Roland,
The Solo 12" is a good sub but needs a lot of power. 200 watts rms and more per sub.
Another good sub I left off is a JL 12". W? depends on how you plan to use the sub and how much power you have. Both the Solo and the JL need to be in properly designed boxes.
Still, the best SQ sub made is IDQ 12" v2.
It runs off whatever power you give it in various box sizes and types.
dnewma04,
Yeah the transfer function creates lower frequencies than a sub can produce in the car.
But if you study acoustics it would state, "if these frequencies are created from a source that does not produce these frequencies (subs that don't play to 20 Hz), they are the result of error". This error is created by the compounding of waves produced by the sub and the boundary of your vehicle interior.
For accurate sound let the speaker produce the frequencies and reduce the effect produced as a result of the transfer function. Hard and soft obstacles in your interior and treatments to your interior panels (boundary) can affect the response resulting from a vehicle transfer function.
On the other hand Boston Acoustics? subs rely on vehicle transfer function to produce lower frequencies and they do sound good in some vehicles. But if you modify your vehicle with deadening and other techniques you may find that same Boston to lack bottom end in the same vehicle.
I did a better job of modifying my transfer function in my first SVT.
As a result of stereo subs, woofers and this technique I could get accurate detailed bass and it would stage left or right and not just in the middle. You need 100% stereo or Left or Right paned mono recorded CD's to hear effect of Left or Right staged percussion including lower frequencies.
Yeah, most recordings do not have this. Most CD?s are nothing but mono mixed down to left and right, so all your bass is mono and the more detailed you bass the more you notice that its in the middle.
You say sub is mono, you don?t know if its left or right. If you are in a room with a bass drum playing you know where it is by loudness only, not time and loudness of arrivals as with higher frequencies. This is why most can localize on 80 Hz and above frequencies. But even 20 Hz sounds are louder at their source than they are on the other side of the room. Yeah the difference is small and you need to be able hear
20 Hz to know one position is louder than the other. I guess it depends on how far you want to go for life like sound.
