rafabond Posted January 25, 2015 Share Posted January 25, 2015 (edited) what do you think my configuration: the RF-82 II front have them in small position in the AV and subwoofer, JBL ES 250 PW, cut 80rz. if the front had them in Large and cut to 80 on the subwoofer, would I get better sound? What do you recommend me? AV is a Pioneer VSX-924. Thanks and I'm apologizing for my English Edited January 25, 2015 by rafabond Quote Link to comment Share on other sites More sharing options...
CHASLS2 Posted January 25, 2015 Share Posted January 25, 2015 Always small with a sub. Quote Link to comment Share on other sites More sharing options...
wvu80 Posted January 25, 2015 Share Posted January 25, 2015 (edited) Welcome, Rafa. Your English is fine. You have done a good job with your cross over (XO) points. Crossing to the sub at 80hz is a standard most people use. If you set your RF-82's to Large and use a sub, you will get a little more bass. You will get DIFFERENT sound, not necessarily BETTER sound. There is no standard that everybody does, it is personal preference. I think with the RF-82's at full you will get a more even bass across your room. Your experience in YOUR house should decide how to set your XO, whatever sounds best to YOUR ears. I have done it both ways, and I prefer to set my L/R speakers to "Small" and let the sub do all the low frequencies. My sub crosses over at 80hz, my L/C/R speakers are at 60hz. This gives me the clearest sound. Edited January 25, 2015 by wvu80 Quote Link to comment Share on other sites More sharing options...

wvu80 Posted January 25, 2015 Share Posted January 25, 2015 Dave, Did you see the WVU BB game? If not, you missed a thriller. It was not broadcast in my area, but I listened to it. WVU did everything they could to lose it, but somehow won. +++ Rafa, we return to you control of your thread. Quote Link to comment Share on other sites More sharing options...

rafabond Posted January 25, 2015 Author Share Posted January 25, 2015 I tested ..... if I put small in RF-82II and cut to 80hz, the sound is more earthquake. Large if I put the bass are not powerful. in exchange for music, you better put on RF-82II in Large and disconnect the subwoofer. What do you think?

derrickdj1 Posted January 25, 2015 Share Posted January 25, 2015 (edited) For music I run my RF 7's off the avr set to small and let the sub/s handle the bass. A good sub can produce deeper, lower bass than most towers, including the RF 7 and other Reference speakers. Also, this reduces intermodulation distortion and results in a cleaner sound. Subs are powered by a separate amp which leaves more power from the avr for the midrange. Edited January 26, 2015 by derrickdj1 Quote Link to comment Share on other sites More sharing options...
robbiey60 Posted January 25, 2015 Share Posted January 25, 2015 If you have a good power amp the rf82iis can slam hard frequencies 60hz-35ish hz while run full range. Anything 35hz and below a decent sub will be needed. It is then up to you and your eqipment if the sub should cover the higher frequencies.

derrickdj1 Posted January 25, 2015 Share Posted January 25, 2015 (edited) The Reference line is not strong in the 35 Hz region. The distortion goes up dramatically if were are talking about a typical listening position and not a measurement from 1meter anecohic. 95 +% of all towers, not just Klipsch can benefit from a sub. The key point is will the difference in distortion be audible. That depends on listening habits, room, and volume. The increase modulation distortion is based on science.

I can have my onkyo at +6 (master volume) and bass at +6 (tone control) before I can hear any distortion, that's not to say it isn't happening. Obviously it is too loud for comfortable listening but those 4 8" woofers slam! For a long time I ran no sub and the subs I did purchase couldn't or struggled to keep up, until I found some proper subs.

derrickdj1 Posted January 26, 2015 Share Posted January 26, 2015 Many people take pride in their tower speakers which is OK. The point I always try to make is that there is more speaker cone breakup with speakers set to Large. Using a good sub convert the 2 way Reference system to a 3 way system. The other main point is the sub can be placed where it works best which is harder to do with the mains. Since a lot of rooms are small, the distace to the wall is less a factor in clean sound with rear ported speakers. The extra head room in the avr allows for less chance of clipping the amp and damaging a speaker. The advantages of the small setting are to great to ignore for me.

It is nice to know that if I want to crank just the speakers they perform rather well on their own, but have nothing compared to the subs.

Sancho Panza Posted January 27, 2015 Share Posted January 27, 2015 The advantage of setting ALL my speakers to LARGE: Sounds Much Better, is too great for me to ignore... But, this is not for everyone; try it both ways for a week, or 10 days. 3 Quote Link to comment Share on other sites More sharing options...
