Why I'm not adding a sub to my 2-way monitors for music


 

I've updated my blog post with more data, more analysis and the conclusion that in my particular case I do not need a subwoofer.  I encourage everyone who is on the fence about adding a subwoofer or not to read and comment.  I think that either way you'll be able to make more informed buying and configuration choices.

Everyone's situation is different but I hope the post helps you get to the right conclusions.

I have KEF R3 bookshelf speakers. They are substantial for bookshelf speakers. After owning them a few months I decided to add a sub. I added a KEF R400B, It definitely added another dimension to the sound. Although better, I still felt like I was missing something, so I added a second R400B. It has taken a while to get it right, but the 2 subs really complimented the R3s and allow them to do what they do best and the subs take care of the rest. I don't know about all applications, but adding subs worked for me.

Personally, I feel DSP and it's ilk "spoils the cow's milk". I would never think to alter the eq of what the producers in the studio intended. In fact, the goal for my source gear is to preserve that source as purely as possible to feed my phase and time coherent Dunlavy SM-1 monitors, which were designed to be used with a sub. An active analog crossover is key to setting up that sub properly as is room placement etc. I do like the idea of using a device like the omnimic, but only to tune the sub with analog circuits.

You never reproduce the intention unless your room and speakers match the mixing room. DSP no more spoils anything anymore than your Dunlavy speakers or listening room chair.

@pennpencil  Those symptoms are classic indicators that you have a room mode problem.  Narrow, tall peaks which certain music is hitting and preventing you from setting your subs to a more neutral position.


This is something fixable with EQ and measurement, really super easy.
