Rog is a Good Friend of mine! As a matter of fact,
Rog was the first person to really explain to me, how bass
horns and the right woofer (TS Parameters) works hand
and hand. A next man I have to credit to is Weoggo Reed,
Ihoan (Designer of Bassmaxx) and, Bill Fitz _ _ _ _ ?

I've been friends with Rog before he put up that site.


If you look closely, most of those boxes are designed with
Precision Devices Speakers in mind.

If you have access to those speakers, build the PD 1850
Horn!

I can't imagine why you need to build one bass horn, but,
you seemed determined, so the most I can tell you is to
give it a shot!

If it doesn't give you the sound you want, just build another
one.

To be honest,

I've never heard of that speaker before, and, have no clue
what the TS Parameters are.

If you're going to build a 15 horn, maybe you should try
the HD 15. Providing that free speaker meets the horns
requirements


If its a unknown driver, (No TS Parameters) the only thing
I can recomend is throwing it in a sealed box.

I Just want to say one thing........ If you are under budget
constraints, maybe you should hold off on building a bass
horn.

Buiding bass horns are not exactly a walk in the park
(So to speak) You will spend alot of time, and
money on this project.

Magnet weight: 850oz
Voice Coil: 2.5"
Max.Power: 350W
Frequency Response: 30-3.5KHz
Sensitivity(1W/1M): 93dB

This is what i know about this driver ...
I don't know .. HD15 look very fine to me .. and not very expensive ..
Do you think that i should build that ?

Hmm ... i know that the box of a speaker is the most important .. that's way i want to make it good ..
What about this Ts ?? What is that ?
The HD1850 with that driver could sound like crap , what about the HD15 ?
I have experience in building cabinet's .. but i don't have in design ...
I don't want such a low freq. bin .. just one with a firm kick ... i inted to use it in live application in romania ( over 100 people ) outside .. so .. what do you think is the best ... i all ready have 2 bin's ( 4 driver's ) multirange .. and 2 bass tube's ( like the car one's ) and i can't get the sound i want .. not enoth bass/mid i guess ... and not enoth power ...

Thank's !!!!!!!

Dude, don't take this the wrong way...................


If you are not going to invest in the right tools
to get the job done right, you should just scrap the idea.


Either build the HD 15, or PD 1850 with the speakers
Rog recomended on the site, or don't build it at all. As
far as I remember, he offered alternative speakers that
will work in either cabinet. They may not be as efficent
as the Precision Devices, but they will get the job done.

You mean to tell me you can't buy any one of the
alternative speakers he recomended?

The speaker you want to use will not do the job in
those boxes. You'll end up wasting your time and
money, and be highly upset in the long run. Buy the
right speakers, or use those "Free Speakers" and build
a Double Fifteen box.

Period.


Again, don't take this the wrong way. I'm just being
to the point about things.



Remember,

There Are No Shortcuts In Audio.


Oh!

The TS Parameters are tools that helps you determine
what kind of box the speaker will give an optimum
response.

For example; Fs, Re, Qes, Qms, Qts, Xmax, and so forth.
Beside each one of those abriviations, should be numbers.

Surely, you used a speaker design program when you
built those other speakers right?


Best Regards,

About the tool's .. i have all the tool's you can imagine ... from a driller to osciloscoope's , about the wood .. i get it for free ....

Yes , someone calculate my last speaker , they have about 104 dB and 36 Hz . As my amp's .. most of them are build by me .. for the horn's ( if i gonna build them ) i'll use a 2 x 800 W , useing 24 output transistor's ...

If i gonna find the right driver's i think i'll build the HD15 .. it's smaller ...
What speaker software do you recomand me ?

Hmm...

What about that box with 2 driver's ( 15" ) that you mention ?
It's a simple cabinet design ?

If i gonna put an Eminence Kappa 15LF in the PD1850 horn will sound good ? He dosn't mention alternative drivers... ( name's .. only some specs about the driver i should use )

From a PD15 Horn with Eminence Kappa 15LF and a W bin with the same driver what you will chose ? I'am telling you that because in this morning i visit a friend that haved 4 x Wbin's and it sound great .. all the room shakeing ... he gave me the plan .. it's a ordinary plan from the net .......
