it cause I thought it was a huge 4th order lol. You should give a 4th a try, they get loud and sound great once you take the time to tune em. Mine is flat from 25-50 and gets very loud for a single 12. Comparing it to other setups I've heard that have been metered I would say it puts up close to a 140 (depending what frequency I do it at). I got my second obsidian in 2 days ago so I'll be building a big 4th order for them with a nice fatty kerf to help against any port noise, plus I got 2 batteries off of exo today so I'll be able to run my 2200 at .5 FTW

idk, i've still got the problem of small cones in a big airspace, but I think that a couple of 6th order bandpass boxes would be about the best that I could do with those drivers. They get stupid quiet as soon as they go into any sealed enclosure, they sound really fantastic sealed, but just not loud at all. I think that I could get a 155 with them though on proper power. I really should get something not so SQ oriented though, but thats not going to happen before july rolls around.

I don't mean to burst your bubble but a 55 seems kinda far fetched on a pair of 10's...unless you turn the entire rear of your vehicle into a giant 4th lol. Not saying it's not possible but it wouldn't be easy at all.

If you don't already have some I would get some batts as well. A big alt is nice but if you don't have a battery bank to back it up when you go over that 300A limit your voltage is going to bomb and bomb hard

55 is a bit of a stretch without armor plating and bullet proof glass, but who knows? True horn has a lot of potential so if you could do compression chamber way at the back and have the mouth comppletely sealed off like a wall it would pobably be very efficient.

I do think the horn box was bad ***. Definitely performed well considering you only had 1 sub hooked up and how much power on tap.

3hp is good for 1500W music all day long povided you watch excursion.

Fun show though, shame I blew up both of my subs with a dismal number to show for it.

My current box is 1 cube sealed 2.8 ported with 50 in^2 of port tuned to 40. My next box is gonna be 1 cube sealed ~3.5 ported with 50 in^2 of port tuned to 37-38hz. Most people would say not to tune so low for a bandpass, but my car is so peaky in the high 40's that it evens out the response, so I can focus on making the low end loud and not worry about the highs. The most musical box was the same 1/2.8 setup but with 2 4" aeros tuned to 35. Very flat response with great low end. Of course, it all depends on your vehicle, so these specs might **** in your car. If you make a 4th you gotta be ready to play around with it a bit.

I didn't bring the pathfinder yesterday because it's not inspected at the moment. But I would say it does a 140, comparing it to a 144 that my friend does. For one 600w 12, it's very impressive, also considering I'm running a stock alt with no batteries in the back (which I will have installed very shortly)

With some work I would say a 50 but it would have to be a pretty high frequency. When you're dealing with low cone area it's hard to get it to be loud and musical at the same time

Build the right box and those 10's should get you to a 150, but not in anything as big as you had yesterday. Try a stock class box, below the glass. I was doing high 149's with a pair of 10's and 3k in my old Blazer, no reason you can't do that in a wagon. I had maybe 50 hours into the box and the testing to see that number.

No, it would be really hard to do anything bigger than that thing is. I picked the two largest enclosures you can make and stuck one on top of the other, but hey It got me some great bandwidth to get it low. This time I want to see just how high of a number I can get before the coils melt. The problem with not doing a wall in that car is that the cabin gain peaks at around 20hz, with a smaller peak at around 34hz, thats just too low to get a good number with tens without taking up a significant amount of airspace.

This is probably due to tuning or phasing issues, and I doubt it reflects your true peak. Half wave of 20hz is @ 27 feet


Measure your cabin corner to corner (where the meter sits to furthest back corner) divide that by 1165 fps (speed of sound), then divide by 2 (half wave). This should be close to the target you want you peak.... The large SUV's generally peak in the high 40hz range.

I would say 150 is a good mark to shoot for. You will need to create a lot of sawdust to get there.

After all the big runs I ended up leaving at around 2:20 or so. Was starting to get hungry and didn't feel like sitting around watching everyone go through the lanes again lol. Might of felt like staying if I had my own vehicle there but since I was just spectating it got kinda boring

I tried that this time actually, and didn't really get the results I was looking for. The horn was tuned to 58.3hz (I doubt my cuts were accurate enough to bother with the .3), and thats what i did my run on. (second run was 20hz just because I knew it wasn't going to get any better than that.) It's 10 feet corner to corner. 1165 / 10 = 116.5 divided by 2 = 58.25 temperature and flex any box space probably threw that all off, but this time I'm going to try something different and go with what I can measure as a peak on a mic. I wish I had a real calibrated RTA to use, but I'm still new to this game so I figure I might as well try all the silly things I can and learn from it while I've got no shame.

I don't think temp would make your score change that much. As you get higher up in loudness it starts to count. Nothing wrong with running the A/c a little before your run, though

You called it, I just tore the box apart and took the cones off. Looks like a scraped a coil from over excursion @ 20hz. It's just a small scrape so i think it will be ok, but it's weaker now. Pretty sure i'm going to burn it next time. Maybe i can find some 15" cones to put on them.

I really think your over thinking this a bit. Build a box of a normal size, and built to spec or just a little bigger. Depending on your goal, if your looking for musical and be able to burp it then tune the port to the mid to upper 30's and go from there. If your looking for musical only box and listen to rap and that other bass kinda music then tune to the low 30's. If it's gonna be for burps only then start the tuning in the low 40's and go up from there.
To be honest, competitors that put way too much thought into the science behind waves and such don't seem to hit as high as they want on the meter. I've talked to several over the years that know a lot about the physics behind audio, and always get beat by guys starting out that know nothing about it. Getting louder is all about testing and building different enclosures, testing various sub and amp combo's.
Leave the science of it all to the veteran competitors building Extreme class concrete filled bandpass vehicles and just have some fun and learn it all as you go.

The problem with tuning high 50's with the box you had is that the sound isn't coming from the back corner but the front so pathlength to the windsheild is very short then since the box isn't walled off from the back you get a wave bouncing off the back then up front so no telling what that's causing to gain and cancel. That method is quite accurate and I got it from a good source. Not a replacement for testing, but it gives you a ballpark of where you'll have an easier time getting a good peak.

Those coils will go for a while scuffed up, but will probably fail quicker, particularly if you keep rubbing them.

Robot Underground has OEM Audiopulse cones in 12 and 15" (also possibly 12" LA/honeycomb nomex), and OEM coils, and spiders for the 3hp, dunno if he has the LA style frames (assuming yours has the 4 side bolts to hold the top on that's easiest) or you'll have to buy some adapter rings and a TI frame. Will run you some money to recone those with OEM parts... Also there are some 15" TC proto plastic cones on here that look pretty sweet. Would be very unique.
