Re: Dunlavy SC IVa's
Has anyone tried points or other devices under this speaker with or without success? I have recently put Walker points under my pair with a major change in the sound. Mids and highs are more airy and the bass is tighter and more buoyant. Before using these I had tried cheap points with little result.
