OH!? A few of us spoke about your situation and thought we wouldn’t bring up adding dual GH until you were done with your current project. We’re thinking just for smoothing of course. LTD is already mocking them up for yuh so you can transition in a good manner and not give chal a chance to close shop.

Geez Husker I was just playing. I should check out Notnyt's build though.

So, I'm going to have an open theater concept with a small stage and AT screen......

Room behind the screen can be modified to fit sub requirements.....

If I'm filling a basement that will be roughly 1800 sq ft, with probably 1100 of it or so open and including the theater.....the rest will be bedroom/storage/etc....

Ideas to fill it well? I'm thinking I'm going to have to pull the 4 UXLs and go with a couple horns and a couple ported, or all 4 ported.

I know Archaea, but if you switch I can too!

I've got four of the UXLs ported to around 15hz and all nearfield about a foot behind. Lots of overhead .

No build thread, but my enclosures are the same as Jbrown's. I'm driving each one with a channel from a crown xli 3500 and a crown x4000(same amp) I was using two FP14ks but being nearfield I've had no issues with lack of power.

OK, these boys are coming out of storage in about 4 weeks when we close on our house.

The room they will be in is essentially 1500 square feet of open floor with 1/2 having 16' ceilings. Huge area. I'm thinking for any punch I'm going to have to go #ported . @Archaea .

So, I have 4 of these in sealed boxes, one of which is freakin' siliconed in because I'm an idiot.

Cut that box and get the driver out?

Do two sealed and two ported and see how I like it?

Ported box designs to utilize?

My other options is leaving them sealed and rolling with it, I'm sure it will be good enough. These subs are all out in the open in a nice room, would be nice for them to look sexy.

I should slap myself for selling my Crown XLI 3500. I did it on a whim and went back to a Inuke 6000. Ugh. Slurred bass and loud fans were my reward.

I'm getting another Crown XLI 3500/X4000 as soon as another one pops up in the classified section. They do a very good job of powering subs and their fans are ultra quiet. Definitely a underrated amp in my opinion.

Glad you're getting back in the mix. You've gotta large space to fill so IMO, you'd need more displacement than four uxl to reap the sealed benefits. There are all kinds of Marty sub variants to pick from. I went another route with larger and lower tuned cabs. Search LTD-M18. Currently I have two up front and two near field. Near field makes a substantial difference in impact if you can accommodate.

I have given the ULF stuff plenty of chances to floor me and I always come away thinking......that was pretty cool, but I still want to make sure the normal LF frequencies are super super strong before I put money into ULF.

I also think many of the ULF experiences are actually resonances in theaters that have loose materials whether it is the floor or walls or other objects.

So I am not saying don't go after ULF. But, just make sure everything else is covered first.

Which brings us back to your boxes. I don't know how the 4 sealed will behave in that space but why don't you just find out and do some measurements. Mess around with placement and then decide if you want/need more output.

Personally, I would not hesitate to give up 15Hz and below for earth shattering 15Hz and above.

So, I have the clone amp about 1/2 on the gain nob, and J River at "reference" and I'm totally happy with what I'm getting in room after re-cal with Audyssey on the receiver and a few adjustments in the J River settings.
In fact, sometimes I turn it down.

Now, I haven't yet tested the limits at all and haven't gone for @desertdome weird chinese organ drums music or the ULF of some of those demo movies but for great music and very satisfying movie experience in a large room - it is fine.

Just counting down the years until I get after that basement. Tree house and landscaping not to mention garage organizing is going first.

I don't think I'll be modding the 4 UXL-18 boxes at all for now.

Updates:

My neighbor was shipping through a TFS9000 or something from JBL for his company and wanted to test it out, in my quest to see if I need to get some ported beasts in here. It was solid but I'd need to get a hole cut in the wall and hide it if I wanted to stay married.

The clone finally died. Electronics store said $650 to fix so I just have it in a box now. They took some dead diodes out and said caps were fried. Don't know what to think, but they work on everything so I trust them.

Bought @Archaea CV5000 he wasn't using, finally got it set up. At first workings after EQ I kicked the Audyssey gain for sub up 2.5 db to get the punch I want, and running the amp set on unity gain or 0. Seems smoother than my prior settings with the clone haven't pushed it so far. Glad to have subs back!
