The Level V product line offered by Hybrid Audio Technologies is our Legatia Professional Series. The Pro series is the finest car audio speaker offering in the world, bar-none. It has taken years to develop the first two Pro-series products, the Legatia L1 Pro tweeter, and the Legatia L1 Pro R2 (ring radiator) tweeter, an enhancement of the widely-acclaimed limited edition and now discontinued Legatia L1 Pro SE tweeter. The Legatia L1 Pro R2 has quickly become recognized internationally as the finest radiator ring tweeter available on the market today.
