External Amplifier Comparison For Tweeters

First The Tweeters

TS-120TWM vs TS-S20

When using an external amplifier, the Pioneer TS-120TWM is generally the superior choice over the Pioneer TS-S20 due to its significantly higher power handling (100W RMS vs. 50W RMS). This allows the 

TS-120TWM

 to safely handle the increased output from an aftermarket amp while delivering a fuller soundstage thanks to its lower 1,400 Hz frequency cutoff. 

Why the 

TS-120TWM

 Wins with an Amp

High Output Stability: Designed to manage up to 450W peak power, it remains clear and distortion-free even at high volumes.

• Seamless Integration: The in-line high-pass crossovers protect the tweeters from low frequencies that can be amplified by external power.
• Broad Frequency Range: It covers more of the vocal range (down to 1.4 kHz), whereas the 
  TS-S20
   functions more as a "super tweeter" starting at 3 kHz. 

Recommended Amplifiers for These Tweeters 

To get the best performance, look for a compact 2-channel or 4-channel amp that delivers between 45W and 100W RMS per channel at 4 ohms.
