Silly's First Project

[Sillyboy]

My first project will be Zaph's project #14 (Audax Mini) -- http://www.zaphaudio.com/audio-speaker14.html

Thanks to those that chimed in on my first thread (considering the HiVi junior project, and on the thread were I attempt to understand proper enclosure volumes

I became fairly married to the idea of 2-way with a 4" woofer, then found the Audax drivers on sale at Madisound, so Zaph's 14 seems like a great fit. I plan to build a sealed enclosure, so my next project can be a sub

I am excited to get this show on the road!

We are excited for you and are anxious to see the results. Please keep us abreast of your progress and post photos if you can.

Good luck!

Hi, good to see that there's more and more exited guy from audio stuff, please keep updating with pics.

Hi,

I'll just point out that #14 is a good choice as long as you can actively
cross them them over to a sub, i.e. you have a home theatre amplifier,
and you can set the speakers to "small" in the set up options.

Also note #14 has full BSC, a reduced BSC option is not detailed.
This means they will need to be moved away from the rear wall.

/sreten.

No prob on the active crossover. I have a (really really horrible) sub hooked up in this configuration already. I intend a "real" sub to be my next project.

The BSC situation is almost so hopeless as to not bother discussing it.

The left speaker has a ton of flexibility... from say 6" from wall, out to 3 feet. The right speaker... hopeless. The speaker will basically centered (vertically) on a half wall... such that half the speaker is about the halfwall (where the "next" wall is about 7 feet away)... and the bottom half of the speaker will be too close to the wall, probably 6". Yes, nightmare.

However, it is also what I have going on already w/ the current crappy speakers, so... still an improvement. And secretly, I hope that some day these end up just being my computer speakers

Thanks for double checking these points w/ me sreten. You rock.

I hope to buy wood for the enclosures today. I have already been messing around w/ the router, trying to figure out how to counter-sink the drivers... it's not pretty

Mark's page on this same project (http://www.mhennessy.f9.co.uk/audax/experiments.htm) is really helpful, but my router has a guard in the way where some of the holes in the jig would go. Think I can just make a thicker jig and basically cut blind, trusting the jig... should be fun

[Sillyboy]

Doh! Madisound doesn't have the AP100Z0's anymore!

I was much happier at $20/each from Madisound... but parts express does have them for $28.75/each.

Oh well.

As mentioned two posts back, I was worried about how to make cuts for the flush mount. Well, I was able to play with it tonight, and I am pretty sure I have a system that will work for me

It's all about a nail that I used bolt cutters on...

I attached a piece of particle board to the bottom of my router, and plunged the router on through. I measured from the of the plunged hole (plus or minus ) out 1" and drilled a hole that just fit my nail. 1" + half of the 3/4" bit ... in radius.. makes for 2.75" diameter circle, which I believe is the size of the tweeter baffle (is that what they call the plastic piece that on the speaker that I am counter sinking?).

So, then I drill a hole where the center of the tweeter will go (in this case just a random spot on my scrap wood)... again the size of my nail (and using some tape on the drill bit to make sure I don't go too far). And that's about it. Drop the piece of nail in the hole, line it up w/ the hold on the router jig... set the depth... and spin away!

Seemed to work! Test shot attached that indeed turned out 2.75". I attached a pic of my test cut if you wanna see

I used the same principle for making my router jig. I used a piece of 1/8" plexiglass (makes it easier to see your work) and scribed reference lines on the plastic for measurements. I drilled three holes for the router base and countersunk the holes. It spins around flat and will cut a hole from 1 3/4" to 30". It's alot cheaper than the prefab hole jigs and combines the small and large size jigs into one,

I would have preferred a thinner pierce of wood for my base, and plexiglass does sound awesome! However, I wasn't sure how to deal w/ the existing router base (the metal I actually screwed my jig onto). It's a complete circle, about 3/4" inch wide (20'ish mm for non-us ) ... and I need to cut some distances that would fall right in its way.

Wasn't sure how to handle that, so I went w/ the think wood, requiring me to work blind.
