Paradigm Sub 1 or Seaton SubMersive HP? - Page 2

That looks really sharp Sam. Congrats!

Sam did you get your Sub set up properly yet? i'm interested to hear how it sounds in your room, i have a room about the same size and i am thinking about ordering a Seaton also, not sure if i'll go with the HP
or the F2 yet. Better for me, i live in the same area as Seaton subs so that's a big plus for me, i have not heard anything negative about his subs.

You guys are jumping to conclusions. The FV15HP is ported so it will have a boost down low from the port. If you look at the sealed LMS 5400 the Sub2 is very close to it and down about 1-3 dbs in the 16-50hz but equals it down low. The LMS 5400 will be stronger than a submersive, XS30, or many sealed subs. The XS30 will get clobbered under 20hz by the sub2. The ported XV 15 is down 4 dBs at 20hz already with a port! A port adds huge output at tune so take that away and add another driver and you are down a good 8 dBs at 20hz and worse below that. Now, it does not take the sub2's money to get there and you can have 11 XS30's for the price.

How will it get clobbered by a Sub2? According to Tom at PSA below 20hz a XS30 is stronger then the XV15. Sure It might be a few db down on the Sub2, but clobbered? And duals should equal it, a Sub2 doesn't even have more output of the FV15HP, so once again how will it "clobber" the XS30?

I'm basing all of this from the data-bass.com measurements.

This is pure speculation but if you go to the data-bass.com page and overlay the measurements from the Sub2 and the XV15 and compare them from 40hz and down the Sub2 never really has more then a 4db advantage. And also keep in mind that when Josh took the measurements he made a comment in the Audioholics forum that he left the sub in the downward firing configuration and if he had taken the bottom plate off and fired the sub directly at the measurement mic he would have seen an increase on output numbers by 1-1.5db. So if you take that into consideration of the numbers between the XV15 and the Sub2 really it only holds a 3db advantage over a XV15.

The XV15 only has a very slight advantage over a XS30 in the range of 20-31.5hz according to Tom. below 20hz and above 31hz the XS30 has more output then a XV15 and would be very close to the Sub2. And also has a peak output of 122db above 40hz which is also very close to the Sub2. So how does a Sub2 clobber a XS30? I could be way off of this MK, if I am please explain it to me. I would be more then happy to hear from you as I know you clearly know your stuff.

I was using Data-bass as well. Well, the XV-15 uses the same 15. Dual sealed 15's would have less output at and near tune than a ported 15(same driver of course). A port adds close to 10 dBs at and near the tune, sometimes more. Dual sealed drivers equal 6 dBs more only if power was doubled. The XV-15 is tuned to 18hz so those 16-25hz numbers will be more than what a XS-30 will do. Below that is where the XS-30 will begin to get louder. BTW, this is all just guessing, so I would subtract 4 dBs from the XV-15 numbers to come close to a XS-30 but only at 16-25hz, maybe just 16 and 20hz. Above 25hz it will actually louder than a sub2 but we have enough midbass monster subs, don't we? The LMS5400 is a great performer with the best 10hz performance and the sub2 is very close to it. So for the low end it is an awesome performer but costs too much, way too much. That is all. When I say clobbered I am saying it would be about 8 dBs down at 16 and 20hz based on what happens to sealed and ported normally(XV-15 is 4 dBs down with a port). If I port my subs I would gain huge output at and near the tune but of course creates a huge peak in my sealed room. That is all, the XS-30 is what, $1000? You can buy 9 of them and game over. I was just saying for a single small sub it is an excellent performer. Now the sub1 would be what, 3-4 dBs less than the sub2.

I personally would use the measurement graphs of an Empire to compare with the Sub2 to get a better idea of how the two would compare with them being a very similar design. And then factor in that the XS30 is suppose to have a few db more output. Two XS30s would certainly at the very least equal a Sub2.

Sure it has great performance for a small sub but shouldn't for 9 grand?

For 9 grand it would have to knock my house down. I have small sealed subs now for much less. Factor in my amp and each sub cost me $625. Of course that was DIY so not fair. BTW, I loved my SVS 16-46cs+ subs so I am sure the power sound subs are awesome.

No you're right DIY is a great value option. For me I was in on the pre-order pricing with the XS30s so at only $1050 each factoring in the build quality and 5 year bumper to bumper warranty on them it was a no brainier too me.
