Mark Audio CHR-70 Application Thread - Page 26

Thanks for your reply Henkjan.

The reason I ask, is that at home using them in a marine ply version of the Mark Audio Pensil 70 TL design I initially thought the speaker was a little 'boomy' in the bass end.
This was using a Tripath based amp. But, after changing the amp to a PP triode connected 6L6 and then an LM3886 based amp it seemed that maybe the smaller T-amp's are unable to damp the largish excursion of the cone in this design as well as the other amps. I haven't played that much with stuffing and positioning yet and noted this effect just changing between amps.

I suppose this is why HareBrained recommends the Dual Chamber Reflex design for the CHR-70.

Excited to hear about the EL-70 as I've heard what I thought was a little metalic 'Sheen' to the top end of some (not all!) voices while listening to the (not yet broken in!) CHR-70's.
At this point I've spent more time listening to these speakers through Tripath based amps and for memory don't think I noticed this 'Sheen' as much with the other two amps. Maybe my love affair with the T-amp is coming to an end?

With the valve amp and the LM3886, even at this early stage, these speakers sound BIG and detailed with more than enough clean bass for my mid-sized room.

GM,

The Mark Audio website seems to have 'broken' links at the moment. Have experienced this before - seems to be since they've recently changed the layout.

Here's a link to the plan for the Pensil 70 design:

I had it stored from a previous download. The MA site seems totally broken at the moment. I'll let them know by email.

We have just finished 2 variations of a microTower ML-TL for the CHR (and EL70)

I have started a separate threas as there are many variations.

microTower bipolar ML-TL for CHR-70 or EL70
