Description

The BM9 is a versatile low noise ribbon microphone, with strong output, rich bass and clear, detailed top end. It is equally at home in front of a guitar amp or an orchestra. The BM9 brings you the best combination of vintage tone and modern utility.

Quality control is paramount with ribbon microphones, which is why every ribbon is made, fitted and tuned by Dr. Stewart Tavener, who has worked on thousands of vintage and new microphones. The BM9 is made in the UK*. All the metal parts are machined and plated in England, and the transformers are wound and the mics assembled  at our facility in York.

The BM9 is supplied with a solid wood box and hardtail mount.

Mechanical parts carry a lifetime warranty to the original owner. Ribbons are warrantied for 1 year from date of purchase, but with care should last many years.

    …a superb, hand built, ribbon microphone, in the finest tradition of Yorkshire craftsmanship and engineering. It produces an extraordinary level of fine detail. The low end is rich and full. It is a joy to work with…. I still can’t help going ‘Oooo shiny’ every time I open the lid of the box!

    “These are really great. Their tone sits between a 4038 and a Royer 122 and they have a lovely bass tip up. Slightly more pronounced we think than a 4038 at a given distance.”

    “I am really, really impressed with how good they are. I have a bunch of large ribbon 1950’s RCA 44 type mics and they stand up to them no problem and actually in a lot of ways are better. They have that large ribbon sound. Very natural, great highs and lows and everything in between.”

    I must spread the good word about these newly released ribbon mics — just got a matched pair of the Extinct Audio BM9s (nicknamed “The Viking”) -direct from the UK. They absolutely SLAY on piano – seemingly adding 2 feet (and a suboctave) to my Baldwin Grand. Huge but tight bass, with a clear and extended top end…not honky or nasal in the mids. Low noise (even through a 1073 with no Cloudlifter!), with lots of headroom. Can’t wait to try these on drums. These will deliver a big, warm, vintage-y sound on pretty much everything I throw at them. Oh, forgot to mention the cool retro design and gorgeous presentation in solid wood box with personal thank you note from Extinct Audio.

    The bottom end on these mics is rich and deep with a clear top end just like you promised. I really like it’s smaller size for a ribbon mic which makes it great for combining with other mics and getting close to source on acoustic instruments without crowding the performer. Great value for money.
