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.

      Hey guys, looking for options for a couple 24" sealed subwoofers. AFAIK there aren't any Australian places that make them, however I have found these places that do. I'm going to go with a passive subwoofer because the active versions seem to be prohibitively expensive vs passive plus an power amplifier (For example the Speaker Power SP2-12000 or SP2-6400). I'd also be interested in any suggestions for amplifiers in Australia that are as good or better than these amps for the same or lower price than these.
       
      24" subwoofer options - 
       
      Stereo Integrity HS-24 Driver only. - $1,399.99 USD (Plus $800 - $1000 to get a cabinet built locally here in SA) Also haven't responded to my email for shipping. Funk Audio - 24.0E - $4,670 USD (Plus shipping etc. Fully built ready to go just an input needed). Only 2200w though and could definitely be pushed to 4000w+, so losing some output there. Funk Audio 24.0 - USD 8,900.00, but can get without an amp or with external amp, currently waiting on email back for pricing without their amp. ( I wouldn't buy this for $8,900 USD, maybe half with an amp, but 8.9k USD is way to rich for a single sub with these other options available!) Harbottle M24 (Passive) - $4,100 AUD for efficiency tune, $3,900 AUD no efficiency tune. Best option? (From their page - "The efficiency tune results in a little more top end extension and higher efficiency in the low end. Overall a cleaner and better dymanics per watt. ") MARIANA 24SR - $4,000 USD. Looked like the best option at 4,400w amp all ready to go, however they don't ship internationally so that's VERY unfortunate for me!
       
      Amplifiers - 
      I only know of this amp that's good quality that will last and suit subwoofers. Unfortunately the SP2-8000 is only 120v, I'd get it otherwise.
      SP2-12000 - USD $3,799.00 (Plus USD $450!!!! for shipping) (8000w peak)
       
      SP2-6400 - Unsure. But lower power at 2ohm. (Rigo repsonded via email.)
       
      SP2-6400-HT
      - 3200W @ 4 Ohms
      Per channel both driven
      - 113V RMS @ 4 ohms
      *Requires 230V mains to achieve full power (half power at 120V)
      125 V
      Amplifier
      Wattage / Voltage RMS
      MAX OUTPUT VOLTAGE
      SP2-12000-HT
      - 6000W @ 2 Ohms
      Per channel both driven
      - 113V RMS @ 4 ohms
      - 110V RMS @ 2ohms
       
      *Requires 230V mains to achieve full power (half power at 120V)
      125 V
       
      Does anyone know of any other options?
