How should I wire my 1500 watt speakers?

[AndrewT]

Hi,
send the two punk over to Scotland, I'll Email my address privately. Even though they're a bit older now, I'm older as well.

If looks are what Punkrok wants, then you have achieved that.

Does it meet his chest pounding Brief?

[tinitus]

All he needs pr side is this JBL 15" in BR (big?), and a mid/high horn driver, and then Punk will do it with class

Ok, I've been working on something BIG for the past fews days and I've finally got a schematic of it which I'm gonna post here when I can get my scanner to work.

I can write a page with all the details but I'll keep to the basics.

just over 9 feet tall

speakers: (bottom to top)
15" Titanic MkIII sub in 11 cu.ft box tuned to 17 Htz

2 18" Dayton PF460-8 Cast Frame Drivers each in their own 9 cu.ft. boxes with two 4 inch ports

15" Titanic MkIII sub in 2.5 cu.ft. sealed box

2 10" 10PW3-SLF midranges

4 Constant Directivity Horn Tweeters arranged with two dispersing vertically and two dispersing horizontally

The whole cabinet is gonna be dampened with 1-1/2" Acoustic Foam and Acoustic stuf polyfill foam for the midranges/tweeters.

As for power supply I plan to use a Behringer crossover ( http://www.partsexpress.com/pe/pshow...48-664&scqty=2 ) with a sub out and quad amp the whole thing with Behringer reference amps
( http://www.partsexpress.com/pe/pshow...number=248-749 )
for the tweeters and midranges, Behringer Europower 1500 amps for the woofers and Behringer Europower 2500 amps for the subwoofers.

Unless,of course , if anyone has any better and cheaper solutions.

I'll give you that... each enclosure would be twice the size of my refrigerator (edit - no, nearly three times, dunno how you'll get it through the door, punkr...)

Wha??? Why 4 tweeters? Why 3 different subs with 4 drivers?

Unless,of course , if anyone has any better and cheaper solutions.

Look a few posts earlier! Some of the best DIY speaker people in the world have put together your dream speaker! As another said, this is getting really old.

But I might build that speaker in post 96! (edit - what was I thinking? The wife would kill me!!! ) Wonderful work guys!

Guy's, I've been following this thread for some time. I think punkrokr is missing a valid point about drivers and there relation to there capability to produce SPL.

punkrokr- that design in post #96 is OVERKILL. Not only is that a lot of speaker, but I would redesign the plan to better fit my needs(thats me). You don't need much to produce excessive sound pressure levels.

From what I gather, you want a speaker system to give the OMFG effect and to be very loud(concert levels?), in that case for the home, 1 tweeter and one midrange per cab will do. Anything more, by the time you are at age 30, you'll need hearing aids. Post 96 will give the OMFG effect.

The pro drivers you are looking at a pretty good drivers, but you don't need many, there is a thread were some one took a pair of pro Eminence 15's and built a killer speaker system. In fact I have a friend in Ohio that did just that, when he turned the volume on his stereo up to 1/4 way, no one in the house could here any one speak.

IMHO, the stuff your looking at is just too much and could give poor results. One soft dome tweeter, at a close proximity does have the capability to damage your hearing. I do a lot on lurking here and have learned a great deal things about building speakers. In fact my view of design has change and I'm very great full for it.

Listen to the people here on what they say, you will learn a thing or two. Good luck punkrokr...

[AndrewT]

My mistake.
I gave Punkrok the credit (intelligence) for beginning to read and learn.

I have now discovered he can do neither.

I'm off.

Know what, I'd take a Tangband 3" fullrange setup over that lot!

It will sound truly and I mean TRULY aweful and it'll look like turtle head. A real dogs dinner IMO.

Listen to folks who have been building speakers for years and know what makes for a good sound. What you just proposed is an abomination. You'll need at least a 4-way crossover to make it work and preferably 5-way if you want to cut down on lobing issues from using 4 tweets. I can also see mid treble integration problems from tying to match those dispertion patterns. The bass is just a plain old mess, mixing sealed and ported, 15's and 18's and multiple tuning points...

I can't believe you've ignored the advice of some really knowledgable folks in this thread. Be realistic, you live at home and there's no way your parents or your room will stand to a design like that. There's also the small problem of getting it sound better than the integrated speaker on a Bush TV.

Waste of time and money.

[RobWells]

Yep there's been some great suggestions in this thread and he comes up with that mess of drivers

You can lead a horse to water....

[tinitus]

Well Punk...seems you have finally managed to provoke a collective collaps...

So here is my final....

4 x 12".....midrangehorn.....ONE HF horn above 10kz

HF horn ?

Cost of drivers pr side would be about 150USD, crossover wont cost much either
