post #31 of 77
Nice.
post #32 of 77
I like the boxes. Did you get a chance to hook them up. When we talked about the 2242's a while back,you got me to looking at the 2241 and 2242 all weekend. I should have just continued to look at those drivers all weekend instead of venturing out in unknown waters.

Anyway, looking good and waiting for impressions.

One of the drivers is here and the other one just got shipped today. As soon as my duratex gets here, I'll have them all done pretty quick since I can use out paint booth and bake oven at work. Shipping's been a bit slow because of Christmas but it's starting to all trickle in. I hope to have them up and running the weekend before christmas. I'll have a week off and want to get it all setup the way I want and take some measurements.

Are you guys hooking into the front main preouts or using just the lfe ? I am just using the lfe here, hope I didn't confuse anyone.The preouts would be fine for music for me, but for video you will be losing 10db digital, I am pretty sure. Robert, very nice setup you have there. Are you still happy with the qsc rmx amps ? I just picked up a used 4050hd , so far not to impressed with it. Either that or my 12 yr old subs use a lot more then the 600 watt rms rating.

The 4050HD outputs 800 wpch @8 ohms and 1300 @ 4 ohms. Are you sure you have the dip switches on the back set correctly?
Additionally, to get full output from mine I have to raise the input signal using an Art CleanBox. My Yammy receiver just will not drive a pro amp to full output.

I'm going to try it with the pre-outs first. Thats how I'm hoping to use them.

Ya , I tried it in stereo mode first with 2 4645c's per side and it seemed kind of weak. Now I have it bridged running a pair of old school rockford hx2 18''s , and they seem to really suck up the juice, more so then the jbl's.
post #38 of 77
Question? What amp is powering the Jbl's. And also, pre amp. Is the voltage enough to drive the amp. I had that issue with the pre amp I was using a while back. I needed to add something to step up the input and voila, it worked. Just kicking out ideas.

I am using two ep2500's for the jbl's . One bridged per pair .The preamp is the denon 4311, I have used it with like 5 different amps, never a problem with not enough voltage. Lately I have been using the opening seen of immortals to test the lfe. I also found a sweet game for 360 that has some nice bass, its called sniper elite v2, if you like shooting games, check it out. N8 , looking good , let us know how you like them.

i will be using a bridged ep4000 and an integra 80.3. ive got cleanboxbif needed.
post #41 of 77
I was just asking because when I hooked my Crown Itech8000's to my Integra, the voltage was far from adequate and I had to get a MIC2200 and it even had a HPF that I needed, so I won both ways with one product.


Keep cranking,

It's funny you should say that. I was just going through a bunch of boxes tonight and found my old mic2200 that I had though I had thrown away lol. Well, at least it give me a few options!

Well, I have the subs painted and built. I had about 20 minutes to mess around with the subs as I'm leaving in 20 mins for a xmas party. All I can say so far is Holy freaking S#$%!!!! This is exactly what my system has been missing, that pound you in the chest thump, it almost sounds like someone is throwing rocks at the wall. It's a solid bang with no lingering echo. I know that's also to do with how small the boxes are but color me impressed so far! I can't wait to get these running with the Noesis!!! I don't have my Noesis yet but Jeff said they will be shipping on Monday. I'm still waiting for my minidsp but I will get it up and running with the mic2200.

I'll take a few pics when I get home tonight of how they turned out.

Here are a few pics. The position they are in now will stay the same and the Noesis will be put on top.

Looks like you're off to a great start. Think you'll need eq to get them down to 40hz?
post #46 of 77

I'm planning on cutting them off at either 50 or 60hz. In these boxes, I'd have to EQ them quite a bit to keep them flat to 40hz but thats not really the intent anyways. I just want to extend the mid-bass of the Noesis to about 50-60hz and get some chest thump action. I'm planning on a 60hz - 300hz. They model quite well in that range. Should be a fun experiment. For the past hour or so, I've been using them as full blown subs and am very impressed with them so far. The upper 80hz range is awesome. Can't wait to see what they can do even higher!

Those drivers just look fabulous in there. I think you made a fine decision in the design and use of driver

Looks good, ya man run them to 120hz the pdf of the driver says peak spl of 134db above 100hz. I have some older mach 5 mj 's in almost the same size sealed boxes,way to boomy compared to 2242.

We will have to agree to disagree. I've never seen pics of your HT. Wondering where all them subs are. tongue.gif

And I don't really hang out in either the "JTR thread" or the speakers area. I'm DIY all the way, son! biggrin.gif

Hey N8, did you try running these guys up to 300hz yet? Still impressed?

I just got my speakers today. I'm still waiting for my minidsp and some wiring forn the subs to be used how I want. I now remember why my Mic2200 was hidden in a box, the damn thing doesn't work LOL
Above the ceiling tiles are 6" of acoustical foam. My bass traps and corner traps are not in this pic because they are out getting new fabric put on to mach my walls.

Here is a couple of pics for Scott lol
