    Default 3.1TL Terminal Cup upgrade & AI-1 Build (finally!)

    Boy when I went in on the group buy for the Avel 1000VA that it would take this long to assemble it. I just used a old speaker wire secured into the pin for SDA signal. So this was a nice upgrade. Will be nice to have freedom when choosing amps in the future and to have a proper connection for SDA enjoyment. I also coaxed myself into "blinging" my speakers if you will with the nice polk aluminum plates Trey (Vr3) made. I like that they are unique to some of us here. In the end, I really dig it! Thanks for helping me spend my money Trey!

    So the other half went out of town to her parents place for the night. That meant a trip to the liquor store and time to do the mods. This was new in my favorite section...



    Started early in the afternoon and boy... gooooood stuff. Enjoy some pictures...





    Damn rights Jesse (F1nut) can't have all the NL2/4 fun to himself! For reference: The cable used is MIT but is temporary



    Binding Posts stay to the left!








    The washers for the bindings posts are very picky about how much you tighten them. I broke a couple but fixed with a solution.

    Was a great evening of drinks with me and my speakers....



    Now for the finished product:




    Everything is burning in nicely. SDA sounds much better already.

    Also something else I discovered when I began this project was when I went to loosen my PR, it was fairly easy. Upon fastening everything up, I was able to turn all my MW screws an additional 180-360 degrees and some that even turned more! Shame on me for not going back over them after I first tightened them down the first time. But I went over both of them and they are definitely coupled now... I just want to state something Jesse said once... don't need no stinkin' subwoofer!

    The last mod is the crossover upgrades and those are in progress. And they wont disappoint.

    Everything turned out great Andre!!! Looks like a million bucks! Excellent work!

    You are going to hate this next line though - I would put hot glue around the perimeter of the NL2/4 cut out just to make sure it is air tight... :)

    Cant wait to see how the crossovers looked installed!

    I wondered if anyone would say something along those lines. I actually was going to use my girlfriends hot glue gun but there are no refill sticks for it. Not hard to pop out and do. :) Good eyes!

    Also, a good replacement for those nylon washers is a 8/32 nylon nut :)

    Real quick.....I would not use hot glue. If you ever want to remove the plates it will pull up/tear the covering on the back panel. I'd try the Armacell gasket material.

    That said, job well done! Looks really nice.

    Why temporary?

    It looks like he did put the Armacell around the new plates. I think Trey was just saying to put it around the SDA connector (NL2/4) on the inside to ensure air doesn't leak out around that connector point.

    It does look nice though! Makes me want to finish off doing mods to mine. No time at the moment though, so I'll just have to watch everyone else for the time being.

    Ugh, my reading comprehension failed me on that one. Thanks!

    If you did use armicel why are there splits in it? If you put the spits in it you don't have to do that, just pull it around lightly it will compress just fine if not better..

I can only space my speakers 6 feet apart (inside measurement) at the most currently. Once I move, I'll have lots more flexibility.

    Like my MW's, I found cutting slight slits frequently along one side helped with curving the gasket how I wanted. When compressed, the slits compress into one another and there is a solid inner circle that is untouched. I'm confident it seals without issue. I made sure to go back and re-tighten down after compression. The only minor air leak is from seeping through the NL2 and binding post holes. Some hot glue will be applies to the inside seams of each connector including a good dump on each binding post nut to make the plates air tight.

    However, my MW's tightened up when I actually went over them the other day and found they were all in need of of more clamping force. The bass is unreal now... Can't imagine what the 2.3 or 1.2's would be like...

    A little more bling. ;) I'm surprised Trey hasn't posted on the build yet...

    Crossovers will feature Clarity Cap ESA build for Tweeter, Mids and SDA circuit with Mundorf Mox resistors and Jantzen inductors for everything. All on Gimpod boards.

    and thanks buddy for the comments!

    The recommended spacing is 6 to 8 feet apart. You'll never need or want to space them 16 feet apart.

    It is my understanding that to properly set them up, that they must equal the same distance apart as they are to the listening position. It's even diagrammed that way. I think IMO, that they sound great currently spaced apart (6 feet) for the distance I sit at (9 feet). But that is subjective as I keep telling myself that even though it sounds good..., not great, but it's still wrong.

    Interesting points you bring up though.

    Yes it is, but......I've found they sound better exactly like you have them now. Of course, it will vary with the room, but in my old house and the new one (very different rooms) I didn't like the presentation when set up equal distance. Another example, years ago I had a friend with SRS's in a fairly large room with the speakers spaced far apart. I'm going on memory, but I'd say they were between 12 to 15 feet apart. Sure they filled the room with sound, but the sound stage and imaging didn't seem right. I convinced him to move them 8 feet apart while keeping the sofa where it was, which was about 12 feet away. His face said it all. Anyway, you'll figure it out when you get into your new place.

    Andre, nice work. Congrats on finally getting your Dreadnaught set up! Can't believe you waited so long, mine was ready the night the transformer arrived!

    One question about the screws you're tightening down. Wondering if you're using Larry's rings?
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    There is a practical limit they can be set apart, regardless of the distance away you sit. Experimentation is the key within your room, but 16' is going to be too far apart.

    BTW, nice work!

    Thanks for the advice guys. I suppose I'm not being practical on my cable length needs as far as spacing the speakers.

    Great story. I've tried listening to them in a "proper" distance and I didn't like it at all. I agree with you remarks about placement cause we currently are in a 100+ year old house now.
