The bass extension is so deep that the LFX is <20Hz, only other speaker I have done that also did that was the D&D 8C.
Here's the Spinorama in my typical format (note graph only goes down to 30Hz as usual, for formatting):

KEF is really on a run in the last years, every series comes with some impressive engineering which is nicely documented for us "geeks" in their white papers.Looking at their site page, i've read the whitepaper and a thought lingers in my mind - My God they're great.
See where I mentioned the LFX score, the bass extends so deep that the formula needs to look below 20Hz and it breaks down.Thank you for that, out of curiosity, what is the score without sub?
I must take back my words, saying they are stuck in limbo between great products for the money and slightly better but enormously more expensive. This one if it matches their white paper can be first KEF speaker for 6k that actually has got a good maybe even great valueLooking at their site page, i've read the whitepaper and a thought lingers in my mind - My God they're great.

For the exact same model I see the chances very low mainly due to the special EQ and limiters for using those 4 woofers in that small not ported enclosure.ok, i never was enough into Kef to know all their models, but....how's the outlook for a passive version of those?
I see, I’m not well-versed in how the score is calculated, hence the ignorance of my question. Thank you anyway.See where I mentioned the LFX score, the bass extends so deep that the formula needs to look below 20Hz and it breaks down.
I'm not following why a 'small' non-ported enclosure is an issue. for me it's rather the opposite.For the exact same model I see them very low mainly due to the special EQ and limiters for using those 4 woofers in that small not ported enclosure.
Because loudspeakers in too small enclosures need heavy equalizing to get low linearly and which also limits their max SPL so also intelligent limiters are recommendable.I'm not following why a 'small' non-ported enclosure is an issue. for me it's rather the opposite.
That's fine and all but that's not really a reason that makes the design impossible.Because loudspeakers in too small enclosures need heavy equalizing to get low linearly and which also limits their max SPL so also intelligent limiters are recommendable.
This gives a good idea of their actual size - interesting that concentric is mounted so low, looks like it would be well below ear level even seated. With how small they are I wonder if people will end up using them not as floor standers, but sitting on the TV console instead.Unboxing
Makes selling it as passive 'impossible'That's fine and all but that's not really a reason that makes the design impossible.
Almost anything is possible but that does not make it automatically expedient, in passive loudspeakers you cannot really make a positive sign EQ* so you would need to shelve heavily down all the rest of the spectrum (probably to less then 75 dB/W/M), also not really expedient to implement an intelligent/adaptive limiter on purely passive high power domain without its own power supply.That's fine and all but that's not really a reason that makes the design impossible.
No mention of latency.
