Active Monitors with Subwoofer?

post #1 of 22
Thread Starter 

Thinking of getting MicroLab Solo 7c's and saving up for a decent subwoofer.  My question is simple, how would I add a sub to these monitors when I eventually get enough money together to buy one?  Here's the back of the 7c's: http://static.scan.co.uk/images/products/super/1783768-l-b.jpg

 

Thanks, regards.

I was contemplating this at one point with my active speakers.

 

I don't think you would need to do anything to your monitors to hook up a subwoofer.  You need a separate signal to the sub at the level of your source whether it be a DAC, CD player, laptop, etc.  Try a Y-splitter audio cable to split the signal from either the left or right channel.  So the signal goes from your source to your left or right speaker and to the sub.  You may have to adjust the crossover features of your subwoofer.  If you are using two subs then split both channels.

 

I haven't tried this myself but I did ask around and this was the answer I got.  Good luck.

For active monitors, you may want to use a active sub for your system. Active subs have outputs at the back and are sort of "receivers" for the system.You will have to use balance to unbalance adapters for that option though. Or else, a RCA splitter of sorts will do the trick(or a receiver)

Yep, any good active subwoofer will have outputs on the back of it. So you connect your active monitors to the subwoofer and then adjust the crossover accordingly.

 

Its quite important to get a matching subwoofer, because even though the crossover matches their respective specifications, volume and SPL also play a factor in getting a balanced sound. Again, a fair indicator of this is the size of the subwoofer you are purchasing compared to the size of your woofer.

 

This all w.r.t your room accoustics.

What subwoofer would you recommend for these monitors then?  I'm new to this you see tongue.gif

I'm so tempted just to go down the easy route and buy the Corsair SP2500's instead of buying speakers and a separate sub.  Am I best doing this or could someone shine some light on this and explain what I should get confused_face_2.gif.  Thanks for any help.

Good point, I forgot about that.  None of my older Onkyo subs have the output option but good subs today do.

Price range?  Gallo TR-1 is supposed to be pretty amazing with all of the necessary inputs and outputs.  

NHT also makes a good line of subs http://www.nhthifi.com/Subwoofers

Erm, budget will probably be about £100-£180?  Maybe more, I'll be saving up for one if I think I need one.  I'm just worried now in case I don't get a sub that doesn't "match" from what blazer78 said, or do most subs match most speakers?

When you look at subs the descriptions or pictures will indicate "speaker in" (usually 2X inputs) and "speaker out" (1 X output).  If so then you'll be all set.

You will find lots of options in all price ranges.

I just checked the microlab speakers and its a 3-way speaker. Apparently one tweeter (1") and 2 bass/midrange drivers (6.5"). Are you finding that theres still not enough bass? Please describe your perceived deficiency if possible (e.g. does the bass not go low enough, or is there not enough oomph?)

 

The frequency response is 55Hz - 20kHz (unsure how they measured this). But is appears to be more of a hi-fi speaker as opposed to being studio monitors, in which case you probably want (within your price bracket) a subwoofer that preferably does down to 25Hz - 28Hz at least. The microlab speakers are only rated about 55W per speaker, so for better synergy you won't need too powerful of a subwoofer.

 

I have used quite a few 6.5" studio monitors (2-way, woofer + tweeter), and they have sufficient bass for me although I'm using it more for critical listening as opposed to a more relaxed lounge setup.

Thanks for the input (pun intended).  I haven't actually got the MicroLabs yet but, I just wanted to make sure that I would be able to add a sub if I felt there was a deficiency in bass.  So it's definitely possible?

 

I've currently got the Logitech z-2300's and the only thing I like about them is the "oomph" of the included sub even though it is horribly unclear as uncoordinated.  

Btw, I'm using the 7c's for my pc which I listen to music an awfully lot and game quite a bit too.  Maybe to odd movie here or there.

Yes, you can add any subwoofer to any speaker setup, unless you require lots of accuracy then you could probably go with any decent 10"+ subwoofer. Whilst it won't be a perfect balance, you will simply find yourself adjusting the volume etc. But again, I would recommend you to purchase the speakers first (if that is the pair you want). Have a listen to them and see if they need any more bass.

 

For critical listening, you might want to consider getting a pair of studio monitors (your entire budget). Then add a matching subwoofer (usually from the same brand). Studio monitors are expensive (the larger they are) but you can get away with a smaller monitor for a smaller room, and simply add a matching sub to compensate for the frequency response.

How would I connect the sub though?

 

Like this?:-

What if the sub only has speaker cable inputs and outputs as opposed to RCA?  (The monitors only have RCA inputs):-

2 ways to setup the subwoofer.

 

1. Use your soundcard outputs (if it is multichannel). Plug speakers to front channel output. Plug subwoofer to Centre/LFE channel (or plug into rear channel out if your soundcard doesnt have a subwoofer out). Use your soundcard software to configure the crossover.

 

2. Let the subwoofer manage your speakers. Plug the subwoofer into your soundcard (front channel out). Then connect your speakers to your subwoofer. Adjust the crossover on your subwoofer and speakers so they match (commonly at 80Hz).

 

With regards to your picture, well I'm not really enjoying that one. There are 2 connections to the left speaker both requiring a standard banana plug (by the looks of it) or raw wire. Unless your left speaker accepts a stereo input, I'm failing to see the logic in that. Usually one cable from your subwoofer connects to your left channel, and another cable connects to the right channel lol.

 

You will need to find a cable that connects those banana plug terminals > RCA. This type of cable is rare, you might need to visit your local audio store or check online for one. This may be an indicator of the different power output of the subwoofer compared to the speaker. So if you do choose to use such a setup, turn the volume down completely, turn on the system. Then turn up the volume as required.

 

What is your total budget for speaker + subwoofer? and will you be using these in a lounge setup? or just sitting in front of your computer (as stated in your previous post)? You may be better off with a entry-level studio monitor 2.1 setup.
