Subwoofer Comparison Sonus faber Gravis II and REL T/9i

Adrian unboxes the Sonus Faber Gravis II subwoofer and compares it to its competitor the REL T/9i. This is going to be Part 1 of a 2 part video, where we compare the Sonus faber Gravis II with the REL T/9i sonically and physically.

Crack the subs open, show the drivers, show the amps, show the internal build of the cabinet, listen to both and gives us your thoughts. That's te kind of review that's needed. People watching this reviews would like depth of information.

[Psyphonyx_Life]

Definitely want to stop by again for more in person listen. Thank you!

[mmdusa]

Pretty. I love my T/9i. Now I need to hear the 9/x.

[saltzine]

Helpful video. I just picked up a Q201E and am anxious to see how they do with my Olympica IIs when my room is built. Plan to probably only use the sub with streaming, otherwise just the Sonus faber for turntable listening.

Thanks for the insight to sumiko. It’s fascinating. I wonder what John hunter would would think of the copy cat sub. I like the Rel for it’s separate.1 lfe input

[alternatywnetestyinsidera]

There was no follow-up of this film I belive? The main question is HOW do they both compare? How do they sound????

[bippie]

When are going to do part 2? I would like to hear the comparison as I already have a REL sub and I like it, but I now have some Sonus Farber Speakers and need a second subwoofer and I'm not sure which one to buy!

[anaussieaudiophile]

Looks good Adrian looking forward to your thoughts in comparison. 🎧👍🙂

[egit]

Looking at these two subs. Would it be possible when you showed a deeper look at the Gravis line to show the different woods? I am trying to get a handle on Sonus Faber's Wenge usage but the website photos are not helping that much. Thanks!

[davedesmond]

Adrian...great comparison and very informative. My question is how do these subs compare with the B&W DB range? Thanks!

[markwilliford]

Please bring us the comparison video - extremely interesting background you provided on this. I am on the brink of a significant speaker upgrade (primarily because I want better bass) and sometimes wonder if serious subwoofers might be the most effective solution. I do have a PV1D paired with my B&W 804D2s, and it helps, but I am always concerned with placement, phasing, crossover settings, etc. Thus my current thought is larger full-range speakers. Anyway - a comparison and thoughts on this from Adrian and Villip would be good viewing. Keep it up guys and thank you. I truly wish your store was close enough to visit.

I love my pair of REL T/9is! They were easy to integrate. They have revolutionized my Magnepan 1.7i system. I was in bass denial for a while with the Maggies. But there is no significant sub bass and no percussive bass slam. Adding the RELs fixed all of that. I put them on hockey pucks to decouple them from my hardwood floor otherwise they shake the whole house! They are attached via Kimber Cu high level connection cables to a pair of Bryston 28B3 monoblocks.

[filipedasilva]

hi! thank you for the video. did you manage to compare sonus gravis vs rel? are they comparable audio-quality wise? thank you

[rainman]

Seem to be learning ya products on the run ...

[brentcollins]

Where are these made? Italy and China?

[Totalplonker]

If one wants a speaker, one goes to a speaker maker.
If one wants a subwoofer, one goes to a subwoofer maker.

Hence the reason why I've got sonus Faber sonetto's hooked-up to stereo Rels 🥳

[howardskeivys]

I really look forward to their audio performance comparison. My rig incorporates 2 Rel T9X subs. As you unboxed that sub I thought someone had duped you and slipped a Rel in that box.

They could almost be manufactured by a 3rd party, and packaged and marketed separately with a few minor cosmetic differences.

[damianzaninovich]

That was simple but efficient, informative on a subject I wouldn’t normally watch. Beautifully made subs. Concrete or wood floors? Without hearing either one how could you go wrong?

[Frater_Saxum]

Title should be "unboxing", not comparison. It is really dissapointing to see the complete video expecting that by some point you will start comparing their sound and performance, and that never happens.
You say there will be another video for that. Then fix the title for this video.

I like the smaller version "Gravis I"
