Apex 120, or 125?

Alright, I know these aren't great mics by any means, but I'm very limited here and I don't want to shell out a ton of money on a D112 or Beta 52. These two mics are kick drum mics. My local store has the 120, so I'm just wondering if it's pretty much just as decent as the 125. Here are the specs:

APEX 125:
* Type: High SPL Instrument
* Element/Capsule: Moving Coil Dynamic
* Output Impedance: 50 Ohms
* Frequency Range: 50-16000Hz
* Pollar Pattern: Hypercardioid
* Sensitivity: -84dB
* S/N Ratio: >65dB
* Maximum Input SPL: 165dB
* Connector: Integrated 3 pin XLR-M
* Dimensions: 65mm x 109mm
* Included Accessories: Integrated Mic Clip

APEX 120:
# Type: High SPL Instrument
# Element/Capsule: Moving Coil Dynamic
# Frequency Range: 50-18000Hz
# Pollar Patterns: Hypercardioid
# Sensitivity: -74dB
# S/N Ration: >65dB
# Maximum Input SPL: 130dB
# Connector Integrated: 3 pin XLR-M
# Dimensions: 39.5mm x 130mm
# Included Accessories: Integrated Mic Clip

Is there really much difference?

Alright, been looking at freq. responses for various popular kick mics. The Beta 52, the D112, ATM 25, Audix D4, etc etc. The 52 and D112 go as low as 20Hz, the rest are either 38-40-ish.

I'm probably remembering incorrectly, but doesn't the human ear not really hear below 40hz? Or is it 20Hz? I'm just wondering what differs some of these mics from a 57 for example. Why should I buy one of these Apex's for example, when the 57 has a wider frequency response? I know I'm missing something here.

I believe its 20hz, but the frequencys below that play a big part in the 'feel' of the music, not necassarily the sound. You may not be able to hear 10hz but you can feel it in your chest.
