Default Bass boosted preamp, suggestions pls...

Hi all,

I've newly designed a preamp for my LM3886 gainclone;

Its a bass boosted preamp. It has ~9.5dB gain 100Hz to 100Khz band and increasing until 20Hz with a logaritmic slope. At this point, it has ~15.5dB. That means I have extra 6dB gain at 20-30Hz band. Thats exactly what I need. Because my speakers have -6dB @ 30Hz point (Wharfedale Diamond 9.6).
This is the frequency response which Spice simulates;

What can you say about that? May you give some advices pls...

PS: The frequency response is on the top. The other is phase response)
