Avantgarde Acoustic Duo GTThe GT stands for 'Grande Twin', and sums up one of the key upgrades over the standard Duo SD, as this model features two 12" bass drivers rather than a single unit. This naturally doubles the surface area and therefore will bring a great reduction in distortion, improving effortlessness and aiding projection. The bass module is now powered by a 1 kilowatt power amplifier, and naturally retains the DSP crossover technology that is so useful throughout

Check the gap!
Plugs work great. I will say for those reviews saying they got a dud. CHECK THE GAP!!! Both plugs were not at 0.030 as advertised. I gapped the plug and it worked perfectly.
