48ms is already plenty to cause lipsync problems and will get even worse from upstearm room correction in an AVR or whatnot. If your AVR can output the front's coax/optical then you'd be good.
You‘d use the sub-out of the speaker itself and set the low/high pass frequencies in-app, so that’ll help a bit (rather than connecting the subwoofer upstream). But yeah, the higher the crossover the better but the speaker will still auto-compress the frequency response.I wonder how the bass management is (or isn't) designed to handle this.
If someone setup a sub around 96dB (brown line) and chose around 50hz, all would be good there.
View attachment 206218Then When they went to the black (normal) line listening level all would be fine there, since the speaker will low/high pass to send to the speaker/sub.
But what happens if they then go to the orange (very high) listening level? Will there be some (small?) hole from around 50hz to 80hz?
*not that anyone listens that high on average but I imagine dynamic peaks could go that high.

You would have to boycot anything that supports Tidal, i.e. pretty much any streamer worth it's salt..I‘m just not a big fan of boycotting every products that’s happens to have MQA support.
Full UnboxingDarko has a very short *unboxing* teaser on his channel that shows a fully exposed LS60 Wireless.
I made a similar simulation with @voodooless 's Tang Band W6-1139SIF. It's a small sized bass driver so it should perform more or less similar to the drivers KEF are using (if not a bit worse).
4 drivers wired in a 2 || 2 configuration (no impact on impedance) yield a sensitivity of about 93 dB/2.83V. If we take baffle step into consideration we're looking at a speaker that is more or less flat to 60Hz with 82dB/2.83V sensitivity. With a -6dB point at around 40Hz. With excursion for days. We're not even exceeding 5mm with 500W @ 4Ohm.

So a 16 dB drop already at 40 Hz which is even 20 Hz higher than the one of the LS60. Also baffle step has no real impact at the low frequency range but higher.4 drivers wired in a 2 || 2 configuration (no impact on impedance) yield a sensitivity of about 93 dB/2.83V.

It should be kept in mind that high excursion in a very small enclosure increases distortion significantly due to the highly non-linear spring characteristic of the inner air volume which can be seen also at the several countermeasures KEF takes against it like the SDCT.With excursion for days. We're not even exceeding 5mm with 500W @ 4Ohm.
I have a system in my bedroom with LS50 Metas and a KC62. The little sub is quite good - but only after I spent a long time finding the best place for it (ten feet away) and using EQ, I won't be buying the LS60s.I know it would be fairly simple and inexpensive to add room correction, but imagine if they had DIRAC on board. Just plug in a source or two and you’re set.
Hi Digitalfrost,Does anyone know high the Uni-Q is off the ground?
e: 1090 x 212 x 394 mm (42.9 x 8.3 x 15.5 in.) with plinth 1042 x 130 x 321 mm (41.0 x 5.1 x 12.6 in.) without plinth
These are a lot smaller than I tought. It seems the chassis sits fairly low then.
390 Hz. Plenty for the 4". 2 mm of excursion get's you to 112dB at that frequency. Given that in music content the signal is already way down from bass, so much will usually not be needed anyway.cant find info on xo. if its in the middle of the midbass then a puny 4" has to do to much.
I just did my own photo analysis before seeing this and got the same answer. Also virtually the same as the LS50 Meta on the matching S2 stand.The Uni-Q height is ~80cm. This is the same as R5.
