It is going to be a standard Exodus product. We have bumped the overall diameter up to 21", since 18" just wasn't SICK enough. Parameters are going to stay much the same except Sd is about 30-40% higher. Vas goes up too and the box size the driver will be optimized around is going to jump about the same amount, 30% or so. The PR version should still work good in 8-10 cubic feet and the sealed in even smaller so this driver will work in reasonable enclosures and deliver output unavailable in any single production driver on the planet. In fact, I think it eclipses any TWO production drivers on the planet in terms of pure swept volume.
Sure.... and you are right, there is no reason it couldn't be used IB. My statement, if I remember right, was aimed at someone asking about the Maelstrom-X in an infinite baffle. The only basis for my statement was founded upon the cost per unit output in that situation. For someone buying the Sicko-21", the value is probably not at the top of their priority list. I still think that if you are doing IBs, you should consider drivers firing in opposing manner. In other words, you would want at least TWO Sicko-21"s mounted in a baffle firing at or away from each other. You will also find, that as the driver size increases the baffle opening needs to increase also. For those reasons I normally recommend people keep their driver size limited to a 15". Four 15"s mounted in a baffle allows you to keep the baffle opening small, it fits between stud spaces and you would be better off in terms of in-room response by having multiple four driver arrays of DPL-15s rather than a single Sicko-21" manifold.

Thanks for the response, Kevin. Actually I've kind of got something rather, uh, sick, in mind for my theater sub (assuming finances come through). The theater will be designed around this sub, so no concerns about stud spaces or manifold openings or anything like that. They'll probably be mounted right in the wall. And what better driver to use in a "sick" installation than the "Sicko"?
You are our target customer davepete! I heard this whisper one afternoon...... "build it and they will come". So I'm been on a mission ever since.
We will probably do the 21" first, with the 18" following within six months.
Hi Kevin,Have you decided upon the cone material and configuration yet? I believe you were previously looking at various honey-combed designs, perhaps having a one piece approach as opposed to a cone/dust cap implementation. Also, are you still considereing a 'flat' piston, or are you now looking to a more conventional cone?Good stuff here; btw - the Face gear is great!Larry
Crikey!
Kevin,You know I've been trying to avoid going bigger with my sub!!! You've got to stop showing me this stuff!!!!Basket looks very well engineered and that looks to be one impressive motor!!! Can't wait to see what the actual paramaters of the first samples are.
Kevin, I'm not sure you'll be able to answer this yet, but using the stated 9-10 cu ft box, do you know roughly what kind of tuning point you're shooting for? With a driver of this kind of raw output capability, a good low tuning point would make the best use of it. Will it work well tuned to, say, the 10-12 hz range or so in an EBS alignment? If so, will it do that in 10 cu ft, or is more volume needed for use as an EBS?
