I acquired in 2005 two new systems deacon (or 4 heads and 8 sub) use I've never been disappointed. My specifications at the outset was comfortably able to sound with a tonnage of 100 to 1000 people and equipment it is always shot with honors. Compared with "brands" Institutional he did not blush at the comparison in terms of efficiency and effectiveness (for equivalent systems). The only reservation is made by sound engineers who hk audio is not a registered professional reference range. Certainly one can find better, a thinner medium, ergonomics most successful, but at what price ... for me the price / quality ratio is very good, the equipment is versatile (you can only use the heads in broadband, or the number of sub that you want to add sound depending on the point ...), the Integrated amplification provides a lot of convenience and reliability is at the rendezvous. I am parting with this sound for reasons that have nothing to do with any dissatisfaction with (I still also a complete system for sale) but I would do this choice without any problems.
