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

@tweak1 and @phusis both bring up very good points.  Yes, with infinite time, money and the forbearance of our loved one's integrating subs is possible.  For some it's mythical, and for some a no brainer to add.

I actually am sad more listeners who go through the trouble to buy subs don't love them, but it's a risky business and if you are not well versed in the use of equalizers and speaker matching you may be overcome by the expense, complexity or technology before your Valhalla is prepared. 

A quick update on my experience with SVS Micro 300 and Harbeth m30.1.

A beautiful pairing. Like they’re made for each other. The sub simply fills in the bottom range of most music. The SVS phone app makes all the difference; I would not consider a sub without a remote app now. I find myself changing volume by recording; the sub extends the range if there’s anything "down there". Could be subtle or dramatic - my choice based upon recording. But the extension is always appreciated. Makes the Harbeths into a full range setup. The app gives me almost real time control of volume, low pass filter, and other settings.

The sub itself seems fast and I notice no timing issues. Integration was not brain surgery either. Just not hard with the app and some basic knowledge.

If you’re on the fence, just do it. My guess is you’ll be very happy.

Agree on that. Do the same. Run front speakers (Salon 2’s) full range and adding a velo 15 dd+ to that. The velo goes a little deeper and gives more distortion free spl at lower freq. Gives the opportunity to easily adjust the support from the sub to the recording (or movie). Some recordings need and some music can take more bass. The best of two worlds and not so much talked about. All speakers eq’ed to the room with a combination of Dirac and Roon.

after i sold my horse and buggy, i set eyes on delivering meself from the tryranny of a DBA... als, i am still hostage ... yet we sleep, we dream of bass ...

Steveashe, good to know the M30.1 has worked out for you. The 30.1 certainly does not go too deep in the bass, reaching down to 50 Hz on paper which in my book is inadequate. Although my current Marten Dukes go down to 38 Hz, I still added a sub to the speakers. I am happy to report that the integration of the sub in my system is quite seamless as well.

I attribute the successful implementation to 2 main factors - positioning of the sub which is of utmost importance, and secondly, isolating the sub with proper isolation product. Placing the sub on spikes or directly on the floor without spikes is a rather serious compromise as I have just found.
