I've been wanting to build a new set of speakers for my living room for quite some time and since I've finished my other project (my car) I'm moving on to this.
Plans are for an active 3 way floorstander with...
sb acoustics sb26cdc as the tweeter from 4k and up
Zaph za14w08 5" mid from 200-4k
Dayton dc250-8 10" woofer from 200 down ported and tuned to 30hz
Cabinet will be treated/dampened.
My main questions revolve around driver choice and interaction. Do you think something else would work better for around the same price per driver? $40-60ish
Or does someone foresee a possible issue from these plans?
Crossovers are tentative depending on driver and room response etc. May change those a bit.
Thanks for reading and for the help in advance [emoji846]

?? are you going active or passive? saying that the x-overs are tentative suggests a passive design and with no mention of amps it is a little unclear...
a mini dsp xover would give you freedom to tweak, with no parts cost....
then it's down to amp modules for each section of your 3 way.

Sorry, crossovers will be active electronically.
I have a dayton 408 and might get a minidsp in the future.
my amp is a denon 7.1 receiver that will have its channels routed from the dsp.

I would cross the Zaph to the 26ADC a bit lower, around 2-2.5k just looking at the beaming of the Zaph at 4k. The 26ADC can handle it easy.
The 10" to the 5" should be alright around 300hz considering the baffle width required for the 10. Remember you will need to push the 10" about 3-6db hotter to match the output of the 5".
That's the beauty of active (if DSP) crossovers, easy to change.

No joke, I love being able to easily level match.
I'll keep that on mind on the zaph, I noticed the beaming issues around 4k originally and planned to crossover below it. But that might screw up past the point.
Thanks!
I had originally considered the Tang Band W5-2143 (paper cone, also a 5 inch) alongside the zaph, anyone know anything on it?

Just realised I said ADC and not CDC, but no worries there’s not much between them. What are you cabinet goals and what amps using?
No experience with TB drivers sorry, look cool though.

Sorry, what do you mean by cabinet goals? Still new here, you mean the sizing of it? Airspace?
Amp is a 7.1 denon receiver I have that has preamp inputs I can feed the processed signal to.

cabinet size, type (closed, vented, ob) or separates for each band would come to bear.
as to the differences between a passive crossover driven by a single amp or a multi-amp active crossover i'd say the differences are night and day...

That kind of difference, meaning how can you tell whether a designer will plan and measure, or simply tweak based on where in the chain they put it.
Size, roughly 14" wide, 48" tall, 11.5" deep.
Woofer gets 2.5 ft³ ported to 30 hz with two 3 inch flared ports and the mid gets .15 ft³
I'd probably have to do a separate for the mid but if it's beneficial have it share the same front baffle.
What's the reasoning behind passive vs dsp active? One of the reasons I'd prefer using the dsp with what I have is cost and I'm familiar with using and tuning them. If it's a matter of not using and measuring dsp responses then I'm fairly methodical. Wouldn't just slap on some LR4's at points and call it done.

You should take a look at the SBA SB15NBAC30 and SB15CAC30. These are very high performance 5" drivers considering their price. The NBAC (aluminum) is ~ $65. The CAC (ceramic/aluminum) is ~ $80.
I used the slightly larger version SB17CAC35 in an active 3 way last year, mated to an SB26CDC tweeter.
New active 3-Way, Hypex and SB
I have been very impressed by the performance of this driver.

Don't show me those pretty white cones [emoji854]
I'd seen some testing of the sb ceramic series and they seemed really nice. I could probably swing that for them since they also have similar sensitivity to the zaphs, just dont want this to end up like my car where I had a planned budget for speakers, dsp, amps etc and then changes and then an annoyed wife comes into play [emoji55]
I'll model them and see what enclosure sizing they like

sorry for the "side" conversation but clear me up here....a loudspeaker with a passive x-over with DSP eq applied is one thing, but a loudspeaker with a DSP outputting to a multi-amp configuration is quite different no?
Actually, it is more alike than different. Especially at this early stage of planning. RyuTsuiSen is trying to select drivers, approximate cabinet sizes, approximate bass tuning, and approximate crossover frequencies. At this point, the decision process is the same for active DSP and passive. The drivers must complement each other in dispersion, power handling, useable frequency range, max SPL capability, distortion ... As an absurd example, trying to mate a 15" subwoofer to a 1" dome tweeter is a recipe for disappointment, active or passive would make no difference.
The one way that passive and active differ in the planning states is that with a passive speaker the designer must plan for how the driver sensitivities will work together. Tweeter and mid sensitivity can not be increased, only lowered. Woofer sensitivity can not be altered (generally speaking). With active on the other hand, the gain for each driver is simply dialed in.

fair enuff... likely a result of narrow thinking on my part but in the passive format/version don't you lose the ability to vary the slope of the curve of the x-over?
If you mean after it is built? Mostly Yes, once it is built, it is hard to modify a crossover in a way which alters the slope. Not impossible, but hard. Most of the tuning of built crossovers involve changing resistance values.
But in the design (simulation) phase, a person can vary the slope of the crossover from 1st order to 4th order, typically.
I feel like I am not answering your question ??
