You are buying a pair (2) of nearly new Neotera UF 295 CBS ultra shallow (only 2.6” deep, 3.2” including the top surround) aluminum cone subwoofers.  Nearly new mean’s the drivers have been tested with an analyzer and the frequency response, impedance and distortion measured, but never permanently mounted in a box or had music played through them, so basically just had incoming QC performed… better than new since the parameters and performance have been verified.  Some small marks from handling, but otherwise perfect.  These sell on the internet for $990 each ($1980/pair).  Shipped double boxed in original factory cartons.  Visit the Neotera site for more on this impressive shallow 10” aluminum cone subwoofers.  From Voice Coil magazine:

Features for the UF 295 CBS  are definitely impressive.  As you can observe in photo one, this woofer has a single piece (no dustcap) black anodized concave cone assemble that is suspended by two EPDM (ethylidene norbornene [ENB], dicyclopentadiene [DCPD], and vinyl norbornene [VNB]- 4-8% of these monomers are typically used) rubber surrounds, so does not use a spider for compliance.  The rear surround is attached to a large secondary black anodized aluminum assembly that is glued to the rear cone surface.  Since it creates a seal between the surround, cone and motor assembly, it has a series eighteen 6.5mm diameter air vents that provide both thermal convection cooling and equalizing venting as the airspace volume changes. Fig. 1 shows the details of the unique compliance system, which incidentally provides ± 34mm of mechanical excursion without damage.

  Both surrounds are 29mm wide and 20mm tall.  The cone is driven at its perimeter by a 283.4mm voice coil wound with aluminum wire with a black emissive coating on an aluminum former, also with a black emissive coating.  This is somewhat similar to the Prescient Audio TD-12 subwoofer reviewed in the August 2015 issue of Voice Coil in that the cone was also driven at its perimeter.  Since Prescient Audio is apparently no longer in business, this makes the UF 295 CBS’s and the UF 295 FAS’s 283.4mm diameter voice coil (300g coil mass) the largest diameter voice coil in the loudspeaker industry!  I should also note that this unique motor structure is covered by no less than 10 international patents.

  The motor structure is also very unique in that it uses a series of seventy two (72) 38mm high neodymium N35 bar magnets for a total magnet mass of 1.4 kg.  The 38mm high neo magnets directly drive the 12mm high voice coil for a 13mm underhung physical Xmax.  Interestingly, and undoubtedly the only solution, the entire 72 magnet motor is charged after assembly is completed using a massive 52 kilojoule magnetizer!  Incidentally, the drivers are produced on a semi-automatic production line in an Italian loudspeaker factory.  Remaining features include a 600W AES rated power handling, a frame made of Zamak 5 zinc alloy, and mechanical excursion of ± 34mm.  In a 24 liter (0.84 cubic foot) box, -3dB is 26Hz.  These are -3dB at 26Hz in a 24 liter (0.84 cubic feet)! 

 Please note, if you would like to see a comprehensive review of these drivers including SPL (on & off axis + polar plot), impedance, Klippel analysis, distortion and time domain measurements , message me with a request.
