Peerless buyout 4"

[yeldarb43]

I just got into speaker building. With one project behind me I can't wait to start the next one.

I was thinking of doing some surrounds with the Peerless buyout 4" driver and maybe the HI-VI buyout tweeter or the Dayton silkie or maybe the Dayton neo to really do it on the cheap. Really cheap projects would be great because I would love to make some as presents. Also what about using the HI-VI tweeter/mid assembly flanked by two 4" peerless as a center channel? Would any of these ideas work?

I would really like to cut my teeth building really affordable projects, but I don't have a clue how to design crossovers or boxes for that matter, and really low budget plansdon't seem to be around. How do I get started learning how to make my own. Economics is my chosen profession but I always did well in and enjoyed physics and math and so I think I can handle and enjoy the technical requirements.

Any recommendations for a crossover or where to get started are greatly appreciated. Thanks.

The 4" Peerless wouldn't need a mid since it's basically one already.

Pairing it with a Dayton neo would be a great project, crossed at 3KHz. Even a small MTM would be an option.

here is almost everyting you need. these programs make it easy. spend a couple weeks playing with them and you'll be designing your own in no time. it is far easier then developing general equilibrium models or determining granger causality to boot!

you will need ms excel and a good way to start is by scanning in the impedence and FR graphs PE has for most drivers

The easiest tool for modelling boxes is WinISD from <A HREF="http://www.linearteam.org">www.linearteam.org</A> (just get the "beta" version for starters).
If you get "XOverSim" from the above mentioned FRD Consortium, you can use PE's data (text) files. Just pick some drivers that they provide them for and come back with questions.
"SPLTrace" (also from FRDC) let's you generate your own frequency and impedance files for use with XOverSim, the only thing missing is phase data, and you don't need Excel to use WinISD, XOverSim, or SPLTrace.

Thanks guys I appreciate the help. I think I'll try to come up with something for a peerless/ dayton neo combination like pete suggested.

Lots of fun!

Brad

Phew... I was hoping for something more in line with Ricardian comparative advantage. Or maybe creating demand curves for Giffen goods... see "bose". Perhaps something easy like economies of scale...

You know what the use of equilibrium theory is... me either. Actualy I think general equilibrium goes a long way in making all the astrologers of the world look credible. No offense to Dennis Murphy, an economist i think, if he is a proponen of GE. Hey if Dennis can design some of the best crossovers then why not me right? LOL.

Thanks for the help.

Hi Brad, welcome! The FRD tools are great to start with, I've used them, along with the fantastic advice I get from this forum, and have successfully used them to design some of my own projects. I used Win ISD to come up with the cabinet for this sub, box volume and port dimensions. I'm still learning about crossovers, so I still stick with "Other Peoples Designs" for now. Jeff Bagby's XO program is also a great tool to help you with getting the right alignment. I would recommend Ray Alden's book, "Speaker Building 201". This is a terrific book to get started on the path to speaker-building addiction.
