Mach 5 12"s ported test

[bigbassman 0]

pair of Mach 5 12's in 4.5 cuft, tuned to 33hz... in my car, 05 aveo hatchback. TL sensor was placed on the headrest, vehicle sealed up..

we then tried the 2 loudest frequencies and turned the amp up until they stopped getting louder

@ 35hz, the Mach 5's did a 138.2 with 1843 watts

@ 40hz, the Mach 5's did a 137.3 with 1050 watts

video of them @ 40hz

very loud woofers for the price...

one thing I do need to mention... the coils on these drivers dcr pretty low... 2.3 ohm per coil... I'd call it a nominal dual 2 ohm driver myself..

at the very least a nominal dual 3 ohm driver..

actual impedence during testing was quite low... barely over 1 ohm actual load. For 2 dual 4 ohm nominal drivers in parallel, I'd expect to see an actual impedence out of the impedence spike area of low to mid 2 ohms..

so pick your amplifiers accordingly..

we'll be doing alot more testing end of sept, for the official test session..

Wow, I am stunned that they held 1800 watts!

I am just wondering how 1 of these will sound in a 3 cubic foot box in a firebrd. And will it handle 600wrms. What kinda of numbers do you think is possible?

you and me both...

they didn't like it though.... I wouldn't suggest doing it more than a couple times...

a 600 watt RMS amp playing music should be fine on 1 of them...

I haven't completed enough testing on the box sizes... but judging from its output in 2.25 cuft.. I think it would be fine..

may even help the sq out some...

Somebody do a dual MAW 10" ported test. I dont know which ones to order, the 12" or the 10" or wait on the 15".

I am "supposed" to be having a box built for 2 ported 10's, and I already have a sealed box for 2 15's.

I was wanting either the 10" or the 15" only because I have boxes for them in my garage already.

I have 2 ported boxes for tens but they are tuned differently so I would likely need to wait on the other box to be built.

Or like I said, wait on the 15", I hate waiting

Great review, I too am amazed at the power you put to them.

Were you planning on giving them that much when you got the 12's or did it just turn out that way?

I always continue frequency response testing until I sense the approach of thermal, or mechanical distress..

the 800 watt frequency sweep was all the power I'd want to put on them for that..

and its pretty typical for drivers to withstand 2-4 times their RMS spec, for a short burp...

so 900w a driver is pretty good from em for a burp.. I wasn't expecting quite that much though...

I've had good results in a 2.6 cube box tuned to 25Hz. Note however that you will be sacrificing power due to the MAW-12's limited excursion. You run out of excursion at about 225 watts. For SQ, a pair would be more than sufficient tho.

Best,

Mark
