  1. Don't intend to hijack this thread, but are there any benefits to disconnecting the zener diodes from my LaScala wuth AA networks (rebuilt about 12 years ago with Sonicaps)? I currently have the SMahl with DE120, so I understand that the diodes aren't necessary. If so, do I just remove one nut and let it hang as has been suggested in this thread? Thanks
  2. I'm not sure most LaScala owners would consider the bass as being "boxy" sounding, though I think I get what your friend was referring to. It seems that once my ears had been attuned to the resonance peak at 140hz, I couldn't not hear it. I have yet to measure the Q-Pies in my studio, but to my ears there doesn't appear to be any noticeable bass peaks like before.
  3. So I got my first good listening session in. Man, this really transforms my system to whole new level never yet experienced. New bass textures are really apparent and quite stunning really. I listened to some CDs that I've had for a couple of decades ranging from glitch electronic Pan American, to Hector Zazou, to Neil Young, to Brokeback, which is wonderful foray into acoustic stand up bass. Everything, and I mean everything that I've played has gained so much foundational impact that I believe I've reached my immediate audio goals... and for the price of lumber, screws, glue and paint. Everything cost me less than $400CDN, which has proven to be the best money I've spent since buying my LaScalas over 12 years ago for $800, which still represents my best bang for the buck purchase yet! Guys, this is a no brainer for whoever can afford the space and time to build them!
  4. Yes, I added three braces per channel, they are 7" wide with 3 1/2" corner cutout, like the woofer mount piece. I used even more of the pre ripped lumber so there is even less wasted wood. I think before adding any subwoofers to the fray, I'll need to learn how to take and interpret measurements. On this front I've borrowed a Umik -1 from a friend. Now I'll need to make sure that my Mac Os will support REW. I know that getting Sketchup to work on my computer was quite a task, I had to find a much older version. I'll find the appropriate REW measurement FAQ thread with questions as they arise. I'll take your advice, once again, and appreciate the Q-Pies as is for a while before considering my next move. BTW, sub placement isn't an issue for me, I've got the luxury of total creative freedom in my space, it being an artist's studio after all!
  5. Well, I didn't update soon, nor often... too busy making sawdust and getting these things glued and screwed, I didn't even take any "build" pictures. I got them finished up last night and convinced my wife to help me shlep them into the studio. Someone earlier in this thread mentioned being surprised by the size of these horns once finished. AMEN to that!!! I knew going in they would be big, but once assembled and in place they make the LaScalas look like "normal" floorstanders. Claude had me speak into them before adding the drivers to see just how much it acoustically amplifies the male voice, boy does it ever. The kids were entertained listening to me make all manner of guttural noises into them. I followed Claude and MustangGuy's dimensions exactly, everything fit just so nicely and the build was a real pleasure to assemble. It was well past midnight by the time I installed the K-33 drivers and got everything hooked up, so my listening session was short and sweet. Here are my first impressions. - I welcome the added 17" height to the LaScala's tweeters and squawker. I'm more often than not sitting in a drafting chair, which is quite a lot higher than a regular couch and the tweeters are essentially ear height. Having said that, in my listening chair which is lower, is also very pleasing. - The added bass isn't subtle, and it sounds much better than my previous ported bass bin mods. I tried a couple of bass heavy tracks and the kick drum/double kick drum has more immediacy and slam. I also heard some very intricate bass guitar lines that are more palpable and clearly dig lower. The 140-160hz resonance of the LaScala seems to be a thing of the past, though I have no way of measuring with a mic. I ran some test tones and where I previously had an important hump in the 140-160hz range, it is now significantly and audibly reduced. I will live with my system as is for now, it being for 2 channel music only. Subwoofers are definitely on my list of things to build sometime in the future. Building these was a great intro to cabinet building and I'm confident I can pull a subwoofer build with ease. I'm more than satisfied with the results so far! A big shout out to Claude. This Q-Pie is such an elegant design solution for anyone with the room and ambition to get the most out of a bass bin, thanks Claude! Daniel
  6. Had a good day, between being a stay at home father with three kids under 11 and building a set of Q-Pies. I ended up improvising a vertical crosscut jig for the table saw, which permitted me to get the acute angle cut I was enquiring about in my previous post. As far as I can tell, the fit will be almost perfect even if Claude has reassured me that a perfect fit isn't that critical to the overall performance. I also fit and assembled the first three pieces (the large L and reflector). I made sure to keep it nice and square, glued and screwed every 4". I hope to work on this again tomorrow, I should be able to scrape a couple of hours away from the kids! Question: should I build both channels at the same time or continue with the first until it's done?
  7. Alright, I've started building a set of Quarter Pies with 3/4" BB. Been on the fence for over 5 years and now have the room and time to make it happen! It's time to see what getting a "full horn" down to 50 Hz is all about. I'll be using the K-33 from my LaScalas and setting them on top of the Q-Pies, just as Claude has been suggesting for many many years. I wonder how many, if any LaScala owners have followed his suggestion? I've cut the main pieces and pre drilled/counter sunk all the holes on #1 and #2, it has been very straightforward so far. I haven't cut the flare pieces #7 and #8. The 11 deg angle will be easy, though I'm not sure how to cut the proper angle for where the flare pieces meet the sides. Bill Fitzmaurices jig plans include an acute angle jig, which will do the trick. Is there a simpler solution for those two cuts? Will be updating soon and often. Daniel
  8. Had not put much thought into it, the contrast within the bass bin would surely be very beautiful.
  9. I agree that it looks really swell with the badges in the corners. The TT is a pristine Lenco L70 with Shure M3D cartridge, may not be the last word in "HIFI" but it sure does boogie!
  10. Yeah, I deleted it to reinsert a different picture.
  11. I really suck at uploading pictures it seems, so my 5 picture tutorial will have to wait. Here is the final version.
  12. So I'm the type of guy who enjoys not only listening to, but also looking at his system. I've had my 1979 LaScalas for about 12 years now and have recently decided to modify them following much of the present member's examples: Dave's fantastic SMAHL tweeter lens + DE120, A55G drivers from Crites as well as his crossover kit. I had built the bass reflex mod for a previous listening room, and though I liked what it brought sonically I couldn't get over the looks of it, just too ugly IMO. After listening to them with the mod in my new listening room/artist's studio for a few months, I decided to remove the boxes and try the LaScala au naturel. With the corner loading and various room treatments and not lacking any bass impact, I decided to leave them as is... until I embark on the Q-Pies :) My only remaining aesthetic issue was with the SMAHL tweeter's looks. As beautiful as the lens is, like a jewel frankly, it is simply too anachronistic for my liking. This led me to wanting to install some grills to dress them up. I've seen several examples of custom and factory grills but ultimately decided to apply what I learnt in art school to build my own examples based on how I stretch a canvas. I used 1/4" HDF, cut to 11 1/2" x 23 3/4" as a base. I traced the template on the first and drilled pilot holes through both panels simultaneously. My skill saw made quick work of connecting the pilot holes to cut the window. I then used 11/16" quarter dowels to create the raised sides, like a canvas. I glued and clamped the dowels and let it cure before painting the whole thing matte black. Once that dried, I stretched the speaker fabric, Fender modern style from :https://nextgenguitars.ca/products/grill-cloth-fender-style-modern-blackface-by-yard-36-wide.html. The grill is affixed with good quality velcro as is the pie Klipsch logo (have yet to decide exactly where I want to place them, they used to be in the middle below the squawker horn). After listening for an evening I am certain that the cloth is reasonably, perhaps even totally, transparent. I love the looks and offer some pictures should anyone be inspired to replicate my solution.
  13. These look really great! Any chance you could elaborate on the assembly of these grills? I'd like to make something essentially identical for my 1979 black LaScalas and was looking for inspiration, when I found this thread. Any help would be much appreciated!
