Now they just need to build an 18” Speedwoofer that is a Dayton UM18-22 killer.
Shouldn’t be hard to do.
Then I will take them seriously.
Right now I merely respect them.
I don’t understand why the fascination with 18” drivers. A well designed 15” will perform just as well and cost less. The cabinet for an 18” is substantially larger than the corresponding 15”. The parameters that matter are excursion, power and lastly driver size. Port design is incredibly important.
A complete lack of understanding of specifications seems to also exist.
One user writes his speaker is good to 38db!
Clearly, that user meant 38hz but that’s a specification in a bottle. We need an output level with it. So 38hz +/-6db @ 93 db means that the speaker will be down no more than 6 db at any point in its frequency response. Without that data the frequency response is useless the output could be 84db SPl barely a whisper. Even the 93db number is wimpy. My subwoofer does 125db SPL at 34hz. It pounds! My mains hit 136db SPl down to 80hz. They mate perfectly with my subs. Additionally I time aligned the subs to the mains. Phase errors are so important to eliminate.
This is quite a diatribe. I hope it brings some understanding.
