Thanks for the tip, but I checked the fuses first...no luck

I have a set of 2000 K-Horns with AK-3 cross-overs. One of the speakers has lost 75% of the higher frequencies, volume wise.(sounds slightly muffled) I disconnected the tweeter and attached the speaker lead directly to the nodes to see if the volume or frequency response was lacking. To my ear, it appeared that the tweeter is in good working order. Are there any other easy tests to check why I have lost tweeter performance? Is this probably a cross-over issue or do I need more testing on the tweeter? If it is a cross over problem, suggestions for replacement cross-overs? I enjoy sharpness at the high end.(bright and open is my preference) Thanks

I bought an Apollo in December and it feeds a McIntosh 6500 which drives my Klipschorns with AK-3 x-overs. Build quality is excellent. Sound quality is excellent. However, I doubt the sonic upgrade is anything you will hear. ( I heard no audible differences) So buy it for aesthetic reasons or simply because you want a new player.

Unless your feline is a complete klutz (and most are very careful) , I'd leave it alone and let the cat utilize the ultimate hiding spot. Besides, it will save time dusting!

Tom: The La Scalas were toed in and focused directly at the listener(me) Also, I noticed the AK-3 network has an overload fuse circuit. Does anyone happen to know what rating the fuse needs to be?

As my previous posts have noted, I am a long time Klipsch fan. I first heard a pair of La Scalas when I was 18 years old.....and I never forgot the impression they gave (or the ringing ear drums) In 2005, (25 years later) was able to procure a pair of 2004 La Scalas, with the newer AL-4 crossover, and delivered them to my music room. A wonderful reunion had been realized and life was good. However, like any curious soul, I couldn't keep from reading about comparisons by others regarding Klipschorns and La Scalas on this forum. Well, 2 months ago, fueled by forum opinions, I procured a set of 2000 Klipschorns, with the AK-3 crossover. This is the story of my listening experience between the two Heritage heavyweight contenders. The setting: The music room is 22x25. Acoustical tile ceiling is at 7-6. Full carpeting. Stuffed furniture, bookshelves, and four perfect corners. Horns were placed on the 22-0 wall, the La Scalas were placed just inside each Khorn, against the wall, toed in and raised one inch at the front edge. The listening chair was positioned 10-0 away from the wall....dead center. The music reproduction pieces: McIntosh MA-6500 Rega Apollo CD Player Monster cable to all loudspeakers The music: Various selections from "The Man from La Mancha"(1964 cast), The Rolling Stones, The Kinks, The Flamin' Groovies, The Clash, and The Sonics. The music was picked based on specific passages highlighting highs, base, and mids.The MA6500 is especially useful for comparisons because a switch on the remote allows the switching between one set, the other set, or both sets of loudspeakers...without moving my head/ears. Comparing two loudspeakers with comparable Db outputs makes volume adjustments a non issue. The impressions: I never thought I'd ever need another loudspeaker system after I bought the La Scalas. I was skeptical about the supposed base extension in the Khorn but ultimately coudn't dismiss all the fuss and accolades from this forum. Even without comparing the two speakers, the first listening of the Klipschorn produced an obvious difference of an extended bottom range but I could hear no memorable difference in the highs and mids. So I lined up the speakers....side by side....and fired away. The base response isn't even close....the La Scala is a punch while the Klipschorn is an earthquake. It's unbelievable to hear the difference....switching back and forth....same music with such different results. I actually love the "in your face" punch delivered by La Scala...but for listenability and accuracy and all that other "audiophile" hoopla....hands down, the Khorn is a better machine. It simply sounds and feels better. Now mids and highs were very interesting and I'm curious to know from other members if they have experienced similiar results. The AL-4 La Scala sounded a bit cloudy...like a veil or light cover had been placed over the drivers. The AK-3 Klipschorn was definitely more open and exposed. I'm wondering if the crossovers are causing this difference or perhaps slight variations in the drivers? I was very surprised to hear this based on the impressive looking stature of the AL-4 network when compared to the less complicated AK-3 set up. I expected both mid/high ends to sound absolutely identical. Also, I believe the AK-3 delivers slightly more mid range than the AL-4.(which I personally prefer) Although various pundits have defamed the squawker in various Heritage speakers as being too aggressive, please tell me about a electrically amplified music event at which the midrange sound doesn't make your ears bleed. It is this mid which makes the guitar scream and voices penetrate. I believe it is this very squawker which provides the stunning realism we all enjoy! Conclusion: Gotta love those Khorns! I have ideal corners and locations and I never would have guessed that the two Heritage lines could produce such different sound. "Got Corners?" ...there is no question....

I agree with the 45 degree toed in positioning.....but don't forget to raise the front of the la scalas up about an inch. I use a small strip of plywood under the front edge.

Sounds like a great trip. The Hall of Fame is just plain awesome. I have a 6500 under warranty that isn't quite right and has a bubble behind the glass...I wonder if it's covered? Pete Rose read the same sign everyday in the dugout that every other major leaguer reads..."If you bet on baseball you will be banned for life" Pretty damn simple, but his arrogance and ego clouded his common sense. He got what he deserved.

btw...Don't forget to raise the front edges of the La Scalas about an inch or so above the floor. (LS are very directional) I use a strip of 1" plywood, the width of the speaker. Good luck!

Thanks PSG...a very helpful little chart. I can't take more than 3 or 4 songs at that volume...but I certainly listen at 105db for extended periods of time. I believe rock concerts hover around the 120 db level...wow!

I do not own an SPL meter but was wondering what the decibel level might be approaching in my listening room. Listening Room: 20x24 Acoustical tile ceiling at 7'-6"...carpeted and furnished. Sharp corners and hard walls. Listening chair is centered...3 feet from back wall...along 24ft wall.(15-20 feet from LS) Speaker: La Scala 2004, toed in along 24 foot wall...placed in corners. Toed up with a 1" block under front edge Amp: Mcintosh 6500 Source: CD Player Music: Rock ( i.e. Flamin Groovies, Nick Lowe, Ramones) Amplifier output: steady output bouncing between 2 and 25 watts..although I'm sure the exact output is more if it was measured digitally Curious to know if SPL can be estimated..thanks

I would be careful buying La Scalas at any price....It is well documented that these speakers have an uncanny way of causing their owners to smile at higher and higher decibel levels while inversely causing their neighbors to howl in protest. These speakers have been linked to permanent and irreversible evictions. BEWARE!!! YOU HAVE BEEN WARNED!! ACHTUNG!!

I smell a RAT....a dead one perhaps?

Congratulations on the new La Scalas. I'm sure you'll enjoy them for years. You may want to try and angle the la scala slightly upwards towards the listening area. I use a 3/4" x 2" x 24" maple slat under the front 1/3 to slightly elevate the front end. I prefer the sound delivery of this easy mod. 126mhz: My la scalas went for about $3850.00.

Sounds like a fair deal to me. La Scalas on Ebay in good shape command that price or more. New LS today go for around 4k.... besides the crossovers can always be modified . You'll appreciate the open and full sound as well as the efficiency. Best purchase I ever made!
