Hi Kyle
 
What in your opinion would be a decent tapped horn, the cyclops maby? I am also looking to get a few cabs made around the similar driver.

Almost everything goes down to 30Hz. It depends on the actual power output it delivers at this frequency.
Nikon and Canon people should not be married to each other. Why did you let this happen?

according to the sims i have seen/afaik/remember, the regular cyclops are not tuned very low.. around 50hz.. the extended version propably rather 40ish hz, keystone regular around 45hz, extended about 35hz?

Cyclop, TH118, Keystone, all not very big boxes, so 40hz real output with a -3db point at 35ish HZ is what you realistically get from them.
For real 30hz performance, you should look at something like the OT horn or similar design.
Bigger boxes needed for sure, so it is all a compromise.
Once you start thinking truck pack, things get complicated fast.

I am not so experienced as you guys here but if 30hz is needed wouldn't band pass cabs be better to use, maby X1?

Better is also very broad term. It gives out great SPL for one box, but has also many disadvantages.

Standard Cyclops has 40hz with Fane Prime even though Staip said 45.  Has a very reflex sound.

Not an enjoyable build, think about getting bracing in, need a carpenters mind, or one better than mine :)

Very high attack and subby cab though. Only time I have ever liked sound of non reflex cab in small space

Sadly the FSP link is broken. Link below (the builder) was me.
