Unsatisfied with the extension, or the output? Flat to 25 Hz and -4 dB at 20 Hz is great extension. If you're used to +6 or +10 dB at 30-40 Hz as 'normal', a vented system will be your cup of tea. In this era of 130 dB car woofers and THX certified theaters that are -10 dB at 20 Hz but +10 dB at 40 Hz, few people have heard accurate bass.
I don't want to jump to conclusions about your tastes or experiences, but have you measured the in-room response of your sub? Designing for flat anechoic response will give you a grossly boosted in-room response below 40 hz.
