Sonic Characteristics and Merits of Polk Monitor 70
The Polk Monitor 70 does give you a sense of confidence that it could produce powerful sound and shakes the room with its bass. Taking off the speaker grille, you will see a 1″ (25mm) Dynamic Balance dome tweeter located above the larger drivers which are four Dynamic Balance mid/woofers. Below the rest of the speaker drivers, you will spot a front-firing bass port which is quite large. With the bass port situated at the front, it does give us the convenience to bring the Monitor 70s slightly closer to the rear walls.
Without the speaker grille on, the Polk Monitor 70 doesn’t look like your average budget floor-standing speakers, and to be honest, we got high hopes for them. The frequency response also made them look promising, it is at 40Hz-24kHz (-3dB). The nominal impedance of the Monitor 70 is 8 Ohms and has a speaker sensitivity of 90dB which is cool as it shows they are quite easy to drive. But when we look at their peak power handling of up to 275 Watts, the does indicate the Polk Monitor 70 floor-standing speakers will do better with receivers that have higher power outputs. Adding an active subwoofer into the mix will still be an option.

The overall sound reproduction is clean and there are plenty of details to boot. The level of clarity is high as well but can be overly bright sounding especially at higher volume levels. It is wise not to match with receivers that might excite the Polk Monitor 70 treble by too much as it can make them sound harsh. Still, for listeners who are used to bright-sounding speakers, the Monitor 70 shouldn’t be an issue. The imaging of this pair of floor-standing speakers is excellent and also they can go really loud which is fantastic for home theater use.
The soundstage is wide but unable to really keep its focus when the scenes or music starts to get busy/complex. It is still considered stable for entry-level floor-standing speakers though. The dynamics of the Polk Monitor 70 do help to deliver a pretty engaging music presentation. We also love the energy the Polk Audio speakers bring during the movies’ action scenes. There are well-placed solid punches and the bass performance is agile for a floor-standing speaker at this price range. The deep bass reproduction has weight to it and does help to build a strong presence. Adding an active subwoofer is recommended to supplement the subterranean bass reproductions, setting the crossover to 60Hz would be sufficient.
All in all, the Polk Monitor 70 is an entertaining performer and does its job really well in a home theater setting. For music, it is still quite enjoyable to listen to them. They are bright-sounding speakers but don’t reach a level of cringe even at high volume levels. The midrange performance of the Polk Monitor 70 speakers is kind of lacking, not to mention, it is outshined by the highs and low-end reproduction.
