Phoenix Gold Phorum

Well, the local store gave me a pair of Memphis PR1 tweets and they fit in the existing PG RSD tweet mounts, so my tweeter issue is solved. I'm very pleased w/their sound. I love that I can angle them in the flush mount and I feel that has made all the difference in the world.

I've been looking for a set of mids too. One of the installers at the local store has a set of Memphis Mclass mids he'd seel me for $50 used and some visual damage but it's all on the magnet and has no effect on the sound what so ever.

I came across these.

And both installers at the store use them. But they're 8 ohm drivers. They swear by their sound and I like what I heard from them, so I'm entertaining the thought of getting them.

Would there be a considerable difference in sound from an 8 ohm driver vs the 4 ohm Memphis? I don't know what the sens of the Memphis is.

The amp will be the PG ZX450v2 So I'm hoping that the 450 will do somewhere around 75 wrms at 8 ohms. I know it'll do 111 at 4 ohms, just at 8 ohms??????

Your thoughts guys.

Well at 91dB sens, if the Mclass mid comes back (I emailed Memphis support) at 89 or less, I'm getting the Seleniums.

I still want to know your thoughts.

You should have too much problems with output @8ohms

uhhh is that a should or a shouldn't....I am particularly interested as I intend to run 2 os gs redline 15s that are each eight ohm drivers off of two m100 bridged...Problems? what is the output difference ;between 4 and 8 ohm bridge?

I've run eight ohm mids and never had issue on a bridge but never had the inclination to run 8 ohm stereo before so I don't know...never run 8 ohm subs before either though

4 to 8 ohms is a loss of half the power, or 3dB. You are running active right? Then either way you need to level match your tweeter and mid.

As Tom mentioned half the ohm = -3 dB, that's why if the Memphis is 89dB 1w/1m or less I was going to buy them. The Selenium is 91dB so I don't think that a -2dB difference would be a big deal after you factor in the Memphis at 4 ohms and the Selenium at 8 ohms.

Anyway...... I just bought 2 of them. I thought I heard that RP (the owner of the local store) stated that he believes they're 89dB.

Here's for the 450 running cooler.
