Genesis servo 12 to Infinity Renaissance 90

[Are Gjerde]

Hi

I am the proud owner of a pair Infinity Renaissance 90 which i love. But I used to pen IRS Epsilon. I regret the downgrade especially due to the difference in bass. To compliment my rens, I’ve just bought a subwoofer called Genesis servo 12 and I’m waiting for it to arrive in the post. I’ve found some, but not much info about it online. I know it was meant to be set up together with Genesis IM 5200, IM 8200 And maybe IM 8300. But most of the subs I see online has their controller/amp attached to the subwoofer, whilst the one I’m waiting for has a separate controller meant to stay with the HiFi setup. I’ve seen some similar, but with only three buttons (Seem to be lacking low-pass-knob?)whilst mine has four.

Any info or experiences with this subwoofer will be most appreciated.

I’ll try to upload a few pics of the one I’ve bought (from previous owner)

There's not really much difference between the external amp of the Genesis sub and the built-in plate amps of most conventional subwoofers. It doesn't have any high pass filters (unless they added one with the addition of the fourth control). If your existing system has a subwoofer or preamp out, use that; otherwise, just connect a pair of speaker cables in parallel to the ones already between your amp and speakers, and connect those to the sub.

The R90s already go down fairly low, so you'll probably want a low pass crossover frequency no higher than 40hz or so.

Thank you for replying. That sounds right. That’s what I’m aiming for. The fourth control is a high pass, yes. But I’m thinking of adjusting it to 22hz, which is the lowest and then adjust the low-pass to about 40, like you suggest.

Have you tried this sub yourself at any point? Impression?

No, I've never even seen one in real life. If the newer version of the amp has a high pass filter, then it might be preferable to send your preamp outputs to this amp, then send the high pass outputs back to your main amp (assuming you have those inputs/outputs).

I wish it was a high pass like that, but instead it seems to be a high-pass For the woofer. I’m not sure why one would prevent it to go down all the way...
