Is anyone working on an MLTL for the CHR-70?
Anything to share or report yet?

I have 3 ML-TLs in the queue. Chris should be bringing proof-of-concept boxes up for the cutest ones (& the biggest stretch) Saturday. These will also work with the new EL70 with just a change of port.

The others are large & larger. Each will have a full set of variations.

I have a MLTL design and have built prototypes for the new EL70 as well. As Dave suggests changes for the CHR-70 would likely just be a port tube alteration.

I took my EL70 MLTLs to the Dayton DIY event on July 11th. The EL70 MLTLs are the walnut speakers on the left of the photo next to my Mark Audio Alpair 10 MLTLs in cherry.

Nothing to forgive, I did a DIYaudio search and these three posts are it, so apparently Dave, Jim and their associates are the only ones 'in the know'.

Bob announced it yesterday. http://creativesound.ca/

A paper cone driver using the same basket as the CHR70. Will be sold as a CSS EL70 with a limited number treated and sold as P10 EL70eN.

There are a wealth of designs nearing completion for this driver (one of the reason things like the CHR ML-TLs have been delayed)

I will limit my comments to that for now.

I was wondering if anyone make a Bass Reflex for Alpair 10 Fullrange, i believe its still good enough providing a possible faster bass than the ML-TL

I've heard them *) at home on an transistor amp (HT amp) and on a DIY event driven from a small tube amp, and it was clear that the latter was the better combination, realy outperforming much more expensive systems and even convincing "non-FR" audiophiles of the quality of a modern full range driver.
