another great video Kevin. I just got a sub. I have it hooked up to the "B" speaker outputs so I can easily switch it in & out to compare the difference in frequency response & set the gain level .....

[@rdoc]

I got this figured out on my own a few years ago. I wish I would have found your channel back then, it took me a while to get it right. What a difference it makes to add a sub to your vintage system. I went from a good stereo sound to what seems for all the world like being at a nightclub. You get that rich floor to your sound that really gives you a live performance feeling. I love it.

[@Take_2_bible]

Can You help me please

[@lepod]

I'd never had a subwoofer, but I found my new 20 watt valve amp just didn't have enough bass so I bought a second hand Velodyne and I was blown away by how well it worked. Very useful video, thanks.

Very nice!

[@angelakozak7256]

Thanks for this video - I have run into all of the scenarios you discussed in connecting subwoofers to a variety of vintage (and not-so vintage) home and car equipment. I'm a little embarrassed to say that I never thought to check the load with an ohm meter, as you did, by splicing the wires from the subwoofer and speaker. I really enjoy your low-key and informative style - please keep 'em coming!

Thanks!

I used your solution 1. My bookshelf loudspeakers now sound more balanced being fed the full range output of the receiver. My receiver serves as a power amp for the stereo DAC, so the “point one” of the 5.1 feature of its sub out wouldn’t be missed anyway. As you showed, the hi level inputs of the subwoofer connected with the wire to the speakers worked perfectly. Thanks.

[@pedrofernandez8729]

Originally I was using my vintage receiver minus the sub, but on some songs I could "feel" something lacking in the lower range. Adding a small sub at 50hz has taken care of that.

Wonderful video. What if you're working with 4 ohm speakers and want to use the speaker inputs and outputs on the sub?

[@Nightrelic]

I never thought I would want a sub, but I won one in an auction lot and needed to test it to sell it. Most stuff I don't feel a need for it, but for bass heavy stuff like Funk and Disco, it added an extra oomph for parties I liked. I ended up keeping it. I just connected it to my B speaker jacks. It was great to find out I can just add another pair of speakers to it without a problem.

Curious, could you hook up 2 sets of speakers and 2 subs off the A & B speaker outputs? In order to have a set of speakers and a sub in two different rooms running off the one receiver.

Looks like all these connections will work, nice. The drawback might be that the sub crossover is not limiting the bass to the little main speakers? Thanks for the vid.

[@johnkuykendall467]

I bought a little line level converter from my local car audio store. The owner had never heard of using one for adding a sub to a vintage receiver. If you get one like this kicker with the attenuation pots, definitely start from the bottom and work you way up. I found on the one I bought that all the way "up" was full pass through. They ended up about 5% up from 0.

This is so informative. Thank you! Probably a dumb question but for the third solution, do I need 2 kickers for both my speakers to the sub?

[@davej3487]

Your recommendations are spot on! Wish this was common knowledge 20 years ago when I got into a PI$$ING match at the high end sales store where I was shopping for a 12" Sub with 'High Level' speaker inputs for my Kenwood Model 11. My Kenwood Model 11 was sold in the US Military Audio/Photo shops in Germany so it does not have Serise I, II or III but is 80 watts. Maybe not the best THD but works well for me. Been recap'ed 15 years ago. I knew the Sub's High Level Inputs were well over 60 ohms and basically a ghost to the receiver. But the Model 11 also has a switch to separate the Pre-Amp from the Amp but I wanted to do the High Level. The sales man kept trying to upsell me a new 2.1 amp with a sub output. He and his store did not get the sale. The store is now long gone.

[@dandiehm8414]

You sghould probably use method two , which will free up your amplifier to only play your satellites.

[@Sunrayman123]

Enjoyed those concise explanations.

[@donnystrife1908]

A lot of newer subs don't have the speaker level input. I use a similar adaptor in my system. It sounds better using the speaker out to an adaptor than a sub out. Even when using modern gear.

Hi Kevin, Thanks for making this video, After watching I stopped using the preouts on my Marantz 2275 to my 2 Infinity BU-1's & used the High level inputs instead & used the High Level outputs of the subs to my Shure SR112W's, What a audible improvement! I thought the RCA inputs were the better method to use instead of the High levels, The y adapter on the main in & pre outs was also very enlightening, Love your videos and straight forward presentation style, Nice thumbs

[@holyvanguard]

Thank you so much for this video. My sansui has a second set of pre out plugs and the u shaped plugs for the other pre out and in can I use the second preout for the sub?

[@Valleystoner]

When using the first method where you run speaker wires to the hi level input and then from the hi level output to the speakers, does it still bring the sub ohms down to 8 ohms?

I been using method 3 for a while now works great.

[@Audiorevue]

I suggestion in addition to this that I often have employed with vintage receivers in the past. is I don't know about a lot of other people but I have tended to listen to a lot of my music at a particular volume without really deviating too much from that volume. so what I've done in the past is use one of the tape outs or the tape out on any particular receiver and plug that directly into a subwoofer. now of course one of the problems with doing that is as you increase or decrease the volume the subwoofer won't scale with the volume of the amplifier but in my specific case where I don't really change the volume a whole lot the volume control on the subwoofer itself is all I needed.

[@chigozieokonkwo-eje4832]

Good day, need to ask, is it okay to connect from the high level of the amplifier directly to the RCA of the sub using RCA to bare wire connectors? This is without using a converter. Saw a couple of premium RCA to bare wire connectors and was wondering if this is what they are used for. Would really appreciate a reply on this. Thanks.

[@Poppinwheeeeellllllieeeeez]

Out to the sub and back to the amp effectively makes the sub wiring a sonic filter. If you avoid it in the chain, it is one less component to filter and / or add electronically induced noise. I run dual subs. R / L subs via a Y output per pre out to a Y and run each sub in mono off off a single output channel. Powered subs add miniscule load to the system because they are self powered.

[@grahamluscombememories9897]

When you run wires from the High Level Outputs to the speakers, is the subwoofer crossover limiting the low frequency signal to these outputs? If so, my thought is that this would be superior as the main speakers are only fed frequencies at which they can perform well.

[@guyb7005]

Thanks for this video - no one else offers info this clear! Q: I may have to go with option 1, ---- but for option 2, my int.amp (Rotel A11) only has pre-out (no Main-in) and my sub (PolkAudio PSW10) only has line in. Would I still need 'Y' cables and if so, they would go from the int.amp pre-out to ???? thanks again!

[@KaitenKenbu]

Would utilizing the high level input on the sub hooked to the amp then output from the sub to the speaker alter or colour the sound as opposed to hooking the speaker directly to the amp?

[@skylabsaudio]

Maybe? Maybe try it both ways and see what you like more? Donno honestly

[@jasonspence9516]

For the converter, I have used a Russound ADP 1.2, these are made for home Hifi, not car audio, so no extra wires! Just thought I'd share that. Russound calls it a speaker level to line level interface. Love the channel, keep the info vids coming!! (Also works for using an old, small reciever with no pre-out to connect to an amplifier via RCA or "line level"). Any thoughts on the Pioneer HPM 100's?

So when using method number 1 the crossover is actually effecting the small speakers?

This jack output is located on the rear panel next to the speakers terminals. One RCA cable to my pioneer active sub works. Output on the mono jack is always present. Nice surprise on this receiver.

[@dogratco]

An excellent bottom-dollar option: A pair of the original series of Boston Acoustics A40 (as seen in the bookshelf speakers video) going through a passive Realistic Optimus Pro SW-12 subwoofer. Replace the surrounds as needed, of course. I ran this combination for years with an NAD 3120 integrated amp, and had no need for the loudness button.

[@j.t.cooper2963]

👍🏻😎Both of my systems have amplifiers that don't cut power when both the A and B channels are selected and neither one is new enough to have subwoofer outputs. I run a pair of speakers on each channel (a pair on A and a pair on B) and a dedicated subwoofer hooked up speaker level on each channel for a total of 2 subwoofers. I think that configuration sounds the best to my ears. I had a friend tell me a long time ago that I was stupid for running it that way (speaker level Vs. low level) without hearing it first. Needless to say he doesn't come around anymore and I don't ever hear from him anymore either so it must have been a complete shock to him just how good it sounds that way. He thought the only way to hook them up was low level. I think that even if I had an amp with subwoofer outputs I would still hook it up speaker level.

[@TheAgeOfAnalog]

Thanks for that Y-connector out/in method. I never though of that. One question though, is the sub volume going to attenuate this way, in conjunction with the mains, via the receiver's volume control?

[@stevengagnon4777]

I usually use a nicer quality Y connector that is one female end to two male ends and jump the pre out to the main power amp with the two male ens and now you have a female end to use a standard interconnect to the sub. The volume will change with the volume control on the preamp just as the rest of the signal from the preamp.

[@patricknicolucci5073]

I have used passive Subs for years love the them as long as the crossover in the sub is of good quality and can produce either 120hz - 30hz or 80hz-20hz My DBX 15" bottom firing sub woofer shakes the walls with my my baby Advent II's. powered subs would be my next upgrade.

[@josephtibbs]

First, great video! I’ve always done the 1st option with main speakers in A and sub in B. As you mentioned, it’s nice to turn the sub off if you want via turning off B. But also, I have high quality speaker wire that’s thick with banana plugs at the ends, making it hard to put both into A like you were with basic speaker wire. Even with a banana plug adapter, for older receivers that aren’t set up for banana plugs (like the Pioneer in this video) it would be hard to connect the speakers and sub to A

Slightly off topic question… I have a receiver with a high level sub out, can I run a single wireset to one of the high level inputs of the active sub? Would this create any issues only having the one wire running?

In scenario 1 do you also need a second set of wires twisted together for the L channel? Or do you only need one channel going to the sub? Meaning can you just have the sub wire going to the R, and not the L with the L only going to the regular speaker. Hopefully I explained that right LOL

Please excuse if this is a dumb question.

The 8 ohms is IMPEDANCE, i.e. tit is an active or dynamic property, not just a resistive property. I'm glad this works, you helped me out, but you technically can't measure the impedance with just an ohm meter designed to measure resistance, exclusively.

Yeah I know the 2 channel tube purists are gonna spit fire at me for that. One question, how can I hook left and right signal channels through a Kicker to a single sub, or do I need to run both of my subs and 2 Kickers, as in 1 Kicker per channel? I cannot find a circuit diagram.

[@skylabsaudio]

Sorry, I wouldn't have one either. Thanks for watching!

[@robbysoaks]

Could I run stereo subs using the first method? If so, would it just be a simple matter of running a wire from the one sub's LEFT HIGH LEVEL INPUT to the left channel output on the amp (together with the left main speaker) and running a wire from the other sub's RIGHT HIGH LEVEL INPUT to the right channel output on the amp (together with the right main speaker)?

[@chinmeysway]

so to utilize low-pass filter to speakers from sub, you'd have utilize a sub's outputs. unless i am missing something...can you comment on that, thanks

[@skylabsaudio]

Depends on whether the receiver you are using has a subwoofer output. If your receiver doesnt have a dedicated subwoofer output that you can activate in a menu- then yes you need to use the subwoofers outputs or you will be sending the same low freqs to the sub and your mains. It will work, but your room is gonna have issues with phasing, standing waves and cancelling.
