I recently entered a bass competition and hit 137.4 db in a homemade box with one mtx 81000d and one 12in pioneer spl sub running at 2 ohms. well since then i sold the amp and baught an mtx 7801. the 1000d had been repaired before and i didnt like the controls on it. I was wondering if anyone knew a subwoofer that would hit harder than the pioneer? Im only looking at running one subwoofer in my setup...Thanks for any help

Its not the sub that gives you the best SPL, its all about the intsall. But if youre looking for a single sub that can withstand a severe SPL beating, I would look into a DD audio, TC Sounds, or RE audio sub. Fi Car Audio is also another one that would suffice...

lukeyn, we need more info about your current setup. What kind of vehicle, what kind of box, how many bubes, which way is the sub facing?

DJ...I have wrote you a PM and also asked in another post to please post your competitor stats with a sanctioned organization. Care to share them yet?
I have one suggestion........Kicker..Single 06L5 or 04-05 L7 in a 2 cu ft box would do nicly on that amp

I hit 217.6 dB in my 1971 Honda N600, with a 4 inch full-range driver in the dash, with a Radio Shack 40 watt power booster! It was for .003 seconds, with a burst tone at 1.5kHz... The military heard about it and considered duplicating it as a pain generator, to attack Osama. I wouldn't share my secrets though.
Oh, sure, I had to upgrade the booster's power cable to a 2/0, it popped a 300A fuse in the process, and let the magic smoke out... and it only did it once, but the point is, it DID it...
This guy is getting on my nerves. djscustomz, you've been called out twice, now, by a respected member of this forum, and an SPL record holder, and you have yet to respond. I'd personally like to know who you are, where you compete, and what you or your team's stats are. If you aren't going to even consider backing up your claims, my suggestion is avoid making them. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.

The box is just as important, if not more, then the equipment. Throw the specs of the sub into a program like WinISD and see what you come up with.

well as far as the box is concerned, i played with winisd and it says that this airspace/port combination is the best for this subwoofer...one concern i do have is that this box is wedge shaped, will this have any effect on the woofer?
Posted By: jeffchilcott
Date Posted: September 22, 2006 at 12:56 PM
Wedge shaoe has not hurt any SPL testing for us...But I will give you one thing to try. If you can find the resonant frequency of your vehilce and tune 8-10 hz below it you will see a substantial gain in most applications, but generally this is a competition style box only!!!!!!!! they normally get tuned in the 45-50 hz range and will severly damage a woofer if used for music below the tuning frequency
If you list your vehilce I will probably know the tuning point of it or pretty close...let me know and I will see what I can dig up

I know the tib's respond to a CRX style box quite well. 2.0-2.5 cu ft with 2 (4in) aero ports with the tuning on the box at around 45-50hz This box is for 2 subs so you could go with half this for one sub.
Most of those cars I have been in have been the loudest using a frequency of 56-58hz so I would tune at about 46-50hz for whatever box you build
Remember 2 things...Not always does it sound alot louder, the human ear percives lower notes as being louder then higher notes, but higher notes are much easier to achieve with less strees on equipment.
2. Do not use these types of boxes for equipment, you will destroy woffers very very quickly, with most music it is very easy to run far below the tuning frequency and your sub may move uncontrollably if the suspension of the woffer cant handle it.
I hope some of this helps you in the right direction If you have any more questions just ask, I will check this post often

I just got the DCU105 for the eclipse avx5000 in and will be ripping back into the car, and system when I get some time away from Bp. Also any connection ideas for using a combination of a JL 450/4 AND a 300/4 for max surround possibilities?

I've never had it metered. But if I tuned it right im sure I could hit in the lower 140 range. If you're looking at a TC Sounds driver for competition, Go with one of the new LMS-5400's or TC-5200...

Posted By: jeffchilcott
Date Posted: September 25, 2006 at 2:32 PM
If I understand right are you asking if its alright for a 3in port diameter? That is fine.
Or are you asking, distance from inside of the box?
General rule is one port diameter away from any surface inside and outside the box

This is only true if the diameter of the port is 3" or smaller. The rule of thumb for distance/clearance from the end of the port is the same or greater than the diameter of the port. -------------  the12volt • Support the12volt.com

Thanks, 12volt. I stand corrected...or sit as the case may be. I will adjust my answer. For the port you are using, 3" of clearance all the way around the end of the port inside the box is what you need. ------------- The Flakman

Posted By: haemphyst

It will be the same as having too small a port, but too long... this will shift the tuning frequency, and could (just like ANY mis-tuned vented enclosure) cause damage to your woofer, if the mismatch is severe enough.
