Different Size Subwoofers
 
I was thinking today, (and did a little research), about utilizing different sized subwoofers in the same box. Most people said you wouldn't notice any difference. I was thinking an 8 or 10 for better louder highs, and a 12 for a better louder low. It would be unique looking, but does anyone have experience with this? Would it make sense to do this at all?

You should cross them over at different points to be effective. Otherwise you will be wasting your time and money.

I apologize, I have installed a system before (Blindly), but am not sure about crossing them over. What does that mean exactly?

I'll bite, as well... in laymans; do you refer to literal placement of the items, or the crossing of neg/pos between the two speakers?!

And if it's the latter, what the hell does that do in terms of what you hear? That phrasing doesn't quite express my query, though... what do the two units do to each other that affects the result?!

By crossing over he is refering to using a crossover to send different Htz frequecies to the subs.

lower, say 30-100Htz to a 10" sub and 100-250Htz to the 8" sub

BThresher183 12-27-2012 09:04 PM

Oh I see, so that the respective frequencies go to the correct subs. That makes sense. Although....how would you do that? Ha

Some amps have seperate crossovers for each channel. Or you can use external crossovers or bass blockers.

BThresher183 12-27-2012 09:19 PM

Gotcha, I'll have to look into them a bit more. I will be slowing building a system, and am thinking of something like that setup.

some amps have crossovers, or you can hook up a crossover to the entire system. example you dont want your tweeters to receive any lows.. also if the box is split... subs in sep compartments make sure each is built with proper internal area. typically sealed boxes can have and smaller area and ported... hole have to be bigger, but hit harder in my opinion. sealed boxes have a cleaner hit

unless the subs have the same specs (power handling, frequency response. . .) you will need to make sure that if they are in the same boc that they are sealed in seperate compartments since they can move at different rates. will mess up the sound and could potentially damage the subs. they will most likely also need their own amp for each one in order to get them tuned correctly.
