So far, there are some amazing ideas for these Epique drivers! Here is what I came up with. Feel free to critique it if you see something wrong. I went with two of the 5 1/2″ drivers in a 0.75 cubic foot box tuned to 39Hz. This gives an F3 of 35Hz (very similar to the DINAS).
This would result in an enclosure that would be approximately 7.5″ wide, by 30″ Tall and 10″ deep (before port). The port would be approximately 6″ wide by 2″ tall and 25.25″ long.
If you gave this speaker 200watts, the SPL would be about 108db anechoically 3 feet away. With 150watts, it only drops about 1db. Even at 10 feet away, you still get an anechoic SPL of 98db. which should be more than loud enough for most people.
The port velocity at 200watss is around 19m/s. Assuming a rear firing port this shouldn’t be an issue. But if you think it would be, at 150watts, it drops to 16m/s.
Assuming you are using gear with a built in 20hz high pass. The speakers are completely protected from over excursion at 15watts. They do go over at 200w between 28hertz and 17hertz.
Overall, it feels like a good compromise between high output and port velocity. The only thing that is somewhat of a concern is the first port resonance it relatively low at 226hertz. It would be nicer if it could be pushed up higher. But I am going on a limb and guessing that will not be much of an issue.
It would seem if you want maximum output out of these, it would be best to go with some sort of passive radiator. But I don’t think that is a great option currently. They either wouldn’t match aesthetically or you would end up using a much bigger passive radiator, that would surely look pretty silly.
