+1 csmgolf. "they can be the icing on the cake for a well sorted out system."
If your speakers have bass limitations maybe getting the most out of them still won’t make you happy. I have speakers that have twin 7" bass drivers and they are rated to 30hz +/- 3db. They go lower that that with rolloff increasing. Bass is very good and adequately low but still not chest pounding that only a larger driver can do. My speakers are also in a much higher price tier than the speakers in question here, but the bass capability is indeed there.
I also, like mtrot, use the Cerious Technology Graphene Extreme speaker cables and agree that these are one of the better cables out there that clearly have allowed the bass potential of my speakers to be unleashed. Prior <$500 cables were good, but the CTs were a huge jump in performance. I’ve been historically frugal but these changed my thinking, enough to know what can be achieved.
The point here is that cables don’t make bass, rather they permit whatever is possible to come forth. Great cables do make a difference, but I still would not spend a disproportionate amount on cables based on the speaker price. Maybe 10-20% of the speaker price for cables is certainly warranted however as component investments go.
Cerious Technologies just launched their new price-no-object (still not ridiculous) line of cables that early upgraders are saying is worth the jump. For my system the price would still fall in the 10-20% range of my speakers. I am tempted to eek out that last bit of bass. One of the early upgraders has my speakers and is raving that the bass is even stronger, deeper sounding (not in actual measurement - that’s not possible), and better controlled than before. For me, I will probably pull that trigger when funds are available. My system is built around the speakers, so getting the most out of them is worth it to me.
