ragjr Posted February 7, 2006 Share Posted February 7, 2006 I noticed that the new LaScala II is actually 1db more sensitive than the original yet I was told that the new drivers are actually 1 to 2db less than the old ones. So, how can that be? Does anyone know if the original specs of 104db 1w/1m were anechoic and the new ones I will bet have room gain added to the tune of 4-6 db. Just curious. If anyone is interested I have attached the frequency response curves of the some of the original heritage loudspeakers. Quote Link to comment Share on other sites More sharing options...
D-MAN Posted February 7, 2006 Share Posted February 7, 2006 There is a noticable trend of Klipsch "freshening" the specs. Since the "tests" conditions are not explained, take it with a grain of salt. Sensitivity depends on the frequency. And in the case of a "peaky" response, who knows - I might take the highest frequency peak and publish that, if it were me and I felt unscrupulous that day! Be skeptical of published specs by ANY manufacturer. It's always a safe bet! DM Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted February 7, 2006 Share Posted February 7, 2006 Could it be that the II's are using a thicker/stiffer MDF for the cabinet? Thus the new cabinet not flexing and absorbing as much of lower frequencies?? Quote Link to comment Share on other sites More sharing options...
jacksonbart Posted February 7, 2006 Share Posted February 7, 2006 But do they sound better? Quote Link to comment Share on other sites More sharing options...

The only purpose for sensitivity specs is to calculate the wattage needed for target SPL's. A lot of people confuse sensitivity with efficiency - and since both the old drivers and the new drivers have identical size diaphragms and waveguides, then the efficiency is going to be extremely close to identical.
