How many sheets of Plywood did this take? And I notice that most people put veneer on. Is Veneer necessary?
I'm asking because veneer looks like an added expense which if you use a higher grade plywood that veneer could be eliminated. Are there too many screws that hold the panels together that Veneering would be the only way to eliminate those ugly screws? Could biscuit joinery be used on assembly versus screws?
I am assuming the bass bin is of a vented design, so there is not a lot of pressure inside the cab.

I have a pile of tongue and groove hardwood flooring left over from jobs; Brazilian cherry, oak (red and white select and quartersawn/rift cut). I would imagine this stuff would make some serious cabs for a project like this. It's a lot more expensive then plywood but I am wondering if there would be an added benefit of hardwood enclosures in terms of cab stability and added weight for dampening?

PWK experimented with all kinds of wood and always came back to plywood, it sounded the best, he said...
 
Not to mention the insane finishing capabilities. It could all be done glued and if desired, biscuit or doweling for the corner meets. You also can use a fancy router bit if you wanted to add something like a crownmolding type cosmetic feature

EDIT Ok Lee, I guess wood is wood whatever the form LOL

Check.... Lol I think I got it all ready! I hope lol

ya I think when I finally build some they will be unfinished also. I really don't care about looks. If it sounds right that's all that matters to me personally !! But DIY really opens up the options for appearance . You can leave them naked or get crazy and really do them up. Maybe ill paint my horns green...

The bass bin IS NOT vented and MUST BE airtight....I have plain old plywood---unfinished--- cabs....

So the design you are using Lee is a Acoustic Suspension Sealed Bass Bin cabinet and not a true Klipschhorn?
I understand now why the need for so much more power for the bottom woofer cabinet.

Definition of the Klipschorn:
"Two rectangular horn lenses coupled to compression drivers handle the midrange and treble, while a 15” cone woofer is mounted in a folded bass bin compartment below. The folds OPEN AT THE REAR of the horn cabinet structure, utilizing the room walls and floor as continuations of horn structure, thereby increasing the effective length and size of the horn and affording greater bass extension."

Whoever built these cabinets used a small nail gun and good glue... No screws.. Very very few that is... And when I rebuilt the top horn cabinets I only used a small nail gun and glue... Veneer is not necessary.. I did it just for looks. The other speakers I have, and Sub Have the same Veneer on them... These were built using a finished plywood But over the years had been scratched up pretty good ! And yes !!! LOTS OF PRESSURE INSIDE THE CABINET !
 
Mike. The back of the woofs are sealed.the fronts obviously are not. That's common to all k's and k-klones...
 
I will take some pic's of the rear... and the back of the horn cabinets... And the woofer door !

Yeah I understand what you are saying. Thats typical of any acoustic suspension speaker. A sealed cabinet.
But I always thought Paul Klipsch horn was open at the back and used the corner to extend the bass horn to extend
the lower freq. That why the placement in the corner..........hence corner horn. They are not sealed per say.
Here is a cut-a-way photo.

Edit: Ok I think I get the whole deal now. It is sealed if comparing it to a bass reflex cabinet. NO PORT.
The front of the woofer extends to the sides, and the back being sealed.
What a great design. No wonder its a classic. And it looks like a real pain in the ass to build per the
cut-a-way- photo. Now I understand why they cost so much then. and now.

Sorry guys, My thick head.
Nice job Kevin. They look great man.

Looks complex with many internal dividers!
 
I like these....

"A 25 watt 10 inch pioneer woofer shook items off a neighbors shelf in the house across the street. Distance: 220 feet. It did that with one channel of a 22 watt class A receiver"

"using only a single 12 inch woofer and 80 watts we were able to move the ash trays on 51 tables throughout the facility"

I wonder what the wife would think of two refrigerator sized speakers w/ 300w Vega 12" drivers driven with a WOPL? This looks interesting



 
This takes the cake though and is truly sig worthy :laughing5:

"I really can't begin to describe what happens at that frequency when you hit that SPL, but it's serious. We saw a mouse stagger out of a crack in the concrete floor and die"
