Printer Friendly Forum Posts - system that will hit 145+

I live out in hawaii and i am tryin to build a moderate system thatll hit 145+ i got 2 mtx 9510's and i have hit 139.8 on the term lab already should i go for different speakers or buid another box and just use what i got.........i think that these subs have potetial....its in a newer model frontier.. i am runnin 2 yellow top optimas and a big cap....for amp i have 1 mtx81001 and its wired to 1ohm.... the box i have them in is mtxs sledge hammer enclosure....does anyone have experience with these... can a 145+ system be done with what i have?should i just sell these and go with something different like strokers or ma hardcores or something else please help.....

i just got in touch with american bass and they can get me a 15 inch vfl dual 2 shipped to hawaii for $350 should i get this and just run that?????would that be better? what about ma amps are those good? their is a store online that sells them kinda cheap a 4400rms at 1 ohm for $399 or should i just buy anther 81001 and strap it then run the vfl?or build a bigger box for the mtx speakers....

I would get another 81001, put one on each 9500 10", and build a better box. With 2 10's, you have more space to work with for something emaculate. I think the 2 10's have more potential than that AmericanBass 15".

$.02 from me.

should i make a ported or sealed box?

I agree with Jmelton I would stay away from american bass. Those speakers are definitely worth keeping and in a different enclosure with some more power and you should be able to realize your 145.

Ported is the only way to get huge numbers. Find out what ported box volume MTX recommends for each 9510, find out what tuning freq. you are to be competing at, figure out the port diameter you prefer, and use this calculator to find out how long the port needs to be.

Also, more power! posted_image

i did go to mtx .com and the sledge hammer enclosure is already at the spec theyt 139.8..... i am part of a small team that is starting out... im not the box guy im the wires and alternator instaler guy posted_image

......but the box guy said i might get a few more db from a different box...ohh and the 139.8 was with music....but our senior guy said that american bass is good he was runnin kove speakers..2 15's and hit 155 on the term....but he suggested going with those thats why i ask....plus down here every one is in the dd phase so i would be competing against those all 9500 though no 9900...so should i still just build a different boxeven though i already have the box that mtx recomends...and the amp they recomend for 2 9510's...another 81001? should i will it be okay...

Have to tried positioning the Sledgehammer any different ways?

I'm sure a different box, built Really solid, would have better results.

they only fit one way and that is with the speaker and the port facing up other than that they be facing chair .......what kind of box do you recomend doubled 3/4 inch mdf with reseign on the inside cuz my freind was going to build it like that and have the ports come out facing foward rite in the middle by the armrest...that good enoupgh and the speakers were going to be stil facing foward...

https://www.forumshawaii.net/vbb/showthread.php?t=326803&page=3 here is a link with pictures of how its setup rite now its toward the bottom of that page....

I would try 4x Mtx 7500 12's with the TA81001 you have.

why i got 9500's already why would i step down like that and if you lookedat the pictures i posted where am i pose to put 4 12's and still see out the back....i got double 5% tint hard to see at night.....i think ill just get another 81001 and another battery and a bigger box.......cuz no one makes alternators for my truck yet...so gotta jus run plany batteries....

because you said it.

A lot of people don't know the 7500's, believe me, if you can fit the 7500's in there they will absolutely destroy the 9510's with the same Amplifier power.

I have both, but currently i have the 4x 7500 (Sealed enclosure) in my car, you can see it here
and they are very loud for sealed enclosure.

I've tested 2x 7512-04 against 2x 9510-44 with the same TA81001 and the 7500's where louder with less power.

thats a nice setup i have the same amp for my mids and highs also....... what kind of numbers do you hit with those..... i know that 7500 are good but do they travel like 9500..... i just assumed that the higher number would be better.....i mean in my truck sounds like doodie but open all doors up and you can hear that puppy far far away.... and you can feel it a good distance from the truck also.... so your runnin all four with the one amp? are svc or dvc ..... cuz their are some people down here that may be willing to trade like 2 for 1 or sumthin......

and also i wouldnt wanna move outa my class so if i were to go bigger i would only go 1 bigger.....like 1 15 or sumthin but that will be louder...cuz 4 12's will move me way up to uncharted teritory and i know if you got 4 12's and you aint in the mid 150's then no use even try....

A guy over on ROE hit over 150db on the term lab with one 12 inch 9500...it is all in the enlcosure.

If you want you can contact https://www.mobileaudioconcepts.com/ and they can for sure get you to 145db

And did that surprise you? you have more cone area with the 7500 12's = 226.2 and for the 9500 10's 157.1.!! would be a closer (more fair comparison) with 3 9500 10's to equal cone area.

Yeah i know that it has more cone area, but i was talking about power, 3 9510's against 2 7512's are close in cone area, but what about power? more Amp power, bigger Alt?? for the 9510's to achieve almost the same result as the 7512's? (if both boxes are build right)

going for all out SPL? Look at the Kicker l5's or l7's There is a reason why we are winning so many shows!

I dont know what type of truck you have, but using 2 12in L5's and 2 kicker KX1200.1 we were able to get 152db last year at a show with a 2 hour install. Not setup for music, but still loud

Are you running a setup where you are doing a peak? or music based when you record your scores?

the 139.8 was with music busta rhymes touch it song and id like to hit 145+ every day with only 2 10's or a single 15 i really dont care for kicker for my own use to much people over here have them and dd their in that phase now but they are slowly moving to fi and re thats why iwanna either stick with mtx or somthing different like mmats or stroker or american bass or ma audio....you know a little diferent from the norm over here....plus i dont really wanna spend more than $500 ...for another sub.... as it is rite now im only 0 .7 b away from my team mates dd9515and his is in a blazer......so yeah i like kicker but not for personal use...and if i was going kicker it would be solox not no l7....

you need one box with one large port. if you want max spl for your truck, you need to build a box for that truck specifically. the box makes the BIGGEST difference in the way a woofer performs.

"If you ask questions, you're a fool for 5 minutes; if you don't, you're a fool for a lifetime."

to get the highest spl at the dash, measure the distance between the top of the dash where you usually put the meter mic back to the place where the box is going to be at. take that measurement and mutiply it by four then that is the wavelength you need for max spl. take that wavelength and determine what frequency has that same wavelength and build a box that is tuned to max output at that frequency and play only that frequency (or one of it's octaves) at competitions. that will give you the highest spl reading possible in that truck. also dynamat or similar, and brace everything you can. any vibration that occurs causes loss (i.e. glass vibration, dash rattling, doors flexing, etc.).

DO NOT CHANGE ANYTHING BUT THE BOX...the amp and woofers you have are fine. you are not getting the max from them yet. trust me, i have helped acrue over 100 trophies in spl competitions at the shop i just left 3 days ago.

when i get around to it i'll pull out my work laptop at calculate the wavelength and frequency at that measurement and even tell you the port size and box size you need to obtain that.

100 is a hyperbole...realistically it's about 40 or so with my now hated ex-boss Larry Todoroff with Team Kove. 24 12's in an astro van with 16000 watts. some local shows helped accumulate that number.

okay.... just let me know what 2 do i got a picture of the way its setup on here just take a look.....and the flex is vey minimmal in my truck vibration 2....plus il be getting started on a new box in the next week or 2...

What type of truck are you using? I have a few designs laying around that were all good for over a 150, but at a much higher frequency (Not streetable) If you would be interested in something like that I can try to help, but need to know what type of truck it is first

Newer model Nissan Frontier I belive he said. I know it looks like an extended cab pickup in his picture.

yeah its the newer model frontier extra cab..... not the crew cab.....

you need to measure from your dash to where the box is gonna be
