[Olivetta]

ok:

the Funtek fe85 cost 16€

the TC9FD18-08 cost 19€

the Funtek fr88 cost 36€

the Visaton B80 cost 50€

the scanspeak 10F/8414G10 cost 60€

the Markaudio 6m cost 70€

I have to build 10 speakers the cost it could be not a problem but if there are no big difference i do not like spoend three times

what speaker do you sugget?

other question

do you think that it could be possibile find a driver like 130mm that could work with a small volume?

thanks as always

Matt,

Your link is to a webpage, not a picture so it is not showing up.

4L for the P7 is a little less than optimum but still fine. I’d guess an F10 of near 60 Hz with a small bump before it starts rolling off.

See attached. Do note that these sims are without damping. Damping can increase the apparent volume up to about 20%.

Thanks dave, I think technically it is 4.3L, and I plan to add a little dampening too.

here's the design.....

cabasse io2 stands - Google Search

thanks

Well....with DIY you can make whatever you will/want !
Problem with audio is... the final product sounds good ?

I saw the minionken
They are to depth 30 cm......no way

I need something like 10cm max less it is could be better

Essenziale I want something with the depth of the ap

This is it exactly my question and why I am asking your help

 

[MattSug]

This is it exactly my question and why I am asking your help

I think this is why it is maybe a good idea to try someone else’s design as a first project. That’s why I decided to take this route.

 

[Olivetta]

do you have same suggest?

 

[MattSug]

post #23 mate, I attached the design I followed on there

 

[Olivetta]

is it ok for the fountek fe85?

 

[MattSug]

is it ok for the fountek fe85?

I've no idea, but I doubt it. This design is based on the Mark Audio Pluvia 7 driver.

[jimbro]

Parts Express has cabinet suggestions for all the bass or full range drivers they sell. Check there and you will see the fountek fe85 f3 spec at 196 hz in a sealed box. Won't do at all for MattSug's design.

 

[Olivetta]

checked




but if I understand correctly the sugget close box is 0.02ft3 that it could be 0,556 litri


it seems to me litle small or i understand sometingh wrong?

 

[Olivetta]

and if we will see the vent box it could be 0.05ft3 thata it could be 1,45L


that it is so far from the 2,7 litre that it could be work great

 

[jimbro]

Modeling software is used to determine the appropriate box size. Some may stray from the recommendations based on experience and need but generally for a beginner you should to trust the software IMO.

 

[Olivetta]

Ok but from the data sheet how I can find the dimension of the vent tube and the position of the ap?

 

[Olivetta]

I've no idea, but I doubt it. This design is based on the Mark Audio Pluvia 7 driver.

Jus one information

I saw that the Fountek 85cost 16€ and the pluvia 7 it cost 60€ there is a real reason like so much better or only different taste?

 

[planet10]

The P7 is a decidely better driver, one with much greater bass potential. But it needs a larger box.
