TUMULT Seat

ChocoHolic · 31st March 2004, 06:55 PM

Hi TUMULT friends!

..seams to be a great driver...
The sub of Honda95 seemed somehow similar to my plans.
Sealed box 5.5 ft^3 with one TUMULT.... stated that Xmax is reached at 16.5Hz with little more than 1kW. From theory I would calculate 1.1kW, so this matches quite fine!!!

I am thinking about a TUMULT seat.
May be even with arm rests and foot rest...
...decadence strikes back... and puberal feelings coming up

Just for relaxing, listening to music and DVD-sessions.... :-)
The seat would have 2 TUMULTS in an sealed box about 10...11 ft^3 and a linkwitz transform in order to get a linear (3db) frequency response down to 12Hz. All this looks very promising.
DIY switch mode amp.
... still in the earliest stage of a silly idea, no detailed schematics and drawings up to now, sorry.

I still did not finally decide about the drivers and I am still
collecting information....

So please feel free to flood this thread ( or my e-mail) with pictures,
results and hints!

Cheers
Markus

I think it would be wise to have a bowel movement before any listening sessions.

If i was to ever LT a woofer,id do it with this ,or a similar one.
a 15" with 27mm xmax..

The sadhara looked expensive enough.

Not the cheapest route however.

Have a chat to the guys at HOMETHEATRE forum.com and see how theyve done it.

I dont equate LTs with High spl...high being 120db in the sub 30hz region.

Good luck!

You do know that certain frequencies, when loud enough, cause physical distress?

MITMechE · 31st March 2004, 10:54 PM

Not sure about dB levels, but sub frequencies (under 100hz) are about the natural resonance frequency of much of the body.

I probably woudn't want to sit in that chair.

Or it might be great way to prep for a colonoscopy.

On a slightly more serious note, surely 1 Tumult would be quite enough.

No, I changed my mind. 2 Tumults is a great idea: our local economy definitely needs the boost.

Aka the 'brown note' ~8Hz........

Perhaps an efficient cure to calm hemorrhoids...
...Don't forget to patent it !
