alright guys, when it comes to car audio i know 1 thing. the speakers make sound.
what i would like to know about is all the numbers involved.

Frequency range, dB, watts, etc.

i have some general knowledge of it all so im not completely braindead on the subject but you know, im not an expert in any sense. so any information that you could share is great.

also i jus bought some 6x9 alpine type-s sps-690a's in some enclosures to be the rear speakers in my car (1990 accord dx sedan). what have you guys all heard about these speakers and what do u think? i got em from ebay and am very eager to get em.

thanks!

 

so no one knows anything? woowee!

I can't comment on the Alpines. I have no experience with them.

 

Frequency: that range at which your speaker can accurately reproduce audio. 20 hz to 20khz= 20 hertz to 20,000 hertz is the normal range. Although the human ear is only good from about 40-14k.

DB: Decibels, a means of measure sound volume.

Watts: The nominal or maximum amount of power(wattage) needed for this speakers optimum performance.

Sensitiviy: The db produced by said speaker with 1 watt of power measured at 1 meter distance.

Does that help?

 

Forget the numbers, just go out and buy a set of speakers that you've heard and liked.

Listen to the salespeople. Try to distinguish the brands that they're trying to push. Usually, money = better sounding equipment. But there are a lot of products out there with low prices, that sound awesome.

Stick to reputable brands. Infiniti, Alpine, Boston Acoustic, JL, Kicker, MB Quart, etc. Newer brands may be just as good or better but there's nothing like having the assurance that your company's been making great products for years and years.

 

specs that the manufactor gives are BS and doesn't really help.

 

thanx for the link, very helpful.

i figured in the end i would basically jus being going by what i hear is good (hear as in the speaker, not rumors) but you know, it never hurts to know a few facts about audio and all that before you buy. thanks!
