15 inch bl makeing slapping noise

[doogie 0]

i have just bought two 15 fi bl's daul 2 used on cl. i knew one was going to need a recone so am planning on doing both. I'm running a mtx 81000d to one in a ported box i threw together just to see what each one sounded like box is little over 3 1/2 cubes, an tuned at 32. i get a clipping/slapping sound from the speaker when i turn my gain up past 1/2 way with the vol turned up on the head unit. an (h.u. settings are flat). question:

could i just be clipping it?

does anyone else get a leed noise?

how can i tell what year it is for recone purpose?

Thank you for your help any thing i may have left just ask

DOnt turn your gain past 1/2 then. did you set it with a DMM?

slapping yould be your box also.

Are the leads integrated in between the spiders or loose off of the cone? What is the subsonic filter set to? How much excursion are you getting out of the subs? Can you post a side shot of the sub so that we can tell which model it is?

Thanks,
