Infinite baffle

I saw an ad a while back for some 12" subwoofers. They seemed econoimical and appeared to be well made. The ad made a remark about them being the best bang for the buck for infinite baffle system. I think they were $100 each. I did a little research and found the subs to have a considerable amount of controversy over the price and quality. I wish I could remember them. Hoping someone here may be able to refresh my memory.
Sorry for my lengthy intro. I would like to put 2 or 4 12" subwoofers in a wall downstairs. It is an unfinished basement. I would like some hints or suggestions to get my research started. I can't spend a ton of money but would like something above common average.
It is my understanding that infinite baffle refers to in wall subs.
Thanks
 
'In wall' in the sense that there will be a room size cavity on the other side to load the driver. Typically, IB 'sub' drivers have a <20 Hz Fs, >0.5 Qts and a large Vas relative to the driver size.

There's quite a selection of sealed/IB 'sub' drivers, so no way to know what brand/model you're referring to.

FYI, all 'things' IB can be found here: Home | "Cult of the Infinitely Baffled" Hear The Bass, Not The Box The definitive online resource for Infinite Baffle subwoofer design Established 1999

SIM 6 of these bad boys in winisd pro. You can see my manifold below. These drivers are the GRS 12sw-4 on PE. They are a gem and only $20 each. I can't believe more people don't use these!
