Yes, of course, it is better to have all the drivers in the same direction. It is even more important with those with Wedgies, Super Vs, Serenity 7s, Hawthorne open baffle speakers, etc. that cross over higher in frequency. And just as important in these same speakers would be to physically align the voice coils of the main speakers to the woofers. By having both (or all three) woofs all facing forward and physically aligned with the main speakers the sound will be tremendously better. Also having no H-frames but using straight baffles or U-frames would also make the sound better. Why would you want the lower midrange to come out of some square tubes? Serious resonance problems there. If you cross the woofers in at 70 or below then the H-frame is probably doing no damage.....but above that frequency? You have to be kidding!!!!!! Seriously bad!!!! You guys with Wedgies, Super Vs, Serenity 7s, Hawthornes...need to turn off the upper drivers and listen to the woofers by themselves....you will hear voices, all kinds of midrange sounds....these things are only crossed over at 12 db per octave.....they go way up in the lower midrange.........the speakers need to be open to blend perfectly with the higher frequency drivers....not stuffed back in square tubes. Think about it. Try it!!!!!!!! I would never ever use H-frames above 70hz....never. And having the drivers face different directions....this is just plain wrong. And every speaker I have ever built sounds best with the woofers and the upper drivers physically voice coil aligned.
