ooohh! those are nice. if youre going to glue the broken part see if youcan add something to strengthen it as well.

Poly Woofer?
Sorry about the accident. You could leave the covers off play at low volume and watch the foam. Or just wait to refoam. The changed drivers should have no sonic aberrations. When I got my 4Bs there was a serious lack of bass. The woofers had been wired out of phase within each speaker. I was ecstatic when I got that straightened out. Still waiting to hear your opinion on these. Be safe have fun. Oh and get that freaking plant off the 5B (and not on the 4B either.) JK

How should these be wired? I played them at low volumes and there is a definate lack in bass compared to the 5B's. Seems to me from something more than bad foam. Mine has a solid red wire going to the positive on the top woofer, a red w/black stripe going to the bottom woofer, and a black connecting the 2 negatives. Does this sound right?
The speakers are fully protected from the plants. They are always taken out of the room to be watered and spend the day draining before replacing them. There's also always a catch tray just in case of leakage.

I found an older post in which Ugornot explains how the Infinity Dual woofers should be wired. Both top woofers were correct but the - from the top went to the - on the bottom woofer. Should of been to the + on the bottom, then the red-blk stripe wire from - to the - on the crossover.
I swapped the wires around on both and now I have plenty of tight accurate bass.
I can't turn them up too much until I get them refoamed, but I like what I hear. :thmbsp:
Foam should be here by Wed or Thurs.

Hey Rod; Glad to hear you got the wires straightened out. You diagnosed that correctly. I thought for sure it was the crumbling surrounds that had them so bass shy. I'll have to check them out once you get them re-surrounded.

Hey Brian, Even with the weakened surrounds, I can tell there going to give the 5B's a run for their money. You heard them this morning and could tell right away there was no bass, especially after I switched over to the 5B's.
New surrounds should be installed by next weekend.

Yes they certainly did have bass problems this morning. I thought the bass (or lack of it) was on par with a minimus 7. Thankfully you got that problem figured out.

Sorry for getting back so late. Glad an old post could help you out. Yes two woogers out of phase in the same speaker do sound bass shy. Its also not as easy to diagnose as speakers with a single woofer. In that case if you stand in the sweet spot no bass, but move in front of either speakers and have normal bass. I don't understand how this happens. But it could be why there are some deals out there on the 4/4Bs. Re-foam enjoy. And I was JK (just kidding) about the plants.

P.S. you could also do the battery test and make sure they both travel in the same direction.

Your explanation was perfect and easy to understand. I'm listening to them at a low level now and they sound great even needing a refoam.
The wife and I have an understanding about our hobbies. She loves plants and wants to have them in front of the windows in the LR to soak up the days sunshine where the speakers are set up. She doesn't give me a hard time about my gear and she gets to put her plants on them with precautions of course.

I was able to spend a few hours listening to the RS 4's tonight. Played a variety from Jeff Beck & B-52's to Aerosmith, Skynard and Floyd along with some blues and jazz.
Crisp clean mids and highs, tight accurate bass. Never boomy and sloppy. Imaging and soundstage is better than the 5B's. The speakers seem to disappear while listening in the sweet spot. One thing that I did notice is if your listening to a recording of a lesser quality, thats what they'll reproduce.
Overall I'm very impressed with the 4's and think they'll be with me for a long time.

Very interesting reading earlier posts about woofer wiring. I just refoamed my RSIIIb's and was a little confused when reinstalling the drivers. There wasnt any real problem because the wires were "color coded". It seems as though the woofers were designed to be wired out of phase as there was a positive lead wire connected to the bottom woofer's positive terminal. A negative lead wire was connected to the positive terminal of the top woofer. Both upper and lower driver's negative terminals shared a simple common wire. The bass seems fast tight and stong, even out of phase.
I had a bit of a problem because I found a set of four surrounds really cheap...the caveat was they measured too large on the outside perimeter and kept centering off-center. I should have trimmed the surrounds down with some scissors.:yes:

You should always get foams that fit your speaker without modifying esp. if its a standard size. I speak from experience :yes:

Think of the woogers as batteries. For batteries to work in series you connect + to -. So you have a wire come in on a positive of one woofer you then hook the negative to the positive of the next woofer, and then the negative goes to negative. so wire into + out on - wire to + out on -. It doesn't matter top or bottom. just the order. The only other way to hook them up is parallel. In which case it would be + to + and - to -. If the woogers are crossed over for different frequencies probably only the - is hooked together. Now after the mud settles I hope that is clearer. It should look like one of these.
+ _ + ______positive wire
|< |< parallel
- _ - _______negative wire
positive wire ____+\_/ - _____ + \_/ - ________ negative wire series
The IIIBs are series at least mine are. My marvelous graphics skill may need some clarification. the \_/ are the speakers in the series illustration. However the |< are the speakers for the parallel illustration. This is the correct way to wire series and parallel anything.
The easiest test is to hook a small battery to the the woofers where the positive comes in and the negative goes out. The woofers both move in the same direction they are in phase. If they move in different directions they are out of phase. Manufacturers may go out of phase between tweeters and mids or woofers, but never will dual woofers (that I am familiar with) be out of phase in the same enclosure.

No that is a way of wiring them in series out of phase. Unless something really weird happened like a voice coil in wired wrong. they are in series the way you diagram but out of phase. Once again I urge you to use a battery to check phasing. That will be the final test of phasing. If they are out of phase you will be amazed at the bass you get. Trust me that this is not the normal infinity wiring. But as I said weird things can happen use a battery. If the woofers are out of phase the air more or less cancels itself. You may even risk damage from over excursion. That said I am only talking about dual woofers in the same enclosure. Any other Tweet or mid may be wired out of phase due to crossover effects. I'm sure if you are getting solid bass yours are wired correctly but try the battery test. If wired incorrectly you are in for another experience.
Seems like I remeber my wiring as red pos purple between the speaks and black/ red stripe neg.

Before I reinstalled the drivers I did do a battery test because each drivers positive terminal had different color wires. Both cones pushed outward as they should when correct polarity is indicated. Like I said I'd never seen speakers wired like this but I had to wire back as was original to this pair. I'm listening to them at rather loud volume and I dont notice much cone excursion and while the bass is warm, low and pretty fast, the low frequencies seem to match up with the mids/highs and dont in anyway over-assert themselves....I've read that Infinity has been known to incorporate some unusual techniques for tweaking the low frequencies.
I'm a little color blind so that blue wire might be purple.
