They look interesting, Hedd ‘main towers’ next though (probably/possibly) depending upon how they sound.

If anyone spots anything ‘interesting’ please do let me know, I am always keen to explore what is possible.

They don’t make ‘Madge’s greatest hits ‘ sound any better though.

Joining my active collection, Meridian M10’s, I owned a pair of these from their release in 1984 until the early 2000s when I foolishly sold them.

Synergy horns. I'm sure there are already UK installations, but I haven't seen a domestic installation anywhere in Europe. Coaxial dispersion but much much less limited in SPL than the KEFs and Gradients of the world. Polar from their spec sheet (Danley SM-60F):

I think I mentioned it to you already, but in light of the addition of the HEDD to your line, the KS Digital C5-Reference could be very interesting. It blends some features of the HEDD with the Gradient speakers, and I haven't seen it discussed/used much in the English-language market despite being sold on Thomann. It uses a 6.5" SEAS OEM coaxial, similar to Gradient's 1.4/Revolution (though spec'd differently). It's sealed, active, made in Germany and has FIR filtering to linearise phase (like the HEDD). It's in a mini-monitor format (steel enclosure that can be angled; slightly larger than LS50), and surprisingly well-priced given all these features. Measured performance under very demanding anechoic conditions is +/- 1dB from 250Hz to 9kHz (+/- 1.5 from 150Hz to ~9.5kHz), with linear phase at the crossover:

Graph trace of the graph above (high treble dips are inherent to SEAS design, inconsequential and Gradient has it as well):

Their own specs:

I've spoken to them before and I've been quite impressed - similar vibes to HEDD, willing to make relatively innovative speakers in Germany at a surprisingly affordable price.

Are you sure those C-5 are sealed? Because that slit at the bottom back looks like a port to me.

I stand corrected, it was too dark for me, thought it was part of the stand.

Grimm make Three versions of the LS1 I believe the most expensive Be version with motional feedback subs is considerably more expensive than the 8Cs .

But Grimm also has a cheaper version LS1a, how does it compares?

Grimm didn’t release measurement for every model, I assume they are the same?

I have only ever owned the original LS1 and the ‘top of the line’ BE/ motional feedback version, but I wouldn’t expect there to be a huge difference between any of the models.
