I&#039;m still experimenting with a few details, but these two drivers are winners for sure \u2014 a traditional full-range driver (copper) and a new design&#8230; a BMR driver (black). The BMR driver is interesting in that it projects sound more evenly so that there isn&#039;t as much of a sweet spot as much as an even field of sweetness&#8230; and yes, they both sound really, really good.<\/p>\n<p>They are both sealed designs making them great for bookshelves (no bass reflex tubes to create booming echo chambers) and both handle up to about 30W\/channel at their peak, which makes then great for single-room applications (think: office, bedroom).<\/p>\n<p><img decoding=\"async\" alt=\"Speaker-prototype_01\" border=\"0\" class=\"asset  asset-image at-xid-6a00d8345166b769e201bb0983275c970d image-full img-responsive\" src=\"\/norcalmod\/wp-content\/uploads\/sites\/3\/2025\/09\/6a00d8345166b769e201bb0983275c970d-800wi.jpg\" title=\"Speaker-prototype_01\" \/><\/p>\n<p><span style=\"font-size: 12pt\"><strong>Version-1: <\/strong>&quot;The Black Bomber&quot;<\/span><\/p>\n<p>The initial prototype uses a 3.5in BMR driver in a gray-washed baltic birch case with a lacquer and wax finish. Each speaker is approx 7(x)7(x)11 with ultra-high quality 5-way binding posts on the rear in satin-nickel. This speaker has an astonishingly great bass response with an almost elastic punch (not &quot;boomy&quot; at all &#8212; very tight). The BMR driver is unique in that it produces a fairly even sound field rather than a &quot;sweet spot&quot; more prevalent in traditional speaker cone design.<\/p>\n<p><strong>Connection:<\/strong> Terminal cup with Satin nickel 5-way binding posts<\/p>\n<p><strong>Size:<\/strong> 5X5X7<\/p>\n<p>&#160;<\/p>\n<p><span style=\"color: #ff7f00\"><strong>(SOLD)<\/strong><\/span><\/p>\n<p><strong>\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013\u2013<\/strong><\/p>\n<p><span style=\"font-size: 12pt\"><strong>Version-2: <\/strong>&quot;The Copper Core&quot;<\/span><\/p>\n<p>The full-range 3in full-range driver is set in a walnut front panel within a solid poplar case.
