  1. This is an updated post now that the bass bins are done. I just completed a pair of La Scalas clones and bass bins. Although I am not completely satisfied with the finish I chose, the La Scalas do sound AMAZING, and that is what counts. I may re-do them next summer. Project was about a month from start of research to plugging them in. I wish I had researched staining Baltic Birch before doing it. For those interested in the particulars: Mid-range horn is the Eliptrac 400 and and the tweeter horn is the Eliptract HF - I modified the motorboard and the speaker sides 5" taller to accomodate the Eliptrac 400. The openings in the motorboards were cut with a CNC router for exact fits. I left the horns natural MDF and then stained them. I deliberately left traces of the rings in the Eliptrac 400 as I like the look. The construction is all 3/4" Baltic Birch. I may go back and include the braces if the resonance issue I have read about becomes a problem. The drives and crossovers are all Bob Crites. Tweeter is the CT 120. Mid-range is the A-55G mounted to the Eliptrac 400 with an PS 50 aluminum adapter. Woofer is the CW 1526 (Stamped frame). The crossover is the AL3. As to the bass bins, the grills in the front of the tubes pop in and out although I have to admit I cannot hear any difference. I cut the 4" diameter PVC tubes to a length of 7" in accordance with comments I reviewed in the forums. Yes, I know that the bass bins are narrower than the speakers. Some idiot (me) cut the top and bottom of the bins from the dimensions of the Chamber Bottom (22 1/4" x 23 3/4") based on the attached plans. They should have been 23 3/ 4" by 23 3/4". I do have enough wood to make another pair and may do that next summer when I refinish the speakers. I did catch that the lid for the bass bin in the plans is backwards. Mine also have internal bracing, and corner reinforcements, and supports I made for the 4" tubes. I am presently using an Yamaha RX A3070 with the pre-outs for the La Scala clones routed through a completely restored and refurbished Phase Linear 400 Series Two. The system has to do double duty between an Audio/Video system and a stereo.
  2. And La Scala inspired clones it shall be!
  3. Yeah, not happy with the stain. Thought I had researched everything about building these but must have missed posts on not staining Baltic Birch. Maybe re-do them next year. Just finished the bass reflex bins. Did 7" tubes. Noticeable difference. Probably cannot call them La Scalas, just didn't know what to call the to post to the forum.
  4. I will post some additional pictures. The finish is Dark Walnut oil stain by Watco. Probably would not use it again. The Eliptracs are MDF and absorbed stain differently than the Birch. My family room is big with 9 foot ceilings. They are 39 1/2 " tall. I am working on the reflex bass bins for them.
  5. I apologize in advance if this is the wrong place for this. I just completed a pair of La Scalas from the plans provided on this website. A sincere thanks to everyone who made this possible, including Dave Harris for his amazing Eliptracs. Although I am not completely satisfied with the finish I chose, the La Scalas do sound AMAZING, and that is what counts. For those interested in the particulars: Eliptrac 400 and Eliptract HF - I modified the motorboard and the sides 5" to accomodate the Eliptrac 400. The openings in the motorboards were cut with a CNC router for exact fits. I left the horns natural MDF and then stained them. I deliberately left traces of the rings in the Eliptract 400 as I like the look. The construction is all 3/4" Baltic Birch.

The system has to do double duty between an Audio/Video system and a stereo. Anyway, thanks again! ..
  6. I hope that this is the right place for this as I am new here. I am embarking on a La Scala DIY build. I have been through everything relevant I can find (I think) as to constructing these, but I still have a couple of questions. I am going to go with the Crites 15" woofer and I have found the dimensional changes needed to accommodate it without cutting the woofer. I am going to use 3/4" Cherry plywood veneer as you cannot find 1" anywhere I live (Spokane, WA). Will probably get the braces I have seen for sale. It looks like the hole in the floor of the doghouse is there for access to the woofer, if needed. My questions are: 1. Is the doghouse removeable from the cabinet itself to gain access to the woofer or am I missing something? 2. The majority of plans indicate that the woofer is attached with T-Nuts to the motorboard, yet some pictures I have seen show it mounted to a separate board, or even to a round ring that stands off from the motorboard. Is that just personal preference? 3. Where do you actually obtain the midrange and tweeter horns? There is a lot of discussion about what people have used, but little on where you purchase them. I found the site that sells the various crossover networks. I really appreciate any information. Thanks in advance.
