best to stick with sealed+sealed or vented+vented with our products. You CAN make vented+sealed work and perhaps work very well. But, barring rare exceptions, you will be better off sticking to similar subs.

You would've upgraded in a week or two anyway...

Being paranoid in this day and age is probably a good thing. You can't be too careful. Either one of you could be taken for a ride.

Welcome to the fold my brother. I can't wait to hear your thoughts. I would love to be a fly on your wall when you get them set up and crankin'...

You'll get extension down to the 4hz to 7hz range with just *tons* of mid and upper bass slam factor. You'd probably be looking at 112-115dB all the way down to 10hz....mid and upper bass headroom? 121-127dB.

Which extension mode are you using with the 1ex?

exactly right on the upgrade. That's also why I just went with 2 right off the bat. I know me. this is what I am eventually going to do...just get it over with. This way my wife doesn't have to listen to me talk (to myself) about it for that whole week before I upgrade anyway.

Considering my room is less than 1600cu.ft, i'm hoping for some literal "heart pounding action", as 'they' say... haha

At 1600 cu ft, you're going to get quite the experience.

I hear you on that one. My room is 4300+ cu ft and opens into a large two story foyer on one side. I still get impressive bass at my listening positions. I have pushed 118 dB at -7 dB on the dial... 13 feet away from my subs.

I hate all you guys with your medium sized rooms. I'm pushing nearly 10,000 cu ft in my open living room.

Sorry, I had to.

that sounds pretty insane, talk about beastly! I am running one port open right now. I measured with an spl meter and actually get more 20 hz output out of my dual xv15se's in the 6000+ cu ft living room that I do with the 1ex in the <1000 cu foot room in max extension mode.... By quite a bit too (4db or so). I find that interesting, and surprising.

I'm not surprised. The 1ex is a good value at 599 to be sure....but it's really not comparable to the XV15se. (I know a few insist otherwise but their POV is based more on personal grudges than anything of value to other forum members imo).

In 1 port mode you might be running into quite a bit of ringing too.

http://www.data-bass.com/data?page=system&id=58

That hump in the response down low matched with the sharp "knee" is sort of worst case for a smaller room like yours. Instead of taking advantage of the room transfer function to get 5hz extension you may be getting into all sorts of audible ringing/decay issues.

If you have a chance to try a sealed sub that has a shallow rolloff I think you would like the effect. The sb2000, xs15, ect.

I was surprised for a few reasons 1) the outlaw is a larger sub than the xv15se (enclosure wise) 2) the room for the outlaw is 1/6 the size. Even subtracting the effect of dual xv15se, it still reaches higher spl at 20hz in a room 6x as large! Seems crazy out of a smaller box, even if the driver is bigger.

Couple questions for you:

1) I was not doing bursts testing, but rather a continuous 20hz sine wave for about 30 seconds (hopefully this isn't hurting the sub). Is there any sort of conversion to max burst performance? (ie +3db or what have you).

2) what are we considering when we claim things provide "extension" to a certain frequency? Is there some sort of standard spl value to consider something sufficiently extended?

Edit: in regards to trying sealed subs in the small room. I may just try that one day, but I won't lie, part of me fears this will lead to crazy upgrades in the big room trying to match it (something like dual stacks of Triax's!)

Or add a triple xs30se. I will post my frequency response with the setup pictures when I get a chance soon but on a quick note - I have a 4300+ sqft room with extensions to rest of the home and I have a triple xs30se. I am loving it, especially for the music. It is like a hammer dropping with a thud and stopping abruptly right in front of you. No extraneous ringing, zilch... nada! It sounds wonderful. The couch, the cabinets and the wooden floor on your feet vibrate when you can't hear audible sounds and the room is dead silent, it feels like the room is awake. One thing that surprised me was when my wife asked why our wall hanged portrait in our second level bedroom was tilted. I knew the second level floors and walls were vibrating but didn't think the sub were capable of tilting the wall hanging picture. I feigned and asked her whether she moved them!

I try to keep a tab on this forum everyday, send me a pm if you have questions about my setup or user experience.
