In Reply to: You need more than a "decent measuring mic". posted by cheap-Jack on January 25, 2007 at 08:54:16:
Hi ,
I don't think you read the post correctly . I said that the measurement mic was next purchase on the list after the next power amp is built . I will be only be using the mic for ironing out anomalies rather than playing music and analysing that . I am surprised you measured such low notes , most mics are not accurate under 100Hz . What mic did you use ?'surprised you go for saaannnnd active pulse filters considering your tuby moniker.'
...this I do not understand at all . Where do I say that I use sand active filters ? When I went active I built the filters into each respective power amp . Both were 1st order , bass unit was a Jordan JX150 (ask Allen Wright about these) , HF was a DIY ESL panel 50 x 25cm . There are pictures of these in the archives if you would care to look . For the HF part of the system , which was a direct drive amp , the filter was a cap on the input . For the bass amp the filter cap was between the input stage and the concertina phase splitter .
cheers
