    Wow those 8C's are expensive!! They look pretty awesome though and the stated performance is incredible!

    Just finished reading the thread from start to finish, great documentation and super nice build! Not sure how old you are but there's a good chance you will have lost all of your hair before your barber can fully repay this.

    Have been away for a while, needed a break to recharge. Picked back up on a project started over a year ago and hoping to add some details about the build to the forum soon. Looking forward to more of your stuff, keep it coming.

    Wow! Looks fantastic! I bet people don't think these are DIY.

    Spot on. Most of our builds are “prototypes”.

    Build once and move onto the next project. Here’s my last project from a decade ago.

    Excellent work! It’s a lot of fun following your build threads.

    That reminds me of a thread on diyaudio where Martijn Mensink shared his explorations with cardioid and constant directivity designs. About about six years after the start of that thread he formed Dutch & Dutch and released the 8C.

    Thanks Geoff, that's very kind feedback!

    Yeah that's very very broad, mostly ignorant statement that quickly gets me upset hahahah. I can sort of sympathise with where it might come from as there is a plethora of sub-par DIY examples even on youtube that make me shudder. But the people making that statement have clearly never looked beneath the plastic coated chipboard of a commercial offering to truly understand what they are buying. I would go so far as to say that in terms of a well designed "DIY" by someone that knows what they are doing you will always get a better result dollar for dollar against commercial. I would honestly put the above bookshelves up against any other two-way bookshelf I've ever heard regardless of price.

    Fit and finish just comes down to the skills and resources of the individual. Lets not forget that in a large majority of cases we are looking at someone's first and only attempt. If I was to put the above into "production" even in small quantities there are A LOT of things that would be improved and ironed out.

    I've been looking at another DIY audio site where some people have said that DIY speakers can never sound or look as good as commercial: looking at these, plus the two ways you did with the RS180s, I have to say 'what a load of b - - cks'!

    Well done

    and yes I know it's completely pointless and a cliché piece of music to boot but here's a little sample I recorded on my phone. It does illustrate the sort of tonal balance these have anyway...

    A quick final update on these. (Was in the US for the last month hence lack of progress!)

    They have now been delivered to their deliriously happy new owner and I am kind of sad to see them go. I was really enjoying listening to them. They have such a smooth rich tone with bags of detail underpinned by a bass performance that consistently sends eyebrows flying upwards beyond the limits you would have considered possible for eyebrows to go!

    Here's a few final photos.

    I added a small recessed base to them which gives them sort of a floating look when sitting on a desk/shelf

    Oh absolutely. Those are awesome. They look even better assembled with nice parts. I might try that eventually - I just want to get these ones out of the workshop now as they were an unplanned project!

    However, can't make the thought of building another set of these taken to the next level with better drivers out of my head......no..no no...must finish other speakers first!!

    If I remember correctly the op stated that the xover was at 1800 or 1850 hz and the woofer cone breakup occurs at 4500 hz according to the published specs. The op could easily be prejudiced as it appears to be his design.
Working...
