Adding a sub to my bookies, change my life 😃 I always thought I mainly cared about the mids, but realized that adding the lows affected scale, sound stage and perceived tonality of the mids and highs in a big way (more relaxed). In my room I prefer mains that play less low bass (B&W 805n) augmented by a sub (T/7i), to mains that plays more/lower bass. Just cleaner and better sorted. Guess this is because of the room, where the speakers are placed, where where I sit etc. For anyone interested in how bass works in rooms and placement strategies for multiple subs, audioholics has a whole KZitem series on that (just filter out the av/7.1 stuff).

Many thanks for your video. I have a reasonable setup and decided to add a sub because that is what the cool kids were doing. Having watched your video I decided to listen to my system with and without the sub connected and came to the startling decision that I never really needed one and that my system sounded great without it! It is now going into the loft tomorrow until I can be arsed to put it on EBay! Many thanks x

Agree with what you're saying however two things 1) subwoofer EQ is essential as peaks will make any subwoofer sound horrible. Cut peaks down so the actual in room response is flat or have a Harmon house curve 2) phase/time alignment. Stereo products don't have this so you'll need a avr, or a subwoofer rack mount EQ system with time align feature. 3) two subs. Multiple subs are harder to integrate, not easier. You will need to time align so each sub is time aligned to each other, look at the combine response, then align the combined subs to the speakers. Multiple subs once setup will flatten response however you likely will need EQ. If dual subs aren't time aligned then one sub could partially cancel out the other, and cancel out the speakers crossover point. You also get room gain so that will effect speaker and subwoofer actual in room response. Plus room size effects room gain, or if you've got closed or open room In a hifi you'd need to use REW and umik1 and run response graphs varying the subs phase, run about a six graphs each time changing phase on sub, then display the multiple graphs and work out which looks the best. Also by doing this you'll see actual in room response on the speakers, and the sub so you'll be able to integrate the two better. Subwoofer integration into a stereo is much harder than a AV system, as the latter have advanced feature with auto distance, and EQ. Some stereo amps do have these features but they won't be cheap. High passing bookshelf speakers in hifi is also worth doing, as the speakers won't be attempting to output full range, your amplifier isn't amplifieying frequencies the speakers can't handle, so you freeup headroom on the amplifier and speakers , decrease distortion on both, lessen port noise etc. Parasound have a pre amp with high pass. Time alignment with subs near speakers is still required, especially those with DSP, as those add delay. Simplest one box solution for dual subs would probably be antimode dual core.

Hi, this is an interesting topic and I think the concerns with subs are fair since too much base will ruin the midrange. With proper adjustment nevertheless the sub might just add a bit of drama. One thing I quite don´t understand, why would you connect the sub to speaker connectors? An active sub should be a speaker + a built in power amplifier, so that that configuration would be like coupling two power amplifier in series. I have a JL audio sub f112v2 which is connected to my preamp, but I might try the other varaint.

I fully agree with your take on CDs, and more so with remastered ones as I feel the bass suffers. However, my partner doesn't want speakers on stands so they're on wall brackets. There is an obvious lack of bass so I had no choice but to get an active sub from the same manufacturer of the speakers - Q-Acoustics. The difference is amazing and I made certain it blended in with the sound of the speakers and didn't dominate.

Interesting you speak of people's reaction to early CD. I don't think it was the CD player per se, but the recording companies rushing to get discs to market and lazily using analog masters that were biased for vinyl, so they had lift where vinyl is lossy, at the top end. When played through a medium which is completely flat, the resulting sound could be perceived as thin and sibilant, with splashy sounding cymbals and so on. "Oh no!", thinks the new CD convert. "This neutral, accurate format is exposing flaws in my system, it sounds all thin and weightless. I need more bass", Except it wasn't the system, it was a crappily produced CD.

Learnt a lot from your graphs and how to best integrate the REL T9x that the kind folks at Richer Sounds in Southampton let me demo at home for a few weeks. I’ve tried a few locations in our living room and found close to the left of the right speaker has yielded best results. Still more testing to do, but we’re loving the subtle improvements it’s made to our stereo setup. Agree that it does take a great deal of attention and testing to ensure you get the perfect integration correct. I’m now wondering if I should consider two T5x’s instead of the single T9x??? Mmmmm

I have a pair of RELs connected in mono configuration and I would never go back to just the speakers alone. The difference is well worth the extra investment as I've tried much more expensive speakers instead of the RELS. But no matter what I tried it never sounded as good as with the RELs, hence I held onto my Rega RS10 floorstanders and the RELs.

Hmmmm I'm originally anti sub, I'm a vintage man,quad amps and kef 105 speakers, a fairly good combo, ok some would argue the quad amps don't go low? Butte 105's certainly make up for it?! Just listening to some Fleetwood mac.... the recording engineer certainly didn't care about bass! I shame because John was a great player! Some tracks by them are fine, but other need some reinforcement after months of playing just can't get fm sounding right, a remote controlled sub would work great! I do have a rel, that I mainly use for cinema, but it's also connected to my mains, gain normally low on that input, but gets turned up for fm! So not boredom, far from it, never get bored of the classic sound I have, but sometimes needs a little help!

I am using two REL T5 (one a T5 and one a T5i) with Magnepan LRS in a big room alcove. I placed them directly behind the LRS and the subs are about 2 ft off the wall and the LRS closer to 4 ft. Anyway with my Nak ZX9 or Rega Planet 2000 along with Bryston it all works well. With a Rega TT it is horrendous the downfire shakes the wood floor which excites the cartridge and if you turn it up not good at all as in the subs could explode. I should point out that I was trying to integrate a Bryston phono preamp connected to their MPS power supply along with their preamp BP26 into separate connections with two cables and it flat didn't work. The hum was horrendous. I also tried the Rega planar 3 with bias 2 and the Rega mini phono and while nowhere near as much hum it still didn't work well with volume and the floor shaking. The Rel downfire is a plus usually but in the situation of turntable became a negative. It sounds lovely with the Nak ZX9 and FM as well.

I would never connect an active subwoofer to an amplifier unless there is a dedicated output socket provided for it on the amp. In my experience, it is usually the case that when someone thinks they need more bass from their system, what they really need is bigger speakers to replace their speakers that have a limited bass range. For the sake of good coherence, timing, imaging across the frequency range and having balanced, tight, well defined bass, people who are fans of good quality stereo but not subwoofer enthusiasts, would be better off investing in larger speakers with a fuller range.

Such knowledge and so little views. It's a shame a lot of rubbish gets attention on the internet and great informative videos like this hardly get any views. I want to add a an Active Sub to a 2.1 stereo amp which has 50w +50w for speakers and 100w for Sub. I have two bookshelf speakers and 1 active sub. The active sub has rca out which I will be plugging into the amp for the audio signal. So the 1 channel 100w from the amp is useless for me. Is this the right way to do this ? Kindly advice. p.s. : Kinda entry level HIFi DIY :) Bookshelf speakers : 43w max, 6 Ω (Kenwood bass reflex) Subwoofer : 70w RMS with low pass filter, 38Hz~200Hz (Edifier T5) Stereo Amp : Class d amp with TPA 3116 d2 chip with filter

My experience says otherwise. My mate who has a decent system, went on about changing turn table, cartridge and how cd’s always sounded subpar for years. He then got a Rel T/5i and promptly stopped thinking about upgrading. Now all he ever talks about is the latest things he’s enjoyed listening to. My other mate has a more high end Naim system with PMC floors stander, but real life circumstances has him sitting in a non ideal position, where there is a lack of bass. Enter a single T/7i placed carefully and he is now laughing all the way to the bank. For me, dual subs really help balance the frequency response and makes the system easier to listen to, while still allowing it to be very detailed. This is not about more bass, but how the mids and high are perceived with sub. It also adds a scale to the sound stage that I would not be without. I do listen low, why it might be extra helpful for me (fletcher Munson etc.). The funny thing is that I dislike “bass” enough that I’m partial to turning the subs down a click of two for movies. As always YMMW 🥳

I believe you can opt out of connecting either the yellow or red lead or you can twist them together. Do check Rels site/KZitem videos for details. If you make this type of connection (off a mono block or a speakers terminals) make sure you use dual subs! Like an idiot I ran a single Rel from the binding posts of one my speakers and for ages I thought the was something with my room, speakers or amp that caused the center image to be compromised. Guess what it was 🤣
