Monacor Coax driver - SP-312CX used in a MLTL cabinet.
Mine are the Speakers that have been produced as a personalised design by the individual who built a selection of these models in a 10" Coax version.
If these are of interest I can guide you to the Build Thread.
This is a very very affordable way into experiencing an End Sound that for myself has become very very attractive, so good only the 300B's have driven them, the 845 Mono's are Ornaments where these speakers are concerned, maybe this will change during the Holiday Period.
My Calc's are approximated to +/- 20%.

If a Speaker sharing similarities in their design from a well exposed Brand was to be used as an A/B comparison, using the cheapest build method from the above, purchase prices for comparison speaker will be found to sit between $8K - $20K.
If the more expensive build option was selected, purchase prices for a comparison designs can easily extend by another $10K.
Fyne F1 ?? Models are where comparing sound will be at a good starting place.
