I'm beginning to think Alpair x.2 especially special-order Sibelius' may have much better bass extension than Alpair x.3. Maevan my own 2nd-hand well-run-in Alpair 5.2 in 3.75L TLonken out-bassed Joseph RM7XL ~20L BR in >5x5m room (and presented a deeper soundstage than Monitor Audio Studio 2). Once I accidentally hit play without any upstream attenuation at all, right at Engleskyts organ closing climax. The 5.2 were extremely loud (and unscathed).
Very true. Bass extention was traded for greater sensitivity and better midTop.
A5.2 and A5.3 have the same bass extention.

I've covered this many times in the past, which will be buried in various threads on this forum & elsewhere; speaking factually (this isn't a matter of opinion) the only difference between Alpair 5.2 and Alpair 5.3 is the VC material. The former ran a CCAW coil; at the request of Norio, MA's ('our') Japanese distributor and part-owner, it was changed for a solid copper coil of almost identical mass and became the 5.3. There are no other differences at all.
Also for this diffraction treatment, prefer original tuning

Try listen a couple of days because you are probably biased for the original sound. With that said - use what sounds best.
Try set the filter for 30 Hz.
Ok, will try again. This dsp control is actually very interesting. The WiiM usb/sub update was only recently released so just checking quickly 🙂
Acko - you could try some baffle step correction with your Sibelius .
Print: shelving = 400 Hz , gain = -2 ( or try + 2 ) , Q= 3.
This will give you some freedom to move the speakers out from the backwall. The advantage may be better stereo image.

Tried many times but still can’t tell the benefits of this DSP treatment. I guess in a well designed speaker system there is no need for any tweaks. The only useful one is the sub out function where the main speakers are relieved of low frequency excursions, some of which goes down to infrasonic levels…causing unnecessary cone movements. Maybe others can try and report their experience also🙂
Yes , this might be a benefit using the Sibelius speakers.
Using the 24db/ oct highpass option in WiiM ultra , set at 30 Hz you are probably able to play about 3-5 dB louder above 30 Hz and the bass will have audible lower distortion. The bass performance below the box tuning frequency offer no backpressure protection of the driver without highpass filtering, making it move uncontrolled below tuning frequency, so technically this is a good thing. This is the case of every ported speaker - they really need a steep highpass crossover just below the tuning frequency.
Theres always a trade off though, because all filtering brings some phase shifts - the ear must always be the judge .

Very true. I had a subwoofer with a boost box that basically was a high pass filter at tuning. The sub was more effortless when not trying to reproduce the super low stuff.
Now, would the benefit outweigh the hit in transparency to the Sibelius ?
That would be up to the user.

I have been asked about my experience with the Sibelius and I must say it performs as promoted without the need for any sort of EQ (at my place). Pretty happy with it and lately been enjoying music that in the past I didn’t quite like but now with all the details coming out it is like a whole new experience. Unfortunately price gone up by 30% recently 😣

For those seeking to do an homage to Harley's loudspeaker, this interview might provide some useful info.
In other news, resident luminaries Scott and Dave got a shout out (aka design credit) from a new company producing a MarkAudio-based work of art, the Eastern Bay Sound's Southwind.
Great stuff.

I get no (direct) credit for this one, i did help with one theydecided not todo. Scott had someionvolvement, but thisis mostly nHarley’s baby.
