Hey guys...we need a little rallying here... - Page 186

thats from the store also the same as the ones posted in the forum

The .75 cu ft flat pack is 8" deep:

Or, you could take another design, and adjust the depth while keeping the same volume.

Erich,
I just sent you a PM - Thanks in Advance!

Erich,

Could you give status on the XO for JBL 2206?

thanks

If on a budget, these should work. http://www.diysoundgroup.com/forum/index.php?PHPSESSID=a18b06385002cd9a58ad4bca473f1765&topic=107.0

Try 5ohms instead of 4 on the tweeter. Also, if needing more output, java is building surrounds right now and we discussed wall option in his thread. There may be a couple 12" options available in the higher price ranges I'm not aware of. And I plan to start investigating in wall options rigorously soon.

How about the sealed version of these? Only 6.5" deep?!?

I've got a 2206 mounted in a ~2.0 ft^3 test box with a SEOS12/DNA360. I assume I can get around to measuring it and having FRD and ZMA files posted by Thanksgiving weekend if not sooner. I'm a total hack so I won't be much help in actually modelling something in PCD.

Please speak up if anyone is willing and able to assist. I'm in the middle of repainting the interior of the house so I wasn't planning on speaker geeking for a few months.

Of course if someone is already beating on a 2206-based design I'll gladly wait and copy later.

The Waveguide/Compression Driver together are at least 6" deep, then add in the cabinet rear wall, it's not possible.

Those have a vented pole piece. I'd personally want to give it some space. Factoring in 1.5 inches for wood, and a depth of almost 4 inches, that doesn't leave much room for heat to escape.

.......And of course there's the thing Face just noted

It's from the AE web site:

http://www.aespeakers.com/phpbb2/viewtopic.php?f=3&t=2377

The 360 and the SEOS are 5.5" if I recall. That box shown was going to use the little DNA-150, which takes it down to a little over 5". It was a single baffle layer and I believe I was able to get it right around 6.5" deep.

But the CDs are closed back, so you could make a hole in the back of the box, that way the box will only need to be 5.5" deep with the 360\350. Just make a mdf(or whatever) ring or two so you can seal the box around the magnet.
Its abit fiddely with the rings and routing the cables to the CD, but it isnt impossible

What is the slimest cabinet design available without doing any modifications? Perhaps I can box out my framing to get an extra inch or two. Column depth of around 9 inches + 1-2 inches recessed into the wall...

Thanks, I was looking at the wrong place on that website.

Erich what is the largest cubic foot flatpack cabinet you plan to carry ?

I've already done the thinking on these in wall ideas. The only concern I've come across so far is:

4" deep wall, basically won't work. Will stick way out.

Vented pole, as EV pointed out. I mentioned this in Java's surround build too. It's also why I'm pushing on the alpha8a for this application.

I'm sure there are much better 8" options out there that could go in a wall, but I'm a budget builder. I'll happily do a design with any driver with adequate clearance, but the driver may need to be provided. I'm set up to do it. 3 big holes already in my wall for LCR with swappable baffles. I only sit 11' away, so I'm fine with the alpha8a. Maybe one of those octagonal 19sound drivers or something. Two side by side likely won't fit. Maybe an MTM. I can do an MTM with the alpha 8a. Just throw me any suggestions.

If someone comes up with a design using a 5 cuft box, I would look into getting them done.

But as of right now, I think even the two 15" models are under 3cuft.

Box shapes vary depending on the application.

I'm trying to get a 'slim' line made up for those that want to put them behind screens. I've got some curved ports that should be here this week along with some mid sized compression drivers.

11 is just too bulky of a column I think. I can try recessing a box in the framing, but that complicates sound proofing measures. Hrmm..

Erich,

How about flat pack kits for bass bins? For example, a 27" H, 19"W, 10"D would make a nice 3 cu. ft. sealed bin with the almost optimum 7.1 Qtc for the flattest response with the TD15M. A much smaller matching box would sit on top for the SEOS 18. Of course other kits could be offered for other mid bass drivers.

I tapered my columns to address that issue, in case you hadn't considered that as an option - they house CHT PRO-10 bookshelves (about 9.5" deep) as surrounds:

Wow, very nice!

Thanks mtg90 - pardon the temporary muslin screen held up by thumbtacks in the background - has since been replaced by a real screen, but that was the best shot I had that showed the side profile of the tapered columns. Sides covered in marine vinyl btw!

They look terrific. My problem is that I need to be at about 9-10 inches depth wise on the bottom to conceal some plumbing.

Then build a plinth to conceal the plumbing and place the tapered columns on top of it. A plinth may be dedicated to each column or be continuous, front to back, of the room...or some combination.

Depending on Fb, there might be some wrinkles in the column idea if ported.

My current boxes have internal dimensions of 34" H x 13" W x 5 1/2' D with 12" woofer.

I was aiming for Fb of 80 Hz, but no matter what I did - bigger ports (up to a 12" hole, after trying one of the other woofers as a PR), moving ports from side to bottom - I couldn't get it above 60 Hz.

All I can think is that the entire box is acting as an air column/port.

From what I gather, sealed is the only way to go for the surrounds (in the columns) when depth is a concern? Are there any existing designs around?

Waaay back it was stated that Dennis Murphy and Jeff Bagby were doing designs. Details of the Bagby designs recently started trickling out but not a peep on the Murphy stuff, and I had the impression that he was taking on the JBL-based design. Whether or not that included the 2206h, I donno. Guess we'll see in a few weeks unless EricH feels like spilling more beans. Unless, of course, someone else is working on stuff. Which I guess is what you're asking.
