That Xmax is small. 12mm? They should sound good though.https://www.sonicelectronix.com/item-105465-NVX-VSW122v2-VSW122-v2.html
On sale and close to your budget. Good budget option for both your price range and power (500RMS at 4 ohms). Have heard 2 different vechiles with this sub and for almost sub $100 it's not bad at all.
