For reference, cross an AV123 fanboy with an Emo fanboy and you still don’t come close to the fanboyism of some of those DIYers. I mean you think the cognitive dissonance in a speaker purchase is bad now you’re talking about people who are making their own, and they are better at it than any of the “pro” manufactures out there in their not so humble opinions.

Some of the DIYers are really annoying, however I don't follow the DIY crowd all that much. Oh well. Nothing beats a good ol` 123 fanboy/apologist atleast in my experiences. The 123 fanboy is verging on extinction, so the DIYers or EMO can proudly take their crown.

Right, Dean; two widely separated(for room mode cancellation/minimization)subs provide a 3dB increase. Two very closely situated(within about 1/4 wavelength)subs for simply increased output level because of increased mutual support can provide about a 6dB increase.

Thanks for confirming that John. I was pretty sure I’d read about the 3dB part but must have forgotten about the 6dB if place together. Good to know that, not that more subs are very high on my priority list right now.

More subs shouldn't be high on my list, either, but if I can get by without having to ship so many subs back, all the better.

I'm kind of glad somebody brought up the DIY subwoofer community.

The tools, measurements and theory behind subwoofers have not only advanced, but also become readily available over the last 10-15 years. While on most days I am still smart enough to grasp my own limitations, I don't think it is ridiculous to assert that DIY'ers can construct subwoofers of professional quality. Available computer models are remarkably accurate, and - most importantly - the designer is only dealing with one driver and a very narrow, predictable, imprecise frequency response.

Subwoofers don't have to deal with baffle correction, crossovers, or - to a great extent - distortion.

I think this is a good reason why value-added technologies like Axiom's DSP are significant.

My contention is that subwoofer design is almost pure science (leading to commoditization and narrow margins), whereas loudspeaker design still requires quite a bit more art.

Can you even hear 13 Hz or does it simply induce vomiting and confusion?


Don’t know. They warn against it at work but even doing extended power runs on the engines 4+ hours has never caused me any problems while running ground. The ground shakes which is exactly what the Buttkicker feels like, but I have no way of know what frequencies it’s getting other than below 40Hz where the filter is set.


This thread has been on topic for a long time. Tagging on to Dean's comments, I went to the NHRA "4 Wide" top fuel drag races last Saturday in Charlotte. I had never been to a drag race before - and of course, they start with the lesser horsepower stuff first. I was not prepared for the Top Fuel boys & women when they came out. Each "car" "rocket" puts out 8,000 hp. At 4 wide the effect was nothing short of incredible. I am sure that there was some "stuff" in the 13 hz and below range here. To further heighten the effect, we stood at the start line - you could actually get quite close - when the light went green, the result was nothing short of indescribable. I am sure that either my eyeballs or my optic nerve vibrated as the entire scene sort of pixelated. I did not puke, BTW but I did utter a few expletives.

8000 HP?! I had no idea they were that crazy.

I thought it might be fun to watch on TV, but drag racing is intensely boring if you're not there.
