crossovers

I find that electronic crossovers often have more coloration than passive ones, assuming both are properly designed.

Passive crossovers might seem to rob the speaker of a certain immediacy at lower volumes, but at higher volumes (and not that much higher) they allow the speaker to be smoother and more transparent.

No worries at all that the Onken bass can go that high. It can go much higher. 500Hz is an easy crossover point that allows the coloration of caps in the crossover to be minimal while also keeping all the drivers well within comfortable limits. One thing that arises out of this is that since the bass unit is going that high, there's no need for a larger main driver and the addending slower speed that the larger cones tend to have. So you could run a 6" unit and have a faster more involving midrange.

I won't dispute your claims about passive vs electronic crossovers. I will add the following to the discussion though.

Electronic crossovers allow you to change the relative output of different drivers depending on how the music was mastered or recorded on the particular playback medium. Each musical piece is recorded differently, although most are within some reasonable margin. But an appreciable number of recordings require some significant adjustments, particularly in deep bass.

I would say that at the very least, allow for controlling the output of the subwoofer separate from other speaker drivers. But I can separately control the midbass, low midrange (60 to 500 hz) separate from the subwoofer and high frequencies and this is useful. The high frequencies of my system (> 500 hz0 are passively cross-overed.

I use the Sublime Acoustics crossover, which seems transparent.

What do you consider a large room?

  My old listening space was 17' by 21' and most 'full range' single-driver loudspeakers would fall flat on their face trying to fill it at a a decent level.
  
  The reason to go with a 'full range driver' is efficiency.

    Thanks Ralph. I use the 8" PHY-HP with the super tweeter and a REL sub in a 13 x 21 room. Acoustic jazz at moderate volumes. It has served me well but I will try a Cornwall IV at some point.

Hmm ...Then I will use the Phy-HP in a small room.

I think Ciuffoli high efficiency design pretty much follow your trend
