Bose makes the L1 Personalized Amplification Systems for Musicians&amp;lt;ref&amp;gt;[http://www.bose.com/musicians/index.jsp Bose.com web site for L1 systems]&amp;lt;/ref&amp;gt;. Bose has been actively encouraging the use of the term L1™ for this product line, and frequently refers to it on their website&amp;lt;ref&amp;gt;[http://www.bose.com/musicians/]&amp;lt;/ref&amp;gt; as the L1™ portable line array.&lt;br /&gt;
