Uprading Infinity TSS-450 fronts

I've got Infinity TSS-450 now, the fronts are a bit wimpy and lack mid-range. Would it be a good idea to replace them with something a bit better? My budget is a bit small, so I considered the Yamaha NS-M125P. My receiver is a Yamaha HTR-6030.


Are there any other speakers I should look at for a similar size and price? Width is my main concern, as they must fit on the desk.


I would like to know if anyone else has them and what they think of them.


Thanks for taking a look.
