Hi Cat,

I used my typical “flash” techniques and discovered some leeks in that 50 years old enclosure. Sure it the leaks were there then it would be no “acoustic suspensions” and the driver would run further. So, fixed the box with the liquid wood and the problem with the Red’s “sinking” is gone.


Leaks were way more present in my enclosure...I also thought the general quality of the wood was too soft and much too audible for my tastes.  The resonances spoke over the music.

The dynamics is an extra subject. The HF driver does surprisingly OK in terms of dynamic. The LF driver is another story. The Reds in a right “untreated” box do their typical “primary resonance spreading” and it certainly do not give an impression of dynamics in the terms as we use to…

Agreed completely.  You know, it was the high driver that actually masked some of my initial dynamics needs.  It did not take long to realize the high driver was much better dynamically than the woofer, but I fell into, and still do, loving the speaker for its ~400hz to ~5k area.

BTW, it is interesting that you find the Golds and DMT's tonally challenged compare to Reds. Can you elaborate on it? The Golds need >150W to drive them….

150w!  My goodness...thats beastly.  The most I got on either of them was fairly friendly but room temp increasing 60W Pass labs and a mechanical Bel Canto (120w?) class D amp.  The golds did OK and similarly to the Reds, but they did need more power than the reds for dynamics.  Tonally, even if they could handle the higher powers, had more constricted tonality in relation to the dynamics.  It was like talking louder but using a bad capacitor in the line and low volume compressor at the same time.  Considering the 89-90db of the little golds, i can see why 150 could be a reasonable number.

The DMT's - I only know the 15 - are an oddball to me at this point.  Their tonality occasionally approaches barbaric with poorly recorded material, but the ease of the dynamics are really nice.  I would actually say the big driver is much better than the gold, but the highs are not nearly as lovely as the reds.  The box as well is front ported bass reflex which really takes away from a lot.  I have not played with these enough to really comment too much on what can be done with them, but they do need slightly friendlier sounding class a solid state amplification to work properly.

Best,
Chirag
