Default Better frequency response?

Hi folks!

Currently I want to build a Onken enclosure speaker and I have trouble to choosing a right LF speaker driver. I think still I can't "read" frequency response characteristics of loudspeakers properly. Here I share some of them with you:
1. Click the image to open in full size.
2. Click the image to open in full size.
3. Click the image to open in full size.
4. Click the image to open in full size.

In my opinion second driver is the best, then first, third and fourth.

What do you think and what else can you recommend to me?

Thank you!

Looks like first one already has a crossover applied.
When you look at frequency response, look at rising impedance curve also.
FR may seem flat, in fact it is attenuated with high inductance of a woofer.
Best hi-fi woofers have almost flat impedance curve and very little rise in FR.
The lower you cross-over the less relevant these curves are.

Thank you MisterTwister!
First graph was from russian speakers datasheet. In my country they are quite cheap.

It's my first time that I want built something serious. Thats why I don't want to waste my money. I will try first. So I'm looking for affordable loudspeakers. And it's really hard to find something suitable.

Which woofer you know with the flat impedance curve for example?

Ones with flat impedance are never affordable.
SB Acoustics :: 6 1/2'' SATORI MW16P-8
Zaph|Audio has a lot of woofers tested
I don't trust that first curve. If it is true, you can't go wrong buying this woofer.
