    Brilliant little full-range driver. If you discount the various car audio coaxials I’ve used in the past, this is the first true full-range driver I’ve owned and I’m more than impressed with them. The first thing I enjoy is that I don’t lament the lack of a tweeter. I took the plunge thinking that it was going to be a sonic disaster, but I’m sold.

    The other surprise is how loud these can go in a real-world ‘listening with my ears’ testing/ownership. I running them above the rated power, however even at reasonable volumes, I’m more than satisfied.

    I do/did run a pair of Monitor Audio Bronze BX2 speakers, but I’ve not used them since i bought the CHN-70s’. Sure there’s a lack of bass weight/SPL from the CHN’s in comparison to the 6.5 mid-bass that the Monitor Audio’s, however, the bass from the CHN’s is better defined, and in every other respect the Monitor Audio’s fall far short.

    I have designed a tapered transmission line enclosure (yes a singular t-line enclosure housing both drivers) it’s a new design theory I’m testing out. I think a bit more fettling is needed. Any short comings is from my design, not the driver! I have to confess that I’m not up on crossover design, but that’s down to a touch of laziness to learn on my part, hence I gravitate towards coaxials and now full-range drivers.

    Of course I’m now eyeing up some other MA drivers, but make no mistake, I’m sold on both full-range drivers and Mark Audio.

    Can I just also add that for the most part I listen to a mix of electronic music, drum and bass, chill and on occasion I dip my toe in Dubstep. Old Skool dance from the likes of Prodigy (naturally!), Orbital, LFO and all that good stuff I used to enjoy in my clubbing days. Also and being a child of the 80’s, a mix of 80’s music, Duran Duran, Depeche mode, Culture Club, Adam and the Ants, some 90’s music INSX, ‘Now That’s What I Call Music’ kinda tunes.

    I do still listen to rap/hip hop, ‘clean’ version of the tracks, Public Enemy, Cypress Hill, N.W.A. and subsequent artist from that group, London Posse, Snoop Dogg etc.

    What I’m trying to say is that for some, I’m not the ideal candidate for such a driver. However, I maintain that the CHN’s have never faltered and handle my varied musical tastes in its stride. On occasion I do push these drivers hard, and not with what some might consider to be the ideal music … the ideal music that I see on many a YouTube Videos being female vocalists and classical music, live music and the like as the videos will attest.

    I love my music selection and the Mark’s allow me to enjoy them better … better than the Monitor Audio’s anyway!
