Our HD3's are an all-in-one system with no extra components needed except your phone or computer. Simply place the speakers where you want them and connect the power supply. Next, connect the powered speaker to the right passive speaker using the included upgraded speaker wire with banana plug tips. Finally, plug in your music (cell phone, turntable, computer, laptop, etc.) with the supplied cables or via Bluetooth and you're ready to go!

Absolutely! This is especially useful for connecting wired with newer Smartphones that do not have a headphone jack output. You'll need the correct USB-A adapter cable to connect from your tablet to the USB input on the HD3. These are generally available from the manufacturer of your tablet/smartphone, local electronic stores, or even online retailers.
The HD3 speakers do include detachable magnetic grills. The grills have thin rubber pads to prevent marks or damage to the finish or the cabinet, so your HD3s will keep looking great even if you like to remove / replace them frequently!
