Large Advent Stacking Adapters ( Hand Made Solid Black Walnut With Badges )
" Speakers not included"  Sold as a pair of 2 adapters 
This was an idea from my custom cabinet maker. I have been stacking Large Advents for more years than I want to admit, ( Well over 40 years). Occasionally my systems have had small risers at a slight angle for my bottom Advents.
I have always removed the risers before stacking, being concerned about the top pair sliding off. Also, I have also used a  buffer of some sort between the 2 pairs, to protect the cabinets and prevent them from vibrating off. Now these Large Advent stacking adapters are recessed on both ends to secure the speakers and have soft pads on both sides to protect the speakers. They also come with brand new Advent Badges, complete with 2 sided tape to dress up and label your new adapters. I left them off so you could place them where you would like, left, right, middle etc. These will fit all the Large Advent cabinets with ease and still be very secure!
They are not only beautiful, but very practical as well. I know there are a lot of people out there stacking Large Advents and thought that I would share this concept with them. Please look at all the pictures they are brand new and very nicely made from solid black walnut. Please note that these are all natural without any finish applied, but a very light coating of oil is applied from my cabinet maker. This is to keep the natural wood from drying out or getting chalky. They may also have different shades of the natural wood grain and on occasion a natural knot. 
I still believe that the Large Advents are dollar for dollar the best value in a vintage loud speaker. I have cut and pasted another opinion about the reputation and sound quality of these. Double them up, add power and the magic begins! I always have a set doubled up in my studio and enjoy shocking the audiophile snobs and non-believers. I would have to say that Chasrock Services has sold more Large Advents on eBay than any other user. It is because I really believe in their sound quality and great value. They were also my first pair of " HI-Fi " speakers in the 70's and I still enjoy listening to them. I have cut and pasted another review that shares my same thoughts and opinion.
"The original Large Advent speaker is one of the worlds best sellers and a true value in the audiophile arena. These are the original Large Advents that became so famous. Even today it's still considered one of the best sounding speakers ever made. The designer, Henry Kloss, had a knack in designing speakers (called voicing) with great sound and his home run was confirmed by the entire audio world. Even Stereophile payed homage to the Large Advent as it was listed in their top 100 products in the last 40 years article. The Absolute Sound magazine further disrupted high end audio when they published an article about Double Stacking Advents that beat out the sound of several high end speakers costing 10 times as much! What fun audio was back in those golden years."
Chasrock Services is proud to be:
( ISTA 6-FEDEX_A Protocol Certified )
This is a registered certification in electronic packaging.
We are approved to safely ship any electronics up to and including 150 lb. packages.
The ISTA 6-FEDEX A Protocol is an earned certification.
This is achieved by packaging and shipping electronics to the FedEx packaging laboratory, in Collierville, Tennessee
They put that package through rigorous testing including the following:
Shock Test: (10 random drops from 30 Inches)
Compression Test: The package is then tested in a press at 976.94 lbs. of pressure.
Vibration Test: The package is then put on a vibration table and violently shaken for 45 minutes.
You must pass all three tests without any damage, cosmetically or functionality.
 These will be double boxed, surrounded in foam to insure safe undamaged delivery to your home or business. Yes, the shipping cost is a little high, but electronics are fragile and do require a lot of packaging and time to get them done right. I think it's worth a few extra bucks, because they can't be replaced. A note for you eBay global customers: ( I will get it to your door safely and insured.)
P.S. My posted shipping price is always the total!
I pride myself on extreme over protective packaging. (Please see my feedback!) I will only ship to the 48 contiguous states and I encourage eBay global shipping. Payment is expected in 48 hours of purchase and on the same token they will ship on the next business day. If you need more time, just send a message and we will work something out.
