In this review, we will be comparing T 7x and DB4S, two Powered Subwoofer speakers from REL and Bowers Wilkins. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of REL T 7x and B&W DB4S first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the REL T 7x and B&W DB4S compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.
