Thanks for the info.

What is a fast sub, I mean... what spec (and value) defines that?

Specs are tricky. Audition! You hear

Is "fast" one of them subjective measurements?

It may well be, personally I got various speakers, amplifiers and completed subs through friends at Klipsch and did my own experimenting. There was a Martin Logan in the batch as well as another brand whose name I forget. I believe I started with seven or eight and gave some parts away to a friend who did cabinet work for me. I can recall liking the smaller speaker setups for two channel audio so I figured those might be considered fast.

Don't look at anything ported or slotted. Stick with sealed enclosure subs.

I also prefer sealed

I'm also using a silver Yggy with a black Raggy, no effect on the sound IMO

Oh but that's odd.
I have Piega speakers. Swiss aluminium top quality.
They are delivered with black and alu fronts.
And I am sure the sound difference is remarkable.

With subs, there are some things you feel but do not hear. Below 20 hertz is infrasound, some special effects in movies go pretty low (seven hertz or so) but that is of less use for two channel audio. 18 hertz is the resonant frequency of the human eye but many special effects are not a sustained sound. Getting down to 7 hertz and sustaining it you get really close to the fundamental frequency of the human body.

Two words: Pipe organ.

while normally yes sealed is better for being fast and transient i can say if designed correctly and taking into account the actual drivers specifications a ported PROPERLY tuned enclosure can sound just as good and 99% as fast as a sealed box while being more efficient. ive done enclosure and box design for over 25 years. the biggest thing with ported i see way to often is they are just not either designed properly or tuned properly or both even from large manufactures.

Very good info. By no means do I have your experience. It is like any area in electronics, work with pre-amps a lot like @TomSix or Wayne Colburn or Dacs and amps like Mike or Jason and you become very good in that area. I might have spent a couple months working with sub-woofers myself and grabbed a small selection so I could pick what I liked best.

True. Has a lot to do with the size of the cabinet. I believe ATC goes ported above 20 liters in order to control the pressures

Oh man... when is this announcement coming? It's killing me over here.

For those of you pushing Vidar into the +100 db range. Have you noticed (subjectively) any distortion or other graininess at higher volume levels? How does the Vidar work at low volume levels? When I upgrade my 2 ch a fair bit of my listening will be done at night, in low light, at low to very low listening levels. Wondering if you can still hear all of the details at low volume.

Vidar seems fine to me at modest levels. I have discovered that the light - low or otherwise - makes no detectable difference

Yeah, I'm in the same camp, specs are nice when it comes to narrow the candidates for a new purchase, but at the end of the day, the ears are the "ultimate test".

I was asking cause I assumed you were talking about a measurable parameter, but it seems "fast" is just your own subjective subwoofer rating.

Thanks for your input, anyways.

That would be the 688, Los Angeles class or its updated version, the 774 Virginia Class. At least in the USA.
