 No. That near field response doesn't apear to be very......good  Take a new one, this time with the mic or spl meter about 4" back from the center of the driver with a folded up blanket, some pillows, or anything else thick and absorbent behind the mic/meter. You should end up with a very deliberate, smooth, predicatble FR. See attached for a close mic measurement of my ported sub to get an idea of the type of smoothness you should be getting. |
Thanks, I will do that.
What do you think of using 2 of the new FI IB18 subs in a 100cu/ft enclosure?? I may use a room beside my theater and build a large enclosure....I was thinking 95-100cu.ft 12" Port 13" Long for a 12 hz tune. $200 with all that excursion might be hard to pass up.
