Cubo 18

The SRX4718 will likely be able to be crossed higher, the Cubo 18 will be louder and looking at the specifications of the SRX4718 it will go just as deep.
I think wether you'll put it in a SRX4718 or Cubo 18 it will sound well.

Thank you sir.
In the cubo 18, where do you recommend crossing it over at? Im looking for somewhere between the 120 - 150hz

Personally I wouldn't recommend any 18" sub to be crossed higher then 125 Hz. They might excist, I just never heard any that sounded right that high. If you insist on crossing above 120 Hz-ish, I would strongly recommend using a basreflex.

Best crossover frequency for most 18" cabinets is in between 80 and 100 Hz imho. This is however driver dependant as different T/S-parameters (and such) produce different acceptible results.

I've added the measurements for the third prototype for the 18LW1400 and the V18-1000 vs Cubo 15 and the 18LW1400 in a reflex cabinet as stated per plans. The third prototype is 7.4 liter larger externally and has a slightly different chamber and horn length.

I've posted these measurements as it's not likely I will be building Cubo 18 any time soon.
