I can't see any connection between your praise of FM and trying out Hegel.

Incidentally, one dealer offers FM demo devices on audiomarkt.

When i buy FM i want the box with the big resolution series screen lit up .

FM lower priced gear is Single ended or a combination of both like the 245 pre amp but not fully balanced ( afaik)

So afaic it starts with a FM 411 mk3 with 256 RC pre amp , linearizer can be added later according to Manual Huber the linearizer is the " Thing "to buy from FM acoustics .
Afaik a 268 is a 266 with built in 233 linearizer

FM 411 mk3





FM 256 RC




Linearizer 233

I changed interlinks today .

The old ones served me about 20 years .
The new ones are slightly more expensive at 37.50 euros.
For 5 meters

But .....they have a anti interference filter lol

I ll connect the meitner with XLR as well see what the difference is.
Placing the meitner close to the Hegel .

SUBs casings were ready just picked them up
Made from HPL of course.
Internal stiffeners support internally the Magnet to reduce/ eliminate Resonance.

These are passive subs with internal low pass filter and can be used with any speaker when the sensitivity matches.

Sub sensitivity is 92 db .

If the main speaker has a 92 db sensitivity then each speaker needs a SUB.

If the main speaker has a 89 db sensitivity
.one SUB is sufficient

But a +- 2 db variation is acceptable because :


Speaker sensitivity can vary across different frequencies. 1 kHz is a common frequency for measurement.

Some experimentation .
It functions not strictly as a bass - sub .
It also plays higher freqs. supplementing the bas - mid freqs. acting as a centerchannel almost
Interesting sound ,it completely fills the innerspace between the main speakers
This is the 320 mm papersandwich / foam version woofer not paperpulp for extra stifness.

The signal i just take from.either the left or right speaker, best result is when the sub is exactly in center slightly behind the main speaker plane / equal distance to the listener

And the 12 inch Nomex kevlar woofer..
This is a fantastic woofer
