i have a pair of these ribbon speakers. One of them has a puncture in the ribbon. See photos. Both speakers work, sound good, and ohm out at 5.7 ohms. One of them has a mounting frame while the other is the speaker only. Local pickup only due to their size.

Listing is for 1 pair . Brand new high end in wall speakers. These are fantastic sounding! Selling as parts or repair due to the nature of this website. Returns not accepted. The drivers and crossover in this in wall setup are outstanding and could be used to make a wonderful 8-in two-way speaker. Top notch component. A pair of 8-in woofers of this quality would cost you more than what Im selling these for . I have 2 pair brand new in box. They are listed as parts or repair due to the nature of this website. Below are some specs. Thank you for looking and have a great day! The largest In-Wall / In-Ceiling model in the PD Series of custom loudspeakers, the PD-8i is capable of filling large spaces with richly detailed, natural sound. With the proprietary Neo3PDR planar ribbon tweeter, it also minimizes any floor or ceiling reflections, improving the sound clarity and accuracy for an impressive home theater or two-channel experience. To add to the tweeters excellent dispersion and resolution, the PD-8i features an innovative woofer with high excursion capabilities and very low distortion. This high tech woofer design makes use of compact (but powerful) Neodymium magnets to provide an acoustically transparent woofer chassis which dramatically improves midrange clarity by eliminating sound reflections directly behind the woofer. The superior Kevlar cone woofers used in the PD Series not only provide superior two-channel clarity but are also capable of achieving the extreme dynamics associated with high performance home theater applications. As with the entire PD Series, the PD-8i is crafted from high impact, poly-composite frames that are well suited for the entire home. Rugged, paintable surfaces are the perfect architectural complement for custom installations. Crisp and clear.versatile.The PD-8i makes design and install of a high performance In-Wall or In-Ceiling sound system not only possible but remarkably simple. Exclusive wide dispersion patented wideband PDR planar ribbontweeter for an extremely wide sweet spot over the entire listening environment. Powerful Kevlar cone woofer feature a rubber surround, Neodymium magnet and acoustically transparent chassis for high output with minimal distortion. Easy to install, Improved poly-composite frames (paintable), rust-resistant metal grills and glass-filled composite toggle clamps simplify installation.

I have four (4) sealed new great B&G BG Bohlender Graebener Neo8PDR Tweeters for sale. I am going to sell them ONE (1) piece at a time. I will offer discounts for multiple units if more than the one piece this ad is for. If that shoud happen to be the case message me and we can work that out before hand of course. It will go out wrapped very snuggly in bubble wrap to you.

The RD75 speaker is designed for applications where a flat, resistive impedance and wide frequency response are desired.The aluminum ribbon conductor combined with a tensioned polyester film diaphragm suggests that this is a type of ribbon or planar magnetic driver, known for their detailed and clear sound reproduction.In practical terms, when designing or incorporating this driver into a system, it would be important to use an appropriate crossover network (at least 12 dB/octave at 150 Hz or higher) to ensure longevity and avoid pushing frequencies to the speaker that it isnt designed to handle.The sensitivity of 88 dB means that for every watt of power provided to the speaker, it will produce a sound pressure level of 88 dB when measured from 2 meters away.Bohlender Graebener (BG) was a company located in Carson City, Nevada, that produced high-quality planar magnetic audio transducers from 70s to about 201x.They have been available for DIY or sold directly to manufacturers and many ultra hi-end speaker brands choose those drivers such as Genesis due to their design. This version is RD-75 and those are top of the line models, speakers are huge,looking at the RD-75, you realize that 144 in2 is not too shabby for a mid/high frequency driver. Because of this large area, the RD-75 diaphragm moves a relatively short distance even at high volume levels, resulting in lower IM distortion.And the most endearing feature of these drivers is that they cover the mid/high frequency range in one driver, including the all-important human voice range.Those drivers can present a huge soundstage and extremely transparent mid/highs to almost any music reproduced. I have used those speakers in dipole variation for quite a long time and with a progression of DSP and room correction systems lately I decided to keep only one pair to satisfy my needs.Units have been connected to amplifier over digital crossover while always having a passive High-pass filter (HPF) filter protecting their membranes. While you can find a pair or 2 on the used market they become very rare. This pair is in excellent condition and well maintained. I hope it can find a new home and owner.Model: RD75Effective Frequency Range, Sealed Enclosure (-6dB from average SPL): 125 Hz – 20 kHzFrequency Response, Sealed Enclosure, 1m, with Notch Filter: 150 Hz – 18,500 Hz ± 3dBImpedance: 6 ohms, resistiveSensitivity (Equivalent to 1W/1m, Measured at 2m): 88 dBDiaphragm: Tensioned Polyester film with laminated aluminum ribbon conductorsMagnet System (All drivers are magnetically shielded): Symmetric, push-pull, with Ceramic 8 magnets enclosed in a steel chassisPower Handling:RMS: 100 WProgram: 200 WPeak: 400 WCrossover Network Recommendations: 150 Hz, minimum 12 dB/oct. electrical minimumDimensions (H x W x D): 75.563 x 4.675 x 1.53Weight: 35.5 lbs.Diaphragms:PolyesterPolyethylene napthaliate (PEN)Polyamide (Kapton)Conductors:Deposited aluminumEtched aluminumEtched copperVarious surface applied wound metal wiresFrames:Carbon steelStainless steelVarious molded plasticsMagnetic Materials:Strontium-ferrite ceramicIsotropic and non-isotropic alnicoSamarium-cobaltNeodymium-ferrite-boronDue to size/wight it is a pickup/deliver option only for Richmond VA, Northern VA, DC Metro area
