Check out the viewsonic pro8200. I have it in my living room driving an approximately 120" screen and it does it very well for an $800 projector.

I have a '62 without reverb and is 1x12. The thing is pure magic. Someone has to jump on this!

I have a couple of K77 tweeters from my lascalas that I'd be willing to part with. PM me an offer if interested. Matt

Sounds like you are thinking about what is commonly referred to as a "CornScala". If you search the forum, you'll find lots of information on them. I built a pair several years ago, and I'm ecstatic with them. Also see this link: http://www.critesspeakers.com/cornscala.html The key dimensions are: 6.59 cu. ft. internal volume 50 sq. in. port 9 in. port shelf Matt

Yeah, even with the limited time I have comparing, I would recommend it. I need to spend more time tweaking the length and sealing the top chamber to get the most out of the mod. It should be noted that I went with the plywood port just because I had some laying around. PVC seems like it would be super simple and clean. Matt

Ya know - I was wondering the same thing. It works just fine. Are these fluid filled at all? If not, I'm guessing something got spilled on top and happened to go in the front where the tweeter mounts.

Yeah, that's half the fun is trying things out. I'll probably break out the saw to shorten the ports eventually. My (limited) understanding of ports was that it was just the area. I haven't seen a detailed scientific analysis of the port size for this type of mod - but I'm sure it exists. Anybody have a link?

Bruce, I used the same area as 4 inch diameter ports. I went with 10" deep because I saw people using in the range of 7-10", with the thought that I can always cut it down if I need/want. Matt

Hehe, aren't they awesome looking? They are residing in my basement/workshop right now, so probably nothing as far as restoration right away.

Update: I installed the ported covers. No graphs, but a marked improvement in bass - highly recommended mod, especially when it's as easy as it is with my speakers.

Thanks, guys! I picked them up yesterday. They aren't in as bad condition as I thought based on the pics from the seller. Someone took standard LaScalas and turned them into gigging PA speakers. They covered them in carpet and put corner guards on. I have posted some pics in this thread: http://forums.klipsch.com/forums/t/170092.aspx

Ported back cover. The glue is drying now. I can't wait to try these bad boys out and see what a difference it makes!

HF area

I just got a new to me pair of La Scalas yesterday. Of course, I couldn't wait to start messing with them. I'm not sure what year they are, as the previous owner covered them in carpeting, which ruined the ID sticker on the back. They have removable tops, and the doghouse access is in the HF area. I plan on closing in the HF area with a ported panel to help with the bass - see pics.

They will be for the basement. I have a pair of CornScalas I built that are in the living room. Ultimately, the exterior condition isn't terribly important to me. So, let me rephrase my original question: Is $500 a good value for a pair of any type of La Scalas that are rough exterior but function fine?

Interesting. Was carpeted ever an option? If not, someone must have done it themselves. Thanks for the info - it is a bit of a drive to check these out so I wanted to see if it was worth it before making the trip.

I have a lead on some late 70s, early 80s La Scala Industrials. The pictures show pretty bad shape on the outside, but the seller says they function perfectly. Seller is asking $500. What do these usually go for? I'm fairly familiar with value of La Scala, but didn't know how Industrial effects value. Thanks, Matt

Thanks guys. I think after digesting all of the great info posted, I think I will stick to the tried-and-true 24x24x24 internal dimension for the bass bin - it's not too different from what I had and bunches of people have had success with it. Why mess with a good thing, right? The port shelf I have seen for that configuration is 9" from the back of the motorboard with 50 sq. in. of port space. Does that sound right? Matt

I downloaded WinISD pro (had to use wine - I'm a Linux guy ;-) ) and interestingly it doesn't mention speaker depth at all. I would appreciate it if someone could explain the relationship. I would like to, if at all possible, keep the dimensions I have roughly the same and adjust the port dimensions to fit. Matt

Thanks, speakerfritz, Do you happen to know of any good, free, calculators out there? I would like to keep the dimensions approx. as they are, and hopefully the ports can be adjusted to match. Matt

I have not acquired the woofers I am going to use yet. My thought at the moment is the crites cast frame woofer, but I am certainly open to suggestions, especially where money might be saved ;-) Matt

Very interesting. I found the "Download PDF Cabinet Design" link to be of particular interest. The graphs for each of the 3 box sizes show somewhat different characteristics. Matt
