As I stated in my earlier post, back in 1970, Klipsch used metal mid horns, which, at a louder volume, would ring and resonate. I believe this is what you are responding to. I suggest Dynamat, or another type of damping material, to dampen the outside of the horn. The bracket holding the midhorn ( near the driver ) to the doghouse, and it’s surrounding area, are also very resonant, especially at a louder volume, and should be damped..

Now that is what I call OVERKILL! |
You say you upgraded tweeters and crossover ,what about the mid range drivers? I replaced all components in in set of belles from Crites and it was a big improvement.im driving them with McIntosh 601 mono blocks,which is extreme overkill,only because I’m in between b&w’s right now.sold my 802 d’s and waiting for a set of 800 d2’s to pop up somewhere.

Allright I hooked my la scallas to my emotiva 2gen3 amp and much better sound all around. But I still get the fuzzy midrange when pushed. Now my question is why not compensate with an equalizer? Turn down the offensive frequencies instead of altering the expensive speakers. |
Yes I’m running both chorus and La Scalas.
its a 25-20 room and I like the surround effect. And I like loud music. |
Not clear on exactly what you are doing. You are running another pair of speakers (Chorus) along with the Klipsch? If so, why? |
I used to be a sound man for a wedding band and we played big venues with a 10k watt 3 way system. On the jobs where we would be in a smaller <300 person wedding, we used a single Crest 1000w amp with La Scalas. The amp had trim pots on th rear panel and we turned them down to 9:00 o’clock position and the Klipsches would astound all those who understood about sound. Fairly large rooms would be filled with concert like sound. They are incredible speakers. Now those same speakers are being used with a 2A3 set amp pushing around 3 Watts and still astounding people. They are great speakers.

Has anyone ever used a carver amp on the La Scalas? I have a 1.5 I could try |
I will give it a try and connect them to my emotiva 2 gen 3 amp. I will post with my results. Thanks |
Devault-Personally, I hate acurus amps. They can be really harsh and will push high distortion levels. 500 watts won't blow those mids, but 1/2 watt of distortion sure will... |
there is of course a genius...Nelson Pass...
First Watt.....
|
I punish my Heresy IIIs with a massive 12 single ended tube watts per side. They can take it, but after maybe a couple of watts I can't...too loud. |
I use a 2 watt SEP amp with my klipsch quartets (97.5db)
can get plenty loud. very nice at low volumes
|
devaultcarl1, Think instead of how LITTLE power they can take, and then try a 300b amp. It will sound heavenly. |
La Scalas with 250 watts available.
Loud!!! And lots of it.
|
used a stacked pair with Crown 300’s in the 80’s for a Punk/Rockkabilly band PA
pretty sure you will just hurt yourself IF you dont cliip your amps....
of course I used hearing. protection.....
|
I am always rotating power amps through my Lascalas. My Yamaha pro amps have a red led indicator per channel that show when 1/2 watt has been reached, and it is plenty loud for me. At the level the OP is listening, there are many areas of the Lascalas that are ringing and vibrating that should be reduced by dampening. The shoutiness and harshness spoken about is caused by THIS, and not the drivers. Dynamat should be used on the metal mid horns immediately. The Klipsch forum has much information on the subject. Enjoy ! MrD.

Don't listen higher than average of 85dB, or you'll ruin yourself.
|
All Heritage models are rated at 100 watts continuous 400 peak but they play so loud with so little power its unlikely you will be able to tolerate the volume they can produce with 50 watts.....
I have a pair of Heresy III, 40 watts will drive them plenty loud and clear. Ridiculously loud and not really even pushing the amps. Lascalas are much more efficient, so you wont approach your amp's max power if being sensible with the volume control |
Am I at the point where I need to upgrade my wires? Any good brand to look for and not break the bank buying them? |
Shoutiness and harshness are inherent in those drivers when pushed above 100db! Fooling around with the x-overs will not remedy this! |
Keep the.peak SPL's below 100db! Above that all the older Klipsch speakers begin to sound shouty and harsh! Lesson learned the hard way! |
I’m trying a acurus ss amp. I’m having trouble with the midrange if the song has a lot of mids in it they get fuzzy . Any ideas on what it could be or how to fix?
i have already upgraded the tweeter and crossover boards with bob Crites . |
I ran mine with 35wpc tube amp. They were more than loud at 12 o clock. I also ran a 135wpc vintage marantz and they handled it no problem. If ran too loud your ears will bleed. |
A-I've seen clubs use LaScalas. They can put out a ton of sound without too much power.
B-It's not the wattage that will blow a speaker, it's the distortion. Your ears will bleed before those will blow.
C-I ran my Cornwalls with 100 watt Threshold and never pushed the power output. 10 watts was fairly loud. |
You will love this. My friend asked me if I wanted a pair of big speakers. St the time I didn’t have a stereo system. But I said bring them over he showed up with a pair of Klipsch Chorus speakers. I was so impressed with them I built a new sound system to take full advantage of the chorus speakers. I ran into a problem when I tried to match another pair of speakers with them. They drounded out every speaker
i ran until I found the La Scalas they have the same sensitivity so they don’t drown out the others 😁 |
My room is 25-20, my La Scalas are 1970. I up graded caps and tweeters. They sound great I run a svs ultra sb16 with them. I like loud music but also like clean sound down at lower sound levels.
It’s great that a pair of (partly upgraded) almost 50 year old speakers can still bring joy to a listener - without any notable sonic degradation, that is. Certainly a testament to their longevity. My setup is quite similar to yours on the speaker front (my speakers are "modelled" around the Klipsch Belle), and I also use an SVS SB-16 Ultra to augment my main speakers downwards. With your large-ish listening room and desire for loud playback I might not suggest an 8 watt SET.. |

… So I don’t want to hurt them .
@devaultcarl1 -- In the context of the Klipsch La Scala's and their power handling I'd assume for above quote to be aimed at your ears. Sporting 104-105dB sensitivity you'll hit some 120dB's or slightly more with 100 watts, at the listening position up to some 3 meters away. That's a lot of strain on you ears. Indeed I'd lower above rated average wattage usage by at least factor 10. Don't know the size of your listening room though (and listening distance) added to how hard it's damped, which can change the estimations notably. How old are your La Scala's? |
And on the noise I bought a mapleshade noise suppression ground loop with double helix wound power strip.the lows are pretty black👍 |
Thanks bill, I bought the La Scalas to keep up with my chorus speakers. The chorus speakers would drown out any speaker I try and run with them. The La Scalas are about as sensitive as the chorus speakers
so there a good match sound wise. But power handling not so much. |
La Scalas are no where near 4ohms nominal. They are so efficient that your amp will only feed them on average about 20w/ch and "maybe" 75w with peaks in an average sized room. With that said, I hope your Emos are dead quiet because if not you could easily hear the noise floor during quiet passages.
