Help for a good speaker design!

[ZuMbAiU]

Hi everybody! I want to construct a 3-way speaker with this drivers:
Low`s - Eminence DELTA 12LF -??-500hZ info
Medium`s - Eminence Alpha 6` - 500-4000 hZ info
High `s - Eminence APT:80 or 130 ;it`s good?-4000-?????hZ info

I looking for any good design for good basses ,may be any standart design with schematics,because I have any attemp in the amp`s ,but in the speakers this is my first project

If you have no experience on speaker design, nor suitable measuring equipement, I suggest you take some predesigned system and build that. It's not that easy to create a good speaker by only knowing the drivers you want to use.

If you want a reasonably priced system with good bass you could build for ex. this:

Landroval thanks for your answer,but i like the futurious outside design like

this .
Or may be the classical speakers like this in the attached file. Any other ideas for this drivers configuration.For the making of the speaker i have the assistance of one very good woodworker

 

[Landroval]

Ok. Basically you can design the outside of the speakers to be whatever you want. The look of the drivers is the only thing limiting your creativity. Of cource it's important to keep the internal dimentions of box as designed, but that's rarely an obstacle for creativity.

Here's a list of some sites with good designs among wich you might find a few that pleases you:

Any Project concrete ,may be not with The 12LF ,but with any 12" driver and any medium`s,because I can`t select

OK for a PA system. Is that what you want?

 

[ZuMbAiU]

This is for my little partys -big rooms with 70-80 and many peoples and for a tech-house,tribal,jungle,minimal...
I look for any good design for optimal bass and dimensions and for optimal inside design of the speaker
I want a Professional Speakers and only this speakers because his life is very long and because the amp is a Quasy Mosfet with 2x310Watts RMS@8 oHms But this is my first speakers project and i need any help for the optimal choise🙁

I think Landroval is on the right track. If you determine the size and style of box, you can change the outside appearance to suit you.

I think you'll be fine going ahead with the all Eminence system but maybe even consider the APT 150 tweeter versus the 80. I like the dispersion better. Never been a fan of the short round horns.

You'll probably do OK with 400 and 4000 XO points, min 12dB. Are you planning passive or active?

Another choice is the drop it to 200 or 250 and double up on the mids for power handling. Geez now that I think about it, is there any reason you are not going with a 15" low end?

 

[ZuMbAiU]

Cal thanks for the fast answer.I think for many project ,but if it`s possible a 2 cameras speaker-1 for the low`s speaker,and one for the meduim`s and for the high,`s because this is my favourite sub design for all times:
Is this design is possible for the Eminence and effective?
If you can give me any link because the Dayton 3-ways project from Landroval is too good but I am affraid that i can confuse things🙄

 

[ZuMbAiU]

Cal I want to work for me with the
Dayton RS 3-way towers ,but can you help me with any little draught for my drivers and this cabinet,because I have a mortal fear when I think how I can make any big mistake,may be because you are a expert in the speakers 🙂

 

[Cal Weldon]

Thank you but I'm anything but an expert with speakers.

Do you want to build the Dayton tower now?

I'm not sure what you mean with the subwoofer. Do you want the Dayton towers and the sub?

 

[ZuMbAiU]

I want to build the Dayton Tower ,but with my speakers. I think that if i can mix the design of the sub with this of the tower will be great ,but this is may be very wicked.I want to build the Dayton Towers but I wait for any draught from you Cal-any dimensions or any info for this project any graphics....,because I can`t build this speakers only with 2 images from the link and many imagination
🙄

 

[ZuMbAiU]

Cal can you help me for the redesign of the tower because my idea for this speaker in the attachment is very stupid

 

[Landroval]

Uuhh. You should get the T/S-parameters of your drivers, and try to model the appropriate sizes for the compartments for your drivers. You cant just pick some size and build it because every driver is unique and needs a specified enclosure.

Edit:
I modelled the 12LF with WinISD. For best quality I would put it in a SBB4 70 liter reflex tuned to 50Hz (vent for ex 15cm diameter, 20cm long). The enclosure is quite small, so to easily get away with baffle-step issues I would buy an extra 12LF and make the bass section bipole (one driver front, one back, wired in phase).

The other option for the 12LF sacrifices a little quality but goes a little lower. This is QB3 120 liter reflex tuned to 44Hz (vent for ex 15cm diameter, 12cm long).

Get this:

Input the driver data and find a design that pleases you.

Guys I can pay now for this Peerless S315SWR3908 :

An externally hosted image should be here but it was not working when we last tested it.

iNFO
Datasheet
If this driver is the best choise for me and the beautifull bass ?
For the basses The Peerless or the Eminence?
I wait for Cal nad any info for me but the driver is much important theh the design now?
EDIT: The Peerless Magnet is too little for me may be

 

[Cal Weldon]

Please don't wait for me to answer. Being a mod means I can't be everywhere at once.

There are much smarter people to answer your questions than I. Landroval for example. You should follow his advise, download winISD and sort out what you want to do.

That peerless woofer looks too wimpy. You've now gone the other way from the Selenium. I wouldn't go any less than the Eminence.

 

[knifeinthesink]

Here Ya go.

Just the thing your looking for. Slightly different driver configuration but all the design work is done. There's even a forum so you can ask questions specific to these kits. Not to badly priced either. Not sure what you'd be in for shipping wise though.

 

[ZuMbAiU]

Thanks
kifeinthesink🙂
Cal in Bulgaria the monthly wages are may be 70 euros and the assortment for drivers is very minimal.I teleprone to all firm for audio ,but this is the assortment and the two candidates:
Eminence DELTA 12LF

An externally hosted image should be here but it was not working when we last tested it.

OR
The JBL GTO120 sub with 250 RMS
INFO

An externally hosted image should be here but it was not working when we last tested it.

I think and for the second because I dont know but in Bulgaria JBL is a big name.
In kifeinthesink the best design for the delta is bass reflex.Any good projects in this design in the our forum may be?
I want good basses from this project ,because in the tech music the bass is deficit and i want hear and feel her.
Thanks for the suggestions and we are invited for more info in the thread

 

[Landroval]

Dude, you could buy the drivers from abroad, there are many european online shops who deliver also to Bulgaria.

Ask these for instance:
