[QUOTE="Norval, post: 458757, member: 62"] These are great drivers if implemented correctly. Here are some issues with the Thor's (but that's just my very own opinion). 1) the x-over frequency is too high for a D'appolito configuration. Its also a bit high for those specific drivers due to the cone breakup. 2) The drivers used W18[b]E[/b]001 has a slightly smaller magnet than the W18[b]EX[/b]001, which imo is a bit of a compromise in the mid area. These drivers were selected due to their higher Qts, in order to get a little more bass. The notch filter as far as I know works OK, but I would suggest you take some measurements using SW (I'm sure Shaun could help you), and play around with the cap/inductor value. I have found a smaller inductor/higher capacitance worked better. Lower your x-over frequency to between1600Hz and 2000Hz. (mini DSP should work well) Your idea of 3-way using the 8" drivers is not bad. [/QUOTE]
