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

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.

PS - I heard Debussy's La Mer, LA Philharmonic last night.  Simply an outstanding presentation with deep (for non-Organ) bass notes throughout.  Outstanding.

I also heard tracks from the Hsu/Boston Audio Society that had deep organ notes.  I could see the woofers moving, but to be honest, they were pushing rope!

So, for sure, there are limits to the performance of a 6.5" mid-woofer, but as a lifestyle choice this is an outstanding setup for a small simple system.

PPS - I'm waiting on a rack from Butcher Block Acoustics and after that I am planning on adding a subwoofer, stand by for that post! :)

My Revel F52`s have three 6.5" woofers per side. Currently using a Revel Ultima Sub 15 and two HSU ULS-15 MK2`s all are sealed subs.

The F52`s are run full range and the quick 6.5`s seem to work well with the subs.

I`m happy that they sound as good as they do !

Just added a new image, from another Audiogoner, @dmilev73 to the original posting. What’s interesting is his own speakers are rated to 40 Hz yet easily get to 20 Hz in room. Very similar experience to my own.

It validates my thesis. We shouldn’t rely on these speaker specs to tell us much about what happens when the speakers actually get into a room. The armchair audiophiles who have never measured anything have to reevaluate what they think they know.

I’m sure the DBA crowd will get all frothy over this, but nothing I can do about that.
