box design for 12" mach 5 ixl

[hamiltonaudio 10+ year member]

in this case I'm inclined to agree for the most part - but there are a small handful of other issues that are affecting performance as well.

No reason the box should be too small. In fact, that is what was recommended by Mach 5 Audio for the 12" IXL driver. I re-checked everything on two different box calc's and it is 1.89 cubic feet tuned 32.6 Hz. Once the woofer is installed, net volume should be right at 1.8 cubes at 33 Hz.

Personally, if not recommended otherwise by Mach5, I would've gone for 2 cubes at like 35Hz, but I would assume Mach 5 knows what they're talking about /sigh

EDIT: Good thing is, you're canadian, I bet wood is dirt cheap by you eh? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

hahahahah yeah I guess wood isn't so bad around here //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Ironically the owner and mastermind behind Mach 5 lives right down the street from my shop - so I have the inside track //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Our box designs come from flat out test-mule-box testing. For the audiophile type anything 1.8 to 2.0 cubes net at 33ish would be perfect. Nice speed, great extension. However, our testing and TermLab results tell us that a little larger and tuned a little higher is far more effective (and desireable) for our younger customers. They like the improved output (in many cases vastly improved) and upper end punch, right where the majority of their rap, hip hop and top 40 music plays the most.

If I told you what we were doing with 12 x Mach5 SPL12's you'd swear up and down that it'll never work - let alone make any pressure. The TermLab will prove different //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif And funniest of all is that Mach 5's owner is as excited for us to do it as anyone. Mark and Sean - shhhhhhh ......

I fail to see how it's tuned too low as well...I have my IXL 10's tuned to 28hz, and love them. I guess some people just prefer peaky bass in the 40-50hz area.

its tuned to low for his intentions. im pretty sure our man kyle here isnt looking for the kansas flat response, but something more along the lines of a peak of around 40-42 for loud bass reproduction of hip hop and rap songs. add a decent front end, but not amplified we also now need to have a sligtly wider response as well to fill the gap in the front end.

once our local dB drag is over, and i removed my SPL 12, i intend to run a pair of IXL 12s in a mid to low 30s box. but ill have a HIGH powerd front end with two pairs of Macrom M2s to get down into the mid 60s, ill let the IXLs take it from down there. and this will be a a demo vehical for our shop!

not everyone has the same musical tastes as you //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif The sub SOUNDS excellent - no doubt - I do believe his "disappointment" is with sheer output. Lower tuning, smaller volume and shitty power all hurt that don't they?

Unless Kyle himself says otherwise, thats what I'm goin with //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

The power is defenatly the prob. And its gonna take a couple boxes to acheive what I'm looking for u don't get a perfect box the first time around

You positioned the sub in the wrong spot //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Keep the sub as far away from the port opening as you can.

Whatcha talkin about, that box was god's gift to you. Get your ears cleaned //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Yeah, a little more power and actually breaking the sub in would REALLY help. Even on my shitty comps, I noticed a difference when they were broken in. Even with how squishy the surround and spider is, once they were broken in, they got louder and lower off the same power. If you have a chance, just play a really low note, like 25 Hz, something below the tuning frequency so the subs can pretty much free air. Just let them play for awhile, keep an eye on them, don't jam on them or nothing, just kind of break them in a bit with some light excursion. That's what I did with mine to speed up the break in process.

perhaps it was a gift from god, but perhaps it wasnt for him. this young lad is looking for the most out put, but still musical and usable for a daily set up. the genaric IXL box is spec out to suite most SQ tastes, aimed for Home audio and for those of use with good front ends. also for those who love the low end, wich is about 15% of you average car audio customers. the other 85%, usaly from the ages 16 to 24 want to wang hard. to impress there buds and to be heard then scean on cruise night. i beleave kyle will fall into this demographic. hes a young enthusiast, who not afraid to pic up a saw and a bottle of glue and play. but being a newb to the hobby he needs some advice based on his application. perhaps if you asked him, what kinda music do ya listen to, most of his curent box issues would have been resolved.

kyle, due to your lack of power, i sugest a bigger box, a tad bigger then 2 cu ft net, and for tuning 38-40hz. also kyle perhaps look into a pair of 3" ABS vents. something that can be removed and shortend up or swaped out for longer ones to play with the tuning. youll find the sweet spot dude. in most cases, theres noting better then real world testing, via a ear, or if your lucky a term lab. good luck with the build!

yeah jay i def want loud forsure. and it does take a bit of playing around with. ill probly be doing a box this week or weekend if i get a chance. as for power im stuck with that POS for a month or so unfortunatly //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
