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...

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...

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...

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...

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...

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...

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...

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...

Are the high power plate amps still in the works or does it look like it won't be a viable venture? If push comes to shove I could always save a little longer and use one from Adire if I can't talk my wife into a rack amp. Thanks, Brad

I placed my order for a Tumult. I'm going to build a sealed .577qtc box first. If that isn't enough I'll look into PR or wrapped/bent slot port box like Dan Wiggins mentioned in another thread. I would like to ask a question though. When modeling with unibox4.0 if I enter the specs for...

Is there anybody that's been in a similar spot. Wife says one or the other. We had a Barco Data 801s for a short time and it was great but not exactly practical. We've got a 32" xbr at the moment so picture is good just not very big. With our current sub it leaves a lot to be desired so I'm...

My plan is to use my radio shack meter to take measurements with during movie watching. What I'm hoping is to find is the approximate volume we normally listen to movies at. We currently have a Paradigm PS1000. It doesn't go very low(some measurements I took using avia gave very little sub 40hz...

It's oak and stocked in 2x4 sheets. From reading the forums marine grade 3/4" is recommended but locally I've only been able to find 7 and 9 ply 3/4" marine grade. Some places are checking into getting 3/4" 13ply but it would be a special order in all cases. I've found 3/4" 13ply Baltic Birch...

linktranadv28.11 for excel is the spreadsheet I'm trying to use. I'm confused by the EQ Information box. It asks for "power applied" and the popup says "Enter power applied that will be multiplied by the EQ". What value do I put here? Using a Qsc830(think that's the model) amp as an example for...

I'd like to know if anyone would give their input on this. I'm enjoying running the sims as best I can but at the moment my computer just does not want to work with unibox and excel 97. Half the time when I make a change it gives the "illegal operation" and closes unibox. Since lspcad is...

I was bored last night so I read through the build a subwoofer thread and noticed something. A few people mentioned building a dual. I just had to ask if anyone was really planning on building a dual(sealed or pr). If I understand correctly that would be aprox 5 tempests? Even for this forum...

Well if work slows down this week I'll be ordering an amp and sub. I've got the sonotube and mdf already. I realise this is a somewhat personal/loaded question but, any opinions would be helpfull. Room size is 15x13x8 with a 7' opening(on 13' wall) going into dining area. Also has a 3' opening...

Just wanted folks to know that I did appreciate the answers to my questions in the 1803/maelstorm thread. Things got real busy at work and home. Anyway I ended up buying 6' of 24" sonotube(1' of 30" as well to verify if it would fit thru interior door). I haven't bought the speaker(s) yet but am...

I've read this forum for awhile now and had planned on building a tempest sonotube based on some of the designs here. With the maelstrom and 1803 available for use I was considering using one of those in aprox 14cuft. Problems/questions 1. I have the spousal ok for a tube not a traditional...
