So far, the votes seem to be in favor of building the Classics. I would definitely be building these in the vertical configuration and I have mocked up their bulk and placement in the room already. The room layout shows the vertical configuratin with the 24"x30" footprint. The 41" height would place the Cobreflex and tweeter at ideal heights for listening. The size doesn't really bother me, as I already have a couple or three different and smaller speaker pairs stacked in there already. They would go and the classics would take their place. But what about separation? This may be a somewhat foolish question, as the Cobreflex and tweeter would be in about the same location as my current set of speakers. I guess the overall bulk of the Classics is what's throwing me off. It might just be a psychological thing visually. OK, so I buy a pair of Cobreflex horns, mount my T-30 drivers on them, rebuild my N-3 crossovers with better capacitors and go from there. What't the best material? Seven-ply birch plywood like they used back in the 50's and 60's or should I spring for 13-ply Baltic Birch? There's also that 11-ply stuff that you can get at Home Depot and Lowes, but he qulaity seems highly variable. I'm thinking MDF will change the overall sound, but could be wrong. Plus, in that size enclosure we're talking some serious weight! Should I be posting these questions on the other thread? Thanks again everyone, keep it coming! Chris

Hello all. I'm new to this forum and hope to get some advice. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> So I hope you don't mind a longish initial post to give all the relevant background. Ive been planning on building a pair of new speakers for quite some time now. The problem I have is fairly common: I have a small listening room at roughly 10x12 with 9 ceilings. Not only that, but it has to do common duty as my home office due to WAF issues so its kind of crowded with the work table and a rather large freestanding laser printer. Lately, I became enamored with the idea of building a pair of University classics. It all started when I came across this thread on the forum: http://forums.klipsch.com/forums/1/657097/ShowPost.aspx One of the reasons it caught my attention is that somehow over the last couple of years I have managed to accumulate a fair quantity of University drivers, including: Four C15W Woofers Two H600 Horns with T-30 drivers Four H206 Tweeters Two N-3 Crossovers Zero Cobreflex Horns (so far at least, but theyre on eBay all the time) plus some others: Two 312 Model 200 Co-axes Two C8W Woofers Two C8M Midranges Two T202 Sphericon Tweeters All of these last were NOS, but probably don't have a bearing on this post. Anyway, back to the point of all this. Reality set in when I plotted the measurements of the Classics against the floorplan of my office/listening room, which looks like this: Due to the small size of the room, whats in there already, and the large size of the Classics, they end up being awfully close together. How bad is this? Should I still build them, or build something with a smaller form factor like La Scala clones? I also would like to get the best, cleanest bass that I can. Id really like to like try my hand at building some folded horns and Id also like to use the University drivers I have on hand. I have both of Abe Cohen's speaker books had looked at the different plans, but all of the folded horn speakers are pretty bulky. I dont mind going to a higher aspect folded horn if it narrows the width of the cabinet. Any ideas? I also realize that the drivers I have may not be suitable for use in a La Scala clone, or other folded horn designs for that matter. If necessary, Ill sell them to buy what I really need. Oh yes, I left out an important detail. Right now my main system is a restored and upgraded Fisher 800c, but I have a series of projects currently in the works including a pair of 300B monoblocks and a 45 SET amp. So I would like to have something thats pretty high efficiency, especially for the 45s, which I cant wait to assemble. So bottom line, Im open to any and all ideas and will respond happily and gratefully. Thanks in advance! Chris
