Cubo Kick 12 cheaper alternative driver

Hi, i have recebtly built a 3 way 12v sound system and would now like to look into building 2x Cubo Kick 12's. I would like to find some drivers for it that are a bit cheaper than either of the 3 suggested drivers. Ideally id like to spend no more than £80 per driver. 

Im not quite sure what TS parameters i need to match more than other parameters. Or if there is anything else i should be looking out for??

So far i have seen these 2 drivers which to me seem good but would like someone to clarify. Again, i am new to this so forgive me if im wrong.

Or

Surely someone out there has had success with some cheaper drivers and/or can point me in the right direction.

Thanks in advance

After some more searching i just noticed that Blue Aran has a TS parameter matching tab. So from the Faital Pro 12FH500 i found these Beyma 12WRS400 which seem to me match up pretty close. Also at £81 each is a good chunk less.

Id still be interested in people opinions though or if anyone has any other suggestions would be great.

Also incase it helps, they would be linked in parralel and bridged to the amp so each driver would recieve 150w rms
