"""Just turn the music a little louder.""" That IS effective. The fan on the CX series is a louder than the PLX2 series. I believe the CX is very similar to the RMX series as they are heavy with big transformers. The CX was intended for permanent install. Those three series have the same Fan changeout method I believe.

I'm glad I did it. The fan is on .....more quiet than I imagined. The available youtube videos of this fan exchange do not do justice. I thought of doing one on my own.

Great restoration of a classic

This search engine list could be helpful making a choice.....

OK. So I changed out the fans on two different QSC CX amps. The process is a Pain in the A$$ really. No formal screws....just plastic snap-ons and having to deal with not tearing the Cardboard. https://www.digikey.com/product-detail/en/nmb-technologies-corporation/3110SB-05W-B20-E00/P14751-ND/2615564 So I installed the above fans....yes in the correct direction. These are silent. You can't hear them. Barely feel airflow.....but it is working. One may consider getting the same fan but slightly different version with a little more air flow and a little more noise if you are gonna push the amps. The stock fans are too noisy in the home. jc

Fantastic

agreed

Thing to do here....send your wife to a spa.... Then sneak them in and setup as best you can for looks. Then go to the BMW dealership and get her a white BMW. Works every time. jc

Lucky dawg............... the two closet HD from here won't rent those.

Ok. I might be talking out of my head..... Now I question whether I'm mistaking for something else.

Yes there is Tom. The schem is on my computer at home.

stunning work.

Out of curiosity, model with same parameters with this driver...... http://www.eminence.com/speakers/speaker-detail/?model=Delta_12LFC

So what replacement fan did you use?

Wow. 19 dB rated. I think my AC floor vents are louder than that.
