Heck yeah!
Above and beyond any kind of static compensation; via passive, active analog, or DSP...
i super strongly use/recommend, real time adjustment of CD's output, either through simple level control or simple shelving.
You guys do realize how much tracks vary, beyond "artistic intention", right?
Tone controls work ! 🙂
Yes, absolutely. Leveling of the response has to be done in the crossover or the EQ. Won't sound right otherwise.
For those of you who have used the Celestion Axi 2050, at what frequency did you apply EQ, and at what level of boost/cut did you find worked in your application?
I realize that this is also dependent on the waveguide/horn that the CD is used with, so if you can also indicate what one you used.
Thanks......

Oops! I'm 900 miles from home so I didn't check before posting my comp network. The 7 mh / 8 ohm network is my baffle step comp for the woofer. For the CD, I use a .47 mfd capacitor and a resistor network.
You have a miniDSP, right? I would start here:
https://support.minidsp.com/support/solutions/47000523305
Read through the basic concepts and there are specific product articles also. They might have videos, I haven't checked.
In your specific case, with the BMS driver, what is happening is that your woofer is putting out sound at a much lower level than the compression driver. The compression driver kicks in at the high frequencies and because it is much louder you don't hear the lows. When you turn down the level of the compression driver in miniDSP, it will sound better.
We can't get into crossover design here, but maybe if you start your own thread, folks will jump in with helpful suggestions. Read up on some basics on the miniDSP pages and go from there.

Hello,
I have been designing 3 way active speakers for more than one year now.
The faital hf108r plus sth100 are a delight, I love them and I think they blend really well with my PHL 1140 plus JBL midhorn.
But now that I changed all my amps for audiophonics purifi amps, I wonder if I could try another compression horn combo (one inch).
What is the best new 1" CD of the topic ? 😁

You already have them ;-)
Maybe go the opposite direction and try a hard dome like the NSD1095N. Some say they present a more detailed sound than a plastic dome...others say they sound metallic.

Yeah you are right, I listen and compare to my headphones plus mojo2 plus morphit and everything is so close.
Except the hifi system is capable of live sound and imaging 👍
I use audiophonics purifi amps in by pass mode (only final purifi 16db gain) and this is awesome, I highly recommend these. The dynamics are superb because it is capable of true silence.

Add DE360 to the mix - I would say these are the top notch 1" drivers for reasonable money.
NSD1095N does probably both - give more details and sound a little metallic at very high frequencies. DE360 is "relaxed" without a lot of resonances.
A listening comparison between these 3 would be very interesting ...

On paper, the DE360 looks like one of the best 1" drivers available.
But this test comes along and makes me wonder if I would hear the same differences.

Also the NSD 1095N is not really any better then the NSD1090, worse in performance in some ways.
!8s Nitrided diaphragms looks like they perform the best in they're ND3 range.

A low shelf filter to cut the horn boosted mids to near nuetral, from there maybe 3 peak filters to iron out the response to get about +\-2.5db. This is on a 160hzF3 elliptical tractrix horn.
Thanks for replying....can you elaborate? What are the frequency's you applied the various filters, and what level (ie: 3k -4db , low shelf, etc.).
I realize that your filters are based on your specific horn, and won't generally translate to the one I am using ( Yuichi A290).

Why don't you just look at the raw response and get it over with? From there you can theorize the route you might take to get the voicing you desire.
With about 6-8 filters I created this indoors (1/12 smoothing).
First measurement is at 1m raw outdoors. 2nd is 1/12 smoothing indoor. 3rd is raw outdoor with about 3-4peak filters, and a ~200XO.. possibly 24db LR.
I'd have to hook up somethings to be more specific. When that happens, I can share the details. Those are 2db increments in the graphs. At 8khz is the largest deviation at +/-4db. from about 7khz to 200khz not much going on. Just a matter of bending the trend in the right direction.
Can anyone recommend a drop in replacement for the 15 inch woofer in the Altec Valencia 846B ( 8 0hm) speaker?
Thanks.....
Thanks.....
Any thoughts on how this B & C NDL88
15 inch woofer might work as a replacement in an Altec Valencia 846B?
Is it possible to archive 0.145 ms delay with a passive x-over for the tweeter to time align the 4592ND?
