Q1. I want to replace the spikes, but I can’t remove them.
A1. If a spike is difficult to remove, use something to aid your grip (for example, wrapping a rubber band around the spike) to remove and replace it.
Q2. Can the rear spikes be replaced?
A2. No, the rear spikes are fixed and cannot be replaced.
Q3. Can I use store-bought spikes?
A3. No, you cannot use store-bought spikes without guaranteed performance.
Q4. I dropped a spike into the duct while replacing the spikes.
A4. Please either bring the speaker to your place of purchase or apply for repairs. For a customer to remove the spike themselves is extremely difficult.
