Siblings in Paradigm's Premier series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Paradigm 700F digs deeper - 45Hz against 49Hz. A subwoofer would even that out. |
| Amplifier needs | A | Paradigm Premier 620C v2 is more sensitive (93dB vs 91dB), so it goes louder on the same amplifier. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Type | depends | A Passive Center Channel against a Passive Floor-standing - a different job rather than a better one. |
| Cabinet | depends | Passive Radiator vs Ported. |
| Expandability | B | Paradigm 700F: bi-amping. |
| Price | A | Paradigm Premier 620C v2 is cheaper - $1,300 against $1,700, about 24% less. |
A Paradigm Premier 620C v2 B Paradigm 700F
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Paradigm 700F measures better, Paradigm Premier 620C v2 costs about about 31% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If your amplifier is modest, vintage or valve-based, Paradigm Premier 620C v2 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
