Which type of speaker i would have used ?

Woofer = 8'' Tweeter = 2 1/4''



Its write TESLA on the speaker back, anyone know if its have a relation with my idol Nikola Tesla

Those look like fairly large boxes- you should be able to put just about whatever you want in there without too much trouble. The boxes look kind of flimsy, though, so it would be a good idea to add some bracing, and maybe double the thickness of the panels.

You probably want to flush mount the new drivers. Can you give us the internal measurements. I bet your fellow Canadian Planet10 can probably direct you to some nice vintage drivers that would be suitable.

Hello

Tesla was a company from Poland (at least that what I know) that made a lot of speakers during the 1970's and 1980's perhaps even more. I have a pair of an old Tesla speakers that sound amazing even if their so old (these were sold in Romania with a magnetophone or magnetic recorder ). They are very sensitive. You should improve the cabinet before mounting other speakers because Tesla are not so powerfull. I have a 5.5 inch, around 15cm, woofers and 2 inch tweeters that are only 15 watts (at least that what was written on the woofer) but they sound unbelieveble.

Regards,

Andrei

Personally I would just bin the whole lot unless you really need to keep them for nostalgic reasons. I can see straightaway that the port has been done before people really knew how to do ports properly. The cabinets are nothing special and look a bit rubbish in my opinion.

You can make better yourself, especially if you have to buy new drivers. Things have come on a lot since the 1960s.

If you insist on keeping the cabinets, you would need to fit a port tube that will go in the hole already there, or just make it a little bigger to take the new tube. You would also need to add a good amount of bracing.

I was going to point that out...

Yours are Model 666?

These are quite a decent budget vintage speaker. Best put in an open baffle IIRC. The boxes they came out of a only worth burning.

I think i have a spare one of these that needs some remedially attention to the lead-outs.

Found some data... depending on how well they have aged, looks like they will need bass support....





These definitely don't want to be trapped in a box.

Fs 134.28
Re 6.50
Qms 10.93
Qes 1.55
Qts 1.36
Vas 13.30
Cone mass 7.41
Sd 222

(Vas done using added mass method Note: the low voltage computer based. T/S measuring kit produces higher Fs, Qts, & lower Vas values than techniques that use higher voltage drive.)

Thanks for your reply, but i will follow the commentary of 'richie00boy' and did not spend any cash for those box...

I found this site on the forum Frugal-Horn and envisage to build the '' The BVRs 8'' (Bruce) ''. I will have a BETTER sound quality and great looking box.
Do you think its a good idea ?

Thanks
