Speaker phase observation and question?


Hi everyone,

After months of playing around with positive phase and reverse phase connections to my Monitor Audio Silver 8 speakers, I have made a couple of observations. When connected in positive phase (red - red, black - black), the speakers put out pretty substantial bass, but the mids and treble are somewhat subdued. Upon reversing the phase, the mids and treble open up substantially, and the bass becomes somewhat subdued. To my ears, I actually prefer the reversed phased.

Moving forward to the current day, I purchased an app that tests phase using a generated tone. In testing my speakers, both bass drivers test positive phase, but the mid and treble test negative. I had read somewhere that some manufactures wire the drivers like this intentionally, but am confused as to whether or not this is the case with my speakers, or if it's a manufacturing flaw?

Any thoughts?

Thanks for the excellent and thorough explanations. I had completely missed the interrelationship between the impedance and phase angle and voltage/current interplay referenced in the posts. It all makes sense now.
Hey chewie70....late post, but I've 'been away'/out of town/preoccupied...

For eq and room correction, I run a dedicated/in line Behringer 8024 (yeah, PA stuff...but it works nicely and is reasonably 'clean') and the APO eq off Source Forge with the Peace interface on the 'puter...

One for room eq, the other for 'tweaks 'n tricks'; monitor the results with an RTA and see what's going on...

Between the 2, I could probably bend an acoustic 2x4, but that's more for grins than accuracy. *L*  I'm not so much a 'purist' of late, but having 'been there/done that/smoked the t-shirt. ;)

I just amuse myself of late...my approach to the 'hobby' isn't as 'serious' as some, but to each...*S*

Hoping to be helpful, J
@twoch is right. Especially minimalist tube preamps. A single stage, single ended gain stage always inverts.
