Kevin I admire your work. And I am looking forward to auditioning your floor-stander - when it's ready. Do you think it will have the new tweeter?Piano black is great for a good number of folks.Regarding wood finishes, I prefer in this order - sapele, all complex maples, oak and then cherry. ETA - is that opening at the top a bass port?

ETA - is that opening at the top a bass port?Thanks! I've put a lot of thought into the design and my CAD skills are marginal so it takes me too much time to model things. That is just part of being a Jack of all Trades and running a business. Yea... the top is the port. I was looking for a creative way to keep it on the front but I didn't have space for it on the baffle so it ended up as part of the top. Area wise it is 25% larger than the current port I use on the Kepler so it should be completely noise free. And yes... this will use the new Exodus tweeter and a 6.5" midwoofer. It should have bass response into the upper 20s or low 30s in-room. The tower will use an 8" woofer and will have a -3dB of around 25Hz in-room.I'm going to have a fairly limited selection of finishes. I was thinking Piano Black but to be honest I'm leaning more towards a BMW Metalic gray that is very dark and looks pretty sexy. Everyone has black and like black, the metalic gray would fit almost any interior scheme. In terms of wood I was thinking of a dark walnut.
Will the baffle be wood or a black something?I'd vote for wood for the wood finish one.
I like the top mounted port - reminds me of the old Battlestar Galactica cylons! A red LED in there...As for colour choices, the grey would be classy, and likely fit well into modern decors, but I think the gloss black is a classic that would also fit well. Wood choices will always go better with more traditional decors.Make mine a kit, and I will do the flat black myself!Are the driver's video shielded?
The overall shape of the cabinet reminds me of Wilson-Benesch, but the overall looks don't. It looks like the cabinets are a bit complex to make. I am assuming you are having them CNC made? Have you considered faceted baffles? Just a thought given the extent your going to. Piano black is popular and light woods tend to be popular although I like dark woods.
Very Nice work, Kevin. I wish I knew how to jockey 3D CAD software...A top-mount port should work well in a bookshelf design... especially if you TL load it. Hmmm... You might (and I say *might*) get some "lobing error" phase cancellation issues if it is too far away from the woofer, depending on the tuning frequency. But a small bookshelf TL might sound sweet.
That top port looks a little tricky. It will certainly need to be of thicker material, otherwise it would chip and crack. Perhaps if you made it of a pre-formed plastic type insert? Don't know, but I bet people will be using it as a handle to pick up the speaker if you keep it on top like that, so it's got to be strong.Bob
I think there are too many complex surface shapes and transitions around the top/baffle junction. The top surface should make one smooth curve down towards the front, with this curve transitioning to the same radius as the sides of the baffle before reaching the front. This would have the dual function of dissuading the use as a support for potted plants.I think the bottom of the baffle should have minimal rounding - it looks awkward looking down as in the top picture. The top port is a great idea, but the edge needs not to be an edge - it'll break too easily. This design would make easy a port refinement that usually is too awkward to implement - a variable length. If the opening were not straight across but had a V shape (that is, further from the front in the center, or like an arrow pointing aft) the tuning would be slightly smeared across a frequency range which might be to advantage, but at least makes good copy! If done right, this would make it more difficult to use it as a handle.
