What is the x max on the stock woofer in the La Scala? I have searched here & found a few different numbers, I'd like to know for sure. Thanks...

OK, so does anyone have a link to a location that sells k-43's? I sure can’t locate any. There are no drivers of any kind listed on the Klipsch site that I can see. Yes, I do have 6 subs, and yes crossing them higher-ish would help... IF I didn’t have 12500 sq ft to cover. I’d need at least another 6 to have any impact with that route, even with the long throw. I have timing & dispersion issues as it is! Gary, glad to hear about the vinyl... I have thousands! I had removed my 33's long ago, but thank you for the offer. Nice work btw. Fran, your post made me think, then re-think. I really don’t know what difference a port will make in my application (yes, I play very loud). I can read all the posts here with various numbers... but I’d rather follow my ears. With that, if I go this route I will build a simple under-box port (using dimensions found in this forum) and see what I get. If it doesn’t do much/anything, I can simply put the stock bottom on and call it a day. I do face a bigger issue then all that are here with this... as mine are flown. Hard to believe, I know, but they were. Without the benefit of the floor/walls, I loose much of the bass right off the bat. Not really any way around it though. I do think my original k55's (in the k400's) are ok, so yes I’d need new caps if I stay passive. I do need new tweeters. After reading much here, I think I may run active... depending on how I do this & with what drivers. My favorite thing about the LS was the mids. I do hope they still fire ok, but if not I’ll go with something different (which from what I can see would result in new horns). If that’s the case, I’ll definitely go active. Although I was looking at bms drivers, after looking at their site I’m not sure they have a 15" that will work in a folded horn. I’ll have to chat them up & see. Boo.

Thanks for the replies! I can attest to that! I can't say the replacements I used sounded any better, if at all. They were louder though, but not as tight. That was the issue with them to begin with really... that the poor high's (little sound & poor dispersion), and after years of use they sounded sort of dead (lifeless). The woofers are not that much more $$, so I don't mind trying them out. Does anyone have a link to a place that sells the k-33's or 43's? I'll certianly have a look. What ever drivers I go with, I think my plan is to refurb one speaker, and see how it sounds. I don't want to purchase 10 sets of drivers and find it's not what I'm after! I've had a look at what I have, and I guess I'm lucky as their all AA crossovers. The Heresy's are all origonal (meaning not the II or III) so I can assume they have the type E... are the E's ok to work with? Not much onfo on them here from what I can find. Sorry if this is a dumb question, but is the port size based on the cabinet, the actual driver used, or both? In looking around this forum, I see there's ports through the bottom & out the front, ports only through the top & out the back, and yet another who ported from the bottom but cut into the top & blocked the back... some with tubes & some without. Seems to be several formulas for the ports, but I don't have enough knowledge to figure the math. I know the port will give me a bit lower hz (and maybe a bit higher db)... but I'd want to keep as much of the tighter horn bass that these are known for so I don't want to over-do the port project! The bass in today's music (not counting hip hop) more or less needs more in the 40-60 range then the LaSclas have. I'm asking because it may lead me to one driver over another. Maybe I can replace the drivers & have a listen, if it's not enough... try the low port idea and hear the difference.

I'm a bit north of Boston. If I need parts I'll message you for sure.

Ugg, I typed that in 5 or 6 paragraphs, yet it posted as one! Not sure how to "reply" here yet!

Thanks for the replies! They will be used in a Pro Audio set up, not home use. I have 12500 sq ft of floor space to cover. Currently Im using 6 mackie SA1530zs & 4 mackie 408's (eaw loaded-which means rcf loaded). I was considering swapping them out for RCF pro4's or BMS Codas, but with the cost of them I figured I may be better off just bringing my Klipschs back to life. Im sure I can load the La Scalas & Heresys and blow them away, and maybe for less $$. I have subs... six CV earthquakes, so the low end is covered. Its the volume in the 50-80 range I want to improve. I dont know what woofer I should go with, but from experience I know most that Ive tried in the past need spacers (they hit). It would be nice to know what would work well. The subs are not always on, so it would be nice to extend the range of them a little lower. I read a few threads here where people ported with good results. Some used the top & went out the back, others used an added vent on the bottom. Is there a consensus as to which method is better? All are from the late 70's or very early 80's, so Im sure the crossovers could use some help. Thanks for the Crites link, seems reasonable. For drivers, I was leaning towards BMS for a few reasons. I do love the actual Pro stuff from JBL, but theyre pricing has gone through the roof over the years! I loved the old bullets, but theyre no longer making them... not sure about the replacements, havent heard enough to form a valid opinion. JBL repairs are very overpriced. BMS has become the high end standard in club installs these days, with great results. They do make drivers and/or horns that would appear to fit my cabs. Most of all, they sound great (the few Ive heard anyway). I will stay with a dedicated mid. I am open to other suggestions for brands though. I think Id rather stay passive, but Im willing to run biamp if I need to. Basically, Im willing to do whatever I need to. I do like many of the mods here... the braces to firm up the sidewalls (from experience, anything other then the oem woofer needs them), the little corner pieces in the rear of the bins seems like they would be an improvement. Smart people here. Although Im looking to bump the volume & dispersion here, please understand its with quality in mind!

I have six vintage la scalas, and 4 Heresys (actually had 12 la scalas for many years). They were always used in a commercial application, but I took them out of service a few years ago. Over the years we blew woofers & had replaced them with eminence (dont remember which 15, but they were I believe 400 watt). Im considering putting them back in service (the la scalas, and maybe the heresys)! My original thought was to basically use the box & fill it with new drivers from bms or jbl. After reading the forum posts from many knowledgeable klipsch fans here, Im left confused lol. First, I dont think the crossovers have ever been touched. How can I tell if I need them re-done/updated/replaced? They do function. If I were to replace the drivers, I would probably need to replace the crossovers... unless I can match the new ones. Ive always loved the mids in these. The highs... not so much. OK, not at all. Always left wanting. The bass, although tight, never hit low enough or produced enough volume for me. Im not familiar with many of the mods done here (brands etc). Just a guess, but Im thinking most here are more the audiophile (home use), and less the contractor/club sound type. If so, should I bother looking into the mods/brands used here? Dont get me wrong here, just wondering if most of whats here is based purely on sound quality. Anyway, should I start at the crossovers & work my way up? Or, should I gut the things? Any advice and/or guidance would be appreciated. Thanks, Marc
