The Stillpoints Ultra Base is designed to offer additional stability to the Ultra SS when used on a carpeted floor under loudspeakers. It also enables height adjustment when used with Ultra 2,  Ultra 5 and Ultra 6.

You get a 1/4 inch thread stud supplied with each Ultra Base.

The bases are very versatile and effective when used with Ultra 5’s under loudspeakers – they offer stability and most importantly they give you height adjustment, so if you need to raise your speakers up either at the front or back to maximise positioning you can.
