You are using the laptop’s monitor? That close the 4” CHR might be pushing it for closeness.

If you are going as large as 7.5 litre, my Classic Golden Ratio dCHR-Ken70 is only 1.5 litre larger. Frugal-phile | Box Library / Mark Audio

Yes, I sit here & surf the web on my laptop while listening to music via youtube. I am using a pair of Paul Carmody's "Hitmakers" from Parts Express currently. These were my first and only speaker builds thus far. They are about 28" from my ears. I typically don't crank them up very often though. My wife sits about 8' from me most of the time and she doesn't like loud music. I'm not all that fond of it either these days!
I like the look of your Slim Classic GR dCHR-Ken70 design.

Personally rather like Bermuda's own Gosling Black Seal in a Dark 'n Stormy (when you can find a decent not over spiced Ginger Beer) . The results are the same, but it doesn't have quite as scary a label

I don't have any way of recessing the face of the driver into the front baffle as shown on the plans. Will this have a big detrimental effect on the sound?

Generally yes. The big bezel of most of the Mark Audios is ideally rebated. Also important is to champher the back of the driver cutout (whether tidely with a router or crudely with a rasp). You can succeed by using 2 layers the top layer as thick as the bezel (6mm). The material can be cork or wood or felt (or layers of felt.

One more concern: the soldering of the wires to the speaker terminals. What's the best way to do that without melting the plastic pieces connected to the metal tab?
