Any thoughts on this 108 cab?

[DaveCan]

A long while back there was someone who was telling Ron I think, that he had a way of loading the fe108ez and was getting down to 20hz.. I wonder if this is it? this?http://stereomojo.com/Gemme%20Audio%...kerReviewA.htm

What do you guys think?, pricey yes, but impressive maybe?

Nice looking cabs, a little like Sonus Faber. It would be interesting to hear them, good luck finding them in this town.

I wonder if the insides are just like a horn ,with compression chamber and horn path, and then the horn mouth exit is vented as a reflex system somehow, with the V-Flex technology they speak about? Dave

AFAIK, it's a mass loaded horn, pure & simple. The notion of a 108ESigma down to 20Hz though = a bad idea. Distortion, linearity, SPL issues... (need I continue?)

They don't appear to know much about turbocharging either, judging from their remarks.

Hello,

6moons:
Convincing as the Vivace's bass performance was in terms of extension (e.g. unheard of kettledrum from this type of speaker), it wasn't flawless. I don't mean that it suffered from the problems typical of a poorly integrated subwoofer - far from that. But there was an element that sent messages to the brain that the lowest bass notes seemed spliced to the remainder of the bass and emanated from the speaker as though on a second wave rather than as a continuous downward extension of the midrange. While the bass appears full range, it's not the kind of powerful bass of a bigger speaker descending slowly and smoothly into the basement.

smells like dynamic compression,
because the driver has an Xmax of 0,28 mm,
fullrange max. 0,3 W, nothing! even in a horn.

Very pretty piece and all that, but don't forget these are the same folks who astounded us with "the First Horn" a while back

who all remembers how that went?

[DaveCan]

Yes, I just thought it may be connected to the person that said they were working on a special way of loading or something.. I can't find it anywhere,but I think it was back when RonC was talking about working on a H108 enclosure, and this person posted there a few times with some interesting claims, can't remember it all or even find it..

Mass loaded horn?

>>> who all remembers how that went?

No, i don't remember? What happened?

I don't know which is less of a good idea... placing crossovers in critical ranges or loading a 4 inch driver to 20hz?
