Well, I would advise you do not order any horns with aiming 2490. Get the drivers first and order the horns AFTER you feel that the driver satisfy you. The fact that the loaded driver can hit 300Hz does not mean a lot. You need to like the sound of the driver at 300hz not juts acoustic pressure it creates.

Sure, I'm going to try it in JBL 2352 horn first. I also would like to share predicted SPL of my 42Hz horn with Supravox 285-2000 EXC at 12V:

And 9V:

The idea is to highpass next channel at 500-600hz and if it is flat down to 300hz, I have around -6db at 250-300hz and it is good match with predicted SPL of upper bass. Romy, can you, please, share your thoughts about 2490 ? I read thread here and you didn't rise any conclusion. And have you had any experience with other 4" JBL drivers 24XX ?And can you point to what aspects of sound I need to pay attention during evaluation of 300-500 range ?Too much questions as usually SmileThank you!
