For me it is the wrong approach to look at the speakers first. You should first develop a concept for the existing space in order to first optimize the potential of physics. Because DSP, room correction software and Dirac ART, for example, cannot completely solve all problems of room acoustics...

Thanks Amir for the great review. I like the approach of looking at multiple trendlines and filtering them individually.

"We added a new Beryllium tweeter, which was co-developed with Seas. It extends the frequency range and has 9 dB less distortion than our original tweeter." (https://www.grimmaudio.com/hifi-products/loudspeakers/ls1be/) It does not tell what kind of distortion, but I guess their statements are...

Maybe first a good mic to make some measurements in room.

I just want to mention, that for example the Seas Excel Woofer W22EX001 cost a bit more than 200€ per unit in Germany, when I first thought about to build the LS1 by myself. For the DXT tweeter the price was approx 50€ each. At the moment the woofer costs more than 400€ and the tweeter also...

I have posted very few here https://www.diy-hifi-forum.eu/forum/showthread.php?22311-LS(de-Mar-)1 . It‘s a german forum. I didn‘t documented it very well, but i can look for some more pictures. Edit: More Pictures…

I build a LS1 by myself. Obviously my interpretation of the design is a bit different. One design goal was it should look independent from the origin design and fit my taste :) . But nonetheless i stick to the origin dimensions of the original. Because of my design decisions, i had to put the...

Driver could be used in between a tweeter and a big woofer, to make a nice three way speaker.

Behavior of distortion seems to be similiar here: https://www.erinsaudiocorner.com/loudspeakers/jbl_scl-6/

The Video was not boaring. It was really entertaining and educating. I was never aiming to get one of these products, because i think room accoustics and speaker design should be the main focus. Solid engineered amps and dacs complete a proper working system. Nothing more will dramatically...

Really nice concept. The combination of DXT -Tweeter with max. 6“-7“ midwoofer and the right choose of the baffle design has outstanding directivity behavior. You should have a look at the speaker concept of Alexander Heissmann https://heissmann-acoustics.de/en/dxt-mon-182/ . He has no Klippel...

Is‘nt especially the correlation between measurment and listening interesting?

Thanks. I thought the impact of the DAC would be bit higher in the chain of a multi channel or stereo speaker setup.

A big advantage of these „pro“ av processors is, that you can adjust a lot manually. This helps, when room and speaker setup isn’t optimal. But i guess, when you do the right speaker set up (positioning) and room treatment, the difference between a good av receiver such Denon X8500/X6700 and a...
