Frankly I don't need this explanation about Najda, I know it all - only wanted to point at its existence which can not be denied. For some people it will work. For us snobs loyal to our PLLXO solution, this device can be used for some basic experimen...

[quote user="Romy the Cat"]Gordan, this is slightly different concept. The presence of multiple outputs with volume control does not assure that each of the channel has own time delay circuitry. Plus it look like Najda does volume at d...

here's the measurement we've got from S3 on tractrix 260 horn. the increments on the graph are 1db it seems useful from around 450-500 to some 1.3k, but it still looks very bumpy in comparison with a number of ot...

While seeking for a CD capable of covering a low mid range, say from 300hz or under, I am offered a pair of TOA compression drivers of rather impressive size. Unfortunatelly a seller has no clue what model it is, except "it sounds as seducing as ...
