Well, APRS doing more studies, especially in the Contents of the advantages of ELECTRICITY and output are rotten, transistors and PDO are too powerful. But even when we just get a good sound if you put a qualizer just before, just to boost the signal for rcuprer the "softness" of the amp. Returning 6 dB max, if it is saturated just have something pretty good if we have good Hp. For example, RCF, Eminence, Beyma.
I'm trying to calculate in practice the power of this amp .... under 8 and under 4 .... we will see the rsultats.
