Tumult reviews with measured performance? (1 Viewer)

Does anybody have any idea where I can get some "real-world" numbers for "in-use" Tumult performance? I've seen reviews pretty much saying "sounds great, low distortion" but that's about it, as of yet have seen no real numbers for it's output.

Does anybody know where I can get some figures on what a sub with this driver actually does? Say, 70-80 Hz down to 10-20 Hz or so?

There's quite a bit of interest over at the Klipsch Forum about this but nobody's seen squat yet...

Thanks,

J Stanton

Nothing yet that I know of. Takes a while to see that kind of thing in the DIY world, if ever. There's a new thread started every week about this, so something may pop up eventually.

I've almost got my Tumult enclosure finished. I now need to pick up an amp capable of driving the beast. I would prefer one with auto power on when it receives a signal. Kinda hard to find a 1,000 watt amp with this feature. I was hoping to use a Buttkicker amp, but haven't been able to find anyone running it for sub use.

Hopefully in the next three weeks I will have some numbers.

The new Keiga plate amps have this feature and are 1000 watts. Of course if you are using an outboard amp I'm not sure what models would have that feature.

I checked out the Keiga on your site. Am I correct in thinking that this thing is sealed. Would I need a subenclosure in my enclosure for this amp? When I mean sealed, I mean really sealed. Will this amp withstand the rigors of being mounted on/in a Tumult enclosure?

That seems like a lot of abuse to put any piece of electronic gear through. Doing the equivalent of beating on it with a hammer, year after year, just can't be good for it. I prefer my amps on a rack or tucked away in a closet, safe from kids, dogs and Tumults. :D

Since this is the DIY forum, for not much money you can rig up a relay to turn on a cheap pro amp when it gets a 12V signal from the trigger output of the pre/pro. No experience with these commercial models but they look decent.

Greg,
The entire back of the amp is covered by a rigid plastic housing. This housing is one complete piece and the only way that it could leak is through the cables leading out the back which are siliconed in place with a strain relief bushing as well.

Dennis,
This is a very stout amplifier and I would not feel afraid about mounting it on the back of a well built enclosure.

Kyle, send me one and I will test it out for you. I'll hook it up to the vacuum system here to see how air tight it is. Just to be fair, I'll use the calibrated baratrons to measure absolute pressure ;)

I ordered the Keiga last night. I'll find out how well its sealed soon. It sounds as though its sealed pretty well.
