Wharfedale Pro Delta X12 - Passive 2-way acoustic enclosure with a 12" speaker and a 3" voice coil. The 1.4" compression driver with a 2" titanium voice coil is coupled to an elliptical horn with a 90°x 45° dispersion pattern. Compared to the Delta 12, the new X12 features an improved internal crossover and allows for bi-amp amplification. Thanks to multiple suspension points and a stand mount with 2 adjustable angles, the Delta X12 can be used equally well in installed sound systems as well as for mobile sound reinforcement.

Best quality, sound, price!

The best speakers in terms of sound presence, clarity of highs, compression, construction quality, and don't even get me started on the price...? Tested at maximum power with Zoom L12, Yamaha Q3031B, Mac 2.4 MK II classic high fidelity amplifier, top-notch sound... just like any passive speaker from Wharfedale Pro!!!***** I recommend! ?✌️
