Product Details

Bohlender Graebener Neo10 Planar Transducer

BG's newest patent pending planar-magnetic transducer, the Neo10, offers excellent sound quality and is suitable for a number of applications as a high-performance wideband midrange. The Neo10's low mass, high temperature diaphragm is directly driven for high power handling, outstanding transient response, and superior damping. A carefully engineered push-pull symmetrical motor structure produces a focused magnetic field for inherently low distortion and high sensitivity. Very low self-inductance minimizes intermodulation and phase distortion for increased accuracy and coherency. The resistive impedance of the Neo10 motor circuit presents a non-reactive load that is amplifier friendly.

Background

The Neo10 is the next step in the line of BG's planar ribbon drivers. The design goals include higher sensitivity, lower distortion, a lower usable cut off frequency, and higher power handling than previous offerings. This provides a solution to an important system goal – uncompromised reproduction of the human vocal range.

An additional benefit of the extended bandwidth is improved integration with a dynamic woofer. Seamless integration has been a challenge in practice historically and this is much easier to accomplish at 150-250 Hz than at an octave higher.

Construction Details

While the Neo10 has design principles similar to the Neo8, its construction has significant differences. The goal of extended low frequency reproduction dictated the use of a larger magnetic gap for higher excursion. Large magnets were used to further increase magnetic flux density in the gap. The magnet system is a symmetrical “push-pull” configuration that has proven to offer low distortion and improved sensitivity. The Neo10 also uses significantly thicker metal for its plates to provide the required dimensional stability when using a physically larger magnet structure. Plate shape also becomes analogous to diaphragm shape under excursion, which facilitates extended low frequency output. Specifically tuned fabric screens have certain acoustical resistance and play an important role in stabilizing and damping of the Neo10’s diaphragm. Finally, the NEO10’s unique diaphragm technology provides low distortion and the ability to reproduce signals down to 150Hz, thus achieving the driver’s design goals.

Bohlender Graebener Neo10 Planar Transducer
Bohlender Graebener Neo10 Planar Transducer is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from Unbelievable!My beloved Monsoon MM700 desktop planar speakers were dying a slow death. These seemed like the ideal replacement for a DIY desktop PC speaker, albeit way more expensive. I settled on the NEO 10 and Dayton Mini -8 AMT tweeter, with a simple first order crossover around 3k. I didnt worry about a fancy x-over as the desktop has a manageable listening position and beaming wouldn't be a huge issue. The speakers are dipolar in a simple open baffle with tweeter above, resembling a mini pair of magnepans for the desktop. In free-air, the NEO 10 needs a bit of EQ boost in the 250hz range for near-field applications. They handle the power and EQ well. One of my concerns was over-driving the speaker in this 150-250hz range, but they handle it really well. The EQ is done with a MiniDSP and an 18db/oct 2 way xover at 150hz and a Dayton SUB 80 handling the bass. A NAD 3020 drives the speakers. 30 watts is way overkill for the desktop, as efficient as they are. You could get by with 10-15 good watts as a desktop system.The sound is nothing short of amazing. 96k FLAC files lead to some of the best audio I've heard, period. The sound is super detailed, clean, and dynamic at the same time. They sound like good electrostatic or planars, but with better cone speaker-like attack on the dynamics. You can follow individual instruments or voices in complex arrangements because of all the midrange detail. With the MiniDSP, it was easy to get to + or -2db from around 40hz to 16khz. They sound like Magnepans, but with better dynamics, and more detail. In short, they are amazing and will have you listening to all of your recordings again.It was a bit of a stretch to think that a sub could play really cleanly to 150hz and match the NEO 10, but with some EQ in that range, it worked out well, perhaps because of the flexibility of the MiniDSP 2x4. I'm not sure this would play in a large room with the same results, so bear in mind all of this is in a near-field setup on a desktop, where output levels can be lower. In a large room, you might need to cross over higher and have some sort of mid-bass driver in addition to a dedicated sub.

Rated 4 out of 5 by from SpookyUsed this in a Helmholtz calculated "un-cabinet ". 2 12"x19" panels with a neo 3 tweeter above the front mounted neo 10. It's chamber is in a 6.5" deep enclosure tuned to 400 hz via a 4" round port, directly behind the driver, acting as a transmission loading dipole radiator. Tube amps are line level filtered with in line caps, speakers biamped.In tandem with a 500 watt Yung plate amp driving 10" Dayton reference subwoofers, these throw a fantastic sound field . Seemingly everything makes from the source to your ears. Direct coupling to filtered amps takes these from stunning to amazing.

Rated 5 out of 5 by from BG Neo 10Once you hear them, you can truly understand all the good things said about these drivers. We've all read the hyperbole about planars in general and the BG Neo10 in particular, so I had to give them a try. My plan is to use them in a WMTMW open baffle design, but I just had to hear them right when they arrived. Hooked one per side up with just a cap and and a 15" wide range OB, no crossover and no tweeter. Of course, nothing even resembling the final build. Started listening to some familiar music---------just started to giggle like a school girl! These are so good they give you goose bumps. If you have or haven't given them consideration, wait no longer-----JUST BUY THEM. YOU WILL BE EXTREMELY HAPPY!!! -still giggling.

Rated 5 out of 5 by from One of the best mids you can buy, BUT...Tougher natural frequency than most cone drivers, but use it well and it's hard to beat. It won out over many high quality choices for me. A natural for dipole projects, but works well as a true mid range in monkey coffins too. Just remember to seal it off from the woofer. And DO NOT solder on this driver, use crimp terminals or you might fry the diaphragm if you are not a great solderer. If you use a Radio Shack iron, forget it...

Bohlender Graebener Neo10 Planar Transducer

Is it reasonable to drive these to 150Hz using a 48db/octave active crossover on an open baffle?  The manual says to stay above 250 but that assumes 2nd order filter.

Asked by: jt128
This really depends on the amount of output you want from the driver. It would be best to take actual measurements in the intended application for frequency response and distortion, at different output levels in order to see if this would be a safe frequency with that driver. It will probably be fine for low to medium output levels, but higher levels require multiple drivers.

I'm running very loud professional mid-bass drivers with efficiencies from 96 db to 99 db. Will this work? Is it possible to use tweeters with lower efficiency with higher efficiency speakers?

Can it be directly connected to amplifier without capacitor?

Asked by: Jay lee
You will want to have a high pass filter on this driver before you connect it to an amplifier. I would recommend no lower than 150 Hz second order.

Recommended tweeters? this looks like a really attractive candidate for a 3 way active setup i am contemplating. what are tweeters that'll "keep the show going" in the upper octaves.

Asked by: Kapil
The best tweeter recommendation I can make for this driver is a Neo3 or Neo3PDR.
