It's an illusion.
The slot is centred.
It is just an experiment; this weekend, I'll replace these with full height 1 by 10s.

Hi Pengesluk,

sorry, just noticed your post right now.
If you intend to use a Fertin38ex and a Raal, I cant help but imaging that a Fertin or EMS fullrange for the mids would be a better match. Compared several 8 inch drivers on my journey and have finally chosen the Fertin 21M8EX as main driver.
A modular approach is a good idea to try several drivers, but of course each driver will need its own alignments.

All the best

Default Mini-Ks With Open Baffle Bass

Posting this here as well the Mini Karlsonator thread.

I built some open baffles to experiment with adding more low end to my system this weekend. Theyre roughly based on John Buschs Manzanitas in terms of the GRS15 woofers, baffle size and wings and the 20mH inductor on the XO. I have an 8 Ohm mills resistor in series with the 0.53x Mini-k with dual 3fe25s. I like what Im hearing so far. They blend pretty well and give the low end I was missing along with some good punch on percussion. I think the woofers still need some break-in time to loosen up the surrounds and things will get even better. Maybe some more XO experimentation later this week too.
