For Optimum Speaker Performance - 16
For Optimum Speaker Performance
Use only quality speaker cable.
Speakers should have input impedance of 4-16Ω, DO NOT connect
speakers of less than 4Ω.
The higher the db rating of your speakers, the louder the volume
will be. NOTE: Higher wattage does not automatically translate to
louder volume.
Do not touch the speaker cone. BlueTube speakers utilize a thin
sheet of titanium as the speaker cone and can easily be dented.
There are no serviceable parts inside the BlueTube Speakers.
Do not spray polish or cleaner on speakers. See care of product
section for more information (Page 22).
Before use remove protective covers from speakers.
