User feedback on subs


While it’s not a path I want to go down, it turns out I need some subs for my cabin system. After trying lots of positions with little success, and after having discussions with people who’s experience and knowledge I respect, I’ve concluded it’s the only way for me to deal with some serious modes in an odd shaped room and to produce adequate bass in the large volume. Sigh.

Subs are relatively unfamiliar territory for me. Based on the conversations noted, I am leaning toward sealed subs - no ports/passive radiators -  to better blend with my main speakers. 

While I’m leaning toward REL #31s, also under consideration are Sonus Faber Gravis VI, Perlisten D series, and Martin Logan Balanced Force (now Depth?). All are subs I can get from dealers in my home state. The SF dealer also carries Paradigm but he hasn’t suggested any of those models - even their reference ones. While available at the same dealer who can provide Perlisten, I’ve ruled out JL Audio for reasons I’d rather not discuss here.

The SF have a high level connection very similar to REL - intuitively my preferred connection. SF and Perlisten (I’m unsure about ML) have an app which assists in setup though I’ve been reviewing enough setup routines that I “think” I’ll get better results with a manual process. 

The Perlistens are completely unfamiliar though appear well designed and solidly built. However, they do not have a high level connection which means I’d have to send my preamp feed to them and output from there to the amps. I have what I think is a very nice sounding preamp and I do not want to harm that purity. Perhaps my worry is misplaced. I have the same concern with the ML. 

All the subs under consideration can do what I need. But they are obviously not all equal. The REL is the easy (safe?) choice, though significantly more expensive than the others. The Gravis can be ordered to match the finish on my main speakers - not important, but nice to have. 

So - given the above, any user feedback on the subs I’m considering?  I welcome pros and cons.

Importantly, auditioning them in system is not possible as that location is a 4 hour drive each way from any of the dealers. So, I want to get it right.

Hi @tomic601 

Yeah - the room is the problem and it’s very problematic below 60 hz. Above that - it’s wonderful. The mains are Sonus Faber Il Cremonese. They’re not typically bass shy, but they’re not working here. I did try a smaller sub I had laying around (REL S/3) as a proof of concept. While it can’t go lo enough and isn’t powerful enough for the space, it did show me this is the path. 

I hadn’t even thought of the preamp driving both. While it seems likely up to the task, yet another variable to now consider. 

Thanks for the well wishes. I hope it didn’t seem as complaining about being able to listen to good music in the peace and quiet of the woods. 

Best,

Just wanted to make sure you were not looking for slam which generally lives above 80 hz. Bravo on the trial run. I’ve been blessed in my career to develop and build amazingly effective widgets based on subscale demonstration articles.

you probably do need big iron drivers and amplifiers vs a higher tech EQ sub w higher distortion. Knowing your max SPL requirements would be helpful.

They truly are first world problems. We are both fortunate indeed. 

My listening is primarily classical and jazz though Pink Floyd and Fleetwood Mac find their way into my rotation. I rarely listen much above 80 db but dynamic peaks in a symphony certainly scale well past that. It’s not slam, but full range support I’m looking for.

Given the volume of the room, (23’x32’x15’ vaulted ceiling), it seems smaller subs w/ passive radiators are unlikely to cut it.  At least that’s been suggested to me. And, if I’m going this route, it’d certainly be nice to actually get full output down to 20 and most of the ported subs roll off above that point. Hence, the larger sealed units I’m considering. I’d prefer to get the bigger REL #32s but fear I would struggle to get them up the somewhat narrow stairwell - even with the required help.

Best, 

 

there is an argument for subs made by a company that only makes subs. REL is a safe choice but also one of the best. I can also suggest the KEF kc62.
