I have 1.5s as well. This can be a difficult thread since expectations on bass could be different. I really like this speaker and satisified with the bass as well as other qualities. Room size and placement are considerations and I am sure you have tried moving them around. I think with this speaker as well as other Proacs, you need allot of current from your amp. I think some people might be dissappointed with this speaker because they are not driving them with the right amplifier. I think Proac came out with the D15 replacement for the 1.5 because it can be marketed to a broader audience ( consistent bass performance from a broad set of equipment). I am using Rogue Audio 120 Magnums and I'll tell you the bass is tight and satisfying (ultrinear more bloom, fuller; triode tighter and more tuneful). Some thin sounding solid state gear or low power tubes will not cut for this speaker.
I am not sure of your electronics but I would look to that direction as better alternative to a sub. Again I really like this speaker.
Personally I would not advise a sub with this speaker. If for any reason (besides difficulty in integrating) for what a good sub would cost I would get another speaker or look to other electronics.
