Escalante Fremont for rock - they are very efficient (true 93 db.), very fast, and can handle enormous amounts of power. They are not the most accurate speaker, however, including being rolled off above 6 Khz., notwithstanding the ring revelator tweeter, and thus may not do full justice to cymbals for some jazz fans. In any event, balls they have and can knock you over with clean decibels (Escalante's Matt Waldron has evidently claimed that the speaker will reproduce a 60 cycle tone at 130 decibels if the speaker is "plugged into an outlet").
