&lt;p&gt;BS-1030W Universal Speaker&lt;br /&gt;&lt;br /&gt;&amp;bull; The speaker&amp;#039;s smoothly curved surface permits it to blend in with virtually all modern buildings. &lt;br /&gt;&amp;bull; A built-in matching transformer permits the speaker to be used for both high-impedance and low-impedance (8 &amp;Omega;) applications. The impedance can be easily changed from outside the speaker. &lt;br /&gt;&amp;bull; A splash-proof design enables the BS-1030 to even be installed outdoors in a location not directly exposed to the elements such as under eaves. &lt;br /&gt;&amp;bull; Mountable to wall surfaces directly or using with supplied or optional mounting brackets.&lt;/p&gt;&lt;table class=features&gt;&lt;thead&gt;&lt;tr&gt;&lt;th colspan=2&gt;Features&lt;/th&gt;&lt;/tr&gt;&lt;/thead&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td class=feature&gt;Type&lt;/td&gt;&lt;td&gt;Wall  &lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=feature&gt;Single/ Pair&lt;/td&gt;&lt;td&gt;Single  &lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class=feature&gt;Wall mountable&lt;/td&gt;&lt;td&gt;Yes  &lt;/td&gt;&lt;/tr&gt;&lt;/tbody&gt;&lt;/table&gt;
