Considering the RS225 for a 2-way tower

[rpb]

The sale price has peaked my interest. I'm also looking at the 8" Peerless Nomex driver. (Also on sale.) The tweeter that I want to use needs to cross at 2.5k. I have others that can cross much lower. I did a PCD sim, and it looks like the part count will be reasonable. Has anyone heard this driver in a 2-way? How low was it crossed? What can I get away with? How far down does the breakup need to be?

My plan is to use this without a sub-woofer, and powered by an old Sony HT receiver.

Here's a couple of PCD sims using the PE measurements.

I'm thinking the p (paper) cone version will have a smoother breakup than the aluminum cone version so the p may be a better fit in this application.

The 225 is one of the most benign aluminum cone woofers ever.
I have heard it be happy crossed at 2k, and your sim looks good, so I say go for it.

You can always mock up one at 2.5, and one at or just below 2, just to make sure you're happy.
Since you have options.

I put the RS225A-4 with the RS28F with a simple LR4 at roughly 1800Hz. The combo exceeded all expectations. The most surprising part was how clean the midrange remained under stress. Remarkably good woofer and an exceptional value.

I don't think that the P versions will go as deep as I'd like. These speakers will be used mostly for dvd music concerts I have on disc, or that I can stream from Netflix, and You-tube. I like to watch some action movies too, so I want as much bass extension as I can get, but without a sub. In the room I will be using these, I have limited equipment for good bass management, and I don't like the look of a sub, or the extra equipment in this room. Even these towers will be a little smaller than ideal. I have Morel tweeters that can cross at 1.5k, but I'd rather use the Peerless (H26 something), and it needs to cross higher.

If I use the H26, crossing at 2k probably is not a good idea. If the Morel fit the same cutout, it would be a bit less of a gamble.

Have a look at the Wavecor 30mm. It can cross below 2000 with ease. It's a bit spendy, but it's a very nice tweeter and robust enough to keep up with even a pair of RS225

I'm trying to work with what I have. The DMS30 Morels easily will cross at 1.8k. I've been using the H26, and like it a lot if crossed around 2.3k, or higher.

I meant with your alternate tweeters at or below 2k.

The Peerless 830869 is also on sale, for even less money.

In the box size I have in mind, the bass response of the two drivers is nearly identical.

It's the extra woodworking that would be an issue, although I could probably try both.

[davidB]

That's why I said mock up. Build a solid but(t)-ugly test box. Screw it together, don't even bother gluing it.

[rpb]

Here's a 1.8k 4th order for comparison. The breakup is pretty much the same as my filter crossing at 2.5k. That's probably low enough based on what Pete says.

Any opinions on the Peerless 830869 compared to the RS225? The Peerless is currently a lot less expensive.
