Hola Raanan...one of the most important feature of the CLSs is called coherence. By this means that there are no crossover in the signal path...and they play the music full range. No problem with the phase also. Now, if you are just adding the tweeter, and using the same amplifier, be careful. Adding a crossover to the circuit of the CLSs in paralell connection can cause more problems and can damage your power amplifier, than just geeting more highs in the room...how are you adjusting the sensitivity of the tweeter and match the right amount of the signal to the tweeter and the CLSs?...Is you are missing highs, perhaps you have problems with the stat panels. If you still want to add the tweeter to the CLSs, you need another power amplifier with variable input signal, (volume control) to drive just the tweeters alone. With this setting, also you can seek for the right amount of tweeter level and will not harm the CLSs amplifier. Remember to have a crossover to the tweeter...some very fast tweeters like the ones that are made of ribbon and comes with a crossover inside the case of them. Don´t fire the tweeters to the front, because you will hear them ease. Place them to fire to the back wall...it is better to have quality than quantity...hope this can help!...happy listening, and remember: "trust your ears"!raanan said:I have just tried adding Sequerra T9s with great results.Oddly,there seems to be more bass too.The CLSs were not open enough in a heavily carpeted room,but removing the carpets screwed up th room acoustics.
There are several reasons for the issue of "CLSs not being opened enough" and one should not jump to blame the CLS just yet...raanan said:I have just tried adding Sequerra T9s with great results.Oddly,there seems to be more bass too.The CLSs were not open enough in a heavily carpeted room,but removing the carpets screwed up th room acoustics.
Moscode 600 with zero autoformers at the 3x position.kwr said:I find this an interesting call Raanan as I would have assumed adding a tweeter would have destroyed the top end balance - different wave form launch axis behaviour etc. What amp are you using to power your CLS?
Sorry, now you're touching on subjects beyond my direct experience so I can't really make any recommendation. I only read up on a few articles but that's about the extent of my involvements to room accoustics & treatments. Here are a couple of links I was able to find...raanan said:What diffusors can you recommend?
Changed 6 tubes on the Moscode 600,and the sound opened up.It has long been my experience that with time tubes age,affecting the HF response with stats.Same story with QUAD IIs and ESL57s-all the divine KT66s stop being divine after a year of use ,because the high frequencies are not there any more.As the process is so gradual,it is a never ending source of frustration,as you don't understand why a system that used to sound so involving has "paled."That is why the addition of quality tweeters,other than serving as a "smokescreen" for a problem,adds to listening enjoyment even if the problem has not been addressed at the source.Spike said:
