I would consider the comparison of the Calibre to the Profile to be the inverse of what would be expected typically in comparison of a bookshelf speaker to a tower speaker. A breakdown of these two could be instructive.
The Profile is said by Joseph Audio to provide a "broad, deep sonic landscape", is 39" tall (imo not taller than a bookshelf on a stand), and weighs 47 pounds. Not much of a floor stander, imo. The broad and deep description should not be understood as affecting the frequency spectrum, i.e. lower bass. Fancy words can lead people to expectations that may not be fulfilled. I have nothing against Joseph Audio in regards to this; I would analyze any speaker company’s product similarly.
As for the Calibre, it comes with internal amplification - the Calibre XD active which is about 7.5K. So, there is no equivalency between these speakers for a distinct reason. With the Legacy speaker one gets amplification in the deal as well, versus having to spend for amplification for the Joseph Audio speaker. Note that the specs are nearly identical for the Calibre and the Joesph Audio. Ergo, one gets what I would call marginal benefit in terms of specs in moving to the Profile, considering that the Pulsar is 42dB. However, I would expect the Puslar to be holistically supeirior to the Profile across the frequency spectrum. The difference in frequency response between the Calibre and the Signature SE is 16dB, a veritable rift valley of deeper sound. The Calibre XD weighs more than the Profile.
I encourage all audiophiles to learn to understand frequency response specs, as this WILL dictate the experience regardless of the brand and model of speaker selected. Also, generally, the size of drivers has a pervasive influence upon the sense of ease of a speaker’s sound, the larger the drivers typically yielding a more relaxed sound at higher listening levels. Some audiophiles are sensitive to this and others less so.
