Altec A7 Cabinets | eBay
From the paint overspray they had Multicells on them so probably were used as A5's
Mine...$162.50. I guess I won't be building a pair after all. Lot's of sanding and painting though.
Nice score, I like those A6 cabinets he has
I'll be putting my Heathkit 416As and 811/802Gs in there.Quote:

I see the 3156 drivers are rated to 50Hz. I'm guessing they would not make good subs? If I can pick them up cheap I might get them. I just sold my '93 Fender Pro Tube Super Amp so I have some PayPal $$$ to burn.
This looks good voice of the theater speakersQuote:

Now that I have my shop set up in the garage I'll be spending quite a bit of time out there and need music.Quote:

That might work really well. For one thing, the sensitivity of the LF and HF sections will be so close that you should be able to delete any type of pad from the HF circuit of the XO. Bonus points if you can cross them above 800.Quote:

For the house system I will be using a Behringer 2496 active XO and bi-amping once I get my 300B monoblocks built. That will free up the 800Hz XOs in the Heathkits if the ones in the 8256 cabs aren't up to snuff.Quote:

Insulate some of the stud bays approximately where the first reflection from the horns would hit and in the corners behind the speakers, a throw rug in front of each cabinet, and maybe a couple mover's blankets that can easily be hung and removed from the inside of the garage door. You might be surprised how little treatment is needed to greatly improve that space.
Folks need to get more excited abut room treatment, the room has the most influence on the sound of a system second only to the components of the system itself.
Agreed. I can't believe the difference in my LR since I put up curtains. As soon as I get done spending my weekends picking up new Altec components I'm going to build some absorption panels. My UltraTouch denim insulation has arrived.Quote:

It's the 288-K that has ferrite magnets as well. So what's the difference between 288-Ls and 288-Ks?
I'm still learning this large format stuff. Near as i can tell the differences are as follows:Quote:

288K = 1.4 inch 3 bolt pattern mounting only
288L = 2 inch 4 bolt pattern as well as 1.4 inch 3 bolt pattern, also appears to handle more power(i have doubts since they both use the same phragm).
They do look monsterous. I might just get 'em.
Amen to thatQuote:

They originally came out of an AT&T auditorium that's was about 2 miles from where I work. I think that's too much of a coincidence for me to pass up. He's had them for 20+ years and they work perfectly. I figure the bass bins are worth $250 easy and the horns can go for $150 if I decide to sell. He's willing to move a little on the $800 so I figure I'll own the 288-8Ls for $350. Good deal. Thanks for the tip dbale!
Your welcome.
Hope this works out.
So, leg one of today's journey is complete. Amazing what you can fit in the back of a Honda Element. I might keep them as my new car stereo speakers.

They came with a bonus. The guy had the 515Bs that came from these cabs. One might need a recone, we'll see. $162 for the cabs, $400 for the 515Bs.

Great finds Alancohen you are going to have some fun... theres a pair of A7' cabs on MPLS craigslist for 185.00. I am thinking of grabbing them... but they are a little beat up
I already am. I've been housecleaning to Lowell George all morning. I never knew dusting could be so much fun!Quote:

And the 288s are spectacular. It's not that they are better...or more...the sound stage is just bigger, a lot bigger. The Mantarays seem a bit less directional that the 811s as well.
Now I have to try and fit the Heathkits in the bedroom.
I'm going to assume you are single.
I like the later Altec stuff. Would love to have some of those to play with. The cool thing about the later stuff is that the old school guys wouldn't hardly consider it. look at what you got for $800.
I basically hate you.................
BTW, anyone have any details on this N1285-8B crossover that's on the 8256s. I've searched and come up blank. I see lots of links to an altecpro.com site, but my page always comes up blank whenever I try any of them.

Single indeed. (And I got 'em for $750, but who's counting ;).) I'm so single I could stack the A6s on top of the 828s. :pQuote:

Actually a pretty neat x-over for experimenting with the 3 popular frequencies.
Ah-ha...thanks again!Quote:

I spoke with that guy a few months ago. He has(d) a bunch of other stuff as well. At the time he was much less motivated than he appears now. That's a lot of sound for the $$$. Make a heck of a 5:1 system if you have the real estate! Practically Sensurround!Quote:

I think I need to do something to protect the speakers on the A6s. I was thinking about grilles like this:
Dayton Audio HDSG-15 Heavy Duty 15" Speaker Grill 262-866
but they only seem to come in 15" and 18". The 3156 frame is 16". The gasket is pretty wide. Maybe the 15s?
They mount with this hardwear kit:
Penn-Elcom G0780KIT Large Grill Clamp Kit 260-352
It would be nice to get one that fits flush.

I have a new Border Collie in the family.
Update: So I started fooling around with the attenuator knob on the 8256s. It is quite a useful device. Having had a frame of reference of trying to get as much high end as possible, I had the knob almost all the way up, like on my Heathkits. After listening to lots of different music for the past couple of days I was feeling disappointed in the bass response. Well...that little knob took care of that. I now have the MF, HF/MF button pushed in to attenuate just the mids and have it now almost all the way down. The highs are retained and mids tempered several dB so as to let the bass really shine. It became actually too much and I turned the mids back up a tweak. It now sounds very balanced with buckets of slam and no shortage of those wonderful Altec mids. My 15W amp is still more than enough to shake the windows. Now I have to work my way through the library again...
BTW, I spoke with Bill today and the 515Bs are soon to be off for recones.
Rambling alert~!
So...I have one 515B out for recone. The other looks good.
The question is: do I want to use the 515Bs in the 828 cabs or the 416As from the Heathkits? If I use the 515s I can restore the Heathkits to their original configuration buy putting the 806As back. At that point I can use them or sell them to help fund a more compact 604 based package.
I would then use the 288s and MRII564s on the 828s until I build/buy some 805Bs. The MRII564s sound very good, BTW. Very un-beamy.
I could then put the 8256 cabs in the garage with the 802Gs (from the Heathkits) and a pair of cheap 511Bs and still use the N1285 XO set to 500Hz.
Current inventory:
LF - (2) 515Bs, (2) 416As, (4)3156s
HF - (2) 806As, (2) 802Gs, (2) 288-8Ls,
Horns - (2) 811s, (2) MR II 564s,
cabs - 2 each: Heathkit AS101s, Altec 8256s and 828s.
