Exactly, why go to the trouble... and create more things that can go wrong... and create the need for more EQ'ing / xovers...

And more, and more, and more... Bullshit...

If you don't absolutely NEED to. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Excellent things about IB, is it extends very well...

Tis what I am banking on. This setup is more for movies than anything. I understand these won't be the most accurate for music but will do the job.

Here is a picture of the beginning of the manifold. I hate stopping midwork to take progress pix, so you will have to bare with me on no play by play detailed log. I got the meat of the manifold pounded out. It is 72" x 16.5". Tomorrow I work on cutting out the speaker baffles and bracing the inside with dowels. Next weekend I move to the attic and start pounding out the install.

Looking good, should be crazy lowend with all those driver coupling like that....

As promised, I got the baffles cut and bracing put in. I will probably brace the outside with 2X4 framing once it is situated on the joists. So here is where I sit for now.

Very common in the IB community of HT setups actually. Some use 8 avalanches. In an IB install output isn't all that great, because your driver will reach it's mechanical limits way before it reaches it's thermal limit. What you do get is really low extension though. So to make up for low output you just double or quadruple the drivers //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

The excessiveness is for dynamic transients of info below 20 hz in movies //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif I want to feel the movie proper. I will have 2 towers that contain 16 4" NSBs and 12 tweeters each in a line array, so when I do listen to music they should be able to keep up nicely with mids and highs.

When are you going to get them line arrays done anyway, i got mine done //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif them NSB's are by far the best .49$ i have ever spent,im glad your doing 12 tweeters per tower, although im not complaining about my measly one per tower, still incredible speaks.

Update time. This update brings many changes thanks to an oversight. When I first went into the attic before starting this project I mapped out and measured where I wanted this and how I could get it there. The original manifold I made would have gone there no problem, however I never bothered to pull back the insualtion when I was measuring and planning. When I got ready to huff this monster up there I scooped away insulation from the area. It just so happens that this spot has every wire in the house intersecting there going to my OnQ panel(Lan, Alarm, romex, cable, surround sound, and something that I have no clue to) in the master closet. There wasn't enough slack to reposition them either. I wasn't rewiring 20 different wires for numerous reasons. So a revision and modification to the manifold was necessary. So that is where I am at now. A new manifold ready to go in tomorrow.

OK. It is all finished, but unfortunately I had the digicam crap out. For some reason it is making weird lines across. You will all have to be happy with pictures of progress from last weekend when I got it installed in the attic. When I get a new camera, I will post the finished pictures and the grill I made.

Preliminary thoughts are that this thing goes very low. Its presence is not obnoxious like most peaky sealed and ported enclosures. It blends well with the other speakers. I will need to play with it and fine tune it by figuring out the best settings for the para=eq and crossover. I put in a few select movies and tested it out. This subwoofer setup isn't heard as much as it is felt. walls shake and a heavy feeling comes across. On music it is just absolutely flat. Not one note comes across much louder than the rest. Response in change is quick due to an infinite baffles really low group delay. I will get more in depth when I can put up the finished pictures. By then I should have it dialed in all the way and tested a lot of material.

I may switch amps. I have tested a lot of material today and these things barely move. This amp goes into soft clip protection well before these drivers think of crying. I think I can use a bit more power. Plus I am pretty sure I will need a more robust seperate eq unit anyway. This will do for now, but I can already tell this will be a constantly improving project lol.

I need to get started on my line arrays soon to compliment this beast.
