Q: What are the input connections for the Spider Cabinet?

A:  The left or right input (single cable) connection is 4 ohms, with all four (4) speakers active.  When both cables are used there will be an 8 ohm load on each side, using two (2) speakers for each side.

Q: How should the Spider head be connected to the Spider cabinet?

Spider II/III HD 75

- The HD75 is a mono head, which will have the same 75 watt/4 ohm total output when using one or two speaker cables between the head and cabinet.

Spider II/III/IV HD 150:

- The stereo outputs of the Spider 150 HD Series are rated at 8 ohms per side. You will need to connect both outputs of the head to both the Spider cabinet inputs.  Be sure to use two (2) speaker cables to connect your head to your cabinet to ensure you have the correct ohm load.  Be aware that the Spider cabinet jacks will produce a 4 ohm load (either left or right jacks) when a single cable is connected, which will damage the Spider 150 HD.

Q: Can I use other cabinets besides the Spider cabinet?

A: Yes, the Spider HD and 150 (combo) series will work with any standard stereo 4x12 cabinet with two 8 ohm loads.  Be aware that many guitar speaker cabinets will not have the flat response speakers found in Spider Cabinets, so the tone may be different than originally intended.  A 16 ohm stereo cabinet will sound about 3dB quieter than an 8 ohm cab, but would not damage the Spider HD. A 4 ohm load on the other hand, will damage the Spider HD 150.

Q: What are the speakers the Spider 4x12 cabinet?

A: The Line 6 Spider cabinet uses  four (4)  12" speakers rated at 16 ohm.  The custom Celestion speaker manufactuered specifically for Line 6, but a common replacement speaker is the Celestion 70/80 speaker.

Q: Is there a video where I can see the Spider Head and cabinet connections?
