  • Anyone Familiar with GoldenEar SuperSub series?

    2x 8" Long Throw High Output subs
    2x 10" Infrasonic Passive Radiators
    All in a 1 cf enclosure that reaches down to 12Hz

    Could that be reproducible in DIY?

    Best Subwoofer - The new SuperSubâ„¢ Series subwoofers are ultra-high-performance yet amazingly compact subwoofers that incorporate many recently developed unique and advanced technologies and components. The goal was to create beautifully styled, finely finished, reasonably sized subwoofers.

    Sure, but maximum attainable SPL will be limited by using only 8" subwoofers. Enclosure volume is the grand leveller of all things.

      Don't see why not. Those rectangular passives may be hard to replicate, but a dual driver dual passive box with good drivers should be comparable.

      Note they provide no spec limits, charts, measurement data, or anything that could confirm that 12Hz spec, not even a "-3dB" note for it. That number could be entirely made up.

        None that I can see. I do see a number of claims that are simply wrong. For instance:
        Superior Transient Performance for Exceptional Detail; Performs Like a Well-Tuned Transmission Line but with Superior Transient Performance and Control; Resulting vibration cancelling yields accurate and precise low frequency performance; Room coupling is distributed much more smoothly.

          Any sub can reach 12hz if no level is specified - could be 12hz at -30db, but it still "reaches" 12hz. Using 8" subs would severely limit output and extension right off the bat for a given budget.

            Is there an advantage of rectangular PRs? They have about the same surface area of a 10" circular PR.
            Here is a review where they took measurements.

              Rectangular... the advantage is more Sd on the same size box, but no advantage acoustically.

              That review is helpful... the measurement graph in there is in room, and even then it rolls off mid 20's, so that 12Hz number is very, very optimistic. Perhaps in a sedan

              It looks like a good little sub.. but personally I'd DIY something similar instead for cheaper. A pair of RSS 8" subs with a pair of 10 or 12" RSS passives and a power to match should do it. Probably end up slightly larger, and not quite as OEM pretty.

                Looks like the UM8-22 is on sale for $99ea. The DSA315 12" is $36, the RSS315 is $90 for twice the Xmax.

                  From one of those linked reviews:

                  "A cursory single driver near field measurement showed roll off beginning around 25Hz, with more than enough usable performance approaching 20Hz."

                  It LOOKs like the FR plot ends right at 12Hz, about -40dB down from the output level at 25Hz.
                  There you go. (Also, the whole system definitely makes use of EQ in order to pour out the "magic" - like a river.)
