Who's the local audio guru?

You know exactly what was meant by the statement.

How about I add a word in there, "perceptively". In the correct box, two 10's can play PERCEPTIVELY lower than a single 15, until you put the 15 in the same style box designed for it.

Better?

Not lower, louder, and you know what I meant when I used the 10 and 15 inch sub, I'm talking about two of the same style speaker, a tweeter is designed to play highs not bass, subs are designed to play bass not highs. The metaphor is based on alike speakers not a 1 inch tweeter and a 15 inch bass speaker. I am not talking about db (thats volume) ranges I am talking about hz (thats sound) ranges. Two subs "perceptively" hit louder (db), not lower. They will reproduce the same frequency ranges (hz) neither will hit lower. A 10 inch sub will reproduce 5hz just like a 15 inch sub will, the 15 will do it louder because of the increased surface area.

And a 1" tweeter will play a 15khz tone louder than a 15" subwoofer, doesn't mean the sub won't do it, and visa versa.

Because the one plays lower tones louder, it is perceived that it plays lower.

Using your logic, a tweeter can still play a 5hz tone. Don't believe me? Give one a 1/2w @ 5hz and see what it does. Does it move? That's because it's playing.

You're arguing tomato and tomahto. You knew exactly what was meant and are trying to argue specific terminology when we're talking theoretically and perception; you can't do it.

Get off it.

Now you've said it correctly it is "perceived" that it plays lower. For someone who seems to know alot about car audio, you sure son't like to portray that knowledge correctly. I am just trying to convey the ideas correctly. Why tell someone something incorrect, why not educate them so they have that knowledge.

Perceptively is simply a different tense than perceived. They're the same word, same meaning, just different tense. Which means I was correct in my first response.

perceived definition |Dictionary.com

perceptively definition |Dictionary.com

To say, "It plays perceptively lower," is the same as saying, "It is perceived to play lower."

I get agitated when told I'm wrong, especially when I'm not.

Beyond that, you still knew what was meant, even though I missed/left out a word. So, in context, my statement was not false in that the meaning was clear; it was just done with fewer, less than optimal, words.

Got numbers?

I can take two 6.5's and hit even harder. IIRC they did somewhere around 146db. Talk is cheap.

Shows this:


Yes, that's me with the red box around my name and score. A single 15" subwoofer. 2nd place has four 12's and about $3k in his car and was roommates with the head judge.

[alexb!]

he hits 144 at bass race and if your local in panama city he will let you sit in it and listen for yourself
my two 10s hit 144 also jbls

Funny....
Another question.
Single 15" 100w RMS 8ohm 98db Sensitivity.
VS.
Single 15" 1200w RMS 4ohm 83db Sensitivity.
Which one is louder?

Well to get a 3 db gain in volume you have to double your power, so at 100 watts, lets say you get 100 db (just for simplification) so THEORETICALLY,
200 watts gives you 103
400 = 106
800 = 109
1600 = 112
So 1200 somewhere in the neighborhood of 110

The 98db and 83db sensitivity is saying that at 1 watt one sub hits 98db the other at 83db this doesn't scale so you can't tell which will be louder from just this information.
