In the past I've only had one 12" sub. Recently, I've been looking into two 12" subs. Just wondering the difference between one and two subs as far as sound. Do two subs just hit harder? I know that bass doesn't double, because sound does not add up like 1+1=2 when you add another sub. I'm looking into the new 12" Alpine Type R subs. So wondering whether I should go with one or two
by adding a 2nd sub thats a 3db gain...i would buy one more expensive sub(if you like alpine then get the Type X) or you can get one Alpine Type R and port it and its about as loud as 2 sealed
Quick Shot - I currently have the 12" sealed Q-logic box that holds one sub. I thought that sealed boxes made the sub sound louder..? Interesting. This sub will be in an inclosed area in the ported box for the one 12"? Never really dealt with ported boxes before. How do they change the sound coming out of the box compared to sealed boxes?
A ported box increses the sub's efficiency at a given tuning. The longer the port legnth, the lower the tuning. You can also give the sub more power because the port controls excursion.
the only problem i see with ported boxes is that they are larger than sealed so if you have limited trunk space then it might not work..also if your box is tuned too high and you run a lower frequency it will sound like @$$
adding a second sub with the same power now split between both will gain +3dB.. same as doubling the power to a single sub. however, most people double the power when adding another sub, either by using a second amp, or by halving the load on the single amplifier, so you really gain +6dB that way which is roughly twice the bass (audibly) double the audible volume is between +6 and +10dB.. depending on the scale and who you ask.
there's no real drawback to two subs other than space requirements and power requirements though and of course, cost
