Let’s talk Tower Mains
 
Hello Klaus&Freddy,
I wanted to ask how the Tower Mains differ from your MK1 and the new MK2 series.. despite being a closed design and a much bigger cabinet/SPL capable.

- Is a totally analog design, not dsp based?
- Are the tweeter/components the same like in the Type20/30 MK1/MK2 series?
- Is the waveguide of the tweeter and are the mid drivers the same like in the Type20/30 MK1/MK2 (despite the obvious config difference)?
- Are the drivers made in house, despite the AMT Tweeter?
- How does it compare with your MK1/MK2 series, soundwise?

Thank you!

Best regards,

Cheu

Hello Cheu,

so here are my comments:

- yes Tower Mains are completely analog
- TM 80 has the same drive units as 20 and 30 MK2
- The waveguide is very similar to MK1 monitors. The 20 and 30 MK2 have a somewhat wider waveguide that improves the horizontal dispersion in the >10 kHz area.
- AMTs, including the full range AMT for the HEDDphones, are made from scratch in Berlin. Woofers and midrange are designed in house and made in China, the cone material that we consider to be decisive for the sound performance has been defined with a corresponding manufacturer.
- no driver has been changed for MK2 series, filtering including linear phase filtering now is done by DSP.
- Soundwise it matters that the HEDD Lineariser® is now on board, transients and three-dimensionality are audibly improved.

Greetings

Klaus

Thank you Klaus!
Tremendous job on the integration of that amt tweeter!
