turntable3 Posted March 1, 2007 Share Posted March 1, 2007 Hello, because I know there are many folks interested in LA Scala II - charts. Here is one. Hope you like it. Jack Quote Link to comment Share on other sites More sharing options...
turntable3 Posted March 1, 2007 Author Share Posted March 1, 2007 Sorry for the bad quality. I try to make it better. Jack Quote Link to comment Share on other sites More sharing options...
turntable3 Posted March 1, 2007 Author Share Posted March 1, 2007 hope this goes this chart is showing the frequency-range and impedance-curve of LA SCALA 2. Jack Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 1, 2007 Share Posted March 1, 2007 Wow! That's pretty much the old rating of +/-5 dB from 45 to 17.5 kHz, except that the bottom is 50, instead of 45. Quote Link to comment Share on other sites More sharing options...
turntable3 Posted March 1, 2007 Author Share Posted March 1, 2007 Here is another one showing frequency-range (upper curves) and distortion factor (lower curves). Quote Link to comment Share on other sites More sharing options...
Guest " " Posted March 1, 2007 Share Posted March 1, 2007 There are some really strange things happening between 4k and 5K according to the first chart. While I was not surprised at the 70hz frequency response, I was surprised how sharpe the roll off was. Not a wonder why LaScala's sound better with a sub-woofer.

I'm seeing a roll off starting a 70hz. Each line between 40 and 100 is 10. Quote Link to comment Share on other sites More sharing options...
turntable3 Posted March 1, 2007 Author Share Posted March 1, 2007 It looks more badly than it sounds. I own La Scala 1 - built April 20th. 2006. I am very pleased with the sound. If the music is well recorded bass is very good. Ask the neighbour........... Because La Scala is very fast in the bass-response I am sceptical about using a subwoofer which tends to be not as fast as La Scala's bass. Yet I haven't heard a Scala with a sub. But I'll try it.

formica Posted March 1, 2007 Share Posted March 1, 2007 Ummm... fast bass? (... bass inherently has long wavelengths, and therefore is never "fast"... ). Perhaps youmeant controlled... In any case, with bass intensive material, Lascala's lack of lower endis very obvious and it will benefit from a good sub. Problem isif you like to crank them every once and a while... you'll need a lotof sub... nice charts btw... ROb Quote Link to comment Share on other sites More sharing options...
sfogg Posted March 1, 2007 Share Posted March 1, 2007 " There are some really strange things happening between 4k and 5K according to the first chart." Crossover point is 4500hz. Shawn Quote Link to comment Share on other sites More sharing options...
Deang Posted March 1, 2007 Share Posted March 1, 2007 A speaker with no low bass sounds 'fast'. Quote Link to comment Share on other sites More sharing options...
Jay L Posted March 1, 2007 Share Posted March 1, 2007 those curves don't look as pretty as ones i have seen [] Quote Link to comment Share on other sites More sharing options...
pauln Posted March 1, 2007 Share Posted March 1, 2007 Thanks very much for putting up the LS-II charts. I like the German technical terms. The LS II is using the AL-4 network, right? I have a question if anyone might try to answer: I replaced the AL-4 nets in my 2005 LS with BEC A paper in oil. My understanding is that since the new drivers for the mid and the new tweeters are slightly less efficient than their previous types (about -2dB), the AL-4 network is hotter (less padded) in the mid and high end to compensate. Therefore, by putting the BEC A in there designed for the old style hotter drivers the mid and high are now relatively down 2dB compared to the woofer. Since the overall efficiency of the speaker is founded from the woofer (105dB with padding for the mid and tweet), the net result is that my LS have retained the original efficiency and have more bass? Or am I missing something in my assumptions? Is this a unique configuration? Any thoughts would be appreciated - I sure love the sound... And yes, there are nicer curves out there...

Jay L Posted March 1, 2007 Share Posted March 1, 2007 pauln, what your hearing is just as you stated in your post. the mid/hf level relative to the LF is slightly down in ouput from the stock AL-4. it will not however retain the same efficiency, though it should be close. by changing crossover topologies, you have also altered the voicing, which depending on your preference it may indeed sound better.

jbsl Posted March 1, 2007 Share Posted March 1, 2007 Qusteion for you Jay L: I have 2004 La Scalas and are the crossovers in mine the same as the La Scala 2s? Quote Link to comment Share on other sites More sharing options...
Deang Posted March 1, 2007 Share Posted March 1, 2007 Very close. You have AL-4's. When they went to the MDF in the LaScala II they had to make some adjustments to the network. I think maybe those changes primarily related to attenuation. As far as actual topology, they are probably near identical. Quote Link to comment Share on other sites More sharing options...
jbsl Posted March 2, 2007 Share Posted March 2, 2007 Sunday I'm going to compare some homemade ES500T and ES5800 (made by awsjr) to my AL-4s so I'll post what I think. Al Klappenberger's website with info on the ES500T and ES5800. http://www.alkeng.com/ Quote Link to comment Share on other sites More sharing options...
