Wesayso,

Kudo's to you for an amazing endeavor. I'm one of those, likely many others, that follow various threads from time to time with interest. Yours has been one of them.

No need to say more about... next steps... you've had plenty to wade through.

I would however like to offer this. Being somewhat new to on line forums, it's been disappointing to see some of the bickering that goes on. One's ability to agree... to disagree... is certainly a virtue for some. While my words won't lessen your disappointment and challenges, maybe there's a "Ray of Hope" in all this, there has been for me anyway...

It has been a breath of fresh air to see so many forum members come along side you, with genuine concern, and offer help. The human spirit can be good, and this has been a great example of that. Some may call this naive, I prefer to call it hope.

Good luck in your journey..many are cheering you on.

Kindest,
Marko

Hi wesayso,

Just wanted to pop in and say hi after catching this thread on the main page and enthusiastically reading every page of it! I haven't been getting notifications from the other thread (stupid cheap line array) so I missed out on all your progress!

Your work with these is nothing short of astonishing, and the finish you've achieved is possibly one of the nicest I've ever seen... including those found on the best boutique systems.

I was reasonably proud of how my arrays turned out, but this is a whole different ballgame! Your work makes my arrays look like some sort of primate made them. I even showed my wife this thread and she was floored. She told me I had to rebuild mine... thanks for that :S

As for the crack, I'm sure you'll figure out a way to solve it. My personal guess is that you need to get those bolts out, and some of the suggestions of tightening one end a few millimeters a day until the glue holding the rod gives out seem like a pretty clever idea. For what it's worth, that would be my path forward.

Worst case is you'll have to refinish the one that cracked and hopefully the other one lives through the bolt removal without splitting. Redoing work a second time is never fun, and I've been there many times before, but if you consider the amount of effort to get to where you are now, it's well worth it to maintain that incredible finish the way it is now.

On another note, have you settled on what you're driving them with, and how your final EQ will be done? Mine are still in full service in the living room in our new house, and with some minor EQ tweaks they are sounding as good as ever. I hope you get yours finished up so you can enjoy them as well.

All the best with this project, and I'll be watching from the sidelines!

Regards,
Owen

(not my house, just an example of the look)

So either that or neoprene...

To Mark:

Thanks for your thoughts and I agree. This is one of the friendliest forums I have been on. And I am impressed with it's members, not only the big names we have on here but the helpful people around that encourage you to go forward.

To Owen:

Glad you found me . your comments about the wife made me laugh. Maybe we need to swap (lol) my girlfriend is into a white phase right now. All accessories in the house are slowly replaced by white items, sort of this weathered look:

The decision on the rods will come in time. Not making up my mind yet on what to do. I'll continue to observe what these enclosures do next.
I'm sure I'll find a way to rescue all my work so far. I'm just glad to get this much help here, I won't rule out the possibility to do this again someday and there were some good suggestions thrown in on how to do it a next time.

My primary EQ for music will be from within JRiver Media Player. Possibly with a plugin, will do some tests. My secondary sources will use the Behringer DEQ, I'll even mod the analog input and route the digital out to a separate DAC. Most important to me is to have access to separate left/right EQ, if my Car audio experience, where you sit way off axis in a very reflective environment has thought me anything.
But there will be some tests I'm sure using digital in on the Behringer as well.

Ahhhh, that stuff - strip caulk.........
Leave your speakers alone and play with that stuff for a few days
I've got lots of that stuff on rolls, very handy stuff indeed.

Weathered look = Shabby-Chic

After all this commotion lets return to our regular scheduled program...
I'm drawing up the aluminum baffles to have them made for me.
I want to optimize the flow at the rear of the baffle a bit but not to the extend that my friend will be mad at me to have to make it.
I'm thinking of this:

And similar for the front baffle, a little different than I had it due to dimensional changes:

I can have these made like this and keep my friend happy. I'll make the drawings for production next.

Also did some work on the test enclosure. Almost done, hope to do tests early next week. It looks like this right now:

Way too pretty for a test (lol). My girlfriend wanted me to use these instead of the towers .

Looking great.
Personally I would use a 45 around the back side of the baffle.
The more radius the better for reflections.Looking great.

Even your test pieces looks great. Make another and you'll have a great pair of rear surround speakers.

The MDF baffle is covered with black varnish in a nice uneven texture.
Hmmm, interesting...

Make the white stripes vertical - they would look like sticks of rock.
Would be a crying shame to paint over the existing finish imho.
