Which one is better? Use 2 unit 10' subwoofer or 1 unit 12' subwoofer. Some people said, 1 unit 12' subwoofer is more powerfull than 2 unit 10' subwoofer.
Is it true? Any idea?
to all sifus, when plp talk about changing turbo compressor wheel, does it mean they change the entire centre catridge or just the compressor fin wheel?
