"Inside the Grand Veena
A veena (in case you've been wondering) is a musical instrument from southern India that looks like the offspring of a lute and a sitar. The Grand Veena is Reference 3A's latest venture into the market of speakers of near to full frequency range. With two 8" woofers covering the bass, a 6.5" midrange/midbass driver, a dome tweeter, and a ceramic high-frequency exciter/supertweeter operating above 20kHz (more about this later), R3A's intention for the Grand Veena is to leave no frequency uncovered, even those usually considered inaudible. With a rated sensitivity of 90dB and a resistance of 5 ohms (+0.5 ohm), the speaker is compatible with most amplifiers.
The midrange/midbass driver is the Grand Veena's heart. It functions unfettered by electronic crossovers or capacitors, which makes it extremely sensitive and responsive to musical information. Its operation is regulated only by the sealed enclosure, which starts rolling it off with a mechanical first-order, high-pass crossover at about 94Hz; its low-pass mechanical fadeout starts at around 3kHz. Cone breakup is minimized through the use of such materials as carbon fiber and an intrinsically rigid "hyperexponential" shape (like the bell of a trumpet), which also helps it achieve its goal of maintaining phase accuracy across its frequency range. That goal is aided, too, by an unusual blunt-ended phase plug in the middle of the driver."
