Ok din po gawa ni Master Larry Roxas
hindi na ipinagtatanong yan, Larry Roxas and his partner Lin Gomez are the "King of Horns" in the Philippines....
i did two 2A3 sets for camotecue some years back.....
just as Mang Rod is the king of tubes in the Philippines.....
Tony Rodriguez modfied a Sony 4 inch FR in a TL box, installed whizzers and phase plugs
and was able to eat the power that a PP EL34 power amp could dish out....
so much so that a guy at the exhibit approched me and asked,
"...sir, nasaan po nakalagay ang subwoofer nyo?....
did some snooping around, some guys from the states told me, Audio Nirvana speakers
are actually made in an OEM Taiwan factory.....all the while i was thinking they were made right here by Dai-Ichi.....
not that it matters, what matters is the satisfaction one gets, and like i always say YMMV....
neodynium motors for speakers gives the highest flux density for the same size as Alnico or ceramic ferrite magnet ones...and so is able to control the voice coil better.....
