The AKG C391B is actually the SE300B plus the CK91 cardioid capsule and is great for all small diaphragm condenser mic applications. The AKG C391B combo is one of the best all purpose, small diaphragm condenser mics ever made for the studio. And you won't find a new-in-box complete package like this anywhere these days. Only tested after purchase years ago and again before listing it here.
You are looking at a MATCHED SET—TWO C391B mics (with two CK91 cardioid capsules) as well as TWO CK93 hypercardioid capsules to swap in and out of the SE300B mics as your recording needs dictate.
These were held in the collection of a celebrity recording artist after acquiring them from a famous record producer/engineer. The artist kept them as a backup and they're part of a set reserved for drums or small ensemble instrument mic-ing. Untouched—they sound pristine and transparent. A true find these days. Come with cases, manuals, test specs, windscreens, mic clips as well as individual capsule cases.
IF you wanted to get the entire set (if still available) then let us know and we'll put a package price together for you. In addition to two rare matched C391B combos and two CK93 capsules, the set would also include one rare C460B (mic+capsule) and the even more rare original Audix D1—four mics in total.
Being offered by the celeb artist along with a ton of other really high end pieces to raise money for the artist's charities. Names will not be given out—only to the buyer. Selling this on the merit and quality of the rare (whole) microphone package as well as the outstanding pristine condition that is unheard of for mics like this.
Guaranteed to be clean and COVID free. No meetings without masks and distance.
Please no time-wasters or harassment. We're trying to do a good thing here to raise money to help people—serious inquiries only.
Thanks for stopping by. Stay healthy.
From AKG: The C391 B high-performance small-diaphragm condenser microphone is a combination of the Blue Line Series CK91 and the SE300 pre-amplifier. The microphone has a cardioid polar pattern, a low self-noise and very good transient response for a bright and brilliant sound. It also features the ability to quickly interchange its capsule with one of the other capsules of the Blue Line Series, making it an excellent mic for demanding broadcast applications. The C391 B provides a switchable bass roll-off/attenuator with three positions: flat, 75Hz and 10db attenuation.
The CK93 high-performance small condenser capsule is characterized by a smooth and well-balanced frequency response and a consistent hypercardioid polar pattern. It provides greater attenuation of off-axis sound and more direct sound. Thus it is the ideal choice for critical live and studio broadcast applications where consistent suppression of off-axis sound is required. The CK93 is part of the Blue Line Series and works exclusively with the SE300 B pre-amp module. Its robust Modulock bayonet coupling allows quick and easy changing of the capsules modules.
