It's as though your car's speedometer measured up to 200 MPH. There would be very little movement of the gauge between 45 and 65... it would only make it more difficult to read your exact speed.
I gave a simple review comparing the BIC F12 ($183.27) to a JBL sub (I paid 203.59) in the same price class.
Amazon.com has the Klipsch Sub12 right now for 299.99, the BIC F12 is $183.27. Simple math tells us this is more than a 63% increase of price, not the 30% you claim.
I didn't say the Klipsch was in a "prestige" class
, I said it was a different price
class. You said yourself that you "moved up" in post #1671.
My JBL was reference level near 50% of the pot setting. Being a logarithmic pot, this would mean 50% of the power as well, or 125 watts RMS. My BIC F12 is at or above reference level at a setting of 3. It is only 150w RMS total. According to what you claim, it would have to be already maxxed out at the 3 setting, logarithmic or not. Yet it is able to go at least 7.5 db louder at the 5 setting, with none of the distortion so audible with an amp being overdriven.
I fail to see your analogy of potentiometer taper as well, since using a linear potentiometer would prove almost useless in a gain or volume application. That is why gain and volume controls in the past used a logarithmic potentiometer to mimic how we perceive sound. Perhaps you refer to a modern digital potentiometer, which can mimic a logarithmic potentiometer for less money. http://pdfserv.maxim-ic.com/en/an/AN3996.pdf
1. You got the math wrong (in your favor) on pricing that's been current for at least the past week.
2. You fail to use facts, or back up statements with facts.
3. You continue to post how your sub is better in an thread for a different brand and price point.
For those three reasons, the credibility and relevance of your statements is suspect in this thread, and I will move on..
