A Message from Genesis 

Congratulations! You are now the owner of one of the finest 
loudspeaker systems in the world! Based on the technologies 
developed for our flagship Genesis 1, the 450XS is our smallest 
floor-standing line array loudspeaker model with three front-firing 
ribbon tweeters and a 24-inch mid-range ribbon. Yet it delivers some 
of the imaging and soundspace of our largest 7-foot tall products. 

The Genesis 450XS loudspeaker system was designed to 
reproduce music at live listening levels with virtually no restrictions 
on dynamic range, frequency response, or imaging capabilities. This 
is what we mean by “

absolute fidelity

”, the ability to reproduce the 

musical event faithfully, as was intended by the performer. 

Standing 57 inches tall, 23.5 inches deep, and only 14.5 inches 
wide, the Genesis 450XS is a diminutive giant. By means of an 
active servo bass, response down to 16Hz is achieved, and the full 
range and impact of a symphony orchestra or a rock band can be 
reproduced. 

Please read this Owners Manual and Set-up Guide to get the 
maximum enjoyment out of your purchase. Also, if you have access 
to the internet, please check back at our website often. The address 
is 

www.genesisloudspeakers.com

We will put the latest updates, 

tips and tricks, and support for our owners on our website. 

 

Please write the serial number and purchase details of your 
Genesis 450XS here for future reference.
