The PB-12NSD is a great choice!! A little expensive for the performance but nontheless your getting a quality driver, great enclosure & solid performance with SVS. This new sub WILL transform your listening experience for sure!!! You may find the rest of the system cant quite keep up with the NSD but thats ok your starting somewhere
Please come back & let us know your thoughts on it & post some pics of the new sub & the rest of your setup.
Make sure you do the "bass crawl" to locate the best placement location for your sub!! Placement makes ALL THE DIFFERENCE with how it sounds. Also, the sub is going to need a solid 30-50hrs of break-in time. The sub wont sound its best right out of the box. No it will take some time for her to loosen up. You will notice deeper, smoother bass as you use her.
Congrats & ENJOY!!!
