Horizontal vs Vertical biamping

For me horizontal is the best but in order to realize the full benefits, an active crossover should be use. Vertical was only slightly better than using a single amplifier. Horizontal is a big improvement and you can use a much more powerful amplifier for the bass region. I’ve been multi-amping for over 40 years and would not do it any other way.

It seems that the crowd is pushing you towards active electronic crossover 😀. They are right. Look into it, and when ready, give it a try. It’s worth the trouble. It will be an eye opener. 

Spenav you got that right. Overwhelming the support for active crossover. I may need to find an active crossover guru opening up those speakers is not something I am currently comfortable with. Whew. 

I got you. Take your time. Read up about it. It is actually simpler than it sounds. In your case, you can get good results using a two-way xover and leave the mid and high frequency drivers connected to the passive crossover. Look into Marchant crossover. I have had excellent results with them in the past. Sorry I opened this can of worms 😀. 

Spenav No worries and thank you for your input. I will see what I can learn about active xover systems.
