KEF LS60 Wireless - Finally! a buzzword compliant wireless speaker that I would buy

My guess is that it would depend on where you put your crossover point. Most people are able to localize sound anywhere upwards of 100hz, so as long as the woofers are operating below that it would probably be fine. Anything above it would sound a little strange since the lower portion of the bass will come from one side of the speaker asymmetrically. Does anyone know if there are some off-the-shelf drivers that can be modified to a similar end to reduce the space they would take up when placed back to back?

When drivers are placed back to back (so called “bipole” config) on a slender prismatic box, and they operate in phase (push push), below 200Hz or so, they act like an omnidirectional driver. You could have a driver on each of 4 sides and it would be similar. This can be seen on simulation of the polar response. One advantage besides omni directionality at lower frequencies is the reduction of baffle step loss.

So for lower frequencies, even though drivers are side mounted, if crossover frequency is properly set, they will sound as if they are on the front. Having two drivers one above and below improves vertical polars line an MTM.

Jack- great engineer and communicator/marketer.

bit of BS and first world problems regarding that part regarding packaging and Darko’s ability to unpack it. OMG. 🤪

so who’s got one order for free in-home demo?!

It all depends of the electronics imho.
If this is 'disposable' boards (as in many products, 'don't bother repair it'll cost the same to change the board') then yes i agree with you Tmuikku. Smps are often the weak link ime with powered nearfield ( studio nearfield).
If it is done to be fixed then it's a mater of 'obsolete' formats: how long will the one availlable at purchase stand?
As long as there is good adc and dacs it doesn't really mater in my view ( but yours can be different).
 
Given good longevity of transducers and cabinets and quite *short longevity of electronics, i think that future is in passive loudspeakers with smart dsp powered amplifiers (Bluesound Powernode N330 might be a good example) or DSP active loudspeakers with interchangeable exterior electronics (one example would be JBL M2).

As i understand, problem with latter is that there is no particular standard about DSP's - people design a crossover by MiniDSP and when you try to apply those transfer functions in Hypex Fusion, you somehow end up with different results (or i understood incorrectly?).

*there are so few brands that offer long term serviceability. I don't enjoy being forced to a certain brand for that reason only. If i have to pay big bucks for something, i need to like the tech, sound, looks, i want 10y longevity and at least 15y serviceability. It's a lot and no brand known to me fulfils all of those five parameters. So passive it is for me.

The biggest issue with the transfer of settings from one hardware DSP to another is that the definition for Q in a Parametric Filter and also what constitutes a shelving filter of what type changes. There are generic types but each designer seems to like to go their own way. So you have understood correctly.

Yes it is true, different results from different gear ( supposed to be the same). But this is not as an issue as one can think: it's all a mater to be able to compare results between gear and compensate for it as luckily it is somewhat 'linear' difference ( once you found 0.705 on unit A is equal to 0.702 on unit B it 'll give consistent results).

To be honest it can be an issue for P.A. engineer using systems with different processors on daily basis, or if you have to migrate from one dsp to another but in each case it is a mater to have a template of acoustical target and ( often very slightly) tweak between processors.

And it is often forgoten the same apply with analog eq: between constant Q ( Neve Vserie, SSL9000, 4000G), constant gain ( SSL4000E, Vintage Neve), etc,etc,... the same template will sounds differents. It's true for the 31band eq too as all cells are not implemented the same way...

In fine it's a no issue as long as you have a record ( for a migration between processor or clearly defined goal if from scratch) of final acoustic target.


That is the reson i choosen to have a modular/open system vs an integrated one ( like plate amp including dsp and multiple amps). The price to pay is in cost and bulk. Ergonomy can be a nightmare if you go cheap and decide not to have an 'analog knob' level control ( real or only for control of digital) to manage the multiple chanels ( and a mute function too if possible).

Given the design of the LS60 Wireless, if any part of the built in electronics die, and cannot be repaired / replaced, then we are probably looking at dead speakers too?

If the parts are modular, and can be purchased and installed by the user then that gives some piece of mind.

2 years warranty on the electronics for a "premium" item sounds too short.
