"Tired2way" speaker building.

I take that as you have enjoyed this thread, RCruz. Now with some time since I did my last fine tunin I do not think about the sound very much, I just enjoy listening. My next project is slowly taking form....

 

[RCruz]

Yes... enjoying it very much... thank you

Me and a friend was listening this weekend and he said he missed some of the clarity from his speakers mid range. Is there a way to maximize mid range clarity, how much depends on the driver itself and the cross over and speaker box?

 

[fatmarley]

I think you need to build a 3-way speaker.

 

[Starre]

Yes maybe, I have been thinking that too. With one driver for both bass and mid range it is probably harder to get that ultimate mid range clarity, but I am just speculating.

starre,

you both got the same DAC? or same turntable? i noticed very big leap of clarity when i changed to better DAC.

The smaller Tannoy DC drivers (10") do it IMO, but they use a large, horn-loaded tweeter.

EDIT:

Tannoy high frequencies aren't the best though.

 

[Starre]

henry, no he has more advanced stuff, so yes it should be better.
Hard to get it all then, fatmarley.

 

[Starre]

I will try with a better cd-player to see what happens. I can borrow one.

First thing you should do is to listen to the speakers in the same room.
How do you know his speaker/system is the better one?

price/performance of ca22rny and D2608 is exceptional!

Is there any measurments/simulations of the speaker?
on and off-axis?

Here is a simulation:







The simulation shows indeed a little dip in the crossover region. After removing the 2.2uF capacitor in the woofer section it looks better:







However this kind of fine tuning is beyond the accuracy of the simulation. But you could try it and find out, if this modification improves the midrange clarity...

 

[schmutziger]

i dont think the dip is a negative thing, it is rather a feature
looks like dispersion issues in the 3-8kHz region
tweeter a bit high over 6kHz? attempt to get a nice energy curve?

 

[Starre]

My own measurings does not show a significant dip around 2kHz and a rather even treble and the tweeter never sounds unbalanced beeing to high in level. I will try my friends cd-player to compare. Thanks for the post Dissi.

Here is a simulation:

Dissi, nice program you have made there. Set the mic axis between woofer and tweeter flanges for this one though, its the way it was made to stand against a listener at seated height.

 

[schmutziger]

ah, so it is not only the crossover you simulated?

 

[Salas]

Its a made, measured, listened and tweaked to preference real speaker we made back then. Not just a sim.

CD-player booked for a listening in about 10 days, back later with impressions.

what kind of cd player? any update?

 

[Starre]

Audio Aero Capitole MKII. It is getting a little old these days but is still a vg cd-player. It is for sure better than my Naim CD5X.
I read a post on this forum that the coil used for the woofer in a 2-way can affect mid range clarity. I used this non-ferrite cored one: JANTZEN-2005 - Jantzen Wire non-ferrite cored coil 2,500mH 0,268Ohm 1,20mm - Europe Audio
Maybe a better coil increase clarity but I can not test this and they are expensive to buy.
I will report if a better cd-player makes a clear difference when I have tried it.
