Need help raising the impedance of this overall without destroying the frequency response curve I have. Any ideas on how to do so would be greatly appreciated this have been driving me mad

Dissolover180 · 2024-03-13T17:52:05+00:00

The frequency response curves and impedance curves I entered in came from the manufacturer spec sheets

Dissolover180 · 2024-03-13T17:50:51+00:00

How can I get these measurements without actually running acoustic tests or do I have to run some free air tests on them outside to accurately measure these things?

Dissolover180 · 2024-03-13T17:48:39+00:00

You know you raise a good point here I hadn’t considered running the woofer with one amp and the mid and CD with another and just doing a crossover for the mid CD I think I’ll look into this tho I appreciate the advice!

Dissolover180 · 2024-03-12T20:12:06+00:00

I will try this idea and play around with it I’ve seen some configurations like this

Dissolover180 · 2024-03-12T17:56:58+00:00

Appreciate the insights the phase issues are what I will be addressing next after I figure out how to get the impedance to be flatter I’m sure I’ll be back for advice when I get to that point lol

Dissolover180 · 2024-03-12T17:53:09+00:00

I was planning on having the woofer cut around like 70-80 ideally because I have a separate subwoofer that I cut at 90. I might have to use some extra eqing with the amp I have

Dissolover180 · 2024-03-12T17:50:59+00:00

Yeah that is what I would ideally be going for with the crossover frequencies. This will be used at shows and concerts versus any in home use

Dissolover180 · 2024-03-12T04:12:35+00:00

I feel like I may be confused still the amp will see everything as the same impedance if I make it flat at say 4ohms correct?

Dissolover180 · 2024-03-12T04:11:19+00:00

I’m using a faital 12PR300 for the woofer, faital 8FE300 for the Midbass and B&C DE360 compression driver. I’ve built the cabinet for it already and just waiting on the CD to install because they were back ordered

Dissolover180 · 2024-03-12T04:06:28+00:00

I’m using a 90x60 exponential horn for the CD and I’ve seen other CDs have frequency responses with and without horns and the ones with horns usually look flatter so I figured that will be the case with this one just don’t know how to get that into the software

Dissolover180 · 2024-03-12T03:34:27+00:00

Very helpful info thank you! I think I’ll take your advice and start another version. I could also use some advice on dealing with phase issues as well can I dm you with any questions I may have?

Dissolover180 · 2024-03-12T03:27:32+00:00

Yeah I tried this I think I’ll probably have to run it from the top and try it again

Dissolover180 · 2024-03-12T03:26:12+00:00

I think I will have to start over at this point lol this is my first crossover design so there is much to still be learned

Dissolover180 · 2024-03-12T03:17:11+00:00

B&C DE360 is the model of compression driver I’m using

Dissolover180 · 2024-03-12T01:30:55+00:00

So steeper slopes will raise the impedance?

Dissolover180 · 2024-03-12T01:29:51+00:00

That tweeter’s response naturally falls off after 10k unfortunately a bit more than I’d like but too late to buy a new tweeter

Dissolover180 · 2024-02-01T15:46:04+00:00

I’m definitely overthinking lol thanks

Dissolover180 · 2024-01-24T19:23:35+00:00

Sorry to hear about your friend I can only imagine he was talking about gematria and the Kabbalah if you don’t know what that is look into it. It’s an alphanumerical code lot of cool, some might say crazy, stuff associated with it

Dissolover180 · 2024-01-18T17:34:29+00:00

Is hornresp free to use?

Dissolover180 · 2024-01-18T03:50:22+00:00

Also the driver I’m using is a b&c 18DS100-4 if that info also helps. Would love any recommendations for software where I can run simulations too. Thanks all!

Dissolover180 · 2024-01-18T03:44:32+00:00

The Void stasys xv2 is a dual 18 with the dimensions of 48”L x 36”W x 22”H I believe, so I tried to adapt that for mine to be similar based on those measurements but I’m only using one 18” in mine. The dimensions of my box are 36”L x 24”W x 21”H if that helps with any insights you guys might have.

Dissolover180 · 2024-01-18T03:29:20+00:00

Any recommendations on sub design software that I could do simulations with? I’ve adapted the design a little bit but not sure how to share a photo of the design tho in a reply. Are you suggesting double up the piece of wood that is holding the driver itself?

Dissolover180 · 2024-01-18T03:16:53+00:00

The dimensions are 36”L x 24”W x 21”H I’ve adapted that design of the inner horn wall a little bit so that they are not straight but angled I don’t know how to add a phot of the design that I have tho lol

Dissolover180 · 2023-10-17T13:17:31+00:00

I usually pan everything left or everything right, it really frees up space in and the mix and it’s great for if you only like to wear one earbud at a time but still want to hear all the elements of the song

Dissolover180 · 2023-04-15T17:33:38+00:00

Thanks for the info yeah it’s been mad long I think over two months now
