My son is 27 and my daughter is 24. Son graduated magna cum laude and Phi Beta Kappa from college with a degree in neuroscience/premed. He worked at St. Jude hospital in the summers in college and volunteered at a free medical clinic. He just finished four years of medical school and is in his first year of residency at Duke Hospital. Very organized and aware of his surroundings. My daughter graduated with a degree in graphic design, got a job in one month after college (in a very tight market) worked for a large liquor distributor for two years, became the lead designer then just started a new job a month ago with the 175th largest engineering firm in the nation. Supports herself. No problems with drugs or alcohol abuse with either. Neither married yet - I hope they let me pick their mates!!!!!!! I tell them all the time that you can't fix stupid. Think about what is going on in this country and don't believe everything you see in the media. Mighty proud of both of them. Best compliment is they are nice people with tons of friends. Fells good to brag on our kids! Wish I could say some of that about myself!

Front view of horn.

I forgot to mention the front edge trim is 3/8" thick cherry. The color of the bottom piece is lighter because it was sawed but should darken over time and exposure to sunlight. Here's a pic of the EV SM120A horn and ND6X driver.

Guys, thanks for the compliments. Zobsky, I'm using the heatlock glue iron on method with edge clamping overnight. The veneer I'm using is aircraft grade veneer and almost 1/16" thick with wood backing. The side panels are 1 3/8" (1/8" for the inner and outer veneer panels. I haven't used contact cement because we know when it touches it is stuck. However, you probably get a better bond and probably don't need to clamp. Rich, I could be persuaded!! These don't have a home yet. I hooked up the horn and ND6X driver last night crossed at 500hz and was impressed. These things are too heavy to put on the floor right now. Had them on my mobile workbench 3 feet off the concrete floor. Still good solid bass. Here are some pics. The ND6X is impressive. First time I've heard one.

After two thin coats of wipe on poly satin. Another coat tonight.

Thanks Zobsky. For now I'm just going to listen and then might venture on the ported riser. Looks like it adds about 5db on the 31 to 45 hz portion.

Right now I'm running the woofer wire out the bottom since I might do the DJK ported base arrangement.

Update. Got one bass bin built and installed the Eminence 15" woofer which is physically impressive. Here are the WT2 test results and a pic of the woofer on the left next to the K-33. This is a cast frame monster with a 3" vc and huge spider. Sounds good right now sitting on my portable work bench. Tonight I'll connect the EV ND6X driver to the EV SM120A horn and a temporary crossover to see how it sounds. I'll post cabinet pics below. 15 INCH EMINENCE SAMPLE WOOFER 1.docx

I would suggest a 1/3 red 2/3 walnut mix. You can always add more red.

Thanks Mookie. I may try out the "no number" 15" Eminence I referred to above and maybe compare to the 15C which Claude highly endorses.

Here is a pic of the front.

AVGUY, this is one of the very satisfying but sometimes pain in the butt builds. I think the second cabinet will be much easier not that I have figured out the construction order. Big tip is to cut all the parts that share a common dimension at the same time. I've got 3/4" mdf and plywood along with the 1.25" plywood sides so the front edge trimming with solid cherry will be a little different. I'm thinking I'll go with the Kappa 15C woofer and see how those sound with the EV SM120A horns and yet to be decided upon driver (not sure if I'll settle on two or three way). Do you have to components for the build?

UpdIt isn't the 15C but the numbers on it are 11-15 -04 Here are the specs I measured.

Update. Took off the clamps, trimmed the veneer and hand sanded lightly last night. Sprayed a little alcohol on cabinets to show the grain/color. Next step is front edge trimming with solid cherry then some finishing and listening.

Thanks guys, I also just got confirmation from Eminence they are the same mounting pattern. May try them out!

Does anyone know if the hole spacing on the Kappa 15c is the same as the K--33. I know that Bob Crites steel 1526 is the same spacing. Just wondering if the 15C is the same since I've got the screw inserts in place in the motor board. Claude do you know? Thanks.

Update. Got the bass bin put together and veneering now. Pics show the front before the veneer was attached to the sides and top which are now still clamping. Should unclamp tonight. One picture is the back which I veneered as well. I have all the parts cut out for the second bin and should start that later in the week. Can't wait to hear some sound with the K33 and EV SM120A horn and different drivers!

MG, forgot to say thanks!!!!! Thanks for all your effort. Okay everyone which one would you choose based on the graphs????

$330.00 a pair I think?????

MG, help out a fellow that isn't as talented, educated, and smart as you!!! What do the graphs tell you? What order would your rate the four woofers? Thanks.

Not sure if above attachment will open. Try this one

I ran the K-33 through the WT2 and got the attached results. Looks like impedance at 400 hz is 5-6 ohms. K-33 15192 Klipsch 15 inch woofer K-33 15192 Klipsch 15 inch woofer IMPEDANCE GRAPH
