Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75T-8 can outperform &#8220;boutique&#8221; drivers that cost several times the price. The driver&#8217;s truncated frame makes it ideal for line arrays and ultra-compact MTM designs requiring minimal driver-to-driver spacing. Its low-distortion characteristics and smooth response provide exceptional clarity, detail, and dynamics. Features a black anodized cone, heavy-duty 4-hole cast frame, low-loss rubber surround, and gold terminals.<\/p>\n<p><strong>DL2107Mk02<\/strong><\/p>\n<p>1 x SparkFun Thing Plus &#8211; ESP32 WROOM<br \/>\n1 x SparkFun Qwiic MP3 Trigger<br \/>\n1 x microSD Card &#8211; 2GB<br \/>\n1 x Panel Mount 10K potentiometer<br \/>\n1 x Knob<br \/>\n1 x Slide Switch<br \/>\n2 x Rocker Switch &#8211; SPST (Round)<br \/>\n1 x Qwiic Cable &#8211; 50mm<br \/>\n1 x Dayton Audio Reference 3&#8243; Full-Range Drive<br \/>\n1 x Lithium Ion Battery &#8211; 850mAh<br \/>\n1 x JST Jumper 2 Wire Assembly<br \/>\n2 x Screw Terminals 5mm Pitch (2-Pin)<br \/>\n1 x Acrylic Blue 5.75in x 3.75in x 1\/8in<br \/>\n1 x Acrylic Purple 5.75in x 3.75in x 1\/8in<br \/>\n24 x Screw &#8211; 4-40<br \/>\n4 x Nut &#8211; Nylon Locknut 4-40<br \/>\n6 x Standoff &#8211; Metal 4-40 &#8211; 3\/8&#8243;<br \/>\n8 x Standoff &#8211; Metal 4-40 &#8211; 1&#8243;<br \/>\n18 x Wire Solid Core &#8211; 22 AWG<br \/>\n1 x Adafruit Perma-Prote Half-Size Breadboard<br \/>\n1 x SparkFun Cerberus USB Cable<\/p>\n<p><strong>SparkFun Thing Plus &#8211; ESP32 WROOM<\/strong><\/p>\n<p>PO1 &#8211; Analog A0<br \/>\nSW0 &#8211; Digital 21<br \/>\nSW1 &#8211; Digital 17<br \/>\nVIN &#8211; +3.3V<br \/>\nGND &#8211; GND<\/p>\n<p><strong>DL2107Mk02p.ino<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/* ***** Don Luc Electronics \u00a9 *****\r\nSoftware Version Information\r\n#16 - Sound - Dayton Audio RS75T-8 - Mk20\r\n07-02\r\nDL2107Mk02p.ino\r\n1 x SparkFun Thing Plus - ESP32 WROOM\r\n1 x SparkFun Qwiic MP3 Trigger\r\n1 x microSD Card - 2GB\r\n1 x Panel Mount 10K potentiometer\r\n1 x Knob\r\n1 x Slide Switch\r\n2 x Rocker Switch - SPST (Round)\r\n1 x Qwiic Cable - 50mm\r\n1 x Dayton Audio Reference 3&quot; Full-Range Drive\r\n1 x Lithium Ion Battery - 850mAh\r\n1 x JST Jumper 2 Wire Assembly\r\n2 x Screw Terminals 5mm Pitch (2-Pin)\r\n1 x Acrylic Blue 5.75in x 3.75in x 1\/8in\r\n1 x Acrylic Purple 5.75in x 3.75in x 1\/8in\r\n24 x Screw - 4-40\r\n4 x Nut - Nylon Locknut 4-40\r\n6 x Standoff - Metal 4-40 - 3\/8&quot;\r\n8 x Standoff - Metal 4-40 - 1&quot;\r\n18 x Wire Solid Core - 22 AWG\r\n1 x Adafruit Perma-Prote Half-Size Breadboard\r\n1 x SparkFun Cerberus USB Cable\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Wire communicate with I2C \/ TWI devices\r\n#include &lt;Wire.h&gt;\r\n\/\/ SparkFun MP3 Trigger\r\n#include &quot;SparkFun_Qwiic_MP3_Trigger_Arduino_Library.h&quot;\r\n\r\n\/\/ SparkFun MP3 Trigger\r\nMP3TRIGGER mp3;\r\n\r\nint iSongCount = 0;\r\nint x = 0;\r\n\r\n\/\/ Volume\r\nint iVolume = A0;\r\nint iVolumeLevel = 0;\r\n\r\n\/\/ EQ Setting Normal\r\nbyte bEQSetting = 0;\r\n\r\n\/\/ Play Next\r\nconst int iPlayNext = 21;\r\n\/\/ Variable for reading the iPlayNext status\r\nint iPlayNextState = 0;\r\n\r\n\/\/ Play Previous\r\nconst int iPlayPrevious = 17;\r\n\/\/ Variable for reading the iPlayPrevious status\r\nint iPlayPreviousState = 0;\r\n\r\n\/\/ Software Version Information\r\nString sver = &quot;16-20&quot;;\r\n\r\nvoid loop()\r\n{\r\n    \r\n   if (mp3.isPlaying() == false) {\r\n\r\n    if ( x &gt; iSongCount ) {\r\n\r\n      x = 0;\r\n      \r\n    } else {\r\n\r\n      x = x + 1;\r\n      \r\n    }\r\n    \r\n    \/\/ Play Track\r\n    mp3.playTrack( x );\r\n    \r\n  } else {\r\n\r\n    \/\/ Volume\r\n    isVolume();\r\n\r\n    \/\/ Play Next\r\n    isPlayNext();\r\n\r\n    \/\/ Play Previous\r\n    isPlayPrevious();\r\n\r\n  }\r\n\r\n}\r\n<\/pre>\n<p><strong>getMP3.ino<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/\/ MP3\r\n\/\/ Setup MP3\r\nvoid isSetupMP3(){\r\n\r\n  \/\/ Check to see if Qwiic MP3 is present on the bus\r\n  if (mp3.begin() == false)\r\n  {\r\n    \r\n    \/\/ Qwiic MP3 failed to respond.
