Diy PA speakers out of old car speakers

[NIXIE62]

@NIXIE62 hmm first nice to see someone from serbia. Second idk if sal drivers are good now i saw some guy making boxes for them but idk maybe the Martin Wisman HPLX 18 is better but i can find a little about them.

SAL is China, so is Martin Wisman. They have some minimum quality and can probably be of use to you if you want to get something cheap to start with. You need to simulate the box in some program for any driver. For this 4050, I think only compression box is suitable.

If you want something better (and more expensive), there is a lot to be found here here, for example Eminence. There are also various used drivers, you just have to be careful.

i dont have my pa and ... I was thinking that I could build a pa system out of them

Buy real PA, second-hand are cheap. It will be vastly superior to any car-speaker hodgepodge.

@Galu alr i will do that and then send some photos of them when finished.

@NIXIE62 hmm i did looked at Eminence and thwy have pretty low xmax like 4.8mm. Maybe for the subs i best to get a original rcf driver? The tops i think that if I will be making tops that Eminence and identical drivers will be fine.

@Sonce I know but i have this drivers for quite long and they will be serving me more as a boombox than a pa system. And the used market is not that good.

@Galu or anyone what do you think about the t rack ds 2/4?

Edit here is a pdf manual with spec and other Link

 

[Galu]

The t.racks DS 2/4 is a Digital Loudspeaker Management System with 2 Inputs and 4 outputs. Costs around £150.

I'm afraid that's the extent of my current knowledge about the machine!

@Galu here is some more information
It has Three digital 24-bit signal processors
Parametric five-band equalizers
High- and low-pass filters
Controllable input and output sensitivity
Runtime delay of up to seven seconds
Limiter with adjustable threshold, attack, hold and decay
RS232 interface
now i can get it used for a 70-100e it says to cotact seller for price for me it will be enough i will use it for listening music and for pa systems i think that i will never use like a 3way or a 4 way system only like 2 way tops and subs.

What is that in Pounds Sterling I wonder?

I hope you will be able to check that this complicated piece of electronic equipment is fully functional before you buy it.

My main interest lies with vintage Hi-Fi, so no doubt you are more knowledgeable about this device than I am!

@Galu what do you think that i make a tham15 subwoofer box and use it wirh those spekaers and later upgrade to like 10 or 12 inch tops and later got to 15 inch tops and 18 bass reflex subwoofers?

The THAM15 compact 15" tapped horn?

I see there's a long thread about it: https://www.diyaudio.com/community/threads/tham15-a-compact-15-tapped-horn.175658/

I can only say that this may be suitable for use with your 6.5" driver tops until such times as you can afford to upgrade the entire system.
