Well I didn't go out tonight so here is the info I'm using for the linkwitz spreadsheet I have. Name - Tumult Number Of Drivers - 1 Fs - 19.00 Hz Qms - 4.3 Qes - 0.39 Qts - 0.358 Vas - 160l Xmax - 34.0 mm Re - 3.2 Ohm Impedance - 4 Ohm Diameter - 35.0 cm Wattage - 1600 w Sd -...
I'm at work at the moment so I can't double check myself. I wonder if I did have the subsonic/input filter activated and didn't realise it. I don't think so becuase I'm sure the buttons said "enable" on them. To me this would mean they are currently disabled. I won't be home till nearly...
After doing a bunch of reading this has me interested. Now the deal would be this, 1. keep my current 110-115L sealed box. 2. replace the Keiga amp with the ADA1200 amp from Adire. Using the linkwitz spreadsheet plugging in: Box volume = 115L Target Fsc of 15hz Target Qtc of .7...
Tumult is sealed 110L(or as close as I could get). I'm curious if anyone thinks going from a Keiga 1000w plate amp to something like a Behringer EP2500 or QSC RMX 1450/1850 would make any noticeable difference. The problem is it seems like when listening at loud levels and a large explosion...
I gave my father the plans I had drawn up for the dual PR'd Tumult box. That's when he showed me a sketch and asked what I thought. It looks kinda like one of the B&W speakers, rounded or oval back. If you think of an oval or egg shape with one end cut off you should get the picture. This...
OK here is a link to a page with what my father had in mind for the braces: http://home.mindspring.com/~c-b-dixon/ The drawings aren't exact but close to scale(the top drawing is a "from the top" view). Anyway when we did the sealed box(that's what the photos are of) we ran braces from side...
Well I'm looking at building a PR'd box to replace my sealed Tumult. My question is if it would be better to go with double walled(1 1/2" total thickness)13ply Baltic Birch or single walled(except for the speaker baffle) and use internal bracing? I have access to a full woodshop thru my...
Brian, No at this time I don't have an EQ on it. I was looking into a BFD but never got around to buying it. Nat, I'm glad to hear you're happy with the switch. That gives me some incentive to build a new box and give it a listen. If I could get away with a ported box I'd already have done...
The Tumult has been out awhile now so hopefully someone has made the switch. For anyone that has gone from a sealed setup to ported/PR's how much difference did it make for movies? As far as music I'm more than happy with it sealed but would like some more low end for some movies. Right now I'm...

This should be the direct link to them. It's on page 2 of the fuses section. For some reason when you use http://www.evaluecomp.com it redirects to the auctionworks store front but it is his page. It doesn't specify on the page what voltage...
Ben,
OK I found the reciept. Website is http//www.evaluecomp.com the guys name is Larry Stevens. I looked at the site real quick and it appears he still has some in case you can't find any locally.

Ben,
I'm still at work but I got online and did some checking. Here's a partial listing of Wickmann dealers.
http://dilp.netcomponents.com/cgi-bi...artnumber1=194
I can't remember the exact amp rating but I *believe* it's 12 amp. The closest they have is 12.5.
Part number would be...
Ben,
I got mine from a guy on ebay, evaluecomp was the user name I beleive. When I get home I'll double check for you. I think it cost me ~6 bucks plus shipping for 10 from him. When I was looking I found a couple stores online that had them but can't remember their names. They were a bit more...
I've talked to Kyle a little on this but figured it wouldn't hurt to ask here aswell. I'm not exactly sure what's happening but I've had 4 fuses blow on the Keiga amp.
Now what's weird is that it doesn't do it while watching movies but it appears to happen during the day or night when we...
OK I admit it, I was missing something lol. I don't know what I was doing before but I just got done re-running the numbers in unibox for an ebs Tempest and a 150L Tumult tuned to 18hz. The Tumult shows 3-4db more output down to 20hz then drops off pretty quick. Below 15hz the ebs Tempest has...
Does anyone know if it would be possible to disable(or change) the rumble/subsonic filter on the Keiga amp? I have one I'm using with my sealed Tumult currently. Was planning on getting 2 18" pr's from Kyle and making a new box for my Tumult. I want to remove the rumble filter so I can tune...
OK this is going to sound dumb but what exactly will more do for me? I'm planning on buying a BFD and getting the response as flat as possible with my current sealed Tumult and matching the levels of my mains. As it is(may change after getting the response flattened out?) my ears reach their...
You guys were right, it appears to have been the amp clipping. I did have the 25hz boost on, when I turned it off I didn't hear the noise during that scene. After having this thing a bit now, I'm still undecided if I should have went with 150L with dual PR's for even more impact on movies...
It's a 115-120 liter sealed enclosure with the keiga 1000w amp. I set the level using rs spl meter and avia. I don't have a bfd yet or taken any room measurements really. The sub sounds great except on the scene in the Matrix where the helicopter crashes into the building. It makes some noise, a...
I've had the driver since December so it's about time. Here is a link to a few pictures of the box. http://home.mindspring.com/~c-b-dixon/ For some reason the top looks kinda orange in a couple photos but it's the same stain as the sides and only slightly darker in person. The sides are...
If my last post is not allowed, mentioning a name and price let me know, I'll edit it out. I looked at the stickys at the top of the forum and I didn't see anything saying it wasn't allowed but I could have missed it.
Seth, I used t-nuts after sending an email to both Kyle and Adire. Kyle said I didn't have to but Adire said they would recommend them over course thread wood screws. I can always knock them out and put something else in like insert I guess if it is truly an issue. Pete, It is 13ply Baltic...
Seth, We used 10-24 t-nuts and made the cutout 14 1/8". It fits great, there is very little extra room, it is possible I used a smaller dia. router bit than the jig was designed for. How do you folks drill the holes for the t-nuts? Since we couldn't do them on the drill press and it was to...
Let me rephrase the bracing comment. I hope it's enough so that the lamp and anything placed on it won't vibrate. I'm sure the panels won't flex. What I'm not sure of is if items setting on a sub vibrate because the panels flexing or if it's resonance or something. I'm sure that comment shows my...
I was hoping to finish before I left on a family vacation but things didn't work out. Box will be 3/4" Baltic Birch with 1.5" speaker baffle. Volume will be 117L - 120L net. It's hard to see but we did dado grooves for the large internal braces and baffles. We simply cut the small pieces...
Well we(father and I) started cutting today. I decided on 27x22.5x19 external. I decided I really would like to try a low Q design(unibox says 146l to 125l for .5 to .52 qtc). My internal dimensions are 24x21x17.5(we're doubling up the speaker and amp baffles). What I had planned was 3...
Good news is I got a bonus from work. Bad news is this has me wondering if I should build a 120L(may be able to squeeze out 130L) PR Tumult or stick with my 85L sealed plans. The sealed box I have planned will fit under our current end table. If I go the PR'd route the enclosure would have to...
Sitting in a closet(in original box/crate even) since December. Planning on the 1000w plate amp from Kyle in a 85l sealed box at first. I'm one of the few who got one in the first shipment and have been waiting on this amp to become available. Brad
