Geddes multiple subwoofer method - 3 subs vice 4
@audioquest4life wrote: I feel like the Geddes approach for sub integration closely resembles what I have been doing for years without even knowing this method. So, my 18” deep bass and 15” mid bass drivers on the field coil speakers become part...

@rauliruegas wrote: That’s why THD in the bass range is just so critical due that high THD levels as the JTR ( that are for HT not MUSIC: ) subs afects all the whole MUSIC frequency range system due that the different bass frequency ranges devel... 
How important is the efficiency of a speaker to you?

Help with XLR ICs.
I’d recommend XLR IC’s based on Mundorf’s Silver/gold solid core wires (i.e.: 99% silver + 1% gold). I use their wires as both speakers cables (1mm variant for the lower midrange on up) and XLR IC’s (0.5mm). Sonically I would describe them as the...

@atmasphere wrote ... it may interest you to know that high efficiency drivers, in particular woofers can be 10x more expensive than drivers of similar bandwidth and power handling that are not efficient. As an example the TAD 1602s (15", 97dB, ...

@atmasphere wrote: ... you’ll find, if you look, that most producers of higher efficiency speakers tend to use tube amps. Being few of these designs are vintage, or so I suspect, it hardly reflects a strict need for a particular driver-amp typ...

@atmasphere wrote: The issue is that most amps made using feedback, which includes high power solid state amps, is that the output transistors usually limit the design's Gain Bandwidth Product, resulting in a loss of feedback at high frequencies...

@invalid -- That's not to say it can't be great match sonically.

How important is the efficiency of a speaker to you?
@lonemountain -- The question is, certainly to me, what we’re actually disagreeing on here. My remarks above were aimed specifically at the parameters brought up by you, namely distortion, dynamic range and "better bass," and I’ll maintain that h...
