Altec LF Enclosure Plans on Pdf.

I have some pdf.scans I made on Acrobat.They are of excellent quality.Here are the covers of the books the .pdf 's were too large too post on the forum if anyone is building anything and needs a set let me know and will send to you.The first cover shows plans that are included the second(More) are of the 8000 series.Todd's putting together a library at GPA but in case there is something that is not available I may have something got quite a bit of Literature.Just click on the pics to enlarge. Regards :)

Great post (the one above from AB)

What is the best size cabinet for my 416B LF driver. I understand the 846 is too small and the 825/828 is too large. I just purchased a pair of 399's from GPA so HF is not a problem. I am searching for a LF box to complete my project. Horn loaded or bass reflex is what I have in mind. I just need the correct cubic foot box. Suggestions please...
Thanks

hello
I bought a folder with those drawing as well,but it?s really hard to read the measures so if you have better drawings of the 210s and the 815s I?d be most grateful

Hi Marv, the optimum cab for the 416 is 7.5 cu. ft port size 2 1/2" x 11"

Yes these are excellent to read, they are not scans from a scan they are from Altec Application notes published from Altec very legible, you don't have to squint just PM a email address and I'll attach

AB and others.
Is there an Altec box, bass reflex or horn loaded that fits this size (7.5 cubic feet)? I am really leaning toward a bass reflex box, but I am open to suggestions. I also would love to find a 1505 horn to mate with my 399's to top it off. My ultimate HiFi system...
Thanks.

Heh, problem is, you're not alone....

I see where there is a guy in Florida making wood horns.
His 1505's go for over $2800. YIKES, I don't want them that bad...:eek:

There is no single 'optimum' cab alignment, only an optimum based on the needs of the app, so for this one it's a generic 'one size fits all' with a ~42 Hz Fb best suited for old vinyl/tape playback or M.I. apps where there's EQ available to shape its response to the room somewhat.

GM

Yeah he does beautiful work. Considering all labor that goes into those, the price is not as outrageous as it seems. That's a LOT of hours of skilled labor.

Want to make a pair yourself? You can. Just follow this thread:
The construction of a multicell horn - diyAudio
YOu could even use heavy paper or card stock.

Yes GM, Just trying to get him in the ballpark or close I was basing those measurements on the model 19 cab.Once there he can always tune the box.


Pano, Yes they are quite Awesome he does beautiful work.What's even cooler he constructs them in his living room after all cuts have been made.Limit the hrs. in the cold garage/shop. ;)

I've got a line on a pair of 1505's with single throats for $1500 but he doesn't want to be bothered with the shipping and they are half way across the country damn.:khan: seems like there is alot of that going around these days. :rolleyes: or don't need the money enough.:laffingassoff:

The M19 is ~8.3535 ft^3 net and theoretically tuned a bit lower, though its generally leaky construction will raise it somewhat, especially over time if not gasketed and its hardware periodically tightened. IME though, ~7.5 ft^3 is fine if sealed as Altec recommended, but vented needs to be > 10 ft^3 for adequate tuning flexibility, so I guess we'll have to 'agree to disagree'. ;)

As Always though GM I'll defer to your opinion as I value it more than most. :2thumbsup: ;) :D

AB,
Where do you consider half way across the country? I live in Ohio, that's half way across the country, IMO. If not too far I could consider a drive to pick them up. I'm sure they would complete my system at whatever size I determine to be the optimum size.

I will need to do more research to determine that. Man, ain't this fun?

$1500 for the pair is typical form what I've seen over the years. The 500Hz horns seem to go for about $50 a cell.

I'd Looooove to have a pair of 1505s.

Thanks John,
The scans are great quality. Good to have for reference material.

Try living on the other side of the world and collecting Altec stuff.
I've encountered some complete a$#hol*s who refuse point blank to ship anywhere beyond 'the lower 48'.
Thankfully those charmers lose out now as I can buy from GPA!

Magnarc, Don't feel bad I can't get things packed and shipped a 4-500 hundred miles.

That's why I went to L.A. to pick up my 803B horns. Stopped by the seller's house and popped them in the back of the truck. =) He was willing to ship, but the cost was high.

I feel your pain about getting stuff shipped to Oz. Even living in Hawaii - a US state - it was hard to get eBay sellers to ship. Many just would not do it. Now that I am on the east coast of North America, shipping seems unbelievably fast and cheap. I love it!

I hate it too, so switched to Flickr. I used up all my allotted BW for uploading from my computer to this forum in the first few posts I did it, so is there a way around it that I missed?

So, if I wanted to build a bass reflex (vented) box for my 416 It would need to be 10 cubic feet. Am I reading you right?

Hi Marv, I think GM was saying that it could be 7.5 to 10 cu ft. for it to be optimum you really have to tune the box to your room.That's what I think he meant. ;)

Generally bigger the box the better the LF will be.

There is a discussion of box size and such for the 416 here:http://www.hostboard.com/forums/alte...omponents.html

BTW, thanks for posting the scans and offering the others, good form!

Dang,
I hope I haven't offended anyone here. I tend to do that on occasion. I am so ignorant on audio I ask questions that seem offensive.

Anyway, I really appreciate all the really knowledgeable comments that set me straight. There are so many variables when it comes to selecting the right speakers I get confused. Also, it seems everyone has their own opinion as to what is correct for a given situation. I'm not in a position to say they are right or wrong, but it can get a bit confusing for someone like me.

I hate it when good people on our forum get too personal with comments. It really does not help in solving our problems. I know this forum is open to all comments, but I know everyone will concede we seem to drift off in other directions at times. Thats OK and even fun and enlightening at times. Just as long as it doesn't get out of hand.

Anyway, I have puked out my guts enough here, so lets get back to the topic. I still need to build that project I have been dreaming about.
Dang, I need a drink...

hey ab..there is a box ive been wanting to build, cant remember the cab tho... its the trapazoidal horn came with a 3156 i think it was part of a system that had a 3154 sub box, i couldnt find the plans for either. a-9x? i think it was the guy in the netherlands who found a nice little stash of these.... was it the a7-500

Guys, let it drop! No offense was meant, even if it did seem that way. It was a misunderstanding.

Don't we have better things to discuss?

Yes - take the rock-throwing war offline.

It was a case of misunderstandings.

Altec Best:
Your inbox was full when I checked!
This may belong in a new post but this is an answer to how I would modify a 511 to an E:

Hi John, Sorry about not checking my messages...not quite settled yet....getting close though! I got my pair from eBay and I paid what every one thinks as too much! I think it was a little more than 600 dollars for the pair. But whatever, it allowed me to listen to GPA's alnico 288H drivers which are insanely good and finish the playback system.
As far as dimensions are concerned, I can certainly help.
I assume you have the expertise to weld and shape aluminum?
1)My first suggestion is to build the plates that mount a 288 driver.
2)remove the hanging rings from the 511b and clean up the surface
3)measure the line to slice the 511b horn (this is where I could help!)
4)slice the 511b
5)weld the mounting plate
6) smooth perfectly the throat from the plate going into the horn on the inside.
...for high end response you need to do the best job you can in this step
7) apply 288 and enjoy!
8) curve open cell foam on the bell lips of the 511e and hear the improvement!
I started to tackle this and never came up with a "finished" idea per se.

Best regards, Steve
