My understanding is that the 6.5 inch will be better for midrange and voice spectrum and not so good for bass whereas the 8 inch driver would be better on the bass but lose out on the midrange and voice.

Size doesnt always matter.
Fane do 12 inch full rangers up to 17KHz.
Its down to number of cones and T/S parameters.
Was trying to stay away from expensive drivers, and I had a feeling someone would say that actually!

Silver Flute W14 is a real bargin, and performance is good (used prs in both a miniOnken and the Tysen v2 ML-TL.

That really doesn’t look like a 12” full-ranger that was mentioned previously, and what I had responded to now does it?
That is a nice, reasonably priced speaker, but I’d bet that a single 6.5 would best it in this application.
I’ll stand by what I said in that a pair of 6.5” would cover the spectrum better without resorting to a subwoofer.

For years, I had two way passive speakers with a Peerless 8" and Vifa 1" tweeter. Because of what I had read, I decided to convert them to active. This made an audible difference. I then thought, why not put in a mid so I added a Peerless 5". This made a bigger difference making the midrange clearer and more distinct.
As you will be going active, my advice would be to seriously consider adding a midrange (4-5") for a little extra complexity. It will be worth it.

Thanks,
Are you able to list the speaker driver numbers you used and say more about how you implemented the active side? Do you have any pictures?

I used the following (using an UK website, if possible, to show availability only);
1" tweeter Peerless Vifa XT25BG60-04 Tweeter
5" mid 832873 Peerless By Tymphany 5" Mid-Woofer Hds-Nomex, Peerless | Wagner Online Electronic Stores
8" woofer 830869 Peerless By Tymphany 8" Woofer Hds-Nomex, Peerless | Wagner Online Electronic Stores
The crossovers were from ESP (Rod Elliott) P09
Linkwitz-Riley Electronic Crossover
The amplifiers were also from ESP P19
Single Chip 50W Stereo Amplifier
I sold the drivers and boxes so am unable to provide any photos. The boxes were bass reflex (ported) rectangular in shape with a length of plumbing pipe as the port, simple to make.
With the abundance of cheap Class D amps, switch mode power supplies and a variety of ways of doing crossovers, it can be done at a more reasonable cost and lower complexity than mine.
There are also a variety of combinations of speakers that will match the above, such as;

With SMPS (switch mode ps), complexity of power supply is greatly reduced and many also come with +-15V DC for crossovers etc. Just order it with the correct voltage/s for Class D amps and I would use all the same or get a unit with three amps on the one board. Use modelling software to determine the size of the box (or use the recommended size on the Madisound website).
Happy to help further, but I have to say it will take some work and you must have some familiarity with electricity and its dangers. If the latter is a problem, don't die for a hobby.

How does it compare to a DSP with that crossover?
My knowledge is limited, but I'm thinking it would require drivers that is well matched even compared to a passive crossover.
But I do find it interesting, so if you have any further insight I'm interested. 🙂

You might be interested in this blog post I wrote with measurements. 🙂

With a good room/room acoustics the right 6.5 can sound pretty great.

I can't see any reason to use other than well matched drivers with a reasonably flat response. Anything else is inviting known problems that may not be easily solved, if at all.
The crossover has level adjustments and works well. I am about to embark on a DSP adventure so will soon see the differences, if any.

Thank you for your respons, and I see your point.
I guess the level adjustment should solve any resonable problems that you might see, and if it can't you might be on the wrong path. 🙂
I'm more at the beginning of my journey I guess, so I liked the simplicity compared to a passive cross over and will keep it in mind.
Thank you for your respons! 🙂

Modern manufacturing being what it is, I expect nearly all drivers to be well matched, regardless of price. Am I wrong?
You are wrong. I measure lots of speakers. The best ones hiy less than ±10%. Less strickly QCed brands can exceed ±20% and i have seen examples of pairs that measure as if they were 2 different drivers.

Sorry for the confusion, my thoughts was more in line with cone break-up or uneven respons. I believe it's called notch filters(?) that's used in passive cross over to correct some of this.
I'm guessing DSP is easier when working with these kind of problems, especially if they have the ability to run FIR.
I might be wrong, but from my limited experience it seems like there are more modern drivers that has these 'nasty' habits, perhaps due to modern solutions to combat it and in the end get a superior product.

Oh, those. It's about the same. In the passive world you use a simulator like XSim. With a DSP solution you may have an easier time testing it live, and adjusting in real time.
My bit of advice : Dont' fix driver problems with speaker EQ. That is, use the parametric filter that goes to the mid-woofer to fix mid-woofer problems. Don't leave it in and attempt to fix it with global EQ.
6.5" woofer and 1" tweeter cross at 2000Hz.
I have always used full range drivers.
Gets rid of the complex world and price of crossovers.
to the OP - If you can only listen at low volume levels here is some information on the effects of volume on the frequency response. Loudness and Level - The Difference - Soundbridge
I always wondered why speakers can sound fantastic loud and thin when quiet. This explains why they put a loudness button on the marantz. I always thought it was to make loud rock louder but no it is for quiet listening.
