I wanted to post an update, because so often I read an older thread and never learn how it turned out. The 4-5000 upgrade speakers arrived. Apparently the hold up was the supply of metal they use for the cans. It took couple hours to get the old crossovers out, new binding posts installed, and speakers on the old Ohm Walsh 4 cabinets and ready to go. I’ve been listening and average of 3-4 hours a day for about a week.
The difference from my old 4’s is huge, and the sound is just more of everything. Gobs of base, which is still settling in. I turned of my subs. These speakers actually go lower than the REL T5’s. I have a large but narrow room with the speakers at the narrow end and pretty much in the corners, and I’ve got the base set for small room. I’ll let them continue breaking in for a while before tweaking the various adjustments or placement.
an interesting note - they sound much louder at lower dB levels on my NIOSH sound level app than the 4’s. The music is just denser, but certainly not muddy. I’ve played every War album I have twice. All that percussion, horns, and bass just gets the whole room rockin. Highs are airy and clear. The bell or whatever it is on Mars Hotel, Unbroken Chain floats around the room near the ceiling. I hear the air on every note sung or blown.
couldn’t be more impressed or pleased with the improved performance
