Getting The Best From Your QS350i

Suitable Amplification

The QS350i is an 8 ohm enclosure and can be 
connected in multiple parallel connections to 
an amplifier channel that can operate at speaker 
impedances of 4 ohms.

The QS350i is a mid power level high efficiency 
system, so ultra high power is not necessary 
to obtain high sound pressure levels. The 
recommended power range per amplifier channel 
is  350 - 500 watts RMS into an 8

Ω

 load or up to 

1,000W RMS into a 4 ohm load. An ideal partner 
to the QS350i are any of the Quest QA range of 
amplifiers. Setting the QA amplifier’s high pass 
filter at 35Hz is recommended for full range 
applications. If you are intending to add sub bass 
speakers, the high pass filter can be set to 80Hz.
