I tried a few 6.5 and 8 inch that I had on the shelf - even some Saba green cones. Ended up with an old VOM (Phillips?) fullrange. Gave the speakers to a friend when I moved, he still has them and loves them.

Hard to say what to pick without going crazy in cost. I have some FaitalPro drivers that might work - but haven't ever tried them in the Manzie. Others here will certainly have some suggestions.

That's going to depend on the horn. Since you'll be crossing circa 700 Hz, you'll need a big horn.

I would suspect that the second GRS might be better used as part of a 2.5 way configuration, low-passing it in at half the existing crossover freq or so. You could also deepen the wings on the bottom GRS. The interaction with OB cancelation would be the focus. Not an utterly simple adventure.

Default Dual Woofer Manzanita Ultra

Second try.... I did design and build a dual woofer commercial Manzanita Ultra from 2012-2017. Model Manzanita Ultra Plus! It utilized a Seas Prestige 8 inch full range, P/N FA22RCZ. (Seas H1597-08) As Skip Pack discussed in his post, not an easy design to get right. The crossover used 14 component parts. The Ultra Plus performed well, both as an Audiophile and home theater speaker..... but did not sell well primarily due to its size. The Seas 8" is still available from Madisound and others. Will try to post a picture in a separate post. J

I did use some Wild Burro prototypes, can't remember if 8" or 6.5" They worked well.

Could you please let me know the mechanical power handling of the speakers in watts/channel? Does this power handling figure depend on the thermal rating quoted by the manufacturer, or is it totally independent in an open baffle?

Sujat.. Your question is a good one... However, there are so many variables... in the pro audio world, power dissipation is quite important... but in a residential hi fi Open baffle application it is of little value. Most open air, lightly loaded woofers can be driven to Xmax with as little as 15 watts. So, as you postulate, the electrical dissipation quoted by the manufacturer means very little in an OB application.
