Fi Bl 15

[holdterry]

I wondered if the flatwind coil hurts sq and or is what is referred to as prone to peaking just a over all increase in output? Box is 4.08 net 3.25 tuned 31-32 Hz. I thought I would get the chamfer and flatwind coil = sub's stock RMS rating is 1500 and replacing SXX 15 2010 model because I sold it, and old box tuned a little too high for me and wanted something new.

Power amp big 3 - electrical seems OK stays above 13.5-14 volts, just first time ordering a sub with options and this is what I have to spend, so flatwind coil or not, used daily, but from what little I seen of subs they seem pretty beefy even stock. Of course gain set right all that I foresee no issue, like a descent sq and spl together if possible. If off base, guess better to know before pulling the trigger on a new sub.

Believe specs on sub box in car now is as follows:

Width: 25"

Depth: 21 1/2"

Height: 16 1/2"

Gross Airspace: 4.12 Cu.Ft.

Net Airspace: 3.5 Cu.Ft.

Port Dimensions: 15" X 2 1/2" X 28 3/4"

Port Volume: .62 Cu.Ft. Net 3.29

WELL MEASURED AREA LOOKING AT THE Bl 18 instead, son's other box after port and displacement has a net 5.29.
