For 2 years, I use this model (curve 2) accompanied by 2 Subwoofers cb115 amplified in all but large Audiophony DBX filter anyway. Nothing to report yet. Remarkable strength, it sends the woods! Of course the fine is not that of a RCF system, or other large more expensive brand, but the product is reliable as long as it is not a nag who types in donf all the time and even then it still resists ... Audiophony has made real progress lately in almost all ranges of their products, it is time to reconsider the image some "PRO" funny want to give this French firm. We are no longer in the low end (see TSB Gemini etc ...) as some would have us believe snobbery and pure fluff! I recommend this solid product but we must treat her just the same, the quality robustness money is unparalleled. There are better without any doubt but the rates are in no comparable measure. This is only the opinion of a professional Disc Jockey since 1976. Musically!
