Hi
After being left disappointed by my svs pc13 ultra I'm going infinite baffle. I have a pair of FI IB3 15 drivers and am about to order the amp: Extreme 1000 I know the site says you can only pre order but bk have told me they can have one shipped in a couple of days!!!! There's just one thing, they've put a HP filter at 15 hz/ 24 db but say it can be moved within reason. I have modeled the system on winisd but I get the best curve for Xmas with 1000 watts and a 9hz/24db filter in place. This is the first time I've done anything like this and only have my own research to go off so a second opinion would be most reassuring. Also would I be right in thinking that a 24 db filter is fourth order?
Here's the driver info: Two 15" drivers each with a single 2 ohm voice coil that will be wired in series for a 4 ohm load
Fs: 22.7 Hz
Re: 1.5 Ohms/coil
Qms: 4.30
Qes: .74
Qts: .63
Mms: 247g
Sd: 810cm^2
Vas: 183.3 l
Spl: 86.4dB 1W/1m
Bl: 8.43 N/A
Xmax: 30mm
Rms: 550W @ 20Hz
Any help will be much appreciated.
Thanks.
Rob
