sub wiring question


i just bought 2 SPL Velodyne sub ,im using them for 2 chanel music , the sub has SPEAKER LEVEL INPUT and RCA LEVEL INPUT , im using A308 cr musicalfidelity power amp , my amp has rca output , so my question is which way should i connect between SPEAKER INPUT or RCA INPUT , could you guys tell me which way the best for my sub , and without
affecting the performance of the amplifier ,Any help would be amazing.

i have readed the SMS1 manual last night and i thoght it is hard to use but i try to read more and more , im using bookshelf apair Jm lab micro be , im happy with the sound but after i have readed the REL manual , they say it is better to use with SPEAKER INPUT , but mine are VOLODYNE , so any different between VOLODYNE sub and REL sub? the VOLODYNE manual does not recommend which input is better , so please advise which way the best without affecting the performance of the amplifier
Duypham,

The SMS is tricky to use - no doubt about that. Once you figure it out, it's great.

REL uses a very different approach than Velodyne. The whole "speaker level input" idea is closely associated with REL. I don't like this approach, but many others prefer it. I can give you many reasons why my preferred approach is "better", but in the end everyone must choose the approach that produces sound they like.

Chocolate ice cream or vanilla?
