As promised.

My review of the Unhorn Subwoofer.


First off, i knew this thing wasnt designed for rap, i took that into careful consideration before running it through its paces. I know quite a few rap tracks that are starting to get into the mid 20's for the bass ranges now. its pretty impressive, but hell on any sort of speaker, subs or not. It takes a pretty beefy setup to keep up with todays rap at any kind of SPL considered LOUD in my opinions.

The box was absolutely tiny! i couldnt beleive how much sound came out of such a tiny box! 114 db peaks in the car as we were listening to some techo/pop. The sub, like mark said, is no good under 35, you get overexcursion and a lack of sound. nothing that a high pass wouldnt fix. the 35 hz range is clean, undistorted, and come out with some serious authority in the car. As you crank the test tones closer to the 50-60hz range, the sub really starts to hit its element.

The bass is pretty much as flat as i have heard it. Sittin in car me and the other guys were lookin at the SPL meter playing test tones in increments from 40hz to 100hz, the dB meter never swayed more than 2 dB up or down from our baseline. The car did have a hell of a resonance around the 75-80hz range, the car was rattling a bit, but thats got nothing to do with the sub, but the cabin size/resonances of the Toyota Matrix.

All in all, its an absolutely awesome subwoofer for rock/techno/pop/classic. But it really doesn't hold its own under that 35hz range. Bang for the buck? its louder than anyone should ever need in a car, and so small that you could hide it under your seat for the most part, or stuff it in the corner of the trunk with some velcro and no one would even know it was there, 'till you turned it up.

I'm excited for the 4x SDX 7 setup. flat to 16

Nice review, Binary110!

I can't wait for the Trio8 design

"I'm excited for the 4x SDX 7 setup. flat to 16" huh?

[mwmkravchenko]

Ok if the people who want flat to 16hz want to look at the first posts the sub design is there.

Is it going to live?

SOON VERY SOON.

Flat to 16hz where?

In a car. Flat as in takes into account the cabin gain and is naturally EQ'd to behave itself. Remember me hates over blown bass. I like alot of bass where and when it is there in the music. One note bass need not apply in my car. But I do miss being able to hear a mean 16hz low C on pipe organ CD's with the proper rattle and roll. So yes I'm building it should be ready early next week.

It's the true heavy metal gents!

P.S.

The twin trio 8 horn is going from theoretical to design phase. Some where sometime. But seriously the little box kicks serious butt someone should build this and give it a try. Or buy a precut and try it yourself.

[mwmkravchenko]

Do you want to see a horn with 4 SDX7 as per beginning of thread more or less flat to 16hz.

OR

a dual trio 8 that is good to 30hz.

Both are not to small. Both are in and around 3 + cubic feet. I will post only one that gets the most votes. Both will fit into a space of about 38" x 26"

Both will be equally as loud more or less. Actually the SDX7 horn will be more efficient and capable of going louder.

So vote!

Remember this is a thread by a benevolent Dick Tator also known as Richard Potato Head. I should go to bed right about now me thinks.

Vote

MMM

[brsanko]

MMM, They're both about the same size but one is louder, lower, and more efficient? What is the deleima?

[zora]

I vote for the 4 SDX7 version.

I vote for the Trio version because the cost of four SDX7 woofers is outrageous. I think you will have a better chance at getting people to build your design if the driver costs are kept lower. You need to keep things real here. While four SDX7 woofers looks and might sound cool, I doubt you will get many people dropping over $400 in woofers just to try it out.
