Hi Dana, the RELs in this video are the old R218 and the T7i. I believe REL’s “subwoofer finder” on their website shows that the S/510 would be the best match for the KEF R7. In my opinion it is important to try to find the best match for bass “speed” between the speakers and subs. The S/510 and S/812 are both incredible subwoofers though so I’m confident that you’d be happy with either!

Hi David, Sorry I didn’t take any volume measurements when I still had the KC62☹️ It should perform well for you if you don’t have a large room or don’t listen very loud.

@@techjourney5383 I have a large-ish room but I don't really listen loud. One local dealer has a home trial service so I'd only need to pay for the courier if it doesn't suit me and I decide to return it. I'll give it a go! Many thanks, D.

Sorry but I don’t use that setup anymore and don’t recall. Also, it is very room dependent so whatever I was using likely wouldn’t work well in a different room.

I think KC62 would be perfect for a small space where you want to hear low tones without too much bass energy escaping the room. Both are really great subs but I’ve moved on to REL S510’s which give be both the speed and output down to 20hz that I was looking for.

Sorry for the delayed response. I tried both in stereo pairs and preferred the speed of the T7i’s with the LS50’s.

@@techjourney5383 thank you. As of June 2021 and the T7i line has being updated. The new new line is the TX. I'm curious to listen to the new line.

2x KC62’s probably would have been enough but I am planning to spend that $3k on something else. I will try to post a new video once I have had some time with it😊

Hi Steve, I no longer have the KC62 as I moved on to something else. Really great unit though that I know many people have been happy with. Best of luck with finding something that checks all of your boxes including the all important wife approval factor😊

Sorry for the delayed response. Out of that list, I think I would go with a pair of T7x’s as I found the prior version to be an excellent match for LS50’s. Please just keep in mind that you will likely only get usable bass down to about 30hz - maybe a little lower if you place the subs in corners like REL recommends. Hope that helps!

@@techjourney5383 Hi!! Your videos are very good! I have a question that you always use 2 subs!! How good is the pairing if I put a Rel T9i next to a Kef 92 as a second sub? Thank you

Thanks for the feedback! I have mixed subs before with good results but it is much easier to get things to sound right when they are matched subs. REL’s are designed to become an extension of your main speakers, not just make “bass”. I’d recommend giving REL a call and talking it through with them but if budget is a concern perhaps you can start with one with a plan to add another in the future when budget permits. Good luck!

@@techjourney5383 Thank you very much very good information helped me a lot!!!I will do it!! What do you think of the Kef92? I would use it for movies and music! Is it worth the price? Compared to Rel, is it a good-sounding sub? Have a nice day! Thank you

My pleasure! What speakers and amplifier are you using? Check out REL’s speaker pairing tool on their website. I found it very helpful as I was planning my journey

the $1,500 price tag doesn't really matter in your recommendation process does it?

Thanks for the comment. I think 3 or 4 KC62’s would be an interesting experiment but I can also think of other subs that I might prefer more for $4500 or $6000😊

@@techjourney5383 I was just trying, hihi :D That would be interesting to see though! ;) :D

@@yamafanboy you are correct brother, it doesn't.

Do you have any to recommend? Maybe around $1k I am missing a lot of music with my rp600m klipsch. I want a sub or pair and am seriously looking at REL T7x because of its musicality. It's a small 10x13 room and I don't want to rattle teeth in the room upstairs, I just want to fill out what's missing without needing high spl.

That’s a good way to think about it. I would rate the KF92 as being great for movies and good for music. Hope that helps!

@@techjourney5383 it does mate yeah.👍

Hi Josh, the beginning of my 2 channel “audiophile” journey started with KEF LS50’s and many different amp, preamp, dac and subwoofer combinations in two different homes and what I have come to understand for my own listening enjoyment is that LS50’s MUST be paired with just the right subwoofers for me to feel satisfied when listening to a wide range of music genres. For me, I’ve landed on a pair of REL T7i’s for my desktop setup and a pair of old infinity 8” ported subs for my bedroom setup. I’m currently evaluating other speaker and subwoofer combinations for the setup that you saw in the video, but with the various combinations that I’ve tried thus far I am even more convinced that a pair of high quality subwoofers that match the speed and scale of the main speakers need to be part of the equation in order for me to feel satisfied. Also, not only do the speakers and subs need to match each other well, but they also need to match to the room well. My LS50 setups do well in smaller rooms of my home but not as well in medium to larger rooms in my home because they don’t pressurize the room as well. Hope that helps in some way!

Thanks but I’ve already found something that I really, really like. I’ll try to post a video soon to share with the community.

@@techjourney5383 which sub did you find that you like

@@anandshah71 sorry that I haven’t posted an update video. I ended up going with dual Rel S510’s. I still plan on posting an update about them at some point.

Update video on the S510s would be appreciated

I’m assuming you are asking about the KEF KF92? Best thing I can think of to convey my feelings with these is that the dual T7i’s are more like high quality speakers that play decently low bass and the KF92 is more like a “woofer” that does what it’s designed to do in the sense that it plays low bass notes. The KF92 gives you a ton of low output and I think T7i’s augment my speakers a bit better by filling in some detail in the midrange area. I prefer one setup sometimes and the other setup other times. I think I have found something new that blends the best qualities of both and will try to post a new video once I decide. Hope that helps!

@@techjourney5383 the suspense is killing me! What was it?

🤠 I think if you listen to music with fast bass notes, like jazz or psytrance, a sealed sub would be best. But with the deep, long sustained bass notes of the genres you listed, a ported sub may actually be better suited. Most subs used in car installations are ported designs.

@@meldmagic thank u sir👌

Hi Ahad: Gold Note IS-1000.

Hi Raphael, yes I do like dual T7i’s a bit more but they don’t play quite as low as the KC62 or KF92 so there is definitely a trade off. I hear that REL is coming out with a new series soon so it will be interesting to see how they perform.

@@techjourney5383 what have you heard about future series by rel? I'm cuirius since i'm planning to purchase the S510 Thanks!

I heard that the current T series is going to either be updated or replaced sometime in April 2021. I too am interested in the s510 and planning to check one out at my dealer next week. I hear that the S510 will still be considered a higher performing sub to whatever they release next month. I’m just not sure if the S510 will be too much sub for my relatively small room.

I think dual 8” with a larger box would have been perfect for me😊

@@techjourney5383 that wud be good too :) 2 of those dual Unicore drivers wud be massive power

I have one at home on demo. It is a nice sub for the price but I’ve found something else that I like much more. Will try to post a video soon to share my thoughts.

@@techjourney5383 how dose the sb3000 micro compare with the KEF KC62?

I liked the KC62 better than the 3000 micro but it is also almost double the price. I ended up going with something that was almost double the price of the KC62 and will try to post a video soon once I gather my thoughts about it.

@@techjourney5383 in your opinion why was the kc62 better than the svs sb3000 micro?

Seemed to be “faster” and integrated better with the LS50’s. The Micro was ok for the price but I want that impressed after comparing with other subs. Just didn’t do it for me.

Looks like an interesting design and great price if it performs well!

I found something that I’ve fallen in love with. Will try to post a video soon to share with the community.

@@techjourney5383 oh nice.

you could add 4 of them, but that still wont change the fact that they are dual 6.5inch drivers.

@@parapobabam I think that if KEF had used 8" drivers instead of 6.5", it would be darned near perfect for most folks. Yes, the box would have been slightly larger, but I think it would have been worth it. As for price, they're more expensive than they should be due to the need to recoup the research costs.

The SubPac looked very interesting, a wearable subwoofer backpack that shook your body 😅 unfortunately production has been delayed for years now 🥲 I've never experienced tactile transducers bolted to the sofa but I'm sure it would help satisfy some of the 20Hz fever.. 🥑👄🥑

KF92, its a 9in in the same config

@@andriod3000 No, it is not in the same configuration. Totally different driver technology.

KF92 had blade technology!
