I'm in the designing phase of a 2-way setup with 1.4" CD and 10" Mid, with a passive crossover. My goals are 100-110db but prioritizing Sound Quality over anything. My last build (3way with decent drivers) was 2 years ago and I want this to be my final build and meet all my desires.
I intend on going with the 18Sound-10NW650 as my Woofer in a 1cuft vented enclosure tuned to 65hz, and the 18Sound-HD1480T CD with their XR1464C waveguide crossed at 800hz -ish.
I chose these drivers because I have a likeness towards 18Sound as a brand and grew up with the sound of their drivers, I've also had great personal experiences using their midrange drivers in a Car audio setting. That being said I'm not going to force myself to stick to their drivers exclusively if I have options that are far superior. I'm also considering the 18Sound-ND1460 and 18Sound-ND4015Ti2. From what I've gathered the ND4015Ti2 is much newer and also more expensive, I would like some input on if its worth it over the HD1480T. (Based on what I've read, I believe that it is likely worth it)
For the Mid I was also looking at the Beyma-10MC700ND, its more expensive than my intended 18Sound-10NW650 but it modeled similarly in a similar airspace. I would like input on if the Beyma driver would benefit me in any aspects of SQ over the 18-Sound driver. I intend to cross at about 70hz to my Sub.
For the Passive Crossover I plan on using a Linkwitz-Riley 24 dB/octave on both high and low pass. I did consider going with an active crossover since I use a MiniDSP Flex as my preamp but I don't plan on spending the $ on another MC7270 to pair with my current one, or buying new amps entirely.
I have no experience working with Compression drivers but have learned a lot from reading. Any advice for the build is appreciated 🙂

If you are looking at 1,4" exit drivers from Eighteensound, take a hard look at the ND3 /ND3S series, they are newer then the 1460/80 series and has a better phaseplug design, copper cap etc. The older series are a bit more robust if you need to use it that low.
But the 10" will be a better match with the horn at a higher XO point then you outlined.
If looking to cross lower you'd want to use a 14-16" driver normally.
As for drivers in the 10" category have you looked at the 10NTLW2500? Has a nice set of parameters/features.
Both that and 10MC700ND are fairly new, so there is limited experience with them.
The ND4015 will need a different horn or adapter as it is a 1,5" exit with a 4" diaphragm.
Better for a low XO.
Also do consider the N variants with TiN coating on the diaphragms.

After I posted this I did a lot more digging and realized that the ND3/ND3S Drivers, specifically the Nitride coated Ti looks really good and a really good choice for me.
What XO freq would be better for a 10" driver?
Thank you for the reply!
