Yup, just like B&O used in their 3way bookshelfs.
Back to regularly scheduled program. Another fine midrange, highly recommended by John Krutke, is this tiny 4" woofer. Yes, they call it woofer. I used it in my short line array long time ago. Its still available, very cheap, yet with very low distortion. Being metal cone, it has breakups, but they are high, easy to filter out. Highly recommended mid.

I didn't plan on getting into the details of my build in this channel but one of the features I am going for is using less XO components. Second order only. I want the system to blend more.
I do understand that crossing lower to the tweeter will improve the off axis. Originally, I was going to use a 7 woofer, to a 3 mid, to a 3/4 tweeter. I couldn't find a suitable 3" mid for some of the other aspects I was going for. There is a Peerless full range 3" but its not going to become available
I need some teaching here. Why is a lower QTS driver with a larger magnet better suited to a narrow/skinny baffle?
I do plan on using these in a rather slim design so I guess that works out
If I understood correctly:
The low qts mid driver and the long stroke smaller magnet bass driver were intended to work together in a narrow baffle.
I really wanted to use the NE123W-8 but it didn't become available when it was supposed to
Interesting driver. I have two 7s going down low so I don't need the extension. I have not used any Artum Cantus drivers. They seem very expensive for what you get. Maybe they have some special sauce I am unaware of. Sort of the like the Wavecor which seem ordinary until you look at the Q specs and find out they are very special.
The GRS 8" Mid planar. Probably the best $65 I have ever spent on HIFI.
Keep in mind while looking at these graphs, that the measurements were taken after an entire winter of screwing around with horns and waveguides. Its not like this if you just screw it to a baffle naked. But its also not super far off
Interesting. I once bought the 2.5 or 3" version of this to use a filler in a limited XO 3 way build. It really sucked. Like really really really sucked. Kind of put me off the whole Dayton woofer line to be honest. Must be like anything else, there are gems and there are turds within any lineup
I use them with Vifa NE225W-08 and Fountek NEO CD3.0. Excellent mid drivers and not expensive. They are almost a full range, and 3.5" rather than 4".
Well, well, well. You call that midrange? Its response is droping like a rock below 1kHz! Some tweeters go lower. You were definitely ignoring what I wrote. Midrange driver is flat from 250Hz to 3kHz, I repeat. And it was said by others too.
Besides it has terrible rising distortion towards lower frequencies just as i measured myself.
But there is no definite definition of midrange frequencies, except they are in the 'middle of the spectrum'.
The quoted 300-300hz is the old telephone, voice reproduction frequencies.
that is no requirement or and actual feat that most drivers can even do.
You need it to be in piston mode
What is the problem with a rising response.
Often it just means that the driver is not rolled off by inductance, which does what? Distort the upper frequencies quite badly.
Or a smooth curvature, as long as SPL is high enough in the intended bandwidth?
Absolutely nothing, just requires a more 'complicated ' filter, as the textbooks solutions won't work great.
Absolutely nothing, just requires a more complicated filter...
Yes, there is no definition. I mentioned that in my first post. It all depends what source you follow.
Flat is preferred, but if the driver is designed with rising response, its fine with me. I used many planars with rising response. But typical cone midrange is flat. That is normal. If cone driver is not flat, than its defective.
I am absolutely ok if you use more complicated filter, its ok with me, you do not have to repeat yourself. You do not have to pay attention to what i am saying.

OK? "well well well"? What are you on about? Sorry I shared with your sorry attitude. It was not easy to utilize but I managed it. Paid off too. Not my fault you couldn't figure it out
