Spikes for SDA. Any advice

Posts: 2,596
Attachment not found.I have not done any mods to my new SDA 's yet. I thought about replacing flat disc feet they came w with spikes. Do they really help on carpet floor and where do you SDA owners recommend getting eight of them? The feet on them now really help moving them round so if there is no difference I will just leave them on. Especially when I plan most of the mods listed in the owners manual. I have been searching for some SDA's for a year now and Karma really slapped me up side the head. The previous owner liked the bass response w his Cerwin Vegas better. I caught his CL ad the night he lowered his price in half of what he was asking the previous month . Also I did not have to drive out of my suburb in St.Paul. A gift from God for sure! As always thanks. D

Hope this helps

P.S. congrats on the SDAs. -
Congrats on awesome speakers! Spikes do help, although not as much with those speakers given the weight. The popular choice seems to be spikes from Mye Sound, but I've never used them myself. A place like Parts Express also has a lot of options, just make sure you get the right thread pattern.
Good luck! -
I use these 1.50" with Herbies sliders.If you do not plan on moving them at all forget the sliders.

Yes, big time!although not as much with those speakers given the weight.

Only issue with those is the tip is rounded off, which prevents them from piercing thru carpet.I use these 1.50" with Herbies sliders. http://www.oregondv.com/spikes.htm
Those are nice, much better than what Parts Express sells.

I have a set of the 1.5" spikes from this company. The owner hand delivered them to me as they are located in Salem. Nice guy and the spikes they make are excellent. They have absolutely no problem piercing the carpet as the tip is very very sharp. Cut my leg open, sharp. I have moved the speakers (2.3TL's) around many many times without breaking the spikes and feel they are solidly built. I recomment these spikes without hesitation.Yes, big time!

Agree with Jesse, but I haven't used the Adona spikes. They look very similar to the Brass and Granite Audio spikes.

I have to disagree Mr Z... It was a night and day difference putting spikes on, the weight means nothing...
Get some good spikes and spike them. IMO this is one of the first mods one should do even over crossover mods..
Have fun!! -
Thank you all again. I have heard of the bass brace ,but do not understand function or set up?

The bass brace is a length of all-thread that screws into the back of the speaker. There's a bolt near the top, remove it, screw in the all-thread. Lock it in place with a washer and wing nut. At the wall end it came with a bracket that you screw into the wall. Run the all-thread rod into the bracket and secure with a washer and wingnut. Do not use the bass brace and spikes together.
I used the bass brace at my old house with hardwood floors and plaster walls. My new house is carpeted hardwood floors with sheet rock walls. I use spikes here and prefer them greatly to the bass brace. I should have used spikes with floor discs at my old house. The issue I didn't like with the bass brace is the speaker can still move around to a degree, not so with spikes.
IIRC, there's some mention of Matt Polk suggesting the bass brace would be his choice, it certainly isn't mine.Political Correctness'.........defined

Just to be certain...the interconnect socket is pin/blade, correct? If so, the positive (red) binding post nuts should be on the left and the negative (black) binding post nuts should be on the right. Making this change (unless they are already correct to begin with) will result in a dramatic improvement in bass response.SDA SRS 2.3TL's

What didn't you like about the bass brace Jesse? I haven't tried it, but have thought about it.

I have used mine ever since I have hard mine, A long time ago the kids were little and I liked it for the safety factor and I heard use one or the other not both so the brace I felt was the best for safety and sound together.What didn't you like about the bass brace Jesse?

Spikes make the bigger impact in all around sound, tighter more detailed bass. The only thing I like about the bass brace is the sturdy ness it gives these speakers, it is also easier to level them vertically.

That's BS!!! Use both.. At least try it.
Spike them!!! -

I use both as well with no problems.. -
I made mine from 1/4 x 20 bolts. I cut off the heads and ground them to a point. I am guessing they do the job just as good as the insanely priced "audiophile" grade spikes.

I don't fully understand how the spikes work but I don't doubt they do. I intend to spike my stands for my 10's. I will have to put the discs under the spikes on hardwood floors. I would like to use something unique like a quarter or something instead of the plain disc if possible. Does the size of the disc make a difference in the way the spikes effect the sound?

I would never put a 100lb-200lb speaker on 1/4-20 sharpened to a point bolts. I value my investment and $100+ on spikes that look better then a bolt is cheap IMO.. Price some brass rod then learn to run a lathe then come and tell me they are insanely priced.. -
I am not cheap, just not buying the machined and polished brass is superior nonsense. They are buried in the carpet, so what does looks have to do with how they funtion? Four bolts, protruding only 1 inch on end is not going to break. They dont need to be needle sharp. The inserts would give out 1st. Oh, BTW, I know how to use a lathe too and brass is very brittle.Jeff

I used the stock steel spikes (basically the same as your bolts) provided with my SDA's before upgrading to Mye Sound brass billet spikes. I noticed a slight increase in bass response using the brass spikes. I remember reading about why brass is the preferred metal for spikes, but I don't recall where. If you're interested, I'm sure you could find it.
I'll have to disagree that brass is brittle, it's actually a fairly soft and malable metal.Political Correctness'.........defined

Unfortunately I don't think mye sound still offers 1/4-20 IIRC and 5/16 UNC are not suitable to turn down. Those are the ones I finally decided on and I missed getting my order in by a couple of weeks. I know where the last of the inventory went and have been unsuccesful in getting them out of his supply as of date...but I always hope.
Didn't have the $ when TF66 ran his. Maybe I'll try the meniscus... -
Ordered eight from Meniscus. Red positive binding post is on the left as advised. There is no hole for brace on back top of my speakers? So I guess I will have to drill my own if I want to do that mod. Seems simple and cheap enough to try out? Thanks for all the help..
