Not relevant. He says he will be using them with a Fender Rhodes at home, moderate SPL. You even posted in the thread before?

For home use at moderate SPL, a pair of the above mentioned home audio speakers will easily outperform the Peaveys, without breaking a sweat or risk over excursion - foam or not.

I disagree. With the typically low sensitivity of a foam surround home audio speaker (in the high 80's), and the limited mid response, it's unlikely to be any better solution than the original Peavey driver.

A Rhodes requires speakers with pretty substantial low end response unless you prefer the low end distortion of say a twin (which was commonly used). The stock 15" cabinet was barely adequate at higher volumes either. I used to play a Rhodes, so I'm pretty familiar with the challenges.

Also, Alexander, your disrespectful comment directed at me was not appreciated. Why do you think it was ok to say this to me?

I agree. I have large, heavy home stereo speakers with 2 x10's, 1" MDF, and I wouldn't consider playing the on a full range bass amp, not even HPF'd. I did play them a few times as the top of a biamp channel, but that was crossed way above the woofers range, like 2K and low volume.

My post was intended to HELP the OP, be it a man or woman. I therefor at least read the information presented before I type a reply.
What is the point in posting, if you do not bother to read through the question before you jump in with "helpful" answers.
Hence my question to agedhorse. What value can otherwise be found in a reply not relevant to the original question and facts?

Perhaps it's you who doesn't understand. @agedhorse is a well respected and part of the group of professional contributors who is kind enough to share his extensive knowledge of electronics as he does it for a living. Please think twice before posting what could be construed as an offensive post.

As for the OP, I recommend-- leave the cab alone. You are using it for something it wasn't designed to do. If you're playing louder than the cab is capable of supporting, sell it to someone who can use it for what it was intended for. The amount of money and effort you are taking on this project could easily get you a fEarful or fEarless cab in various size configurations. Or any other bass or pa cab that is of higher power and capability.

I hate to see perfectly useful equipment torn apart to be repurposed and the end result is almost never as good as the initial product it replaced.

Wow, this thread took a turn.

Anyway, after thinking about things, I think I'll just keep the other Peavey cabs I have currently hooked up to the Rhodes as permanent, because they sound better then the Scorpion loaded Peaveys. They seem to handle the lows better, and sound fine overall. The Scorpions I'll use to either replace the drivers in a Fender combo I have, or build an extension cabinet. For guitar, an open back cab should be fine. The horns and crossovers I'll probably put aside, and if I come across a suitable woofer, I'll build a couple of cabs for them.

Thanks to all for all the input and suggestions!
