Speaker spike feet?


I recently acquired a nice older hifi system with Aerial Acoustics 7B tower speakers.I am not an audiophile. The speakers have heavy iron bases on them but there are no feet of any sort on these bases. I emailed the owner/designer at Aerial and he sent me a schematic of the bases which show that they originally had spike feet. He said he could provide the spikes at minimal cost. I was afraid to ask what minimal meant since I seem to remember that these bases cost $400 when new. (I'm still getting accustomed to what things cost in the audiophile world.)

I am wondering if I really need the spikes. These speakers sit on a carpeted floor with hardwood on typical joist construction floor. They sound quite good to me but if spikes would help in any way and I can get them cheap then I will do so.

I'll ask Aerial how much theirs cost but I'm pretty sure that stainless steel tripod (for photography) spikes will fit the 3/8-16 threads in these bases. The cost would be about $40 for those. Maybe the actual Aerial ones wouldn't cost any more but they are longer and look very sharp which makes me wonder about floor/carpet damage since these speakers weigh around 110 pounds each.

Spikes must pierce the carpet. Position without the spikes and then set once satisfied with location.

Spike geometry, as long as they are sufficiently robust for 100lb speakers, is largely marketing hype / bias confirmation.

Be aware that very sharp spikes will 'eat' into all but the most robust flooring.

Any discontinuity in the flooring such as warp, knots, heart vs sap wood, etc. can cause imbalance. Therefore, adjustment capability is a necessity.


The OEM spikes from Aerial Acoustics are $100. I think I will pass on those and try one of the alternatives you guys have suggested.
WTF HAPPENED. I just spent 30 minutes writting a post and it vanished before I was done. I'll make this fast. Bought a pair of Bryston A2's. Have them in my basement cave and kept the rubber feet on. I just put the spikes that came with them and WOW, a huge improvement. I have an indoor/outdoor carpeting over concrete, what a change in sound. I have learned so much from you all in the last year. My first system was purchased in 1974. Bought a pair of Infinity Kappa 8's 20 years ago. Recently took my 1974 Thorens TD 160 in for a $300.00 facelift. Salvaged about 75 of my 300 albums. Had a Adcom 555 II amp I had to buy to replace my old Pioneer 939 for more power. Since then replaced that along with my preamp, 25 year old Technics CD player. Bought a Isotek to fix the lousy electrical service here in Wisconsin. New $100.00 power cords and don't laugh, when I hooked up the new speakers I realized that I followed the instructions in the Infinity Manuel and used electrical lamp cord. As I'm financially handicapped I believe I have one great system. The new speaker Audioquest wire even has an arrow to indicate the flow of direction. Thank you all again, and please don't look down on me as not being in the same class. My circle of friends say the new system sounds great but what do they know as sound from a sea shell is good enough for them. And I would like to thank the member from Milwaukee that was helping me out months ago but when I took him up on his offer to come listen to his $50,000 system I never heard back. I understand, you don't know me, why invite a stranger into your house and risk a low life ripping you off. Thanks again you all. We all had to start somewhere, my start was in the 60's with a 3" square battery powered A M radio. I believe FM was just a dream. A shout out to WZMF radio here in Milwaukee, they were one of the first FM stations and broadcasted from a house in Menomonie Falls and played so much of the overseas Prog before it was even called that.
