I completed a second AT for my truck build today. Put it in my truck and it’s pretty loud!!!! I am excited to finish up the third cab. Bass totally drowns out my mids and highs but the low frequency extension is amazing it plays as low as any 18” driver setup I ever had in this truck. I have achieved a loudness or intensity level that causes a lot of noise from the vehicle which takes away from the hifi attempts. I have three layers of dampener in the roof and a layer in the doors of the truck but Thats not helping the panels and such..

The plexi doors are rigid as I would hope for so super happy about that. Not sure why but being able to see the driver move in relation to the sound I hear makes it easier for me to feel good about a peak output gain setting. The guess seeing the driver flop like crazy helps ensure I’m getting the most out the driver!!!

Position in the truck matters I put just one cab in a few places and I have had the horn unload and sound like garbage I have also placed it in other places and got a lot of gain and low end extension this is not new to me exactly but for the sake of saying it, I observed in certain positions a severe amount of unload at first it was alarming but I moved the cab and the spl cape back. Scared me for a second....

Tonight I hope to have the third cab completed.
I will again say that the modified build method I used works but not really any huge benefit over all, required more glue, three times the cuts and three times the room for error. In the future I will stick to the plans....

I finished up the third AT today. Put it in my truck. So three 19”wide ATs with Dayton dcs-255 drivers. The amp is a kicker 750.1. This setup is almost as loud as when I had a ddaudio 9518 18” sub with an 8cuft box on a 2kw amp. I had dual alternators and could pop a 140amp fuse to the amp. That setup cost me easily $3000 for everything in the subwoofer setup.

This current setup is like 400watt totals consumption, it still out runs the mids and highs and cost me less then $400 for the drivers and material for the horns. I am running off stock electrical and can play it hard with the engine off which I could not do when I was running the monster 18” subwoofer.

No joke guys three 10” drivers on a 750watt amp only pushing 400w is slamming my truck. The bass is the cleanest I have ever had. In order to make this bass systems work I have it low passed at 50hz so that it can somewhat blend with the mid range drivers and then when I put in a bass heavy track that digs down low I can destroy.

This setup is not hifi, not at all. Because of the bass bias any rock/metal sounds muddy. I can tune it to be correct mind you but the goal was highest spl in the 50hz and below region.

these tracks through the system get stupid real quick I love it!!!

Man, that is so awesome! Congrats on the completion and success :thumbsup: You might even try high passing it at 40, see if a 24dB is too much. Would be great to have 2 high passes, one to tame the rising response of the horn and the other to transition into the mids. But, I'm not aware of any hardware that offers the option.

Too cool. Congrats again

I tinkered a little with the setting today I can low pass at 80hz 24dbslope, and dial it back and get a good crisp tight bass out of it. It’s nice!!! I can do what I said earlier and lowpass at 50hz 12dbsloped and do some has heavy bass track playback and slam the truck. Just what I think will make me fit into that car audio scene I talked about in the beginning. With a little luck I may build and sell some subwoofers to these guys in the future!

I can double low pass first off the active head unit filter and again on the amp itself but I am slow to do that for some reason. I eq-ed the system up a bit still pending hitting it with REW, as I have 5 peq function on my headunit. I got it sounding pretty good but at peak bass output the highs/mids are mush as above stated and expected. Still happy about the performance of this stuff, the guys I know have a term lab mic and I will hopefully measure the peak spl and clamp the electrical to see what is actually happening! No one likes being out done at their own game but I am hopping to shock these guys with my odd low power setup!!!

You'll certainly ruffle a few feathers with a low dollar, low power setup because most people think you need to spend loads of cash to be the top dog which is even funnier when you're aiming for single frequency farts of bass for a few seconds at best.

There was a meet last night, Tucson Arizona. There were around 30 vehicles that showed up a few more than last time I went.

Some of the rigs were:
4) 15” Orion hcca drivers, bass reflexed
2) custom 21” drivers, bass reflex/walled
12) 12” planet audio budget drivers in 4th order enclosures
8 ) 12” audio pipe txxbdc4 drivers, bass reflexed
2) 18” drivers walked in a sedan bass reflexed
Several vehicles with dual 15” drivers in complex 6 order and some cool 4th order enclosures.
There were trucks with blow threw setups where the subs are in the bed and tunneled into the cabin!!! There is some serious high dollar rigs in this scene. Most of the people showing up here are metering a peak in the below 80hz area over 150db on a termlab or comparable measuring mic.

I got to sit in a few vehicles and demo. It was a ton of fun. Some sounded half ok and would play pretty low in the frequency range, I just love 20-26hz with some authority. Other vehicles sounded awful with panels and parts rattling so hard and bad all I heard was a fart sound at 150db!!! I laugh on the inside at those situations as it is so funny to me how proud of it these people are I just see it as ridiculous.

The bottom line it is all one great big dick measuring contest, the epitome of peacocking. It’s a display of money and power. And these guys walk around checking everyone’s stuff out comparing sound systems and vehicles it’s silly when you scroll out and look at it.

I showed up with low power and very little money invested and I sounded better, little to no distortion, nice and deep bass, and I was excepted as yep your truck is sounding pretty good. A few guys praised me on the efficiency of my setup. There was a chick there who demoed my sound and she said that my system to here was the best she could listen all day not fatiguing at all smooth tight she liked it. Every other cock in the place would say that’s cute but check out mine, I would go over to their vehicle where there would be easy $10,000 invested in cables batteries amps no back seat a million subs facing me looking more like cannons with lit fuses and sometimes as little as a $50 set of coaxial mids then they hit play. My breath gets taken away I get all itchy vision blurs, and all I hear is vibrating door roof panels and it sounds like the midrange speakers may be half blown. The guy at the controls smiling ear to ear looking like look my wiener is bigger than yours naaaa naa naa naaaaaa nah! I’m like that’s cool man I’m happy for your big dick. I really enjoy audio systems and the cool setups there are, really I was like a kid in a candy store all night last night checking out and chatting with these fellow audio people. Some of the designs were really freaking cool to me.

I used to be so fascinated by Loud low frequency sounds that created a vortex of moving air around me to the beat of music. Years ago it was my life. Once upon a time a 40hz tone could Stimulate my senses and make me happy. Today I need a little more to get my rocks off. I need a talented musician to move me today and I need a sound system to highly accurately replicate with some authority the music the artist created. I find it petty the peacocking and bad sound quality that is desired in that scene. Honestly I hope two sell off two of the subs I built and just end up with the one as it is plenty. I was pushing all 700 available watts to those Dayton 10” subs last night and they took it. Need to put a dmm on and see just what power I am actually using but I pushed the rig till I got voltage drop which tells me I was maxing out the amp.

All in all the build was fun, sounded great and I don’t know how I could have made the system any louder on a tight budget using the existing 700 watt amp I had while still maintaining some level of sound quality. Car audio draws a certain crowd and certain interests who am I to criticize their passion and art. I got my fix now back to making money with my pro sound dj endeavor.

I bet it gets more usage. :hyper:
Guys do this kind of stuff in hopes that it will make them more attractive to women. By and large not only are women not interested in the silly things boys do, they think it's stupid. Want to get laid a lot? Don't waste your time doing dB competitions. Learn how to cook. Give a girl a reason to want to stay over for breakfast the next morning. That starts with making her a killer dinner that night.

It's great to hear that yours was so good-sounding! :clap: Hopefully, others will catch on.
