Two Danley designed B-Deaps (4 - 12" in a horn designed to play 35hz and up http://www.soundphysics.com/SPL-BDEAP32.html)
Two Ricci designed Othorns (2 - 21"s in a 35hz and up world beater designed horn )

All powered by SpeakerPower amps, in a room that is 13' wide by x' long. Alex can perhaps provide the length, which I think is still under consideration as he may shorten his space. I have to think that at 15z this system is going to be top 5? or top 10, and at 35hz and up it's going to be nearly unrivaled on these boards ---- assuming it all comes together.

He needs it, dude literally eats bass for breakfast. We were tapping out when he was in town and he was just getting warmed up!

Wow... a hard hat and cup will be required for demo night with such a system!

You should re-check the numbers for the othorn at 25hz...

Even before I upgraded the drivers in mine, they still had more output at 25hz than the Ghorns in my room...

I hope this is concrete construction, with a well built ceiling support system, with no additional house weight above (like another story). That is not only damaging amounts of bass, it is devastating Awesome.

Very nice! Great components. Here is a pic of your ULF Card.



Have a pic of the setup?

Been busy with Holiday stuff, but updates soon to come.

Wow...this will definitely be one of the top, could be the top dog at the 12.5hz range. Aren't the Terraforms tuned to 11hz?

Anyone have a sim of the Terraform? I can estimate if I have one.

Even though I don't calculate frequencies that high, I have to think he'd be the top dog 35hz and up; dual othorns and the danleys? Crazy...

Thanks

There is a pic over in Aiming for 110dB @ 5Hz and some sweeps showing reasonably flat extension down to 5Hz in Aiming for 110dB @ 5Hz (stopped at 100-105dB, door frame was complaining)

pics of the room itself (albeit with my old sub)

As the point of a wide range system is a flat, or often tilted up response on the bottom, tons of excess output at 35Hz and up is useful, how?

Showing off at demos. Movies and music have plenty >35hz.

Still pretty cool, imo.

Drum kicks that hit so hard they blur your vision and can make you feel sick.

95% of recorded music

As well as "cave your skull in" spl level demos of older movies with lots of 40hz content like this:
http://m.imdb.com/title/tt0171363/



Do you go to the crotch rocket forums and ask why someone has increased their top speed from factory 190mph to 210mph with aftermarket parts?

You know the answer before you even ask!

I'm pretty sure his point was something like this:
Increasing output at 35Hz, for most of us, is not analogous to increasing the top speed on a superbike. It's more like swapping in a much higher flow fuel pump on that superbike. Sure, you've got more headroom in that one specific spot. But that one specific spot wasn't your weakest spot anyway. The change did not increase your top speed. Or back to what we're really talking about, the change did not increase your top volume knob position. Because most of us are over-served at 35Hz anyway.
It's pretty hard to argue one way or another without having a lot more specifics of the installation. Maybe that particular installation has something unusual going on, and 35Hz IS the area that needed more help. It just isn't normally.

It's at 35hz and up not just in that region of bass, meaning that the usable bass for almost all music will have crazy amounts of headroom. The kick in your chest feeling will be there in spades.

You are making it sound like he will just have a boost right at 35hz.

Perhaps I sacrificed a little too much clarity for the sake of brevity. Find/Replace 35Hz with 35-120Hz.

Hey Dom.. It's been awhile since I visited this thread. Anyway just wanted to update my system. So I notice there's data fo JTR 215's. I've added 2 215RT and 1 215RM to my existing system. And I forgot to mentioned back then that I'm on a second level suspended floor. I don't know if that makes any difference. Anyway FWIW this is my last REW run with the 3 215's and the 4 S2's. Will be adding more subs soon. Mainly horn subs..
