Product Details

Bohlender Graebener Neo8 Planar Transducer

The Neo8 features a push-pull magnet system that has been designed with the help of Finite Element Analysis software to achieve optimum efficiency/cost performance. There are no heavy voice coils, spiders, glue joints, paper cones and surrounds. Hence there is no cone break-up resonance, distortion, phase incoherence or signal smearing that is common in conventional drivers. With the Neo8 there is virtually nothing between the electrical signal and the sound- just an almost weightless diaphragm. No other commercially available loudspeaker transducer is so pure and so "minimalistic." No wonder the Neo8 delivers clean, airy, transparent sound that is inherently natural and musically pleasing. The purely resistive impedance of the Neo8 makes an easy load for a power amplifier and greatly facilitates crossover design. The magnet system is completely shielded for safe implementation in multimedia and A/V systems. The Neo8 is a very versatile driver and its applications are limited only by the designer's imagination.

Bohlender Graebener Neo8 Planar Transducer is rated 4.7222 out of 5 by 18.
Rated 5 out of 5 by from Listen to the rest, buy the best!I live in Reno Nevada, have traveled to the B&G plant in Carson City…years ago. Been building my own speaker systems for 40+ years and listening to store bought High end systems around the world. Haven't heard any tweeters any better than the B&Gs…also, have bought 3 pairs of them, 1 for my system, 1 for my son's and a backup!

Rated 5 out of 5 by from Dont judge a book by its coverThey don't look like much but they sure do sound like a million bucks! I just wish a mounting plate was available from the Manufacture for those of us that want to mount these in a cabinet. I have these mated to the B&G tweeter and 2 HiVi 8inch woofers and they just sound awesome. The way they fill the room with sound is incredible!

Rated 4 out of 5 by from everything you need and wantI used these in a pair of TMM main towers using 8" hi-vi woofers. towers are ported @ 40hz and crossover is at 1800Hz using 6db/octave. The towers are 4' tall and places the planar at ear level. they are an absolute delight to listen to for music and movies.the only bad i can say is the connections. i had one fall completely off and had to solder speaker wire directly to the film to get a connection.

Rated 5 out of 5 by from Replaced midrange in Martin Logan MosaicThe mid range and tweeter drivers in the Martin Logan Mosaics are Bohlender-Graebener Neo8s and Neo3-PDRw drivers. Parts Express offers these drivers at a price substantially lower than that offered by Martin Logan.The only hitch in installation was that the diaphragm is sandwiched between the front and back metal covers and covers the mounting holes. These holes are easily punched through with no ill effect.This driver sounds fantastic with very low distotion, wide dispersion and great power handling. I'm blaming the failure of the original on a very rough move. The Mosaics are fragile speakers with the mids and tweets mounted in a very flimsy plastic frame.

Rated 5 out of 5 by from Amazing!Very good wideband driver, in my opinion one of the best if used as a linesource!

Rated 5 out of 5 by from TRANSIENT TOWN USAIf you want to have some fun get a pair of these things. The ability to project multiple frequency signals is exciting.Put on some old analog recordings and hear signals you didn't hear before... My application is crossed over @4000 but I have used it 1000HZ too. Don't be scared to solder the terminals, use a gun type solder tool. In and out!!!

Is there a back wave that comes from the rear of the Neo 8 and 10? Dipole?

Asked by: thairon
Yes these two models are open back and can be used for a dipole application.

mounting plate ?

where can i purchase a mounting plate for the neo8?
Asked by: Dr Noob
Not quite sure what you mean by mounting plate. The Neo 8 is designed to be either used open air back or in a sealed space. If open air - you would have a baffle with an opening and afix the driver to the face with thin speaker gasket under the edges. Then the sound would radiate front, and rear reflection offf the back wall - often referred to as bipolor or dipolar. In a sealed situation - you want at least 100 cubic inches of volume lightly stuffed. While the Neo 3 does have an optional mounting plate - there is no such plate available for the Neo 8

Use in a 2-way surround

I am considering using the neo10 in a 7.2 surround system. Im considering a mutitude of woofers and leaning towards something with fast transients. Maybe 2 - 6".. I want to keep the efficiency high while retaining dynamic responce. i will most likely high pass the entire speaker at around 80-90 - ish and xover the woof and transducer at 900-1000 at an 18 db slope.I would like some recomendations on my design thought and some suggestions for woofers.......
Asked by: bbeard
The NEO10 is a state-of-the-art driver. You will be impressed with the performance in a well integrated system. BG supplies drivers to companies retailing speakers of over $25,000 using variants on this design. While the driver has extended response to 20K, it beams and has impedance issues in the upper range. It's sweet spot is up to about 5000hz. Crossover from the NEO10 to a NEO 3PDR 6db/oct. If you use the NEO 10 down to 500, go with a 24db/oct crossover - more linear than an 18. If you cross at 800+, you can skate with a simpler 6db/oct and still have a lot of headroom. Without spending a fortune on woofers which is easy to do, yet getting a driver without compromise - check out the Morel MW164. It's a work horse and blends stunningly with the NEO series. I currently am running MW164 with NEO8 and NEO3PDR with 6db/oct at 500/5000. The mids and highs are open air and the woofs are in sealed enclosures with a Qts of .707. Have fun with your project

Use as a mid/tweeter?

I'd like to cross this at 800 Hz and use it as a midrange/tweeter in a 2-way. How well does it handle high frequencies, though? Assuming I used the recommended notch filter at 12k Hz, would it match a dedicated tweeter, or should I plan on a 3-way system?
Asked by: WSmith
I would suggest giving it a shot on its own, at least initially. I cannot dictate what will (or will not) sound "good" to you, specifically, but you can always add a tweeter later if you determine that the upper-octave performance of this product isn't sufficient.

Are the terminals compatible with push-on disconnects? I would like to avoid soldering on these drivers.

Example: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=095-287
Asked by: StCredZero
Yes, the terminals are male quick disconnects. However, rather than the 3/16" size you mentioned, you'll want the 0.205", which I've referenced below for your convenience. The 3/16" connectors will be too small.
