Both models are covered in detail on their own pages. This comparison isolates the differences that change a buying decision — published specifications, the role each plays in a system, and the room situations where one makes more sense than the other.
Both are Signature Elite floorstanders with the same tweeter and the same 6.5-inch woofer design. The ES60 adds a third woofer and a taller cabinet, which extends low-frequency capability and raises the power the pair can absorb. Neither is a general upgrade over the other — the room, the listening distance, the amplification and the rest of the system decide which fits.
Both are floorstanding front left/right models intended for the same position in a system, so they can be swapped without changing the layout, the channel count or the receiver configuration. Both are passive speakers requiring an amplified channel, both benefit from the same placement discipline, and both should be tonally matched to the rest of the front stage.
Both are Signature Elite floorstanders with the same tweeter and the same 6.5-inch woofer design. The ES60 adds a third woofer and a taller cabinet, which extends low-frequency capability and raises the power the pair can absorb. In a room where the speakers can stand clear of the walls and the seats are a reasonable distance away, that extra cone area is audible as effortlessness at higher levels rather than as more bass.

These are situations where this model is the easier one to make work well, not a verdict on quality.
The same logic in reverse — room, layout and system context, not ranking.
Whichever model is chosen, the outcome depends on the same work: matching the centre channel to the front stage, placing the subwoofer by measurement, setting distances, levels and crossovers, running room correction and confirming by ear. We plan cable routes and speaker positions before carpentry wherever the room is still under construction. See the Polk installation process and Polk speaker placement guide for the full sequence.
Specifications on this page are taken from Polk Audio's own published product information and are re-checked before each content update. Where a value is not published by the manufacturer, we leave it out rather than estimate it — you will see "Specification currently being verified" instead of a guessed number.

They are different fits rather than steps on a ladder. A larger cabinet in a room that cannot accommodate it will perform worse than a smaller one that is placed and calibrated properly.
Yes, provided the front left, centre and right stay within one family. Using one model as fronts and the other as surrounds is a common and sensible arrangement when both are from the same range.
Usually the smaller of the two, because placement freedom and listening distance limit what a larger cabinet can deliver. We confirm this against the actual room dimensions and seating position before advising.
Not in a correctly set-up system. With a subwoofer crossed over at the right point, the audible difference shifts toward how effortless each pair sounds at higher levels rather than how much bass is present.
Share the room dimensions, seating position, ceiling type and how the room is used. We map that to a configuration and speaker roles, and both LiveInSmart experience centres let you hear layout differences before committing.
