Subwoofer Basics Help


I am thinking about adding a subwoofer to my system but don't fully understand how I would connect it to my Rega Osiris amp which doesn't have a second signal output other than record out. Will a sub work through the record out path? If not that only leaves me the option of using the speaker out terminals. Is there an issue running the sub off the same output as my speakers Naim NBLs? Will my NBLs be compromised? If I have to run the setup this way am I looking for a passive sub? What is the price point that gets you into a decent sub?

I own a small REL. It's ok  However, I think they are overpriced for what you get.  Also, they seem to be the only major vendor pushing the high-level connection.

I have the REGA Aethos and had the same issue.  Ended up using this volume control.

Connect from RECORED OUT to this then out to subwoofer.  Works very well to control the sound level of the sub.   Each recording has different bass content so using this small control makes it very easy to adjust bass.  Placed the control on top of my shelf within easy reach.

 

I’ve 300B SET mono blocks and run Rythmik and Rel sub pairs. Both brands are nice, but the small RELs have modest SPL with limited flexibility. REL is speaker level input; Rythmik is both. As I understand your connections, a high quality line splinter of turntable out can allow ready connection to sub and to power amp.

Give REL a call and they will walk you through specific setup based on your equipment. 

Iso-Max makes a unit (Model SP-2SX) that will take the speaker level out from the amp or speakers and convert it to a line input. Thus, being able to use any powered sub.
