Jefe Posted December 27, 2020 Share Posted December 27, 2020 I would expect my La Scalas to be driving me out of the room with the volume at 9 o'clock but it's not until I get up to 11 or 12 o'clock that they start getting loud. What could be causing this? Quote Link to comment Share on other sites More sharing options...

OO1 Posted December 27, 2020 Share Posted December 27, 2020 Sounds about right for a LasScala --your tube amp is rated at 35 wpc --- the speaker is rated at 100 wpc Quote Link to comment Share on other sites More sharing options...

The wpc ratings of the amp and speakers have absolutely nothing to do with the OP's perceived issue. Your La Scalas should be practically driving you out of the house at 10 watts, if not less. 1 Quote Link to comment Share on other sites More sharing options...

OO1 Posted December 27, 2020 Share Posted December 27, 2020 yeah right , the Laws of physics dont apply to Lascala's , and an amplifier that is rated at 70wpc , at 12 o'clock , does not produce more than 10 wpc --- Quote Link to comment Share on other sites More sharing options...

Peter P. Posted December 27, 2020 Share Posted December 27, 2020 Not all amps have a linear response to their volume controls i.e., 12 o'clock on a 35W/c amp isn't 17.5 watts, know what I'm sayin'? Usually they're designed with a lot of fine control up to the first watt. My old Yamaha amp appeared to run about 1 watt at 12 o'clock. But I'll bet that's not the OP's problem. Are they used LaScala's and somebody connected the individual drivers to the crossover out of phase somewhere? 1 Quote Link to comment Share on other sites More sharing options...
moray james Posted December 27, 2020 Share Posted December 27, 2020 means you need a very quiet amp. I have not measured but I doubt that a LaScala is 105 db efficient 101 db but not 105 db. Quote Link to comment Share on other sites More sharing options...

What could be causing this? Knob position isn't really a great factor in determining if something is not right... unless you happen to have history with that same set up. Changing one thing like speakers can change the entire 'ratio'... but generally the Klipsch LS should yield less movement/clocking on the attenuator than almost any other speaker manufacturer. What is your reference to something 'causing' issues? Quote Link to comment Share on other sites More sharing options...

HiFi Heaven Posted December 27, 2020 Share Posted December 27, 2020 Connect an analog AC voltmeter across your speaker leads at the amplifier. 2.83 volts = one watt. 28.3 volts = 100 watts. Quote Link to comment Share on other sites More sharing options...
