I'm adding tweeters primarily for acoustic sounds and guitar synth, but will be playing electric through it, as well. The cabs will be powered by a clean, solid state amp. The VG-99 provides amp modelling and has output settings for line/phones, which makes it sound very good through a full-range system. I'm hoping that using an L-pad will enable me to dial-in just enough high-end to give a good balance for everything.
My cabs are Rocktron S112's (single 12" in ported trapezoid)...I have 4. Planning to add tweeters to only two of them and if the sound is too harsh for the electric sounds, I can put them on a separate amp and route my signals accordingly.
I'm just a little confused about how to wire the tweeters. I think I'll start by just using an L-pad with a series resistor in front of it (I was told this is the recommendation from the Motorola specs for the 1165's...to protect the L-pad). Hopefully, that will sound good...if not, I'll have to start experimenting with a crossover.
If I add a crossover, do I have to be concerned about the load on the amp? For example: the woofer (8-ohm) will be wide-open with a top-end freq. response of about 5K. If I crossover the tweeter at, say, 4K, in parallel with the woofer, will it put any extra load on the amp? What if the crossover point is lower for the tweeter (still full-range on woofer)?
