DIY La Scala - 1 down - 3 to go!

Recommended Posts

Nice work.

 

What woofer is that?  I see an American flag which is used by Eminence IIRC.  

 

You seem to have plenty of room in the dog house with almost an inch of clearance on either side.  I read that some of Bob Crites' woofers don't fit if only by a smidge.  They must be close, though. 

 

Did you widen the design of the dog house?

Thanks, the woofers are eminence kappa 15c. 
 

I think the clearance looks a little more that it is but yes, I made the motorboard 400mm wide to make sure the woofers fits comfortably.

Looking Good!  I see the autoformers got a little roughed up.  They were fine when I sent them.   I should have mentioned that when I wrapped the common wire on the barrier strips,  I intended them to be on the crossover side.  It will work as you have it, but it will be easier to connect/disconnect the cables from the amp and to the drivers.  

If the amp is still on, as you connect/disconnect a + wire it will be too easy to touch it to the common wire below it.

Quick update..... I had a week off, the weather is too cold to be working in my unheated garage! 🥶🥶

 

Back at it now, the high frequency cabinets are coming together, all glued up today, next step is sanding and finishing then I’ll make the coves....

Top boxes are now pretty much done, just need to make the rear panel and mount the binding posts.

Looking good, very good.

 

Where’d you get the material?

It’s just some leftover material that I had. I used it to re-cover some old Wharfedale speakers on another project. 
 

If I recall it was off eBay for a few pounds.

Quick update on these.... I did a little testing with the drivers and crossover this week, while I am still waiting for the mid horns to arrive, unfortunately, one of the woofers was dead! 🥺

 

School boy error, I bought them used a few months ago and never tested them when I got them..... anyhow, every cloud has a silver lining, I’ve now managed to pick up a pair of K33 (round magnet) drivers from Denmark, so the complete speakers will now be using all original klipsch drivers and horns.

Insulated jumper combs are neater than wire jumpers:

A little more progress today, cut the back panels and fitted the binding posts. I had to make some alterations to the crossover to accommodate the bi-wire binding posts. 
 

Just waiting on the mid-range horns to complete the project!

Its been a short while since I updated here so for anyone that may be following the thread, here is a brief update:

 

I have now installed braces to tame the resonance of the bass cabs and have knocked up a pair of wooden horns to use until the proper ones turn up...... whenever that may be!
