This works in practice just like a sim. You can do all kinds of frequency manipulation by tweaking the values. My sims don't tend to be very accurate... -
It's not that it can't work OK, it's just that a woofer without that spike is going to work better.
Here's a driver that I like. No spike,...Leave a comment:

The SB raw response is +14dB at 10k. Two x-over parts on the woofer isn't going to even come close to making that acceptable.
Also, your...Leave a comment:

Your assignment Grasshopper....
Load the rst in PCD, and see how flat you can make it at 82dB with 3 parts, and a 1.5k to 2k rolloff. My suspicion...

Extra x-over parts are needed to tame woofer response peaks, or breakup. Extra parts are needed for 4th order electrical filters compared to 2nd order....Leave a comment:

Not Lasse, but I don't think he's heard them with a x-over yet. I've had a pair for years. I've used them sealed (with a sub at times), and as a midrange....Leave a comment:

There is a 5dB bump in the response near 5k on my drivers that is not shown on the factory measurements. Still can work, but a notch would be needed....Leave a comment:

There's free software that mostly runs in Excel. On average, the x-overs made now are better due to the software. Not much has changed with boxes. I like...Leave a comment:

Welcome to the forum!
If you have a sub, and plan sealed box mains, the box volume is not important, as long as you don't go way small. Too...Leave a comment:

Phase can take care of itself, if you can measure, and tweak. Within reason, if you match target slopes, you can get close. This sim was done using the...

Of the drivers I've tested, the larger ones generally were lower in distortion. Peerless 6.5" HDS out perform Peerless 5.25" HDS. The 4"...Leave a comment:

I wonder if where you think it's going is the same as where I think it's going. Sure seems familiar. Either way, I have nothing more to add, so I'm out...Leave a comment:

Here's a woofer I'd probably consider for a loud 3-way. I've not heard it. I just looked at a few in the pro-audio section.

What are you trying to accomplish? I see no reason anyone would want 110dB music. Is that your goal? Is this speaker intended for use in mixing recordings,...Leave a comment:

The higher power handling is due to lower excursion at low frequencies. Lower excursion = less bass output. However, your opinion is still reasonable...Leave a comment:

I would look at the 30-40 hz range, and what the room is doing to that range. I recently reduced a box size as an experiment of sorts, to see how small...Leave a comment:

It probably is fine for what you have in mind. I read the reviews that were two or three stars. Sometimes reviews make it harder to decide on a purchase,...Leave a comment:
