Open baffle with Philips AD 3800M and AD3460AM

[RainV]

i am just trying to make an ob speaker for my hiohm philips otl amp with EL 86.
in addition to the sprakers i habe two 2x12 active subwoovers, so bass is no problem.
Cause both speakers are fullrange i wonder if i should let run them just in parallel. The 3460 has a high tone conus inside. The 3800 not. The AD3460 AM runs fine alone as well, butin the lower midvrange the AD3800 M has more volume.
Does anyone know if it would be better to use just one speaker, e.g. an AD3800 AM which has a high conus as well. Is its performance in the highs significantly better than the AD3800M without the additional little conus?

Not familiar with those drivers but it is almost never a good idea to run high frequencies to two drivers. At minimum wire them in series with a capacitor across the terminals of one of them. That way they will share the bass load but only one will play high frequencies.
