Vienna Acoustics Bachs - a Little Help, Please

From the files of: "You Can Never Have Too Many Speakers"...

These followed me home this afternoon:

Vienna-Acoustics-Bach-1.jpg

Vienna Acoustics Bachs (the originals, not the Bach Grands) in rosewood.

I noticed when I picked them up that they had a round hole in the bottom and were threaded for spikes, which were not present. I originally assumed the hole was a down firing port and the spikes were required to get them up off the floor to allow the port to do its job.

After reading up on these speakers, I learned that the hole is the entrance to a chamber in the bottom of the speakers that is supposed to be filled with dry play sand - the same stuff I normally use for filling speaker stands. Each speaker is supposed to hold 20 pounds of sand to act as ballast and tighten up the bass. I'm missing the covers for the holes, but I'm sure I can rig something up.

Also, during my research I learned about the recommended placement for these speakers (8 - 10 feet apart, far out from the rear wall, toed in slightly and tipped back. The spikes are supposed to be used for tipping them back. Since I don't have the spikes, I just put a small small scrap piece of wood under the front of each speaker (visible in the photo) to tip them back. They are spaced 8 feet apart and 2.5 feet from the rear wall. That's about the best I can do in my small listening space, but they actually sound great. They are a warm, full sounding speaker, with amazing imaging and a surprising amount of bass given the single 7" midbass driver. It will be interesting to hear if 20 pounds of sand in the bottom of each will make an audible difference in the bass. Only one way to find out.

They may also be the least fatiguing speakers I have ever owned. I have some fairly bad tinnitus that is aggravated by overly bright speakers. I don't usually notice it while listening, but it can really kick in after a listening session and certain speakers tend to really aggravate it. These, thankfully, do not. Not in the least.

So, back to the spikes. In the photos I've seen online, they look quite tall, much taller than most spikes I've seen. Can any of you Vienna Acoustics owners let me know how tall the body of the spikes is, as well as the length of the threaded shaft? Since I don't have the originals, I'd like to get something as close as possible.

Although they look great in the photo, the sides have some pretty deep scratches in the finish. It's a very thick, hard, glossy finish, I'm guessing several coats of some type of spray on polyurethane. It's thick enough that it looks like it did a good job protecting the veneer, but they definitely need to be refinished to look their best. Normally, I do my own refinishing, but given the value of these speakers, the quality of the rosewood veneer and the type of original finish, I think I may hand the cabinets over to a professional in this case. Any recommendations for someone in the Portland, or even Seattle area that does good work at a reasonable price?

Here's a link to the thread about my Vienna Acoustics Mozarts S.A. score.
There's pics of the outrigger mounts, spikes I made.
The V.A. mounts are stupid expensive, if you can even find them, or order direct from their exclusive U.S. distributor.
Contact for service/parts etc is katherine@bluebirdmusic.com

Link to my thread. Pics of the stands on the last page.
Congrats on your VA's! They are beautiful! Take note of the matching veneer on the cabs.
Check that the woofer surrounds are secure to the cones. Two of mine had separated, one completely causing a blown woofer by the original owner.

Cheers, Glenn

Glenn,

Thanks for the reply and the links. Your Mozarts look AMAZING, and you got a MUCH better deal that I did.

The woofer cones in my Bachs are a shiny black, not clear like yours. I checked and there is no separation between the woofer cones and rubber surrounds. BTW, I also got the Maestro center channel speaker and it has two of the clear cone woofers.

Unfortunately, mine definitely need to be refinished to look their best. I have a feeling that's going to move these out of the scroe category, but still - LOOK AT THEM! You just don't see that quality of book matched rosewood veneer every day. Plus, they sound pretty darn great, too.

I'll probably order some of the spikes from OregonDV. Thinking about 1.5" for the rear spikes and 2.125" for the front. That should give me the proper rake needed for these. Thinking about some outriggers, but the ones online seem way overpriced for what they are. I may see if a friend of mine can make me some of black anodized aluminum at a more reasonable cost. I don't really need them (no pets or small kids to knock them over), but in addition to the added stability, I think they look kind of cool.

The cab build quality is top notch! There’s pics of the factory showing some models being built on their site I believe. You’re lucky you have the center channel.
The out riggers give me peace of mind. We’re empty nesters now, have a dog, and felt they were just too narrow, so I made the out riggers for stability. Mine have been filled with the sand, so the added weight helps.
They are excellent sounding speakers and worth getting the cabs refinished.
Cheers, Glenn

I definitely will fill the bottom chambers with sand - after the cabinets are refinished. May just go with spikes, or may get some simple black anodized outriggers made locally.

I no longer do home theater. So, I have no need for the center channel speaker. I will sell it, at a fair price, to help pay for the cabinet refinishing on the Bachs. I did hook it up last night to make sure all the drivers are working correctly. They are, and it sounds great. The finish on it isn't perfect, but perfectly presentable. It would be hard to find a better sounding, better looking center channel speaker.
 
@MCM_Fan
I am in the same boat :)

what spikes did you get and from where? And also the sand filling holes, what did you close them with?

one last question, I am assuming that the sand doesn’t have a way to go in even touch the drivers/tweeters, correct?

thanks!
 
I to have the Bachs and mine didn't have the spikes but I found some on Amazon for a good price they stick on and work great and the sand does work great
