So the stuffing is done. And the backs have been glued on. The sides at the back have been routed flush. Holes were cut for the terminal cups and a wire put in before gluing the backs on of course.

Now just routing the bottom edges uniform before cutting the breathing slots.

So I finished the bottom pieces with 2" plastic pipe. I cut the lengths to around 5.5 inches - being a compromise between the EL-70 and CHR-70.

I held the speakers upside down to saw for the breathing slots, cutting to the depth needed minus radius of my router bit. Then I used a finishing router bit to route the breathing slots, using the screwed on bottom pieces as a guide for the router bit.

Now the basic construction is done - next step is sanding, tidying up, staining and varnishing.

Progress....

The bottom pieces were finished up and mounted into the base of the speakers. A couple of coats of Dark Walnut gel stain and they're starting to look ready for action

Thanks Sippy!

Well they are now in song.

And for the first time I understand why people rave about the bass of these drivers !

The photo shows the Martello-2's flanking my new Big'un speaker. They don't compare with the AN15, but they do a very good job of it.

I'm not sure I'll need to be doing any tweaking.

This could be a case of "It's a wrap!"

Two drivers per side - that would be really nice !

Anyhow, I'll listen to them for awhile. No doubt I'll find myself wanting to go back to the AN15 eventually but they do well for their size.

I now have it on good authority that the WAF factor for these speakers, being narrow and not too tall - is extremely high

Bigun my friend!

It's not that hard if you use a Swanson square as a guide. Freehand you have to be either a miracle worker or an idiot to try.

I used a guide, a piece of wood clamped on top of the piece I was cutting and ran the edge of the baseplate of my circular saw along this guide. But you know, the slightest wobble of the saw and the cut is slightly off. Over a 30+ inch long joint you have to be spot-0n for two of these 45degree edged planks to make perfectly. So, I'm afraid my workmanship just ain't up to it !!! - but following-up with the router made things 99% good.
