Thomas-W, where are you?
post #602 of 615

I have decided to take Thomas-W's advice and build a manifold on my door to house (4) Fi IB3 18's on the top and make 2 slot ports on the bottom out of the rectangles already there. The door is 1.25" thick, I will make a template/face of the entire door adding .75" to the thickness. I'll make a 25"x25" panel to plug the ports so I can run true IB as well. Here is a pic he suggested for me.

I will begin tearing the Twin Towers down tomorrow and use the wood to build the manifolds and ports. It will be nice to get the EP4000s out of the HT room cuz I haven't done the fan mods.

The IB3s are custom dual 4 ohm, 4 layer IIRC, series/parallel 4 ohm bridged per EP4000 (2 EP4000s, 2 subs per amp bridged).

I am wasting and tearing apart a very wonderful performing pair of enclosures. Under 10% THD these things hit 124dB @ 10Hz and 130dB @ 23Hz. If I would have braced them better that 25Hz-40Hz would have been fixed. They were 125 cubic feet each with a 12" port 12" long for a 13.4Hz tuning, 2 IB3s per tower.





Here is the new build:

Krypto, I don't know how I missed this thread but "WOW". I just read all 21 pages and I am amazed with your build and everything you have done in your HT room. Those boxes are huuuuuge! It seems you have had a lot of fun destroying your house. This is a hobby for champions, go big or go home I say. Also, it looks like you have an awesome GF/wife for supporting everything you have done. I know mine would have probably stabbed me in the eye with a rusty screw driver if I had tried to attempt any of this.

Big thumbs up to you for all your experimenting.

The part of the tower I cut down that crashed through the window is still holding up just fine as a window:



Finally added the steps I was talking about way back when

Was going to autocarpet it but this looks better



Black light right over the top for safety and that theater feel

I am sad this never reached 50,000 hits. Can I get just a little love then its retired for good?

To make an honest post, I believe I had the same effect with the doors open vs the doors closed with the towers as well, so that could rule out the bandpass effect on flow vs pressure, however 256 cubic feet inside the listening room could also have had the same bandpass effect.
