Posted October 29, 201014 yr I would like somebody to explain to me how Mark gets 143dbs with 1 12" XCON on a khaotik enclosure and the guy from the tahoe only reaches ~156dbs with 4 18s?I mean, I know after certain point, each db requires more than just another amplifier or an extra battery, but I cant understand why the difference is so close. Either the XCON is THAT good or there is something going on with the smd subsIs it that the 18s are in a box that is not spacious enough? or is it that the box needs a redesign? I believe I remember st3ve saying each of the smd subs had 4.65 cubic feet, I think that sounds kinda tight.
October 29, 201014 yr Installation trial and error !!! If you build it wrong, tear it out, get after it ...If you build it right, tear it out and try to make it better ... The more installation experience, well there you go ...We have a vehicle in our camp that holds a world record of 180.9 in its class. 2 12s and 2 Linear Power 4.1s ... A pair of 10s at world finals street beat class did an obscene number this year ... anything is possible bro ...
October 29, 201014 yr Admin There is not a linear increase based on cone size and power. Just too many factors that play into it.
October 29, 201014 yr There is not a linear increase based on cone size and power. Just too many factors that play into it.x2!!! its vehicle and install dependant. also frequency, there are just too many factors to play into this. and yea, 156 is like crazyness loud compared to a 143.... lol

Alot of factors here.Alexis' Caddy made her run a 77 htz.
October 29, 201014 yr Author Now I understandBut that leads me to ask, so why did he bother with 4 18s when he could have used all that space for maybe 2 12s, a nicely designed box and much more amp power?Was it a personal choice or did it have to do with SQ over SPL?
October 29, 201014 yr Now I understandBut that leads me to ask, so why did he bother with 4 18s when he could have used all that space for maybe 2 12s, a nicely designed box and much more amp power?Owwner prefference i guess ... some people drice fords, some chevys, some dodge. Who knows, what ever works for them, especially in competition where the vehicles are set up to meet the competition class rules.Was it a personal choice or did it have to do with SQ over SPL?2 difference objects here ... nuff said for me ...
October 29, 201014 yr hahaha slim142 every 3db's you increase it's twice as loud so a 143 is a joke compared to a 156!!!!!!143-146-149-152-155!!! 5x louder thats a hell alot louder!

If I lived near the beach, I probably wouldn't have a SQ vehicle, well yes i would.

Start going to shows and what not, thats a way to hear real bass (over 150dbs) compared to novice bass most of us on here have .
October 29, 201014 yr Author I mean, the "best" I have seen is my friend who had 2 15"s Kickers (Yep, you guessed it right) L7s, he had a really nice setup BUT his amp was one of those random-ass brand ones and he wasnt getting the best out of those subs. He hit hard, but I wasnt surprised. When I realized about the amp then I knew why.Then one time I was in Tampa and I saw this blue impala that seemed to have 2 15"s. That shit was LOUD, I heard it blocks away clear and loud, when it passed by where I was, I was impressed by the bass coming out of that car. Kinda wished he could have given me a demo lolSo yeah, I do not know what 150dbs feel like, or even 140dbs. But trust me, IM DYING TO HEAR A SYSTEM THAT LOUD! (thanks to this forum and the people here hahahahha)About the shows, there are some, but sucks I have to drive pretty much 2 hours north. Im between south beach and broward and trust me, I have not seen or heard about any shows here in the Miami-Dade area. Everything is up there (Palm beach, west palm, tampa, orlando) and thats a 2 hour drive for me (4 to orlando).
October 29, 201014 yr get on FloridaSPL.com and you will see that there are shows in your are, there was a show in Homestead last weekend I believe.

October 29, 201014 yr i go down to south florida every spring break. If u wanna hear what high 50s sound like, you can if u want me to stop by your place on the way down....It won't be til around middle of March of next year. PM me if u want so u don't lose me.
October 29, 201014 yr and that guy with the Tahoe he could be a lot louder... but doesn't have sufficient port are
October 29, 201014 yr and that guy with the Tahoe he could be a lot louder... but doesn't have sufficient port are which one? Theres two hoes?
October 29, 201014 yr hahaha slim142 every 3db's you increase it's twice as loud so a 143 is a joke compared to a 156!!!!!!143-146-149-152-155!!! 5x louder thats a hell alot louder!You suck at math. That's actually 2^4 x louder which would be 16X not 5X
October 29, 201014 yr At 143, your eyes might vibrate a little, you can feel your ear drums flexing, it's not all too intense though. At 155, your eyes get blurry bad, it starts to get hard to breathe, and your head feels like someone is sitting on it. The feel varies at different frequencies, I'm just saying I've sat in both on music and that's what I experienced. 143 to 155 may be a small number increase, but a big SPL increase.
October 29, 201014 yr Let's not forget Alan Dante's 1 18" puling 180+There is a huge difference in installation, because those "guys" with the Tahoe's have more power and cone area than Dante, yet he's more loud, how do you think that happens?It's obvious they don't know what their doing
October 30, 201014 yr hahaha slim142 every 3db's you increase it's twice as loud so a 143 is a joke compared to a 156!!!!!!143-146-149-152-155!!! 5x louder thats a hell alot louder!Your math is incorrect sir. For every 3 db gain the sound is twice as loud. So 146 is 2x louder then 143, and 149 is 2x louder then 146, making 149 4x louder then 143. And thus a 155 is 16 times louder then a 143...... The sound difference is more then most can comprehend without have listening to both for extended periods, I have owned a truck that did a 143 on music, and I now own a van that does a 150 on music, and even that gap is simple astounding.hahaha slim142 every 3db's you increase it's twice as loud so a 143 is a joke compared to a 156!!!!!!143-146-149-152-155!!! 5x louder thats a hell alot louder!You suck at math. That's actually 2^4 x louder which would be 16X not 5XDidn't see this till after I posted. lol
