jambandfan Posted October 19, 2010 Share Posted October 19, 2010 Hey all, finally figured I'd throw some pictures of my first major-ish klipsch project up. I know you all usually post pictures of the whole process, but I have been waiting to get to this point and see them. Have not heard them yet. Let me know what you all think. BTW, if the belle like center board is going to be a problem acousticly, it can easily be removed, but I like the way it looks. I found a bunch of this wood at a local rockler when looking for ideas, and thought it would look pretty funky. No regrets yet, but I have not heard them.... Think I am going to grill off the top and the two bass bin ports. Any comments good or bad are welcome, as well as questions. Thanks -marc edit, need to add my pictures, cant figure out how, its not like the other boards I am on. I will get them up. Hold on. edit again, the help tab seems broken. I see the add images button, but my pictures are not online do they have to be? Someone want to give me a quick rundown..? Quote Link to comment Share on other sites More sharing options...
Marvel Posted October 20, 2010 Share Posted October 20, 2010 When you make a post, go to the options tab at the top (right next to compose), click on the add/update button. Browse to the file you want to upload. Once you choose a file you may need to scroll to the right to see the save button, but you need to save the file. Click on the regular post button at the bottom. Try to have them sized so they are too huge a file. Some folks still have rather slow connections. Note that you can only put one picture per post unless you have the pics hosted on another image hosting site. Bruce Quote Link to comment Share on other sites More sharing options...
Marvel Posted October 20, 2010 Share Posted October 20, 2010 It isn't too cumbersome... Quote Link to comment Share on other sites More sharing options...
jambandfan Posted October 20, 2010 Author Share Posted October 20, 2010 well hope this works. Let me know what youthink of the project, and also if you think I should use some batting in the new bass box. thanks -marc Quote Link to comment Share on other sites More sharing options...
Wrinkles Posted October 22, 2010 Share Posted October 22, 2010 Beautiful. That is one sturdy looking LaScala. Love the woodgrain, especially down by the slot. Quote Link to comment Share on other sites More sharing options...
jambandfan Posted October 22, 2010 Author Share Posted October 22, 2010 Wrinkles, thanks for the comments it is sturdy as hell. just fired them up last night, big difference from the cornwalls I have been running. bass is good, really good much improved from before. figure it needs some batting though? anyone? I changed to the ct125's as well. Tough to remember exactly what they were like before. Huge midrange on these things, thats what sucked me into klipsch in the first place. 3 feet in front of them you could swear my center is on.... Glad you like the grain, its pretty crazy.

djk Posted October 23, 2010 Share Posted October 23, 2010 Batting reduces midrange reflections from coming out the port, or back through the woofer cone.I don't think it is a big issue with the LaScala with it's slope sided rear chamber. You could put your ear up to the port and see how much midrange is getting out. If you want to try something, fiberglass ceiling tiles are nice to work with. Electric carving knife (or a steak knife) work well for trimming. Quote Link to comment Share on other sites More sharing options...
jambandfan Posted February 18, 2011 Author Share Posted February 18, 2011 So, I found a nice set of belles a couple weeks ago and I just cant keep both sets of speakers, as I only have one listening room. Loos like the belles will stay for a while, which means these lascalas are for sale. Email me if you are interested. Thanks. Quote Link to comment Share on other sites More sharing options...

jambandfan Posted February 18, 2011 Author Share Posted February 18, 2011 they are in southern NH. I am asking 1250, which is what I have into them, without labor here is a descrtiotion of the mods that I sent to a potential buyer. Thanks I bought a decent set of 88 lascalas about a year ago locally. Little rough, but well within my means to fix and upgrade. The tops needed some work, as everyone likes to put plants on these things, so I added and wood glues a 1/4 Baltic birch panel to them. Furthermore, I added a really interesting wood to surround the front of the speaker and stiffen the side panels. I also added in a center spar, that make them look something like a belle. As far as I can tell it has had no effect on the sound and looks great to me, but it could be removed if it was a concern to anyone. Then I upgraded the type AL crossover network with some help from AL K and Bob crites, two well known klipsch aftermarket guys. This was a large improvement over stock. Not being one to stop thinking, I took Bob crites advice and upgraded the tweeters to a custom horn of his designed to work with a very good selenium driver. The point of doing this was to increase the upper frequency range to 20K, the original tweeters only went to 17ish. This tweeter is also good lower than the original klipsch K77m and is capable of dropping down to 4500hz. What this does is allows the the use of a crossover that crosses the mid/tweeter to 4500 which is where the newer lascalas are crossed due to a new tweeter design. The reason they did this is that the mid horn on the lascala starts to get rough over that 4500 point. Then I built from some very nice components a crossover designed by bob crites to cross the mid?tweet at 4500. The capacitors are auricaps and are extremely musical. There was only one last thing to do with these speakers. On the klipsch forum, there are quite a few folks that have removed the bottom of the lascala, and built a ported bass bin to go underneath the speaker to gain response down to about 45-50 hz, from the original~60hz. This proved to work well and sounds very good. It also raises the speaker by 10 inches and for me puts the tweeter at a more desirable level. Overall, The speakers function perfectly and sound amazing. I would keep them, but I finally found a set of belles, and they fit in my room better. BTW the wood is ambroisia maple. Also, the Bass mod, is fully reversible. Thanks -marc Quote Link to comment Share on other sites More sharing options...
Johnny's Jill Posted February 18, 2011 Share Posted February 18, 2011 Very nice. I heard a set of these ported, sounds great. Craig 73 Quote Link to comment Share on other sites More sharing options...

chrapladm Posted February 21, 2011 Share Posted February 21, 2011 Sorry for the ignorance but what does the slot porting do? Quote Link to comment Share on other sites More sharing options...
Marvel Posted February 21, 2011 Share Posted February 21, 2011 Sorry for the ignorance but what does the slot porting do?The bottom of the LS bass bin is left open into the additional box on the bottom (with the slot port). The can effeectively get your bass response down to approx. 31Hz. You can also use two 4x7 inch round ports (pvc from the home supply store works fine).Bruce Quote Link to comment Share on other sites More sharing options...
