I have experimented through the years with adding high quality subs to systems that already seem to have sufficient bass. In most cases I found that not only does the bass improve, but there seems to be a 'lifting -of-the veil' so to speak in the other octaves as well. I have spent some time with the JL subs (mentioned above) along with other high-end offerings. I can't help but think that the right balance of Sasha 1 and the JLs could result in something pretty special, albeit that it would take some patience to get the crossover and sub placement just right to make it all come together.
