What Box for those drivers?

Hello, hope this is the right place to ask this.

I found some old decrepit speakers in a shed, the bass reflex cabinets are huge and in a gruesome condition but the drivers were protected and are in a splendid condition. So I just got the board with the drivers and took them home. At home I tested the drivers and they work.

Included a picture of the magnet for identification purposes as well as a datasheet i found. According to someone in a forum they measure (avg) like this :

Phillips(Belgium) 12202/M8

Re.........7.49 Ohms

Fs........43.74 Hz

Qts........0.456

Qes........0.55

Qms........2.665

Le..........0.189 mH (10k)

Mms.......35.19 g

Vas........135.7 L

This kinda tickles my fancy so I wanna try to build my first selfmade hifi speakers with them if that is possible. Got lots of wood foam etc laying around.

The drivers are in very good condition and according to some folks in the Internet they sound pretty good but are geared mainly as midwoofer, which i noted in testing as well,as the bass is very lackluster. That makes me biassed towards throwing them in some kind of backloaded Horn speaker with an external horn tweeter to get the most of of them. But yeah, what do I know, the only speakers I've build until now are for PA purposes and hifi speakers for inside a room or even designing own cabinets are different beasts. So maybe you can help me:

What kind of speaker would you throw them into, are there plans I could utilize that would fit this thing?

Thanks in advance!
