whats the difference 8" mid woofer vs 8" sub woofer
 

Hey,


i was looking in to getting an 8" speaker... i've come across 8" midwoofers and 8" subwoofers

Whats the difference??

Subwoofers im guessing will cover from like 40/50 HZ range and the midwoofers would cover like 70/80 hz and up range?

not a total expert but from what i seen subwoofers usually have frequency ranges of 25-250 midwoofers usually 45-3000/4000 but i seen some midwoofer/subwoofer drivers (cdt specifically) that does 25-1000

Only the intended application. I have seen subwoofers that would make excellent midwoofers, and midwoofers that would do fine as a sub. Find a driver that has the specs you want (ex: 30Hz+) and see if you can audition one somewhere. How the manufacturer names a driver (midwoofer/subwoofer/midbass) only gives you a general guide to the application.

Alright, yea cause right now i have 6 - 6.5 mids.. 4 - 1" tweeters, 3 - 10" subs
and it sounds like a still have huge frequency gap
so i was gonna do an 8" speaker in center dash and add 2 - 4" mids also

just wasn't sure if i wanted 8" mid offer or sub woofer

If you have a gap, it's in your set up or tuning. The drivers you have should easily cover the whole spectrum of music..adding more speakers will probably cause more cancellation and possibly make it worse...sounds like you have interference issues and/or crossover set up problems.

I agree ^
Maybe you could have your car tested somewhere?

yea i don't have a processor yet... so tuning is defiantly a factor

I guess it would be better to wait till after i get the processor and tuned to see :P

where do you have the subs crossed? the mids crossed? the highs crossed?

subs are 80hz , mids are 80hz, tweeters are 12.5 Khz

cause with out a processor thats what my deck allows :P

12.5kHz!!??! That's really high.

Your 6.5s probably give it up between 4-6kHz so you're light over a solid octave in an important range.

Drop the freq on the tweets or add a pair of 3.5-4" mids
