Is the ideal multi-way a 3-way with limited bass?

Hear me out here.

3 way speakers with the traditional large woofer benefit from high bass output, and improved midrange clarity due to the lack of Doppler distortion affecting the mids, but with a lot of modest listening areas the big woofer can also be detrimental.  They produce too much bass, which together with room gain and room modes causes flabby and exaggerated bass.
So, lacking ARC or EQ capabilities perhaps the best compromise for the purist is to have a big woofer 3-way but with a limited -3 dB point, say 45 Hz or so.

45hz and down is a good place to start... NOW get rid of all of it...
unless space is a serious issue. 250-300 hz and down.

The larger the driver surface the more prone it is to distortion. IF you control what comes back to hit the cone surface (phase plugs), AND narrow the driver baffle surface, thing change a LOT in bass region.
Larger drivers work great.  Still have a baffle to contend with. It's hard to make that box go away.. I'll give it a -6 not -3 for baffle (bass) gain, with a 6 db first order. 24db with a low notch maybe a -3  (the baffle is a pain). and a huge contribution in the distortion column.

I'll try it.. simple enough.  Opps, Forgot.. I already did, yup sure did...
separate boxes and columns, MUCH better SQ, just a bit more real estate.

Your speaker description reminds me of the monitors of 70-80, huge bass drivers, double mids, double highs.. I still have a few.. QSO 808s by VMPS..

Infinity with their SM series...they were everywhere...

K, now don’t mix the pills up again. That’s one red and one green, not the red and green, that for constipation... ;-0

10 is way to many any ways.. I’ll try 5, can we cut a deal on that and go for a flat, two and a studer?.. Da, da ,done!

Control yourself man... LOL This is a pubic, bone.. ops...Public, forum!! :-)

One more thing K... The doppler, is transient, not all speakers do it, but it's real just like lobing, ringing and all kinds of design issues...NOT addressed by every speaker designer...$$$$$$$ is money right... Stuff cost money.. You get what you pay for sometimes.. or better yet Make for yourself...
