A co-worker of mine told me that him and his brother built a ford fiestiva into a spl car. He told me he put 40 tweeters and twelve 6 1/2 two ways. In total is 52 tweeters. He said their going to compete in db drag. I thought this was a bunch of crab. He said that they measure the db's in freguenzy so tweeters would work the best cause of there high frequenzy range. I feel this is a bunch of crab but he put on a good story that almost made me belive him. Could you guys back me up, proving some true facts. sorry for the spelling

Hurry get me a steel hanger, elec tape, zip ties, a monkey and a snorgle. trust me i've ran wires with less

"they measure the db's in freguenzy"

Wouldn't it make more since that dbs be measured in dbs?

They measure SPL in decibels.

Now, I guess if you got enough tweeters you could make up for the low individual power handling relative to sub bass drivers.

You lose out on cabin gain help though. This reason alone is probably enough not to do it. Other than it sounding like a knife running down a chalk board.

They only meter from 120Hz and down..... sorry.

Also, there isn;t enough air pressure generated by tweeters to produce a usable SPL level.

Gus, if there wasn't that 120hz limit there would be no reason that enough tweeters couldn't produce high SPL levels.

Yes, I'm just trying to make the point that SPL isn't a bass only phenomenon.

Okay then, this is interesting to me because I dunno.....SPL means "sound pressure level", that much I do know. Do they measure sound pressure or do they measure volume in decibels? And if they measure volume in decibels, is it correct to say they are measuring SPL?

SPL=loudness. Anything under a certain frequency can only be heard as pressure in a vehicle. It has to do with wavelength and distance.

I don't remember much about this subject.
