Re: Sealed 3.5ft^3 Tumult Project

We should start a game thread. I have two PS2s, two Xbox, and three GBA SPs. I'm not much of a gamer, but I love the hardware.

The consoles are modded.

I want an Xbox 360 at some point.

I want an Xbox 360 as well...Too many speaker projects to afford it though After I blow up the Tumult, next on the list is a Tc-2000 or Tc-3000...hehehe

If you don't have a BFD for your sub, get one fast!
If you don't have REW, get it now!

Re: Sealed 3.5ft^3 Tumult Project

Meh, I don't know about the TC-2000s or 3000s now that Adire's new specs are up. The Brahma 15" d2 boasts a nice boost in Bl, lower Qts, and much lower inductance compared to last generation...Looks Very good in a box 110 liters in volume :-) Not much pricier than the Tc-2000 either which doesn't have a form of linear topology in it's motor (still a great motor though, same as the one found in the KILLER SS rl-p 15 drivers )

On a good note, I got around to setting up REW with my new X-Fi yesterday. Things look much much flatter than before. I wonder if my soundcard needs some type of calibration file?

Re: Sealed 3.5ft^3 Tumult Project

Soon to be mating with the Tumult is an Avalanche 15 currently heading my way. I'll also have a 3.4ft^3 box to put it in by early/mid september. This setup co-located should be good for about 110db @ 20hz (anechoic, no Eq) with only 450watts feeding each driver I wouldn't need much more than that.

Lol.
Hey, LLT is always an option (when I move out of my house) Still in college and living at home...My mom doesn't know I have another enclosure, and driver on the way...she only knows about the amp. When she finds out about this stuff Im sure she'll kick me out for good This is only sealed enclosures too...Imagine what an LLT would do..

Re: Sealed 3.5ft^3 Tumult Project

Amp arrived! But...it doesn't seem to be getting enough of a signal to get any decent output, even bridged... Wonder what Im doing wrong? This is my first pro-amp. I've boosted the LFE channel to +10 db and still am barely receiving enough of a signal to move the driver. Receiver is an HK AVR 235. Help me please!

Re: Sealed 3.5ft^3 Tumult Project

What amp is it? Try running just a single channel with the amp gain all the way up. And I assume you're using an RCA to 1/4" adapter?

Re: Sealed 3.5ft^3 Tumult Project

The amp is a Behringer Ep 1500.
Had it hooked up the center channel pre-out instead of the LFE pre-out, DUH. This sub is rediculously badass. Can't wait to get some measurements for you guys. They'll be comming soon. I've never heard this much bass in my life...WOTW clips the amp, well before the Tumult even reaches max excursion... Music sounds tight and crisp with less "dryness" than the Rythmik, and obviously lots more output due to a larger Vd and more ampage... Very impressive sub.

Final design ended up being 3.9ft^3, with some internal stuffing. Thanks to a low Q allignment the transient response is incredible.

Edit: No smoothing, no EQ measured from listening position far from max SPL.
