Ok bob, get your mind on track here,sheesh.

Anyway i have the wood now for my center channel build. I bought a circle jig for my dremel tool to cut out the holes and recess them.I have a freind that is going to cut my pieces for me tomorrow. Also landed a job with him to install cat 6 and coax and possibly speaker wire throughout a 1800 sq ft house with 600 sq ft apartment over garage that he is building to sell(850,000 range).

In my sparetime i have installed a program called REW (room eq wizrd. I use this to measure the impedance curves of my drivers so i can design my cross over. I will be using the tweet from my vp 100 which i disassembled today.I was going to use one of the 5.25 drivers as well but an Interesting thing i found was the vp100 uses 2 5.25 drivers that measure 10 ohm's dc resistance in paralell to give nominal 5 ohms. Im having some trouble getting a impedance curve on the tweet but im sure it will get sorted out.I was going to build my cross over but decided on a dayton premade one that i may canabalize if it doesn,t measure well. I have a behringer UCA 222 usb sound card along with a behringer ECM 8000 electret mic tha i will use to measure the frequency response once its is built.Just need to buy a spl meter but that will have to wait for a bit. I will be using a external cross over until i get it where i want it,and make it small enough to fit through the front driver hole once im happy.

I designed the box using google sketchup which is a cool prog it does all the angles and such for you , soooo no math = yaaay
I will cover the finished product in real wood veneer.Overall dimensions are 40" wide ,11 high in front-8" high in back and 12" deep. I would attach a sketchup file but i cant seem to figure out how .It will have to rear facing ports 2 inches in diameter which i will make adjustable or pluggable depending what works. Well thats about it for now,will post pics when i get the pieces cut.

You have n SPL meter, REW and that mic act as an SPL meter, no need to buy anything else.

Are you planning on using just the Axiom 5.25" drivers in that size of box? I don't believe you are but I thought I would ask. With that size of box you are well on your way to building your own VP160 (pretty much the same volume) with 2 6.5" drivers you buy from Parts Express to go with one of the 5.25 Axiom mids.

You should call Axiom and see if they can supply you with the impedance curve for the tweeter.

Yes that is what my calculations told me. I only have a certain amount of room between my tv and the shelf so that is why i am building my own. Will be a fun project but probly no cheaper . I will be using 2 x 6.5 , 1 x 5.25, 1 x tweet. I am building 2 actually ,the second one will have 2 x 5.25 . right now i am fussing over the crossover as human dialogue is 300 to 3400 hz roughly and ian crosses the vp 160 at 200 but i am goin to try some higher crossover points .

BTW i have 4 axiom 6.5 drivers and 4 x 5.25 drivers plus my vp 100. the vp100 mids are 10 ohm's dc each so will use them for the second center channel in paralell

Many male voices go well below that 300hz, I am finding the 200hz on the VP160 works very well for me, but play away, no harm in that. I have always wanted to build my own speakers but never allow myself enough time to do it, so I will live vicariously through your project.

I've often wondered if the VP160 or VP180 will improve Ricardo Montalban's voice in The Wrath of Kahn.

Need a higher crossover point for my eyes.

I cut all the wood on sunday but was not happy with how it turned out. My freind is more carpenter than cabinet maker.No worries as i bought a full sheet and only used half of it.My neighbor has a really nice setup,he makes picture frames for a living . Hard to find someone willing to do such a small project.
Right now anyone who is in the wood business is flat out building houses etc.
