New MOFI speaker (Andrew Jones)

I have a pair of Emerald Physics 3.4s OB, 12" concentric woofer with 1" polyester tweeter, outboard XOs, floor standing. The line is no longer made. The 3.4s MSRP was ~ $4500, but Ive seen them go for < $1000. Highly recommended

Many here probably know I have Emerald Physics 3.4s; Open Baffle, 12" concentric with 1" polyester tweeter, outboard XOs. I was shocked when I received them as the XO/speaker jumper wire was garbage, AND, not long enough to get them off the bases, which vibrate like crazy. I immediately upgraded the jumper wire, and also would have upgraded the wires in between the speaker binding posts and the drivers, but the small channel they fit into on the back side of the baffle is not DIY friendly, although I could bypass them externally, the binding posts likely present a problem. I have seen many of the EP OB speakers for sale, alas, their supplied photos always show the XOs on the bases, and the garbage jumper wire. I send them all emails about what I did, but never got a thank you, so Im guessing they never bothered to do the simplest upgrades. BTW, the 3.4s and their similar models are terrific buys on the used market

I love my Emerald Physics 3.4s, open baffle, concentric 12" driver with 1" polyester tweeter, and outboard XOs, so I am set up for a digital amp, though currently am using Rics short-lived EVS 1200, which after a total cable upgrade sound vastly better than when I first bought it (which was still darned good), plus, I moved away from CD players used as transport: the Audiolab 6000CDT is an unbelievable bargain. EPs come up FS occasionally, and at terrific prices, way lower than the MoFis

IMHO, it's popularity comes from the concentric 12" driver. I have Emerald Physics 3.4s, floorstanders, OPEN BAFFLE, OUTBOARD XOs, 12" CONCENTRIC DRIVER WITH 1" POLYESTER TWEETER. Sadly, they are no longer in production, BUT, they come up FS occasionally at a fraction of the MSRP of these. The 2+ series additionally has 15" woofer/s

Very interesting 411 about the Qualios. I didn't see any DIY info.

I absolutely love my Emerald Physics 3.4s. I have Mark Ss personal pair, which I assume have upgraded XOs to which I upgraded the  CRAP jumper wiring, making them long enough to get the XOs off the bases, which vibrate like crazy . This simple DIY alone was/is a HUGE improvement
