| Re: i really need help q 18 - rlp 15 rlp 18
The default RLp-15 parameters are wrong. When creating a new driver in WinIS Pro, enter only the following parameters:
Qes
Qms
Fs
Vas
Mms
Re
Le
Xmax
It will calculate all the rest for you. If you try to enter any more than that, it will cause errors because the published value may be something like 1.1 when WinISD really calculates it to be 1.092568, so it will refuse it. So again, only enter the parameters I listed.
You can't really define bass sound quality, as some people like the sound of distortion and others don't. If you want to talk about accuracy however, the two 18"s should by all means be better than the two 15"s. I couldn't tell you which of the two 18"s is more accurate without seeing distortion measurements. Between the two 15"s, the TC 2000 offers a little more displacement and has a looser suspension, mating a little better with a larger enclosure and lower tune.
