This 15 inch, 4 ohm speaker arrived and was intantly popped into it's cabinette whiich belongs to my "front sound system". This new speaker replaces a broken 8 ohm, same size speaker. it's driven by a 350 watt (rms) per side stereo power amp.
The difference in sound power (db) is amaising, sound quality too, has improved imensely.
To ballance left and right with a decibel meter, the "main out" slider driving the new speaker is now 1/4 lower than the other side wich still has an 8 ohm origional speaker.
My amplifier does recomend 4 ohms per side, I now know the difference, also, the amp runs cooler on the new speaker side.
What more could I want-maybe another 15 inch, 4 ohm speaker for the other side.
