Speaker build - CNO4

Take a look at the Troels Discovery 861 floor standers. Very easy cabinet construction and simple crossover. I made a similar design with bottom vented base ports(picture posted further up this thread)and found they worked very well placed up against walls. Good luck if you decide to build something it is a very satisfying process as I’m sure Mark84 would confirm

Thanks for your comments. Very kind. I have also built a bookshelf with that same driver! Very good driver that 5 “ scan Speak!

No problem on thread deviation! We are still talking DIY speakers and my build is done! I couldn’t be happier. Pretty sure these are my end game speakers!

@Sparkymark Thanks for the tip - will check those out on Troel’s site.

@Mark84 Cheers Mark. Pleased the build has worked out for you, and not surprised they are end game speakers!

@frenchrooster thanks but this speaker would likely be a step down from what I have just built. Troels has plenty of high efficiency speakers with big drivers if I wanted to go that way. I chose to settle somewhere in the middle in terms of efficiency @ 91db. Also, once you hear speakers with a large amount of radiating cone area it is really hard to go back to something smaller… not sure on the size of that driver but it probably would not come close to my expectations of low distortion. I wish you could hear my speakers. 1”+6”+8”+12”- this amount of high quality drivers is really something. The Atom is just for now… I have my sights on a SN3.

The scan Speak bookshelf will be great up against a wall. However depending on what you already have may not surpass current performance.

End game bookshelf speakers!!
Scanspeak Ellipticor drivers. Troels built these on scanspeak’s request for the munch high end show to demonstrate their new drivers. These are on display at Scan Speak demo room in the picture.

But if you want something a little more affordable and compact for an office space…. This is a recent builder example of the seas 5”… just gorgeous!!!

Stunning! As are the Scanspeak Ellipticor speakers. Those speakers builds for Scanspeak look good, and a true endorsement for Troel’s designs if they commissioned him to create speakers for Munich - very impressive.

I have looked at the wall mounted speakers, but you echo my thoughts, it could be a sideways move! I’ll do some more research and consider my options. One concern is that if I do plunge, and they do not work out, then the relative monetary trade in / resale value of kit based speakers is not as great as their manufactured competitors. Lots to consider.

Fantastic work Mark84

One huge benefit of DIY is that you can adjust treble level to blend perfectly with the midrange to suit your room and ears…Troels labels as R1 in the crossover to be adjusted. Simply just soldering in a new resistor value (I always order plenty options with the kit). This is something you can’t do with normal speakers and is IMO one of the things that results in such an enjoyable sound. I spend quite alot of time playing with this… I like it silky smooth where I can’t pick out the tweeter playing at all. When you get it right the soundstage just all falls into place and it’s magic!

No problems!

Like most, I’m in awe at what you’ve built there. I can’t remember if it’s already been asked or even if you’re able to answer it but do you have an idea on just the raw cost of your kit (minus tools & time) and what would be the likely retail cost of these from a commercial speaker manufacturer?

Loving the idea that an Atom is producing the goods in combination with active bass amps.

This thread has really got me (and probably a few others) thinking about the whole approach to this hifi lark! :slightly_smiling_face:

Cheers, Rack.

Hard to say what they would compare to. I can only say what speakers use similar quality components. The Titan 808 uses a modded version of the same tweeter and midrange, also uses (apparently) high quality, low order crossover components but it doesn’t have the 12” bass driver and the plate amp. They do have the advantage of a team of engineers/ anechoic chamber etc though.
Total cost of materials for this speaker was about 3800 Pounds Sterling ish. That is converted from AUD though. Would be cheaper purchased from uk as you wouldn’t have the horrific FEDEX shipping that I had to pay!

That’s a very interesting figure. Obviously you have the work space and tools (wouldn’t like to guess how much that lot is worth). Just wondering if the panels could be cut at cabinet makers premises and then assambled?

Still wondering how you’ve man handled 75kg of speakers around the workshop on your own though, especially lifting them on to the worktops!

Plenty of gym :muscle:t3:
I used to make concrete worktops/ tabletops so use to lugging around big heavy things. Must be careful of my back though as not as good as it used to be. Had to use a sack trolley to get them from the garage and after fitting them out with the drivers me and my son had to put a towel under the feet and drag them across the living room into place. He is 11 so couldn’t help lift much!

A cabinet maker could definitely work with someone and help them out, for sure!

I was wondering the same thing. Curious what sort of cost that would add.

I used to use Avon Plywood who had a cutting service that included routing speaker recessed and rounding edges. They were always fast and accurate.
They have now been bought out and are now Sydenhams Plywood. The website suggests that they still provide that service.
Obviously you still have to put it all together. We managed using a thick sheet of ply on two Workmates on the driveway to build all sorts of cabinets.

Well Mark says his material costs are around £4k for a speaker that could retail for 4-5 times that (Kudos 808 level) so even if they they charged £1k you’re still well in budget.

Cheers, Rack.
