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.

I have to agree the woofers in my beethovens are claimed 7” but are more like 5” and they’re tuned to play bass, limited spl for sure but clean and solid.
Right out of the box and into the cabinet these Purfi drivers are clearly better than my very nice Seas..sound as if I installed 
a highly articulate 10..As I type it opens up.. fun to hear and watch.. Dave G installed his today in his Merlins and has several hours on those. Maybe we will hear from him..These maybe the new king. Tom

Just wanted to mention, I've taken a quick peek at the SS Ellipticor measurements on the same sight and the IM distortion is almost as good as the Purifi. :) 

A shootout of these high end mid-woofers would be fascinating.
The Purifi drivers with their unique surround will reduce a polarity of shear so it does  not return back down the cone and become a part of the next impulse. Tom
I don't usually draw conclusions before 100 hrs. of break-in, but at 3 hrs. there is not a single area in which the Purifi 6.5" mid/woofer doesn't surpass the stock doped Scanspeak 8545 in a Merlin VSM.
