Hi All. I picked up a pair 1976 La Scalas about a month ago and really, really like them. I got to thinking that I would like to build a diy set in two parts, separating the bottoms from the tops, and build them out of one inch Baltic birch plywood. My question is in regard to the ramps that create the horn shape from the hole in the woofer's motor board to the left and right back corners of the cabinet. Could these ramps end at the front of the flat parts of the doghouse that are parallel to the cabinet side instead? Would this result in a better horn that has a progressively increasing mouth size as opposed to a horn that has an increasing mouth size in the back where the ramps create it and in the front where the sloped doghouse and the cabinet sides create it, but a section in the middle that is not increasing at all? Please see the attached drawing, a very rough one, as it helps explain what I am talking about a bit better.
Hello everyone. Long time lurker, first time poster. I recently, about 6 months ago, acquired a set of La Scala's via CL at a very affordable price. They were road speakers (maybe) and covered in carpet. They sounded awesome but looked pretty rough (NOT wife approved for the living room). But the sound brings tears to my eyes (in a good way) with certain music. Sooooo I decided to modify the La Scala's (gasp). And one of the main reasons I modified it to a Khornish is because we just moved into a new house and the living room has large cubbies on either side of the TV that will act as a large corner for the doghouse. So I made a new front end on the backside of the La Scala so that the horns are now forward and the bassbin faces back into the cubbies. I painted the exteriors with Duratex and layed some rosewood veneer on the front. I also upgraded to Crites 120 tweeters and the new crossover to boot. I've included some of the pics. I should be done with them tomorrow morning and be able to test them out then. I have no skills (I'm good at demo) so this was a test for my meager skills and patience. Have to have the wife help me align the speakers for mounting and then we are all done! Any questions or ideas (or criticisms) are welcome. Enjoy the speaker porn I christen these the Mini-K's!
I love my klipsch pro media 2.1 so much that i decided to make them even better. For me these are the best computer speakers i can afford. I did these mods over several months, buying most parts from eBay (it takes 2 to 4 weeks to arrive from china). The most expensive parts were the control pod box (10 US$), the bluetooth receiver (7$) and the relay (8$). The other parts were between a few cents and 3 dollars). I am very satisfied with the result. As can be seen in the pictures, i completely detached the control pod from the speakers (because i had to move the speakers away from the computer), added some good quality gold plated binding posts, replaced the cables, added an on/off switch and a relay to the sub woofer so that the speakers automatically switch on and off with the computer. A 12 volts signal from the computer PSU controls the relay. I added a bluetooth receiver inside the control pod. On the front picture of the pod one can see an on/on input selection switch (select between the computer speakers and bluetooth reception from my iphone and ipad) and a blue led light in-between the 2 volume knobs. On the back of the pod is the power input for the bluetooth receiver (5 volts supplied by the computer PSU), the bluetooth antenna connector and the bluetooth on/off switch. I did not alter in any way the original klipsch circuitry. I did not want to power the bluetooth from the control pod circuitry as i was afraid to alter the sound quality.
I remember seeing something about this series a while back that now seems interesting… You see, I recently acquired another set of THSR’s. My last pair were THSR-2’s… so I had to build a set of crossovers more-or-less from scratch but adding the tweeter was easy (the THSR-2 uses the HII cabinet/motor board with only a small piece of ply covering the tweeter cut out). My new pair are the original THSR which came with a nice fully built E crossover but do not contain the cut out for the K77 tweeter in their HI cabinet/motor board. Because of this I’ve been going back and forth on what exactly I want to do with these… I could try to route out the opening myself but I’m not all that confident in my routing abilities? I’m also not a huge K77 fan and that is really the only thing that could possibly fit in that space. I also thought about just setting a tweeter of my choice on top but I would really prefer to keep the system self contained. Which is where the Beta comes in… I know I wouldn't exactly be using it for its intended purpose but it would allow me to add a tweeter without modifying the cabinet and the woofer doesn't spec out to be a bad K22 replacement? I guess I’m just looking to see if anybody thinks this coaxial woofer idea is crazy or not?
