WOw!!!! wow!!!!! this thing is going to be hella sick with 2 idmax!!! I've always been looking at those decaware plans but just never found the funds to build one. Really want hear your review of this when done.

lots of people have tried a wicked one with 12" subs, with varied results, changing anything about the design changes performance.

if you want to try steve deckerts ultimo sub, build a wo32, truely amazing.

[60ndown]

That is a WO32 from Decwares website, I only have a cardboard mock-up at this point.

There will be pics, once Pete and myself get going on this!!

Stay tuned ;)

oops reading pwns me, in that case driver ts params are very important, too much x max and drivers are gonna touch the outer panel :o

"An obvious difference between the WO32 flare design and a more conventional horn is that the taper shrinks to a point. Sometimes called a tapered pipe. The woofer is loaded on the sidewall of the taper firing directly into the adjacent surface less than 1 inch away. This technique over-dampens the woofer resulting in a flatter impedance curve, excellent power handling, and better linearity within its operating range. The typical air space between the cone and throat has been reduced dramatically. This creates a direct linear relationship between the air in the horn flare and the woofer driving it."

your using idmax 12s in a wo32?

my wo32 got very loud and VERY low with $60 dayton mrk 2 10s and 200 watts.but i built it exactly to deckert spek.

if your lucky, and your modifications dont destroy all deckerts design objectives, that subwoofer will shake everything off the walls in that wood shop , while sounding beautiful.

(my wo32 was easily the best sub ive ever heard, it played every frequency from 80-20 with EXACTLY the same volume, no roll off at all as the notes got lower, no way to understand that until you hear it)

Keep up the great work and progress pictures. It will be a masterpiece when its finally done. I wish I had the skills and tools to do some good woodworking of my own.

[cheesehead]

Pete has some serious understanding in him, He does things that bring a smile to my heart :D !

Early on in our relationship, his technical know how just blew me away.

At this point he just calmly exudes utter mastery of the concepts i throw at him and then does his thing !

I'll explain something and watch his eyes to see if he thinks it's doable or not worth pursuing, he went to get the solid birch [ the guy knew where it was {a small shop}and Pete and him moved several piles before he produced exactly what Pete was after}, It's this attention to an image in his mind"That Pete is trying to create, that was so incredible to me.D

Sounds like you're describing an artist!;) I dabble in woodworking but in no means am I on or even close to the level of mastery that Pete is. I truly appreciate fine woodworking craftsmanship. Great Job and Enjoy!

[a$$hole]

[60ndown]

Cheesehead,

In the photos you will see him eyeing things and trying to decide if it is up to his specs ;)

He reworked mathematically the Deckert WO32 so the sound would flow out of the mouth. :D

5 separate possibilties for one angle as it transitioned to the next area!

In the photos he puts two layers of tape on the board so the 1,000ths of an inch will come off of the right surface ;)

Craftsman Extrordinare, Manifique !! :cool:

so where did petes math tell him deckerts design made the sound come out?

as far as i know, you cant just change a horn design that works, and the wo32 the way it was designed works, if you change anything you risk failure, you might be building a very heavy very expensive waste of time.

Today Pete and I worked on the sub change out and he sanded and stained some more pieces.

The subs have a cleaner sound and blend better, to quote Pete : "Those are doing what they should".

Listened to Ladies with Voices and a couple of other very well made CDs :D

Once Pete has got the stain on , then comes the sealer [shellac ], the red mahogony color of the [Gunstock = color they call their stain ] stain will jump out at you.

Pete is doing this project with a "Hand Finish", no power tools will be used :)

His goals are to make this the best one we have done !

Pete had to pick up a female x 2 connector[ to a single male connector ]to connect the 5150 plate amp up to the CD player.

The guy at RadioShack told him we couldn't do what we've been doing with what we have... (Basically, there ain't no way it can be hooked together the way we connected it},[ Radioshack employee: "Sir that won't work", Pete: OK :p ].

At that same store some months ago , I told an employee what I would like, and what I was going to do, He said: I don't have what you need...I walked over and picked out what I had asked for, watched him as he explained why it would not work [ paid him,and died laughing all the way home ].

Promptly connected it, {Nothing but smooth sailing},and never looked back.

[a$$hole]

Temporary set back in Michigan , the shellac clouded while Pete was applying it [ too much moisture in the air ].[ alcohol absorbs moisture ];)

Think hangover for woodwork :p :p :p

I maxxed the crossover [100 hz and down ]on the subwoofers because I liked the song ;) whole lotta shakin goin on [ everything was vibrating at it's Fs {natural frequency}, windows most notably :D

never turned the gain past halfway!

Pete is going to drop the wires out of the bottom board right beneath the subwoofers on both sides [ cause the box will be raised up with a skirted lower edge{ we will be putting the connectors thru the skirted portion}that will conceal the wires beneath the enclosure.

Even though all the frequencies will not be horn loaded, just having 2 drivers coupling their output will be something to hear !![ above the passband and below the passband that is hornloaded ]or louder due to efficiently coupling the air to the drivers ;) .

[a$$hole]

Desired effect

quote}
A horn speaker is a speaker system using a "horn" to match the driver cone to the air. The horn itself does not amplify, but rather improves the coupling between the speaker driver and the air. Properly designed horns have the effect of making the speaker cone transfer more of the electrical energy in the voice coil into the air. The driver in effect appears to have a large surface area.
end quote};)

If you think about this for a moment it should make sense to you [ I hope ].

[a$$hole]

Iselected some photos, that I feel give an example of Pete at his finest.

He decided this himself, The reasons are known to him, He decided to make the convergence of these two points with solid birch [ WHY ? ].:D

[a$$hole]

Wondered what you all think about not gluing the boards in place ?

Pete has made mirror imaged top and bottom wood plates that will hold in place the vertical panels by the grooves he cut in the top & bottom wood.

The subwoofers had to be moved from the end of the boards to the center of the boards.

The mounting board or baffle had to be lengthened too.

The whole box has been raised 2 inches to account for grooves the boards will rest in on the top and bottom.

Predictions anyone ? :)

[a$$hole]

Hoping to put some more photos up tomorrow, we'll see :)

[thylantyr]

Bass horns can get pretty crazy in SPL if designed so and
the walls of the horn will be subject to torture and they
will vibrate. The last bass horn experiment I did was using
an Eminence Omega 12" midbass driver driven by 600w
amp and the 3/4" walls weren't enough, 1.5" thick minimum. lol

How your box performs will depend on the torture factor.
I don't understand the 'didn't glue' issue.

The baffle will run the full length and will be doubled up.

The top and bottom will hold the wood securely [ grooves, recesses ].

Picture is worth a thousand words, I hope.:)

[cheesehead]

A$$hole

What are you not gluing? The top and bottom panels? I understand the recesses in the panels to "lock" in the sides but what is Pete's reasoning for not wanting to glue them? Is it in case you need to disassemble the box? Or does Pete feel it is just unnecessary? Either way the work is fantastic!:)

Pete is truly a craftsman!

On a different note............ You seem like you enjoy quality crafted woodwork. Have you ever been to the Grand Rapids Public Museum? I'm not sure if you know this or not but......Grand Rapids was once dubbed the "furniture city" back in the day. In the museum is a section dedicated to the furniture industry in G.R. If you would like to see some amazing craftsmanship I would recommend a road trip to check it out. I think it's worth the drive. My family refuses to go there with me anymore because I will take 1-2 hours just admiring the fine detail that was put into furniture back then. Now days everything is massed produced with particle board and veneer.:( Anyways check it out sometime if you haven't already!

Nice work Pete! There's not many people left that have the skills to do work like Pete's!:)

The shellac really brings out the life in the wood :D

Recap

1] wellnuts to help isolate the vibration from driver to cabinet

2] feet to decouple the enclosure from the floor

Hoped for result, just the driver cone coupling to the air !

:)

[a$$hole]

My DD's come with 10 guage wires so I've decided to run 8 gauge wire to these , wired in series 8 ohms.{at least til they get a few hours of play time}

Thinking about some additional sections of horn for playing lower frequencies {horn loaded}[kinda like adding ductwork to a furnace so as to channel the flow]

[a$$hole]

Thank You , for Pete :)

My EBP on these drivers is 51.6 :)

quote}
On the other hand, using Leach's math, predicted optimum drivers for bass horns have EBP's of around 50 or lower. I have used such drivers in a subwoofer horn, and the subjective results are excellent. The horn works pretty much as predicted by Leach's model.
end quote}

quote}

I attach importance to these factors in designing any speakers, but specifically horns:

Smoothness of frequency response
Smoothness of power response (response at all angles)
Tonal balance (how flat the frequency response is)
Low distortion at the expected maximum playback level
High efficiency (to reduce power compression for a given playback level)
Time alignment (usually not a big deal for cones, but worth mentioning with large multiway horn systems)
