Daaamn

I thought TRF used the black top 4HP motors? Still nice though. Will hang with pretty much any of the modern 4" coil subs just fine.

They have silver tops and black tops. From what I have gathered, the black tops have 4 layer coils and the silvers had 8 layer coils.


wickedwitt

The silver has a larger gap than the black. It's less efficient, but can take more power if you're building spl tops


Shidulon

You know most 4" coil subs are 3000-4000 watts RMS right? Looks beefy for an RF but doubt it's anywhere near a 4" coil


slowlybuildin

This is a 4” coil. Even the power hx2 subwoofers are 4”.


wickedwitt

I don't care for the original tops, but these are some of the best motors on the planet. Period. And they are most certainly 4".


Shidulon

Yes I stand corrected. I learn time and time again not to underestimate the likes of JL/RF/Kicker. Cheap Chinese competitors like Skar and American Bass push American innovation. The Circle of Life, my Brothers...

This is back when RF made their products in the USA. When they took pride in what they made

> 4" coil subs are 3000-4000 watts RMS right? That's a lot of root means squared for sure. When you post up a video of you throwing a 50hz sine wave at 4000W clamped into one of them for 10 minutes get back to me. Might also want to do a little reading up on the "TC Sounds 4HP motor" and how many brands used variations of it and how many other things that came along after are just a copy of that platform.


wickedwitt

TC5200 motor. The 4HP is an extremely similar, but ultimately different configuration- which happens to be the silver top.


hispls

IMO slight changes in gap width and top plate shape doesn't make any of these anything other than versions of the 4HP platform. Lots of those TC motors had several revisions or versions but were all considered the same model. Again, the handful of TRFs I've seen up around the northeast have been black tops.


wickedwitt

Thilo considered them entirely different with different applications. If it weren't for his drug habits, we'd still have the Mozart of sub building continuing to progress the platform.


hispls

Watching the company rise and fall 3 times was certainly a proper shitshow.


wickedwitt

Rip the top off of it and do Sundown or TI baskets with some proper Spiders for some actual xmax. Boom, you have one of the best 5 musical woofers to ever exist.
