New Build: Coniston^2 dual driver double mouth MBVR
 
Upon receiving my EL70 drivers from Bob I cut two batches of wood. The first was for the Thirlmere dual driver single mouth MBVR. I tried those and at first was not impressed. As time went on and the drivers broke in a bit (and I got better at placing them) they sounded significantly better.

Since that time I've had a very full schedule of things to do and I'd forgotten about the second pile of wood I'd cut in my garage. This wood was intended to become a pair of Coniston^2 MBVR speakers...(pdf plans from Dave's site below)

I'll document the build process for these as best I can with the appropriate pictures throughout. Now that I've gotten the motivation to start things should move quickly since I don't like leaving things unfinished.

I'm expecting great things out of these. The Coniston^2 design is very similar to the Lotus^2 that I favor so much so I'm anticipating results that are also similar. The Lotus^2 speakers were happy in a variety of listening environments and didn't depend on placement quite as much as the Thirlmere set did so I'm a bit excited about how this will play out with the new set.

I know there is at least one person here who will give me crap for using MDF but it has it's benefits in my particular case. If I'm going to stain the cabinets I use birch. If I'm going to paint them I use MDF since it has a much finer/smoother finish at the termination points and is very easy to work with.


That's all for now; pictures to come soon! :D

Might as well get it over with.... you said you had found a source for good ply... you better have had those panels cut before you said that :)

You should build something out od each and swap em in and out for a while.

Yeah, I cut this wood about 3 months ago. That's how bad I've been slacking! Really though, if you've tried to paint birch ply with a smooth finish it's tough it's less continuous than MDF so it's a little annoying when you get to the painting stage.

I'm planning to do a build with the Mark Audio Alpair 12's next using birch ply but that's for another thread and another day.

Chris (i'm not allowed to build boxes anymore) is of the opinion it is easier to veneer than paint... MDF or ply

I've not tried veneering on my own. I really need someone who's experienced to show me first.

Here are some build pics of the progress so far.

A few more pictures to update on the current progress. I got them sanded and primed (once) and I'll repeat in reverse order (prime then sand). After which I'll put the paint on them. I'm hoping for a decent finish. I really hate painting; have I ever said that?

Wow, the footprint is really small. Looking forward to hearing how they sound!

Can someone tell me what the expected advantage is to have two Mark Audio EL70s in an enclosure? What difference between the twin and a single enclosure? Does the extra speaker firing off to one side give a bigger sound field? more bass? I'm thinking of the Conniston of course. I built the G changs last year (which I think are great) also the Jordan transmission line enclosures, so I don't need more speakers in the house but need and want are two different things aren't they?

Here is the latest picture of the progress. Sorry for the delay in my work (multiple projects at once). The color scheme is to match a certain room. My friend owns a hair salon and their place is all black and white. The cones of the EL70 are black and so is the basket so these should fit right in at his place. I'll run these for a month or two and enjoy them before I give them to him though :)

Drivers should go in soon once the paint fully dries.
