Ricci has a XXX 18. He's bringing it down my way on the 18th to have a run at my subwoofer shootout. From the looks of it, it has crazy throw to it. Apparently sounds very good too. Not quite as clean as a LMS, but very close.
A bigger box would give you more low end extension if this for HT unless you have a box size restriction.

Two 12" woofers will almost always work out better than one 10". However, the Daytons have very low excursion so you will need to keep that in mind. What is your budget and what is the application? Maybe there are other (better) options?I was looking at the RE Audio SE 10" sub for my room, but was told that 2 Dayton 12" calssic woofers would be better. Do you agree?
Thanks
My max budget is $425, but I would like to keep it below $400, if possible. I was thinking about getting the CSS Kit found here for a HT application:Two 12" woofers will almost always work out better than one 10".

Ok. If the box is big enough, could I just run two Dayton SA240 watt amps to it, and have it equal close to the output of the O Audio amp?OK, now we are talking about some good woofers. The Shiva-X is in my opinion, one of the best values available. It is an AMAZING woofer for the price! With 27mm one-way excursion and 600 watts power handing, it can easily best almost all of the woofers we have been talking about here. There is a lot of support for the Shiva out here on the forums too. It is definitely one of the good ones. However, I would give it a little more power than that Dayton amp if you can afford to. The O Audio 500 watt amp is very nice (I have one) and would mate perfectly to the Shiva but that pushes you right to your budget limit.
I have also seen the CSS stuff but don't know much about it.

No, I don't have the Dayton amps. And I was just wondering I it would be possible, and I dounbt I would hae done that anyways. The only thing I like about the CSS kit is the fact that you can adjust the PR's very easily, but, is the 300 watt amp any good for it? I see that is says that the amp has been modified. Do you know what this means?Well, since the Shiva-X is a dual coil woofer, you *COULD* do that (if you were absolutely sure the amount of power going to each coil was the same) but it isn't very elegant or even advised. Why do this anyway? It isn't cost effective. Two of the Dayton 240 watt amps will cost you $218 plus tax and shipping. The O Audio amp is only $229. The shipping would also be less with the O Audio because it is a LOT lighter than two of the Daytons. So basically, it is a wash price wise and the O Audio amp is WAY more energy efficient than two Daytons. Do you already own the Dayton amps or something?
Before I would wire two Daytons to the same woofer, I would just suck it up an use the lower power of one Dayton if I really had to go that way.

How much is a PR for the Shiva-x?I don't know how the 300 watt amp has been modified. Hopefully, they added a high pass filter so you don't blow the woofer below the tuning frequency but my guess is the change is simply moving the bass boost to a different place and level based on the recommended cabinet size and tuning.
If you change the tuning of the PRs by adding or removing weight/mass, you will likely want (need) to change the cabinet size as well. These changes have to be made carefully and should be modeled first to make sure they are going to work.
If you want to customize the tuning frequency of the Shiva-X box, that is easy too. Just add a PR ($$$) or a port (cheap) and tune it to whatever you want. Again, modeling is important before you get into the complexities of changing tuning.
The simple build is a sealed cabinet and it would sound very good too. If you still want more output after that, you can always move to a ported cabinet or add a PR later. ...Or even build another sealed Shiva-X later. :bigsmile:
