HiVi B4N 4" Aluminum Midbass Round Frame
i want to build a box for two hifi b4n and one vifa 1" tweeter what size should i make it and crossover need i to use
I just completed a project with the B4N woofers and different HiVi tweeters. My box enclosure was 15.25 h x 10w x 7d outside dimensions with 3/4" material. I ported the system with a 1.5" port tube 3.4" long. I'm very pleased with the result.

What size disconnects should I use with these?
As a rule, I solder all speaker connections and restrain wiring with tie-wraps to the speaker frames. This not only eliminates the need for lugs, but mainly for troubleshooting; knowing the speakers are soldered, a failure [no sound] is likely something else [on the outside]. This goes especially for HT ceiling and wall installations.If you must use lugs, industry standard is 1/4" spade-lug. Some are smaller, 3/16" and recently I have been seeing 1/8" terminals on some import speakers. Buy a bag of each [mates, slip-on crimp or solder lugs] and you'll be covered for all your DIY speaker projects.

Will this work?
Greeting, I have been looking around the site for several weeks and enjoy what I see. I have a few questions about a JamBoxx I am Building. I have plenty of woodworking skills so my basis are covered there, I just need help on the electronics end.Here is my plan.This unit will be for use in my garage while I am working. I am not looking for max volume etc, just a great clean sound at low volume, at minimal pricing.The size of the box will be 20 inches wide by 10 inches deep and 10 inches tall.The amp I am using is theLepai Digital 2x15W Mini Amplifierwith Remote USB MP3 SD FM (Lepai Digital 2x15W Amplifier with Remote USB MP3 SD FM 310-302)The speakers (2) I was considering are theseHiVi B4N 4" Aluminum Midbass Round Frame(HiVi B4N 4" Aluminum Midbass Round Frame 297-429)And I will be using the MP3 output of the amp to play music from my Galaxy S2.Here are my questions.1. Are these speakers gonna work in this box?2. Do I need to port the box or seal it?3. I have tried many of the online speaker box calculators, but cant figure out how to use them, is there a very simple one?4. Are the speakers I have chosen enough, or do I need to add tweeters?5. How hard would it be to add something that would allow me to pick up AM radio (so I can listen to the ballgames)? And what would you suggest?
This speaker is not nearly enough for a box that size. The box is far too large for this speaker. I would suggest looking at plans for the "overnight sensations" here on parts express. I would use a tweeter if you decide to use it though.

hi. can someone help me with speaker box design i volume.?
EBP for this driver would be about 88, which would make it suitable for either a sealed or vented box. in a sealed box of about 5 liters, f3 would be around 76 Hz with a total system Q of .717 (very good). in a vented box of around 8 liters, the f3 would be about 42 Hz with a 1" X 3" port (tuning of 47 Hz). personally, I would lean toward a sealed enclosure -- you'll lose a little in efficiency (and bass extension), but the system will have greater power handling and less distortion at higher power levels, generally. good luck!!

I noticed the manufactures response graph and the Parts express graph differ. Which one is a better example to follow.
They are both accurate although measuring configurations may be different. It appears Hi-Vi uses a bit more smoothing to their graph which will make it look different. I would use our graph for design purposes personally.

would this driver hold up in a sheltered outdoor application?
Yes this would be find in an outdoor environment.
