i got a pic of my new..... wo21?
but know not how to,sho u guys?
i can e mail a pic if you can put it up here?

Absolutely!

Just email me. michaelmacwillie@yahoo.ca

Quote from my first girlfriend.. "WOW its so....small!" Yes but it works quite well and I bet that box does too.  ;D

I gotta get around to making a full size one. I need something to fill in the lowest of the lows.

Hey now, watch the accusitions! I only photoshoped on 15 pounds, thank you very much!  ;D

Damn, I hate it when that happens! Get all excited, and it's not drivers

in short,the desighn scaleing works.im not sure as i dont have any kind of meter if its as flat through the range as the origional desighn,but it sounds dry as a bone and a huge improvement sonically over the 15,unfortunately the power handling is not sufficient,the 6.5 were rated at 150wrms but i doubt it,when driven even moderately hard i could hear the drivers giving up?(phut,phut) they are going back and im going to build a scaled for  8 inchers.

so have you decided to keep it?

60nDown <thumbs up> looks good, congrats

Decware fidelity will make you smile

It looks good anyway. You may just need to stick a solid divider in to shrink the internal chamber so you may get a little extra pressure behind the cone, those 6's may not need but a small fraction of a cubic foot chamber size. Possibly 80-100 cubic inches or so. .

You are correct, 60nDown, when the first 90 degrees of signal is being read by the coil, there is a vacuum behind the cone. Therefore the larger the rear chamber the less vacuum, and the smaller the chamber the greater the vacuum. It would be similar to having an air break for the cone, helping slow the foward excurson momentum..adding resistance for distance traversed by cone. With extra vacuum it may assist in reducing the over extention of the cone, and may help prevent the tapping/clapping sound you heard on the lower frequencies.
It also works in the opposite direction once the cone has returned back to starting position (back 90 degrees), in the third 90 degree part of the phase as the cone moves from center in the reverse direction the pressure builds and works in the same way. The w21 is like really cool sealed box where its basic nomenclature is somewhat like having a dual 4th order horn. You may also adjust the spacing between the front of driver and the sidewall, if the internal changes do not help as much as you desired.

Just some thoughts,
Be Well,

The Mini WO is cool

I'm a firm believer in experementation. If you want to dry a smaller rear chamber volume, pop something solid in the rear chambers, about the same size, seal 'er up, and see how it does. If it sounds better, then you can figure out how much volume your solid objects took up, then take that ammount out of the rear chamber. If it sounds like poop, then out it comes.

Fine work 60. Perhaps drivers with a greater xmax along with that ability to handle more power are in order.

Thanks for sharing the pic.

before you scrap this thing, try DD 6.5's (digital designs) youll love them www.ddaudio.com   and their reasonably priced

hm the dds are 100wrms?

http://www.ddaudio.com/dd/caraudio/woofers.asp?series=W6.5

the peerless drivers in there now are 150? but i bet the dds are way better and take more but im not sure ill bother? its a GREAT h.t. sub right now, sometimes when im watching stuff im seriously distracted by the solid accurate bass lines eminateing from behind the tv   if i ever find a 350 wrms 6.5 driver i may re-consider ???

im on a diet

seriously.................................

250 w 6.5 sub...hmmm...ok i got it...call Jes at Digital Designs and have them take one of their 1000 series 8" or 10" moter structures and slap a 6.5 basket on it...

[quote author=denjah2005  link=1100657408/30#31 date=1134269200]60ndown, how did you scaled it! that was so nice! have you tried putting driver on it, and try playing it? how does it sound?
That was a nice photo. [/quote]

i divided all measurements by .65. (i think, it was a while ago) as i am useing 6.5 inch drivers and not 10 inchers.it sounds very good, even tho i made some small mistakes while building it.my full size version is unbelieveable, and built much more accurately.

lol, im 6'1" and 230 lbs? you must be a fat motha.

funny thing is yesterday i dug the wo21 out of the garage and its now fully functiional as my ht sub

and

today i purchased a pair of llder jl 10w3, and im want to build either another wo or a wo32 but for my van, and i have read steve d say somewhere that the wo32 does not work in a car as the wavefront is just to big, but recent discussion here has left me wondering f i did ever read that?

so im prolly gonna build another wo32

theres several of steves designs i havent built, and several i have.

i just love bass, sitting here listening to the wo21 while i type this is reminding me why  love bass,


there is just something so 'special' about an articulate bassline that reaches down really really low..........

i wear a 38 also.

unfortunately for me, my mind wont allow me to stop thinking about it.

its not that i want to, its that i cant stop.

a.d.d.    a.d.h.d. compulsive obsessive ?

call it what you like,  

i have a half dozen finished and working subs in my garage, several amps, and speakers, did i mention the 2000 watt system in my

van?

if i owned a motoercycle, you can bet your last dime there would be some very good quality drivers in my helmet, and my helmet

would be very heavily soundproofed.

maybe even a little sub build out of fibreglass (fireing straight up into the seat?)

given the choice between,

1. diet

or

2.eating whatever  like and geting lots of regular exersise,

if i want to eat something theres no saveing it,

ho-hos and ding dongs live in fear in my town  8-)

i scaled it similar to the difference in percentage of a 10 to a 6.5 inch driver 65%? i dunno it 21 inches wide i think? and half way thru the build i realized id missed some of the lines where the panels should sit by a good bit, so its scaled badly and built badly and it sounds great. im sure if we ran test tones thru it it would be very incaccurate.....or maybe not

my real wo32 was stupid good, did everything perfect. if you have never built a rel wo32 i do that first. with 10" drivers.
