I previously had the KEF R11 but switched to the LS50 with two subwoofers. Subjectively, the LS50 setup delivered better sound quality. Since my room is about 25 square meters, I didn’t need the extra SPL that the R11s provided. Now, I have the LS60 with one subwoofer, and so far, this is the...

It’s fascinating how subjectivists in the audiophile world often dismiss scientific reasoning—until it happens to confirm their beliefs. When an argument or study supports the idea that expensive cables or components improve sound, suddenly they’re eager to engage with "science." Yet, when...

Hi everyone, I recently came across a video making several bold claims about how cables and timing affect audio perception, and I couldn’t help but approach these assertions with a critical eye. While the video was full of fascinating details about the complexity of the human auditory system, I...

A bit unreasonable? This is extreme snake oil at its best :)

I already converted to EUR, its 431 990 kr = 38 493,21USD

This is just to much, 43,199 EUR for a speaker cable: https://www.referenceaudio.se/produkt/jorma-design-prime-hogtalarkabel-bi-wire?variant=30691 Product description: Jorma Prime established Jorma Audio as one of the most respected high-end cable companies. Launched as a “no expense spared”...

I just posted a follow-up, and from the new measurements it’s clear the WiiM algorithm can be highly effective. The reason for the excessive boost below 100 Hz in previous tests was almost certainly the iPhone mic’s natural low-frequency roll-off, which WiiM most likely don't currently account...

Follow-Up with Umik-1 Measurements I revisited the Wiim RC measurements using a iPad Mini (borrowed from a friend) in combination with an Umik-1 microphone The measurement procedure remained the same as before, relying on the REW MMM (Moving Microphone Method) to capture averaged in-room...

I'll contact KEF to confirm. I'm using the LS60 with a preamp so I want put the LS60 unity mode, it should ensure that the LS60 does not apply any additional DSP volume attenuation or gain beyond its default calibration.

My goal here isn’t to “correct” the speaker itself but rather to address the influence of the room—what we typically refer to as room correction. Even high performing speakers, like the LS60, can’t compensate for room modes, boundary interactions, or other acoustic anomalies caused by the...

Only for time alignment between subwoofer and speaker, not for measurement for RC

Ok, thanks! If that’s accurate, it’s a bit disappointing, as I based my purchase of the LS60 on this information. I understand that my use case is likely in the minority since most users rely on the built-in streaming of the LS60. However, I would expect accurate information in the manual from a...

Understand, but sometimes some KEF representative are not in sync with facts, one in USA said that KEF speakers don't sound good with class D amps, although KEF are using class-D amps on their own speakers.

It's the same software and also in the actual manual for the LS60 so I've hard to believe that its a mistake: https://data.heimkinowelt.at/d/bed/k/kef-ls60-wireless-bed-a32913.pdf

Subjectively, the difference in my room is night and day. With prominent peaks at 20 Hz, 60 Hz, and in the 100–250 Hz range, the LS60 struggles to perform at its full potential. The sound becomes boomy, with the exaggerated bass masking the clarity of the midrange and treble. KEF’s goal of...

The manual för LS60: https://international.kef.com/pages/ls60-wireless-faq A2.4. How should I set the speakers if I prefer to adjust the volume on an external equipment (preamplifier, streamers/multi-room systems) rather than through the KEF Connect App? In the KEF Connect App: 1. In Settings...

Well, I agree that using a dedicated measurement microphone is ideal. However, in this scenario I wanted to highlight potential drawbacks for the average user—who most likely doesn’t own a specialized measurement mic—of performing full-range room correction with an iPhone. As shown, it made my...

Did finally buy the LS60 and its working really smooth with the Ultra. I've created a new thread with the set up and comparing Wiims RC vs REW MMM here: https://www.audiosciencereview.com/forum/index.php?threads/kef-ls60-room-correction-showdown-rew-mmm-vs-wiim-ultra—a-data-driven-analysis.59795/
