70's Cable radio Speaker to Bluetooth Speaker

[vvvyper]

Hi All!
I am ANtonio, an italian guy, and I discovered your forum! Fabuolous! I think this is the place for sharing my new passion for repurposing speakers.

My first project is turning this old 70's cable radio speaker into a good quality speaker for portable mp3s, ipod and so on, with both jack and bluetooth connectivity. I was thinking for a T-amp as amplifier, like Dayton Audio DTA-2 or something TA2024 based.

My question about driver:I want to replace the 3"x5" with a really good full range speaker...but with which? I don't find other 3"x5"..maybe it is better to use a normal 3" like HiVi B3N or Tang Band W3-881SJF?

Is there anything wrong in my question? IF you say me what to change, I can do that!

Nothing wrong with the question. Sometimes it takes a little while to get answers.

What are dimensions of speaker box? Is it sealed or ported? Is it stereo or mono? Since you are suggesting 3 in driver I would go with a 3.5 in if room allows. Use a Vifa TC9FD driver great sound and great value. You might want to check out rectangular or square shaped flat drivers (Balanced Mode Radiators). You might have room for two and do stereo. I would go with a TPA3122 amp rather than TA202x. TI's sound better in my opinion.
Hope that helps v

Thank you very much Pano, xrk971. The box is 4.75" x 3.5" x 4.5", sealed (but I could open a port if you seggest me where ).
You see in attachment the front back. The "drilled" area is 2"x4", maximum allowance is 3"x5". Maybe 3.5" is too much...what can I look at? Good idea having a stereo" maybe 2 pieces of maximum 2.5". What do you think?

 

[Pano]

cool. Maybe we could change the title of your thread to something that will attract more attention.

You might be able to squeeze in a pair of these. Visaton 2.5 Inch 8.0W 8 Ohm Full Range Speaker | FRS7 2012 | Visaton

Use this amp. http://www.parts-express.com/pe/showdetl.cfm?partnumber=320-329

Let's say that I can spend more, say $20 each speaker and $20 for the amp. I have a real different choice? Or the quality can't be so better?

 

[xrk971]

At $20 for amp, the TPA3122 will give you more power (15 watts) but if you are only using 2.5 in drivers you won't need more than 5 watts. The TPA3110D2 for $10 is an excellent sounding amp. You might want to look at Tang Band 2 in drivers if you can spend $20 ea.

My first thought is that it's a pity mangling such a beautiful radio.
I can't pin down the designer but it looks something like the Brionvega stuff from the 60's and 70's. Are you sure you want to do this if it is working alright or if it can possibly be repaired?
Regardless of what you think personally, it could be worth a lot (as opposed to nothing if you go ahead with your plan) in resale.

 

[vvvyper]

Wonderful question. For repurposing, I use ONLY very damaged pieces, where external is ok, and internal is to trash I perfectly agree with you! It is from Zanuso.

 

[vvvyper]

SOrry guys..I can't find Tang Band 2.5".. quat do you think of Dayton Audio ND65-4 2-1/2" ? Or something else form PE..

 

[xrk971]

The Dayton is a nice unit - terrific deep bass for how small it is at expense in efficiency and high freq performance, The Vifa TC7FD is nice too for this application, If you want clear vocals and brilliant highs go with Vifa, deep bass go with Dayton ND65. You can get PE in Italy with reasonable shipping?

 

[vvvyper]

Just controlled....minumum 46$ only for delivery I have to search for other suppliers in italy or europe...
