Up for sale: I have fourteen pairs of brand-new-in-box Mark Audio (Markaudio) CHP-70 Gen.2 wideband drive units with the charcoal black paper cone. I mentioned these in my charcoal / black colour cone CHP sale thread here: FS Mark Audio (Markaudio) CHP-70 Gen.2 drive units (charcoal black cone) They are the same unit, the only difference being the black / charcoal colour cone.
For background interest the CHP-70 Gen.2 was developed by Markaudio in conjunction with their Japanese distributor and a number of his jazz / small club playing and listening enthusiasts. Their object was to create a 4in wideband driver with a semi 'vintage tone' that captured some of the characteristics of classic wideband units, with a lightly shelved down top end and smooth / natural midrange tone. Between the original unit and the gen.2 MA changed its graphing scales &c.: the drivers actually have similar responses, but the Gen.2 models introduced a raft of upgrades: an improved basket, a new central cap, Japanese designed low-mass coil and a new spider design providing a 12% reduction in moving mass.
Main CHP-70 Gen. 2 features:
-Usual Markaudio shallow-profile cone for consistent off-axis response
-Reinforced self-damping polymer basket
-Long-throw suspension
-Well balanced Fs, Qt, Vas to suit different types of load (works well in sealed, vented, horn & QW -two examples below in resistive vent marKen standmounts, and used as wideband midbass drivers in a pair of compact floorstanders)
-Black (charcoal colour) paper cone
-Supplied with factory gaskets and connecting hardware
I'm asking £30 per pair plus shipping (less than half normal retail)
All drivers are packaged in their original Markaudio boxes. I use sustainable FSC rated outer cardboard boxes fastened with heavy-duty packing tape. These are reinforced inside with recycled heavy-duty cardboard and packed with recycled brown / grey packing paper and high quality bubble-insulation.
Thanks as always for looking, and if you have any questions, please don't hesitate to ask.
