I started a new project, ummm, months ago but my job got in the way. I was forced to sub out the cabinet build but there is still plenty for me to do. I'll start posting pics in the next couple of days. Stay tuned.  8)

Please do. I don't have the skill set to do something like this, so it's a lot of fun for me follow the progress that you and Rich are making

SWEET!!! Some DIY audio porn coming. ;) I love seeing behind the scenes build as I don't have the skills to DIY nor the patience to DIY or even document the process. Have fun and thanks for sharing this with all of us.

Can't wait to see it all.

One thing I would like to see with the revamped site is the ability to post larger images. This resizing all the time is killing me  :duh
Title: Re: Build Thread: Open Aire Aktiv

Hopefully the upgraded or new software will allow for larger photos

OK so no matter what I did I could not get AN to accept my photos. I resized them 3 different ways. NG. So it was easier just to post a build thread on AC. See link below.

Looks good!

AN photo gallery has been broken for years. Resizing the files won't matter. Attaching graphics files is the only way right now to post pics until repairs are affected.
Title: Re: Build Thread: Open Aire Aktiv
Post by: jimbones on June 06, 2017, 12:34:48 PM
I tried that doesn't work
Title: Re: Build Thread: Open Aire Aktiv
Post by: richidoo on June 06, 2017, 02:16:45 PM
It works if the file size is < 500kB.

So I misspoke, resizing the files does matter for posting attachments, but resizing will not help the gallery functions work. Only forum upgrade can fix that.

Updated this weekend. the fronts of the uppers are done the side panels nearly complete. shouldn't be long before I get to the finishing part. See AC for photos theres still a very restrictive limit on photo size here. Thanks.

Is that still the case with the new forum software?

I just don't have an answer yet on that. These are the issues with me not being an IT guy...

Jim,
I've been advised that we currently have a 500kb limit per photo. That can be increased, but it adds up towards the storage we pay for. If 500 kb is indeed our current limit, then what size would make it easier for you?? Any idea what the current size is of what you're trying to post? There should be simple software to alter the file size if you want to do that.

Hey Nick,

I have a variety of tools to adjust the file size. But 500 is quit small. Next time I'll pay close attention to when adjusting file size so I can make a suggestion. Thanks.

Jim,
I checked the history regarding file size. In the early days and into 2010 and 2011, the file sizes were up to 2000kb. I'm not sure when it was lowered. See if you can play with it a bit. I can increase it to 750. I'll also check regarding increasing our storage. We are not near to exceeding it, but are 2/3 of the way there. Anyone else please chime in if you wish.

Jim look at the pictures in the what are you listening to now thread, the larger ones are only 640x640 pixels. They are more than large enough and detailed enough for on screen viewing and the file sizes are around 175k. 500 k may be small if you are shooting with a high resolution camera, but we are not looking for gallery quality archival prints here,  just something we can see on a computer monitor. Whenever I shoot pics for posting here I dial back the camera's resolution setting to the lowest I can get and I have never had a problem of them looking poor online.

Try resizing them to something in the area of 640x640 and you should have no problems posting them up.

Post by: jimbones on August 16, 2017, 06:50:56 PM
Well, it's been a long road partly because of my job and partly because my cabinetmaker screwed me over. I gave him plans in first week of march and I was lucky to get the H Frames so I pulled the toppers away from him after I waited months for them and he never got started. So here I am. But I am in no rush I don't have to answer to anyone but me lol! :lol:

The H frames and amps are completely wired. I just have to install the No Rez and put fabric on the grills.
This weekend I will finish the bases for the toppers and the XO boards (WO components). I have parts for XO kitted. I'll need to order real binding posts and some hi-end wire. I am hoping to light it up in September.

lets see, 450 for cabinets, 179 per woofer, 379 per amp, lets say $150 misc. so about $2500.

   Cabinets $450 is a fair deal, thanks.

I think 450 is a steal considering its Tineo veneer.

They went live this week. Out of the gate they dont sound bad, pretty decent. I took some measurements  but I don't think it will be too long before I am able to finalize the XO. I have a dip just south of the XO point 175 (XO is @ 200 hz) and the tweeter can be about 1.5 db louder as I  may have padded it too much. The drivers are better than the Peerless/Sb29 in the Lambda. They are also more expensive.
Title: Re: Build Thread: Open Aire Aktiv
Post by: richidoo on September 01, 2017, 04:50:39 PM
Yea I use those drivers too, they are nice. I think you have the right idea going 3 way, rather than taking the SB woofer down to the bass. Obviously the servos will kick butt
Title: Re: Build Thread: Open Aire Aktiv
Post by: jimbones on October 15, 2017, 09:15:06 AM
I am now in finalizing the XO. I have all foil coils and I am using Jantzen silver caps. However, some one in another forum commented on the fact that I am using a Mundorf series resistor and a sand cast shunt resistor. Also the fact that I am using some silver coated copper wire in the XO board (short pieces 3-4 inches long) He claims it will make a big difference using better parts (Mills resistors in all areas and pure copper). Although I will make the changes, I am guessing the changes will yield minimal improvement. Your thoughts?

Title: Re: Build Thread: Open Aire Aktiv
Post by: richidoo on October 15, 2017, 10:40:40 AM
Sand cast is the lowest grade resistor. Metal oxide is better, but still not as good as high quality non inductive wirewound like mills or mundorf. Graphite is the best.

Shunt is technically not in the signal path by semantics, but it still affects the SQ. Even in shunt Mills will be audible. It's OK to skimp on midrange resistors, but don't skimp on the tweeter resistors.

Silver plated copper is fine. Insulation is more important. Teflon and polyethylene good, PVC bad.
Title: Re: Build Thread: Open Aire Aktiv
Post by: jimbones on October 15, 2017, 02:32:34 PM
I know sand cast are the worst. I was always told that if it is a shunt it doesn't matter. OK going all Mills on this.
