I have the powered 901 Lifestyle Music System with Lifestyle 20 console that I bought used from a friend last week. They are working just fine, and the serial number suggests manufacture date of Dec 18, 2000. Have some questions.
1. How do I know for certain if the mounted 901 speakers are series 5 or series 6? Is there a way to know? Serial number 008472403530041AC.
2. Are there any standard tests I can run to be sure all drivers are working fine? The local service Center says they no longer support the product as it’s very old. Something I can do at home to check if they are in top condition technically? Since it’s been 17 years from manufacture are there any parts you recommend replacement? The speakers work just fine but just double checking.
3. The serial number is only on the right speaker. I can’t find any serial number on the left speaker that houses the amp and an integrated equaliser. They are genuine but wasn’t sure if that’s how they are meant to be.
4. I want to raise the speakers and place them over a 10 inch platform instead on the floor. Will be affect the sound quality or should be ok with marginal height increase?
Thats it for now and thanks in advance.
