"With an Fs of 77Hz and a Qts of 0.3, the Fostex FE108E Sigma -- just like the other Fostex 4" widebanders -- begs to be hornloaded and so it has been, in myriad ways from fully exponential to spiral. While the Concerti 108 featured a more conventional folded horn (hybrid horn/TL), the novelty for Gemme's new models Vivace and Tanto is what the manufacturer calls VFlex Acoustic Loading.
What VFlex loading means exactly isn't disclosed. The manufacturer opens its coffer of secrets just this much: "This revolutionary acoustic loading technology operates by accurately controlling cone movements and accelerating air motion, much like a turbo charger in a car engine." Am I the only one to perceive deliberately cryptic descriptions here?
Regardless, the manufacturer insists there's some kind of a horn inside the Vivace. Paul Messenger measured Vivace's impedance response for his HIFI+ review and concluded that the speaker indeed seems to behave like a horn speaker so a horn speaker it shall be even though the rear port unmistakably suggests some sort of reflex loading.
...
For more than 4000 euros, the Gemme Audio Vivace isn't cheap. There are cheaper options available to enter the world of Fostex 4" wide-bandwidth drivers. Yet knowing what's gone into the Vivace's cabinet design and construction and taking into account its general level of performance, I think the price correlates quite nicely with the overall quality. And ten points to Gemme Audio for taking environmental matters into consideration during selection of building materials for this speakers (their website itemizes this detail)."
