Contributions to TDK Wireless Boombox A73 (current version)

The A73 wireless boombox was introduced in 2012, and represents TDK's second generation of boomboxes. Unlike the first generation, this one has Bluetooth, a rechargeable battery, and a remote control. But collectors I've spoken to say it doesn't sound as good as the first generation. Partly because the speakers are smaller. On the front, it has two very small (5cm) full-range drivers, and two 13cm passive radiators. And there's a 13cm active subwoofer on the back. The output power is 2x7W for the front speakers plus 15W for the rear subwoofer. If true, that's more power than the old <a href="tiki-index.php?page=TDK+2+Speaker+Boombox" title="The TDK 2-Speaker Boombox (model TP6802) was introduced in late 2010 at $399, and offers very nice sound and build quality." class="wiki wiki_page">2 Speaker Boombox</a>, but not as much as the <a href="tiki-index.php?page=TDK+2+Speaker+Boombox" title="The TDK 2-Speaker Boombox (model TP6802) was introduced in late 2010 at $399, and offers very nice sound and build quality." class="wiki wiki_page">3 Speaker Boombox</a>.
The Bluetooth is Ver. 2.1 + EDR Class2, A2DP, AAC support AVRCP.
