There's a lot more bass in a 6.5" driver than most of you think

One topic of discussion I often see new audiophiles touch on is whether to get larger speakers for more bass.

I usually suggest they tune the room first, then re-evaluate. This is based on listening and measurement in several apartments I’ve lived in. Bigger speakers can be nothing but trouble if the room is not ready.


In particular, I often claim that the right room treatment can make smaller speakers behave much larger. So, to back up my claims I’d like to submit to you my recent blog post here:

Look at the bass response from those little drivers! :)


I admit for a lot of listeners these speakers won’t seem as punchy as you might like, but for an apartment dweller who does 50/50 music and theater they are ideal for me. If you’d like punchy, talk to Fritz who aligns his drivers with more oomf in the bass.

No there is not. And there never will be.

There is a sense of Bass but not to real scale.

I think you missed the point of my original post, @ishkabibil :)

Schroeder’s frequency does vary from room to room. In general, the larger the room, the lower the Schroeder’s frequency and more directional bass is.

for a typical concert hall, it can be as low into the teens if not lower. So everything is directional, even double bass and the lower/lowest registers in the organ.

And I wonder if that’s why we are never able to reproduce concert hall acoustics in our relatively tiny rooms

@erik_squires apologies if you have mentioned it. back to your original post. I wonder how big is your room? 6.5" may be good enough for a medium room, but might be a bit lacking if there isn't enough travel to move enough air to energize a large room.

     The standard procedure for installing a 4-sub DBA system such as the AK Swarm, includes the final step of inverting the phase (simply by reversing the pos. and neg. connections on the sub) on each of the 4 subs sequentially to determine if any individual sub's phase inversion positively effects the overall bass performance in the room of the 4-sub DBA system as a whole.  
       In my 23'x16'x8' room, currently without any bass room treatments and without the use of any DSP or electronic room control/equalization of any type, I noticed no improvements in the overall bass performance in my room of inverting the phase on any of the 4 individual subs comprising my 4-sub AK Debra DBA system.  
      However, this does not mean that phase inversion on a particular individual sub in other 4-sub DBA systems would not be significantly improved in overall bass performance. I believe only a brief audition of a good quality 4-sub DBA system would be sufficient to convince the most ardent skeptic of this concept's near state of the art effectiveness.
      I have no stake in this concept except the $3K I spent to adopt it, my intention is solely to spread the word of how amazingly well it worked for me and will work for anyone else guaranteed, regardless of room or main speakers utilized.
