nice initiative. i'm waiting for pics.
btw, did you buy the amp from a guy called Acidburn ?

cut 1 piece at a time and you can build anything. its not brain surgery, get a saw and a tape measure and get  busy.

i made all the angles on my wo using an orbital sander and a wood rasp.

sweet...well thanks.

I'm getting a random orbital sander here soon...I'll post up pics of my WO

Well first off- the mess picture!



Next- a close up to show you all what I was trying to describe with the V cut-


Heres a overview- (sorry for the motion sickness)


Heres a picture of the Dayton's going in the one WO.  It gives you an idea of their build quality.  The speakers also say they are made by eminence if anybody cared.


Heres a shot of the insides getting painted.  I plan to cover most of both the WOs with plastic laminates by Formica, but these are areas deep inside the box I don't want to attempt to cover.


And finally, the cars the WOs will go in!  First up is my car, a 2002 Nissan Sentra.  It will be recieving the WO with the Infinitys in it:


And a 2004 Pontiac Grand Prix.  It gets the Dayton WO:


If you layout the Wicked One correctly, and cut the V pieces like I pictured above- the adjacent angles are the same.  In other words- the angles in the same color circles should be the same no matter what size between 24 and 36 the WO is.  In the 36 x 36 version(If I remember correctly) all the angles are the same.

Yup,
I forgot about the V, but I did it the same way. Made more sense than trying to get the edges to meet in the middle.
The angles aren't exactly the same in the 36" WO. I was talking to Bob about that this weekend and he confirmed that they are slightly different. I think part of that thinking is the V being so sharp, but even without it I think there is a 1 or 2 degree difference in the front, back and middle angles.
Great job. I can't wait to hear the review on the Daytons in this box in a car.

Let us know how it turns out!

Take care,
Robert

Ah yes- the elegance of the WO.  It is just amazing as you start fromt he begining and get to the final steps...  Something about how simplistic the layout and cuts are in relation to the unique design and awesome sound.

I too can't wait for the Daytons- they haven't even seen power yet.  I have a feeling they will rock my world.  Only problem is I will have to try to trade with my friend, and if they sound good I doubt that will happen.

I made four quad-iso-loaded WOs and use them for a band's PA. I really don't notice much difference in the sound, until you start getting into driver power compression. The sound is much "cleaner" with iso-loading when you are pushing them hard- not much difference, otherwise. I also added an outer skin of plywood and some external bracing/skids to beef up the sides a bit. They take quite a beating and raw MDF does not hold up to road use very well, by itself.

I wouldn't alter the chambers, unless you know what you are doing and can confirm benefits through proper testing.

I noticed a slightly lower tuning when I was using a single driver loading and had the magnet structure in the open chamber, compared to keeping the magnet in the sealed chamber. I think the main benefit to having the magnet in the open chamber would be increased cooling ability.

Wow. I noticed a lot more high, midbass frequencies with the "front" of the driver facing the port (I was not using the Decware drivers - they were JBL).  I wasn't concerned as much, because that's what crossovers are for. Just goes to show you that you need to try it all for yourself and choose the results you like best for your application.

yeah but sub displacement is not enough to make a noticeable difference unless the sub has a HUGE magnet and basket

If I build it I will come ... or something like that?

Thanks for reminding me to wipe my chin when I drool, but I'm not sure what is unclear (Alzheimer's, too?). One thing Steve has always tried to make us mindful of is that "Everything" makes a difference. Some differences are worth pursuing and some are not. Switching a driver around is easy and worth trying.



MODDED:
Oh, I think I get what you are saying.
How about, instead of a different "cut off freq" (I'm not sure how that applies to the WO, anyway) a noticeable difference in behavior near the cut off freq?

Well Dirt- I noticed a change, but wether it was a percieved change, or an actual change was to be determined.  I wasn't sure if I was hearing more highs with the magnet in the sealed chamber, or my mind thought I was because I was told thats what happens.

As far as the impact- not only are you changing the size of the sealed chamber you change the size of the compression chamber.  Say your 10 only has .1 cu ft displacement- and say with the magnet in the sealed chamber the volume of the sealed chamber is 1 cu ft, while the compression chamber is also 1 cu ft.  If we move the magnet to reside in the compression chamber, we end up with a sealed chamber of 1.1 cu ft, and a compression chamber of .9 cu ft.  Now the ratio between the two are different, and each chamber is a different volume.  So in this case, even .1 cu ft driver displacement has the potential to change alot in the WO design.

As far as testing goes-  I absolutely love the Dayton WO.  It blows my mind.  The Infinity WO seems to dig a little deeper, and the Daytons are much more efficient (especially in the upper limits of their acoustical range.)

The dayton abolutely needs an XO- and a steep one at that for me.  I really dig a slightly odd shaped curve for now- the results of mismatched XO frequencies on the AMP and HU.  I have the HU at 125hz and the amp at 80 hz.  Results in a 12db rolloff from 80 hz up to 125 hz, where the slopes combine for steeper rolloff of 24db.  The Daytons end up being highly authoritive in the lowest frequencies, yet punchy and hard hitting in the upper range where the kick drum is.  Listening to heavey metal gives you an idea of what sub speed is all about- you are actually able to hear individual slams of kick drums when drummers are going to town rather then the boring drone poor ported designs offer.

I could really type for awhile about how they make all my music sound better- and its amazing how many rattles went away when I changed from the Infinitys in a sealed (albiet poorly sealed) enclosure to the Daytons in the WO.  Its a night and day difference with the WO doing everything the Sealed enclosure dreamed about when it sleeps at night.
