Good question.
The nice thing about vented boxes is the added efficiency above and below tuning can really take advantage of high compliance suspensions. When matched with high displacement motor capabilities you can displace a TON of air without much power.
In this case you can get the driver in the A3-300 to full excursion with just 300 watts. No reason to burn the extra power if you don't need it. Given the extension requirements and needs of the A3-300 it's just not needed to use the bigger amp.
The nice thing about the A3-300 is it's phenomenal in terms of efficiency, output, and low frequency extension. It's downfall is the size of the box. If your ok with that. No reason to use more power.
If you want a smaller box. Use more power. Thus the 500w makes sense and that's where a sealed box comes in. I heard something about a platform in the shop that works well in that application but for the big output with low cost when box size isn't a concern more power is just a way to increase cost. Not performance. Concentrate on driver engineering instead of adding power for the sake of just adding power and you get great results.
It's like a way of increasing gas mileage and acceleration without increasing cost. You can put in a bigger engine in but the gas mileage will be worse and the car gets heavier. There's a point of diminishing returns.
When subwoofers are designed for small sealed boxes and done so well you can drop them into mid sized vented boxes tuned low and get unbelievable results. Your wife may not love how it looks tho
