I had them up against the BX8s, some Truths (terrible), tannoys, and the yammys.
I'll take the behringer truths right out the equation before I start. The tannoy reveals had a good midrange balance, the Yams were very crisp and the BX8's I thought (to my ears) were the most hyped of all. The wharfedales were the most neutral sounding to my ears and my choice to buy that day.
Personaly I think if I mixed on BX8's, when my mixes translated to other systems they would sound a bit enemic on the bass side as they were so hyped to my ears. Your ears may differ and that's why I stress to go listen for yourself. Good luck with your selection
