Both to be sure.First you will not be able to experiment with speaker placement and second the enclosure has a great deal to do with the speakers overall sound.The quality of a regular speakers cabinet has a lot to do with its sound.Let me ask you a question,will you be hanging these yourself or will you hire a professional installer?
Are there any high end audio shops in your area? Sometimes they will have some used gear on hand that you can see.I would still stay away from inwalls,start with fronts until you get some more cash and build from there,you won't be getting surround sound now but over time you will have a much more enjoyable system.
