JBL and Infinity speakers from craigslist UPDATE..... (1 Viewer)

Ok. As some of yall know from my previous posts. i went to go check out the Infinity SM 152's and the JBL E90 speakers. I am reposting the ads and pics of both. I tried them out and i have to say the Infinitys sounded really good. I got home and hooked them up in the garage and they sound great. I still need to mess with them and make them sound as perfect as possible. Check out the pics. Any suggestions on how I can make them sound really good? They are running on an Onkyo HT-R540 (were running on my Sony HT but keeps giving me the protection error).

The JBL E-90's are in great condition. they look new and sound great. BUT I do have a question on them. I also attaching the ad and some pics. NOW I hooked them up to my living room setup which sounds badazz. The E90's come with four connections just like my polks in the gameroom. two red and black on the top and two red and black on the bottom. (the polk audio TSi400's i have the speaker wire connected only on the top two red and black connections then running to the AVR and works awesome (i will attach pic also). I noticed on the E90's that when I put the speaker wire on the top two red and black connections it sound loud. you can hear the high and mid levels really good BUT not the lower levels. Meaning the two 8in speakers on the E90's barely move at all during songs i played like black widow, dark horse and other bass songs. Not sure why??

So I went ahead and took the speaker wire off the top two connections and moved it to the bottom two. Now the sound from the E90's sound really low and the 8 inchers are really thumping.......BUT the mid and high are barely heard......actually the center speaker is where the vocal are coming from and is not loud enough. what am i doing wrong? do I need to connect all four? If so, how?

The living room setup (pic attached) is running on an Onkyo HT-R590, Polk center cs10, two subs one Onkyo 10in down firing and a cerwin vega 10 in down firing, the two E90's and Onkyo surrounds. What can I do to make the E90s give me the high, mid, and lows? I know there are a lot of questions on both sets of speakers......but thank you in advance. Anyway I ended up talking the guy down to $80 for the Infinity's and 190 for the JBL setup (which included the E90's, JBL AVR, 5 Klipsh speakers, 5 JBL speakers and the subwoofer (8in) for $190. Not bad at all for all of this. I think so?

my living room setup with the E90's. and my garage with the Infinity's. and my gameroom setup.

what can i do about the middle part of the woofer on the infinitys.....the middle part seems to leaving a lot of dust. what can put on it or what can be done (pic attached)?

Vacuum the cone with a dust buster and brush.

Yes, you need to connect all four.


The purpose of the dual sets of binding posts is to allow for bi-amping. As you discovered, one set of posts feeds the mids and highs, while the other set of posts feeds the woofers.


Normally, if you are not bi-amping, there are metal plates that are attached between each pair of red and black posts to connect them electrically. You feed one pair of posts with your speaker wire, and both the mids/highs and the woofer are active.


If you are missing the metal plates, then a short section of speaker wire to bridge the two red and the two black posts together will do the trick.


One more note on bi-amping: it is pointless to do with an AVR - don't even bother with it until you go full separates which would allow you to have a dedicated amp for the woofers and a separate amp for the mids/highs.

nice. thx.

Well I went ahead and took care of my JBL's. I got some plugs from BB. A friend at BB actually took off the brass bracket of some Klipsch speakers and gave it to me. Got home and put the brackets on the JBL's and hooked them up with some new plugs and BAMMMMMM. Good as new. Put on some songs like Black widow, dark horse, bass boosted songs and they sound bad azzzzzzzzzzzzz. Then I tried them with the phantom menace, revenge of the sith, rambo, and avatar. Wow. I am very happy with my new purchases........speaking of which.

I fine tuned my Infinity's in the garage. We had a BBQ tonight and all I can say is WWWOOoWW!! Along with my Onkyo sub they sound awesome. Very happy overall with my new sets. thx for all the help ya'll gave me.

I do have a final question.......My living room AVR is an Onkyo HTR-590. I was going through the settings after I setup the JBL's. ON this AVR there is no way of setting the XO's on every individual speaker. It just has one option for XO so I set it at 80. ideas?

What other speakers are connected for surround duty?

I got two Onkyo satellites for rear duty. and 2 Onkyo bookshelves for surround. not sure of the model numbers.? Would 80 in general be good?

Yes. I doubt the Onkyo go much under 100, but 80 works anyway...in this situation.

If your AVR has "direct", try it a few times on 5.1 and 7.1 content.
