Neh4pres Posted September 18, 2016 Share Posted September 18, 2016 So, I just finished refinishing my 1980-82 lascalla's. After 2 gallons of Bondo and a gallon of duratec, they look great. During the restoration I found a piece of speaker surround when I removed the bottom. Even though all drivers worked well, one k43 was very deteriorated with dry rot and missing surround in places. I replaced both with crites aluminum replacements. No mods needed in these old cabs. So, the questions are. I have 2 k43's that could be reconed and used. I also have 2 generic 12" woofers I think we're used in a car setup. These are all 4 ohm speakers, and my pioneer elite does not accept 4 ohm. So I was thinking of building a custom bin with a k43 and 12" in series per channel. Will have 4 woofers total and 8 ohms per channel. Would this be a good setup? And can I drive the k43 without a crossover? I plan on powering them on B channel, which plays the same as front left and right, but uses the unused side channels in my 7.1 system, effectivity making it a 5.1 system with 4 front speakers. I was thinking of a compressed horn setup for the k43's and direct radiating for the 12", what design should I use for the k43's? Lascalla's bins? Jubilees? Or something different? Thanks in advance for all advice. Quote Link to comment Share on other sites More sharing options...
Neh4pres Posted September 18, 2016 Author Share Posted September 18, 2016 Also, who can I trust in the upstate NY area to perform a recone, or would I need to ship them somewhere? Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 18, 2016 Share Posted September 18, 2016 I am confused on what exactly you are planning so I may be off target. The k-43s are fine. Once they are reconed they will sound great. Yes, they will need a crossover. No, I would not bother mixing the "unknown" 12inch speakers into the system. It may be a large project for you if you try to build la Scala cabinets and refresh the K-43's. You would still need to find mid-range and tweeter sections and design an appropriate crossover. BTW, a K-43 is not appropriate for a Jubilee-style bass bin. Perhaps you should not be committed to the K-43's since they are in need of repair anyway. One possibility is to build a "cornscala", however I would avoid straying from the Bob Crites design - his components and crossover and cabinet geometry are tried-and-true. Manu of the other "designs" and choices I see around this forum are suspect IMO. 1 Quote Link to comment Share on other sites More sharing options...
Neh4pres Posted September 18, 2016 Author Share Posted September 18, 2016 Thanks for the advice, I am not trying to build a full range speaker, just want the extra bass from a custom bass bin. That would still need a crossover? One k43 is still in excellent condition, and both still work. I didn't know there was a issue until I took them apart. That's why it's hard to just walk away from them, and the lascalla's can always use some extra bass imho Quote Link to comment Share on other sites More sharing options...
Marvel Posted September 19, 2016 Share Posted September 19, 2016 In this case, even though I don't have any myself, I would buy or build a pair of subs to go with your La Scalas. That will be a better known solution. You could recoup some of your money by selling the K-43s. Your bass will already be a little better by switching to the woofers from Bob. The K-43s will be lighter on the low end, but upper end of the mid bass will be a bit smoother. Bruce 1 Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 19, 2016 Share Posted September 19, 2016 Okay, I have a better idea of what is going on. I agree with what Bruce posted. My advice is to build a subwoofer to supplement the LaScala. Unfortunately, the K-43 does not lend itself to being a subwoofer driver. The K-43 is desirable speaker and you would be able to sell it for between $100-150. Use that money toward another driver (check Parts Express for possibilities) and build a sub-woofer cabinet. Just my opinion .... 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted September 19, 2016 Share Posted September 19, 2016 Parts Express has some nice subwoofer kits with varying levels of effort required. I recommend 2, placed in the middle of any opposite walls. There is a paper floating around here that studied subwoofer placement. Four centered on each wall is the most performance-least cost configuration, but 2 is close. 1 Quote Link to comment Share on other sites More sharing options...
Neh4pres Posted September 19, 2016 Author Share Posted September 19, 2016 Will placing them like that give me timing issues? Quote Link to comment Share on other sites More sharing options...
Neh4pres Posted September 19, 2016 Author Share Posted September 19, 2016 I was thinking of the svs tube subs. Their just so expensive, and a good projector is my priority right now. Quote Link to comment Share on other sites More sharing options...
