  What follows on page 28 in Exhibit C. is a page from Heather’s Acoustic Labs printed literature brochure printed in 2010 and relevant to Heather’s Acoustic Labs published Tower Crossover Schematic shown on page 25 in this Exhibit C. disclosing most all of the opposing patent’s claim 1 and further detailed in this Exhibit C.. The brochure was dispersed to those in the industry including to Dolby at the 2010 CEDIA Expo tradeshow and, with other technical drawings as Heather had presented her invention to DOLBY in hopes they would license it from her to license to speaker manufacturers like they did with their technology to receiver manufacturers.
  Refer to Heather’s published Acoustic Labs Tower Crossover Schematic shown on page 25 which is also further detailed relevant to the opposing patent’s claim 1 on page 24. The “Tower Crossover Schematic” on page 25 in this Exhibit which is illustrated as the back view of the speaker, IS a Crossover Schematic for Heather’s Acoustic Labs 5W-T Pedistool Towers on page 28 from her 2010 printed Acoustic Labs brochure that follows. Notably- the components disclosed at the top of the page of her Acoustic Labs “Tower Crossover Schematic on page 25 (also illustrated in the Tower Crossover Schematic as well), are the exact SAME as the components listed and illustrated for her Acoustic Labs 5W-T Pedistool Towers in the Acoustic Labs brochure page shown on page 28 which follows. Refer to the Specifications section from the Acoustic labs brochure page that follows on page 28.Under the the title 5W-T Pedistool Towers in which the tower speakers are shown directly below, refer to the Specifications section below the speakers. The “Components” are listed which are also illustrated in the picture of the speakers above. Notably the components are the exact SAME as the components listed and illustrated for her Acoustic Labs “”Tower Crossover Schematic” on page 25, Components- dual (two) 4” mid-bass woofers, dual (two) 2 ½” midranges (mid-high drivers) and, one soft dome tweeter. The Acoustic Labs “Tower Crossover Schematic” on page 25 in this Exhibit C. which is also further referenced on page 24 relevant to the opposing claim 1, IS a crossover schematic for Heather’s Acoustic Labs 5W-T Pedistool Towers on the page from her 2010 printed Acoustic Labs brochure that follows on page 28

   Referring to the page from Heather’s Acoustic Labs brochure that follows” on page 28 At the top left of the of the page under the “Connect As Conventional Speakers” section, underlined in green, disclosed is that the “Top mounted swivel drivers (2 ½”) drivers can be aimed upward” This language explicitly states the capability of the driver to direct sound in an upward direction.
 Shown below, in the “Activate Multi-Channel Processing” section which is relevant to the opposing claim 1,  the Acoustic Labs 5W-T Pedistool Towers which are illustrated at the left and right of the TV in the front of the listening area are Illustrated with red arrows dispersing sound upward from the top-mounted 2 ½” swivel “drivers”. The visual representation further demonstrates the upward firing of the top mounted swivel drivers aimed upward. The visual representation in the illustration graphically reinforces and confirms the upward directionality of the sound output. Further in the description under the “Activate Multi-Channel Processing” section which is underlined in green, further described is that that the audio signal for the height channel is positioned above under the illustration of the speaker with red arrows disclosing the top-mounted swivel driver is aimed upward for the height channel.  This detail explicitly links the upward-firing capability of
the swivel 2 ½” “driver” to the "height channel," which is positioned "above" in the audio signal.
  The prior art Tower Crossover Schematic on page 25 in this Exhibit C. which is further detailed in Exhibit C on page 24discloses a speaker system with a top 2 ½” speaker driver. However, the crossover schematic does not explicitly state that this driver is “up-firing" and "aimed/angled upward." The page from Heather’s Acoustic Labs brochure shown on page 28 clearly discloses the top 2 ½” swivel speaker “driver” is "up-firing" and "aimed/angled upward", “positioned above” for the height channel within the context of the speaker system. While the “Tower crossover Schematic” on page 25 doesn't explicitly disclose the upward angle, the combination of the Tower crossover Schematic on page 25 further detailed on page 24 relevant to opposing claim 1 and, the Acoustic Labs brochure on page 28 which teaches the benefits and implementation of an up-firing and angled speaker driver, would make the claimed combination obvious to a person of ordinary skill in the art at the time the opposing patent application was filed.
