Features

 

Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Prelude drivers, M.M.D. features a stiff aluminum core that provides exceptional strength and rigidity for clean, realistic low-frequency tones.

 

Amplifier: The 8" M.M.D. front-firing cone woofer is powered by a 100-watt (RMS) amplifier.

 

Surround: For a smoother response and improved durability, the woofer uses a rubber surround.

 

Bass Ports: There are two rear-firing bass ports that allow deep bass with high acoustic efficiency and low distortion.

 

Gain Control: The subwoofer has a rotary control on the rear panel for adjusting the level of the bass.

 

Phase Switch: The subwoofer's phase switch allows you to control the phase of the subwoofer's output relative to the front speakers. If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass "attack."

 

Auto On/Off Circuit: The auto on/off circuit turns the power amp on when a signal is sensed and turns the amplifier off and into standby mode approximately 10 minutes after a signal is no longer received. An LED indicator on the rear panel glows green when the amplifier is on and red when the amp is in standby.

 

Low-Pass Crossover: The subwoofer features a continuously variable 50Hz-150Hz low-pass crossover that determines the highest frequency at which the subwoofer reproduces sounds. The crossover has a 24dB/octave slope.

 

Inputs and Outputs Notes

 

Line-level Inputs: The subwoofer has a gold-plated LFE input and gold-plated stereo RCA inputs. If you have a Dolby Digital/DTS receiver or processor with a low-frequency-effects (LFE) output, you should use the LFE input on the subwoofer. If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output, you must use the stereo RCA inputs. If the receiver/processor has a mono subwoofer output, a "Y" adapter is recommended to maximize performance.

 

Speaker-level Inputs: The left and right gold-plated 5-way binding posts allow you to connect the subwoofer to a receiver/amplifier using speaker wire.

      Item Condition: Brand new unworn, full stickers.
      Reason for selling: Unwanted item.
      Payment Method: Pickup - Cash, COD Only or buyer organises own courier/shipping.
      Extra Info: I bought this brand new from Oversea Authorised Rolex Dealer with original receipt of $36k in September 2019. Model reference number is 118139, original warranty card, triple boxes & tags, this is a discontinued Rolex, so money can not buy brand new with full stickers. If you are into watch collection, you would know it is hard to get a gent Rolex nowadays & only few Lady Rolex in AD stores.
      There is not even one DD36 118139 for sale in Australia. Only few new DD36 for sale around the world & price at around $28.5-32.5k (with no stickers & date 2017/2018...)
      Also Rolex had increased price on 01.01.2020 from 10-12.5% depending on model. I am happy to meet at Watch maker or Rolex Service Centre to check out the watch.
      This would be a perfect gift for your beloved one.
      Donation of $500 if sold to member.
      Thank you.
