jon,
the beyma i heard is a 15" coax in a karlson box if i'm not mistaken. medyo ayaw pa ni lin gomez ng bass output kasi parang me hump daw siya naririnig because of the design of the opening. sa akin nga ok na tunog pero kuya lin will do some more tweaking. di ko pa nakumusta uli medyo nagbusy.
because of the sensitivity of the beyma and the box design, my 2a3 effortlessly drives it. 105 db yata yun. alam mo naman yung room ni lin sa store ang laki ng area. maganda i-experiment ung coax driver na yun kaya lang way outside my budget. kumpleto ang highs and lows. point source pa.
we tested the amp also with the big jbl horn speakers on display na napakinggan natin - the ones with three drivers. kayang kaya rin ng 2a3 idrive. if you will use this set of speakers at home i dont think kailangan mo ng high-wattage amp.
sorry jojo for the off-topic.
jojo, di pa ako makapagdecide kung 6v6 trioded output o trioded 6ar6. nakakabit na lahat transformers. wiring and time na lang kulang. i'm busy with room treatments right now.
