Hi All,

Can I have your opinion on the KEF LS50 Wireless II + KEF KC92 sub (with wireless adaptor) Vs. Buchardt A10 Speakers + Buchardt SUB10? I'm not the biggest fan of WiSA but I am a big fan of active speakers. I don't want to play the component integration game. I like to play fairly bass heavy music (electronic, dance) jazz and soul jazz with some small group classical around 85db max in room, and am very sensitive to poor quality bass and poorly integrated bass. Source is streaming via Roon primarily.

My listening position is 3.1 meters from the speakers.


I currently have the Buchardt A10 Speakers + Buchardt SUB10 in this room and demoing the system. I like it but it feels like at higher volumes it is suffering, perhaps this is the compression / distortion that has been measured by Erin? I'm not sure but at higher volumes there is something I don't like where overall details are smeared. I'm using the Buchardt room correction software which only corrects fro 20-1000Hz.

I'm even considering a pair of Dutch & Dutch 8c. This is an entirely different expense level I realize. I've also read that the D&D 8c do suffer at higher volumes as well. How is this compared to the Buchardts?

I'm open to other options as well.

The main listening area is roughly square, with a hallway attached in one corner connecting it to another small room. There is no door partitioning the listening are to the other small room.

1. Dimensions of Listening space:
• Length: 12 feet 10 inches = 12.83 feet (3.91 meters)
• Width: 11 feet 6 inches = 11.5 feet (3.51 meters)
• Height: 9 feet (2.74 meters)
2. Volume Calculation:
• Volume in cubic feet: 1326.22
• Volume in cubic meters: 37.62

1. Combined Dimensions of listening space + space connected by short hallway without a door:
Length
: 25.16 feet (7.67 meters)
Width: 11.5 feet (3.51 meters)
Height: 9 feet (2.74 meters)
Combined Area: 289.34 square feet (26.91 square meters)
Combined Volume: 2604.06 cubic feet (73.73 cubic meters)

Compare their Harmonic Distortion and Compression (Response Linearity) data:



You may want to look at something that's not struggling to get down to the hand off to the subwoofer at high volume, depending on what crossover frequency you are using. With the Buchardt the THD looks good, it is just that the compression is struggling at 96dB (which is very loud). I suspect that the protection circuitry is kicking in.

I haven’t tried the Buchardts but I do have the LS50s and KC62 and the D&Ds they really aren’t comparable ot least in terms of price .
If you could afford the 8Cs you would never need to buy another pair of loudspeakers.

I'd suggest measuring the frequency response (with MiniDSP UMIK-1 and REW or even an iPhone with HouseCurve) to find out what you don't feel right. 85db in your room size shouldn't be too demanding.
