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. Mike

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?

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.

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. https://forum.speakerplans.com/beware-the-one-eyed-monster_topic39393.html Edited by nickyburnell - 12 January 2018 at 8:15am |

Hello I know this may be late but did you make the box yourself. Cause I am also interested in the driver and I am looking for the best of both worlds that is the best sound with the smallest possible size and weight. That's why I like your box. Please if you didn't build it yourself who did. I am based in Maryland and have been trying to get a good box builder. Any help will be appreciated
