Have you heard the Beolab 90?

Idk if it’s 25 hz but James Blake Limit To Your Love will give your sub a solid workout.

Yup I agree with you.

I still haven’t learnt passive XOs since I knew from the beginning I will go the digital route.

Also if you look carefully you will see the dust cap on the mids are the same shape as well, the entire voice coil and motor assembly behind them are also elliptical shaped. Hence, Ellipticor. They claim it’s revolutionary, all I can say is that I don’t have much experience with high end speakers and it sounds good to me.

You don’t have to do that crazy, you can absolutely create a top tier design using less expensive components.

But yeah, it’s a simple two way ported bookshelf right now with a Dayton Ultimax UM 18 sealed 5 cu. Ft. subwoofer. The tweeter is a D2404 and the mid is a 18WE 4 ohm version. Active XO is not finalized since I keep playing around with the settings almost every week. Messing around with the slopes. Mostly looking at a 2nd order around 3000 hz.

There is a lack of mid bass but that is a given due to the small drivers which is why I will add more drivers later on for a 3 way or 4 way.

But since this was my second project after my subwoofer I wanted to see what it’s like before I drop insane cash on a 3/4/5 way design.

My source is a Computer which also does all the XO using EQ APO, which feeds into an AV receiver with HDMI. The drivers are wired using individual channels so like the mods are FR AND FL on the AVR. The tweeters are SL AND SR. The AVR does no processing whatsoever. I use a UMIK-1 to measure in room response. A measurement microphone is critical IMO.

Let me know if you need more info :) glad to help. I had the same problem, didn’t wanna drop 50K on speakers. Didn’t know what made 50K speakers so special. Took some figuring out but now I know almost everything about loudspeakers. It was worth it.

That’s exactly what I did, I went with all in with Scanspeak Ellipticors Active XO. Can’t beat that in my book. Linear phase, wide dispersion, all the detail you can ask for.

Source has to be top notch otherwise it’s gonna stick out real bad. Took a while to finalize my design and learn how to do it but I had time.

Hey! If you’re up for it, you can always DIY your loudspeakers. At the high end you can make yourself something insane using the best components. You will need woodworking skills and some basic soldering. You could possibly even hire a woodworker if labor is cheap where you live.

A great entry for you would be a kit. Since designing your own would be quite difficult. Diyaudio.com is a great site.

Depends on the speakers. But generally speaking yes. I switched 20 years ago, never going back to TV speakers, or for that matter, uncalibrated displays, untreated rooms for sound reflections, etc etc the list goes on.

I even got a measurement microphone to measure and see how the system is interating with the environment and have optimized it for the room. Night and day difference over stock.
