About midrange driver choice in a 3-ways speaker

I agree. It was funny you mentioned the 12 " woofer in your above post and thought your problem was with the woofer. I think the woofer does not go very low but found it the least objectionable part of the speaker. The tweeter sucks, the mid is meh. I used them for home theater and that was fine, I thought they could do double duty for hifi but no such luck.

you listened to the beyma system with what mid and tweeter?
ive had speaker with 12" woofers that i hated the sound of. notably Genelec 1037B and JBL lsr6332 with subs. I hated both of these system.
simply using a big woofer doesnt mean the speaker will sound good.

why use 600W with a hi-effiency woofer?

One of the steps would be spending €90 on some Behringer ECM8000 and UM2, add some cable and a tripod and just do it. Do your own measurements. Just my 2ct, most of us seriously considering Satoris, Purifis, Illuminators and the like could miss that amount of money just to get things really right.

having lived notable with Harbeth shl5plus, graham ls59, ref 3a decapo, which all of them use a 8" for bass duties

imo 8" is very small and give poor bass relatively.
imo, real bass foundation starts at 12'', arguably at 15"

Hi sorry for the belated reply but i am doing home cleaning 🙁
12" is a lot more than what i thought was enough This implies the 3 ways then
I have really to start simpler I dont see many 2 way bookshelf with more than a 8" woofer The consequence is that i will not get a full range speaker

Maybe once again, as this can not be said often enough:
If you want to design speakers on your own, you have to measure.
Not "maybe" or "maybe later", but an absolute first, before even thinking about taking a speaker in your hand.
Read and learn to measure. In that process you will learn a lot of practical things.
Indeed there is hardly any science where theoriy is that practical as in loudspeaker design ....

Hi yes i agree I was just watching a review with measurements of a commercial speaker intended for professional studio monitoring
It had some issues in FR response fixed with a new xover and some felt around the tweeter It was quite surprising for a speaker intend for studio monitoring activities They should be released quite perfect i guess They are tools for pros

A couple of nice 15" or 18" subs can be made quite cheap, it is very nice in stereo especially on some older recordings a single mono sub is simply not good enough, if you use some decent 2 way speakers for the rest you should be golden.
"There is no replacement for displacement."
Next year I will make some new subs, and some 2 way tops to go with. Starting to plan my signal chain now.

Hi thanks a lot But i have to start simple ... with the 2 way Then maybe in the future ... actually what you suggest was my idea from the beginning for a 3 way ... sat + sub I really do not know why people prefer big heavy towers I would cut all towers in the middle

12" + wideband. XO around 300hz. im building, as we speak, this speaker. PM me if you want more details
12" is to my mind a sure way to get real foundation bass to your music.

PS: im also building another 2 way vrsion using the same 12" woofer with a planar tweeter up top.

I agree.
The other thing I do not understand is getting "bookshelf" speakers and putting them on stands, thereby wasting the space that could be used for a couple of subs.
Stands are wasted material IMO.

hi thank you for the very kind and valuable reply So i am not alone Good!
let me say just one thing a little OT but not that much
There is a very telling test that almost NOBODY make also because you need expensive equipment
Placing a little mirror on the front baffle of ANY speaker and user laser to measure baffle displacement
Then send a very high level 50 Hz signal to the speaker and see
I am sure that the vast majority of baffles would shake in a crazy way
imho this is not very important for the bass
but extremely detrimental for the mid and high and the 3d soundstage rendition
for this reason decoupling mechanically the mid high from the bass can pay benefits expecially for the soundstage

Yes, sorta of knigths of the round table with a collection of holy cups already....What else.

Monitors due to their small front baffle often soundstages well, that is ok. For others a stacked sub with on top a monkey coffin is what to do, that is ok too...

Bah ...you know...the same with ladies, that is a state of mind:
Lady Guinevere
Lady Guiness
Lady Lema
Etc...

Me I like the omni sound of my mono Tv that radiate back towards the front wall...recessed treble and bass but very coherent sound. Go figure why...
