Question about Car Audio & Video
Thanks for choosing FixYa Larry.
I am an independent Car Audio Shop and have been working in car audio since 1993.
It is very common for different sized speakers to be used in a SQ (Sound Quality) setup like you want.
What the tech is suggesting is fine - as long as the crossovers are set properly.
What you're aiming for is to use the 10" for MIDBASS. This is the frequency that is between Midrange and Bass - so it is aptly named.
When you have Only Door speakers for Highs and midrange... and 12" for sub bass frequencies - there is an entire range you are missing.
Midrange should be crossed over to play no lower than 120Hz (door speakers)
MidBass should be crossed over to play from 120Hz to 80 Hz (10" subwoofer - used as midbass)
SubBass should be crossed over to play 80Hz to 35Hz
The 10" being in a sealed enclosure will give you tight & accurate midbass (guitar, bass, drums etc.. ) and give you a good kick. The tradeoff with a sealed enclosure is low power handling. The 10W7 handles the 500W all day long!!
The 12W7 will handle 500-1000W all day, and will provide the power and air displacement for the booming bass below 80Hz (Bass, Drum, etc) so it seems your amplifiers are well matched.
I would suggest having the car RTA tuned after the install is complete to be sure your gains are properly set. You dont want one range overpowering another.
Go with the single 10 & 12 sub setup... you may even be able to modify your current enclosure if they are seperate chambers.
Using (2) 12w7s will not give you the SQ setup you are looking for - and you will be missing the midbass range that is so prevalent in Jazz music. It will be overpowering and inaccurate.
