Anyone heard the Gryphon Trident?

Only speaker playing at the unich show was the Atlantis. Trident and the rest of the line was on static display at 1st. floor.

Gryphonaudion, can the Trident be adequately driven by 18w SET?

that may likely be a trap which you could fall into, thinking that as long the bass is powered with a 1KW class D amplifier, you can power the rest with an 18 watt SET anytime.
have experienced many speakers which were self powered on the bass and such systems needed superb power for the 'top' too in the end.
i never experienced bi-amping with big transistors on bass and tubes on top as beeing correct to wholeness in time domain.
the "adequately driven" is something you can interpret..

Alectiong - The amplifier inside the Trident is not a Class D amplifier but a dedicated Gryphon Class A/B amplifier. 1 meter of heatsink of the backside is hinting at this...
Besides that, Tuboo is right,. merely "driving" a speaker is not the questions. There is no substitute for listening with your own ears, but given the high sensitivity and uncomplex load of the Trident, very low power is required and from a technical point, a tube amplifier could do the job, but subjectively it could be a poor choice.

The bass amp is Class A/B in the Trident. I asSume you have a large room, hence the question regarding the Trident. It is best with an all Gryphon rack. However if you have other electronics, and want a semiactive speaker, then I think a cheaper option would be the Adam Audio Tensor series, exceptional value and nearly there. I deeply respect Rockport, but the question is about active bass section so I will stick to the subject.
