4-18" Fi Q HT's Project (Spring 13')

post #1 of 3
Thread Starter 
I have spoken to many of you before this purchase as to my goals and I appreciate all of your input. My drivers arrived today. 4-18" Fi Q HT's S2. I have a couple other projects that need completed before I begin on this one pushing this to Spring. However I wanted to share my pictures and ideas.









Next to a 12" AA Arsenal



Enclosure: I plan on 4 individual slot ported enclosures under the tv. The enclosures will be 20"(W)x 28"(H)x 25"(D) with a countersunk double baffle. Internal cf before port and driver displacement is 6.45cf. I am still deciding on the tune. I am a little stuck there and need to decide between 17Hz and 20 Hz. I am leaning toward the 20 Hz tune as I listen to a lot of music in comparison to movies. The length of the port tuned to 20Hz is 2x 9"(W)x 3"(H)x 52.2"(L) ~.5cf. The driver displacement is .24cf. Net after port and driver displacement would be 5.71cf. I am not sure if I am going to use dowels or scrap MDF for bracing so I will refrain from trying to estimate the volume they will use. This is as large (W) as I can go and still have room for my mains, which are yet another project in my book. I can increase the height to 30" and increase the gross internal cf to 6.63cf but I don't think there will be any discernible increase in output and would cause the tops of the enclosures to block too much of the windows. I was given clearance to do so, however I don't want to push my luck. smile.gif

Power: As soon as my project funds are replenished I plan on buying the iNuke6000DSP. I chose this option due to the built in DSP and power output. I will be ordering and replacing the stock fans at that time.

AVR: Yamaha RX-V2400. I have considered upgrading this unit, but the budget just isn't there this year. Until then, this will be the AVR.

Sources: PS3 for movies (both DVD and BR) and games. My laptop to stream Pandora and my mp3 collection. and finally the Direct TV HD receiver.

If anything looks off, please feel free to give me input. After learning how to successfully input driver data into WinISD, the program no longer works. I have to force close it when I try to use it. I think I may invest some time into trying another method for modeling. Scott Simonian suggested Unibox. I need to get Excel first. I had it on an older laptop I used in school but it has recently died.

I was thinking the same thing. smile.gif I wish I had one of my older 12" AA Havoc's to put in the picture too but I sold it a few weeks ago. I am really looking forward to building these. I know this is an average everyday build for the folks here, but it is as big as I have ever attempted in a house.
