Kasi yung westRack they are using Transistors like you...2SC2922 and 2SA1216... halus they are they identical sa ginawa mung amp1... My question is kaya ba nang AmP1 ang 1000 watts double magnet T&T subwoofer speaker na nabili ko sa Raon??? Rule of a thumb kasi sabi nang pinag bilhan ko nang Speaker, I shud use daw an AmP with a Power Rating of 1600 waTTs para maganda ang sound nang Speaker...
there are three models on westrak 120, 200 and 300watts the 300watt model requires 6 TB34 transistors on 8ohms circuit design compliant. The diff from my amp1 uses same TB34 but in double barrel config symmetry with 16pcs 8pcs 2SC2922 and 8pcs 2SA1216. and a very large transformer almost the size of welding machine and can go 2ohms straight.
imho my amp3 will be most suitable for your spk. The raon guys must have said 1600watts peak. since my amp3 is 800watts raw
RMS output or 1600watts peak it will handle your sub as the raon guys referring.
This amp 3 is also been tested for 18inch xxx RE a P77K sub during the transhow last august at roadstar boot. believe it or not the test tone of 20hz shows an Xmax of 5 to 6 inches of excursion the bass was totally mind boggling. i wish i could afford those sub.
btw. by dec24 wala na ako sa pasay. will stay at my parents house in pque till jan.
if you can make it dec22 sa pasay mas ok.
