Hi.
I am looking for a DIY speaker design to use in my HT for L, C, R and surrounds. I need them to be powered by an standard AVR, so 6ohm+ and good sensitivity is needed. I do not need high SPL as most listening is donde
The thing is that I live in South Amercia, and here we don't get most speaker brands like SBacoustics, Dayton, Vifa, Tang Band, Peerless, SEAS, Scanspeak, Eclipse, Morel, Hivi, etc. So most DIY speaker designs I find over the internet are not possible without expending a fortune (twice+ the price of the speaker) in shipping charges and taxes.
Here we are moslty limited to some PA brands like Eminence, 18sound, RCF and FaitalPRO, and even there we don't get all the models. I can import some tweeters or compression drivers, as the shipping should not be as expensive as the woofers.
So, based on these requirements, do you know any speaker design that will fit the bill?
I've checked in many forums, and DIY pages, but found none with these specs... I did found a design using the Delta 12A, but it required a Horn that was not available anymore.
Hope you can help me. Thanks

Hi!
Could you give some information on the type of loudspeaker you are after:
Sealed box or bass reflex?
2-way or 3-way?
Physical size?
Thanks.
EDIT: Home Theatre, left, centre, right and surrounds? - Quite an ask!

I do have 2x Dayton Ultimax 15", each on a sealed 3cu.ft. enclosures, so I might noty need that low extension on the speakers, so sealed could be OK, but if bass reflex is available, I have no problem.
I think a 2-way it's easier, because as I can't get my hands on too many components, it's best to get the woofer locally.
Top limit on size should be around 40cmx40cmx100 (wxdxh) for each.
Thanks!
Thanks for your reply!
I thing sealed it's OK, because i already have 2x Ultimax 15" in 3cuft sealed enclosure. Enough bass for my and my neightbors (i live in an apartment). Bass reflex it's ok also.
2-way should be OK, as I am limited on the type of drivers I can get.
Maximun size should be around 40cmx40cmx100cm (wxdxh) or same volume size... give or take.
Ok, you are right... maybe asking for L, C, R and surrounds it's too much. Maybe I need to start for L and R channels, and see where it goes.
Thanks again.
That is a good starting point.
Hopefully now someone can come up with a 2-way, pro-driver match for your sealed 15" woofers.

Look at co-axials. Eminence are inexpensive, and then the price ramps on up. I am listening to some Radian 5208C 8" with stock passive crossover which surprise me with their detail and lack of aggression in the treble. Pretty efficient as well.

Can't find any coaxials from Eminence in my country...
Here are some of the drivers I can get my hands on:
Eminence | DELTALITE2510
Eminence | DELTAPRO12A
Eminence | KAPPA-15A
Eminence | KAPPA-PRO15LF2
Eminence | KILOMAX-PRO-15A
Eminence | KILOMAX-PRO-18A
Eminence | BETA12A-2
Eminence | DELTA-12A
Eminence | DELTA-15A
Eminence | DELTAPRO15A
Eminence | DELTAPRO18A
Eminence | KAPPA-15A
Eminence | KAPPA-PRO15LF2
Eminence | KAPPALITE-3012LF
Eminence | KAPPALITE-3015LF
Eminence | KILOMAX-PRO-18A
Eminence | LEGEND-BP122
Eminence | RAMROD
Eminence | SIGMA-PRO-18A
I am assuming that you will be using the 15" drivers in their 3 cu ft enclosures to reproduce the low bass frequencies.
In that case, the drivers in your L & R speakers need not be as large as 12", 15" or 18".
So, of the Eminence drivers you have listed, the 10" Deltalite 2510 would be the better candidate.
Being a 10" driver, it will also allow a narrower enclosure width then the maximum 40 cm you have specified.

Afraid not - I am flying completely blind here!
Simply trying to advise you within the limited range of driver choices you have given.
EDIT: Have found these enclosure details:

Thanks for your help. The thing is designing the XO for the components, too much knowledge and science is involved.
I've found a dealer that have 18Sound, DASaudio and B&C speakers. Maybe some speaker designs with those...
Have a look at this: 3 way bms4550 seos 10 bms 5n160 faital-pro 8pr200
You will have to read everything, as the final project is very different than what was initially planned. Somewhere around the last pages you should have all the details, including cabin sizes, complete crossover schematics, etc.
Its not finished yet, but it will be a hell of a speaker, and you should be able to get BMS and the Faital drivers locally. The SEOS 10 may pose a challenge, but you should be able to get them from the USA for a reasonably price.

neo2015 thank you for your reply!
I will read the entire thread and see what comes out. Sadly, my first look for BMS drivers here in my country delivered no results. Will keep searching.
here is a super simple and affordable 2 way with Faital Pro 6FE200 and Selenium ST200 (in fact, any bullet tweeter would work)
6fe200 + ST200
you can even go MTM or TMM with the same drivers

Thanks! Already checked the post...
Sorry mi ignorance, but the build seems not very documented, and there is no FR nor impedances curves, no XO diagram, etc.
Anyways, I will check prices and availability for those drivers.
PA speakers with regular tweeters is really difficult, because the bass is so loud.
It can be done with heavy coned 8-10" around 91dB. I did this myself with an Eminence Alpha or Beta 8A and a loud 1.5" Audax tweeter and a regular second order filter in a cubic foot of reflex. It sounded very good. Usually 2mH/10uF bass. 3.3uF/0.3mH tweeter.
Marco_gea found a suitable 8" driver (and maybe something like that is made in Brazil. He used with a 91dB Monacor HT22/8 cone tweeter which goes for peanuts:

The 2Pi speaker uses a coil around 0.5mH on the very well behaved Eminence Alpha 10 and a loud Vifa DX25 with about 10uF cap and a 15R shunt. Bit Mickey Mouse, IMO, but who knows? Below. Hope that encourages you.
