Bowers & Wilkins Australia is currently running a 'Trade in, Trade Up' offer where purchasers of a wide range of B&W models are offered a minimum Trade In amount for old, working gear.

The offer covers the all-new 600 Series, the 700 Series and the flagship 800 Series, as well as the PX NC headphones, Mini Theatre systems and subwoofers. The fixed Trade In return varies depending on the model purchased (the quality of the traded-in gear has no effect on the amounts), and it varies from $55 back when purchasing the PX heapedhones up to $4190 if you're buying a pair of 800 D3 speakers. The full list of eligible products and the trade-in amounts can be seen here.

Now there's a bonus offer over and above the trade-in cash back for those purchasing either floorstanding speakers or a DB range subwoofer. Until August 9 (or while stocks last), B&W is giving upgraders a bonus T7 Wireless Speaker.

That's quite the bonus, as not only does it carry a $499 RRP, it's a lovely little wireless speaker. You can read our full review here, in which we concluded: "It’s a premium portable through and through. The arrival of the new Formation series may see the T7 ends its run in the company's lines fairly soon, but not for any reason of being out of date or irrelevant; it's a great little player. We simply loved the T7 Wireless."

Meanwhile full details of the Trade-In deal is on B&W's special website (go to the ‘Participating Stores’ tab to find the dealer nearest you to access this offer):
