16 gauge is fine for your system. The Duelund will simply sound more open, resolving and real. The WE 10 gauge will be warmer and not as open or resolving. The WE bass is slower and not as fast and crisp. You can try both for yourself in your own system to see which one is best for you. Both are very good indeed.
You should also know Dueland is available in 12 gauge. Also I understand authentic WE hasn't been manufactured for quite a few years now and there are a few unscrupulous eBay sellers claiming to have WE but "caveat emptor".
