SWL Posted April 15, 2014 Share Posted April 15, 2014 I personally don't like how a flat response sounds. I like chest pounding wall moving bass. Right on reference head. I sleep with my eq. Gotta have it..... When I had RF-7's I had to get used to how clean and tight the bass was. It was there but didn't seem like it because I was used to bass that was much less sophisticated. Big amps, EQ and subwoofers and I was in heaven. OP....keep experimenting and you'll get there. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted April 15, 2014 Moderators Share Posted April 15, 2014 I also eq my cornwalls. As good as the cornwalls and rf7ii are they still need a little eq to make nice with the room and what I like. I personally don't like how a flat response sounds. The room makes a big difference, our Cornwalls in the bedroom have ridicules bass, if it were any more I would adjust it, but it's not a huge room 11x16 speakers on the long wall tight in the corners.

Heritage_Head Posted April 15, 2014 Share Posted April 15, 2014 (edited) Both my corns on a wall far away from corners. Probably would not need any eq if I had them in corners (for bass). My 7s are on concrete so they need a bump as well. Edited April 15, 2014 by reference_head 1 Quote Link to comment Share on other sites More sharing options...
Codyred Posted April 17, 2014 Author Share Posted April 17, 2014 Silly question. Do you have the RF-7IIs out from the wall so the rear firing port can do its job? Yes, I had them about1.5 feet from the wall. Quote Link to comment Share on other sites More sharing options...
babadono Posted April 17, 2014 Share Posted April 17, 2014 codyred, Ok good if i understand your response that is 18 inches, should be sufficient. So that is not the problem. Quote Link to comment Share on other sites More sharing options...

My RF7 II's were on carpet over concrete slab family room 11x18x8 on short wall with no placement options about 5 feet apart. How do you post a picture?

Heritage_Head Posted April 18, 2014 Share Posted April 18, 2014 Put a pic on photo bucket or something then copy the info from that. No idea why they made it way harder with the new forum. Seems like really old tech. Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted April 18, 2014 Share Posted April 18, 2014 Concrete can make it sound like zero bass if not set up just perfect. Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted April 18, 2014 Share Posted April 18, 2014 (edited) If your in any bass null it will be like you have no bass at all. In a normal room with normal floors even if your in a small null the speakers are still shaking the floors and everything on the floors. So you would still get some tactical feel and bass presence. On concrete the floor don't shake so unless your in a sweet spot it's going to be very weak bass. And if it's a big bass null it will sound like the bottom drivers are off.

Ski Bum Posted April 18, 2014 Share Posted April 18, 2014 My RF7 II's were on carpet over concrete slab family room 11x18x8 on short wall with no placement options about 5 feet apart. That's pretty close together to get proper sound stage width and scale, unless the primary listening position is near-field, which is probably not advisable for those speakers anyway. Getting them spaced wider, in closer proximity to the corners, will bring the bass up. While you're at it, don't be afraid to play with toe-in, perhaps to a more extreme degree than you have previously. Your speaker's directivity in the upper registers can be used to your advantage to sidestep early first reflections. Reducing that high freq reflected sound will help shift the tonal balance to the warmer side at the listening position. You may find it to result in better imaging/sound stage, too. Have a look at THIS for some ideas on how to get a stable image over a large area. Quote Link to comment Share on other sites More sharing options...
beeker Posted April 18, 2014 Share Posted April 18, 2014 after some time with my 7's and 7ii's i had no issues with low end power on an 85wpc hk receiver with no sub on carpeted concrete floor in a very close to the same size room you have. really sounds like you may have an issue with your networks or wiring. after you try different positioning of your cabinets and maybe push them with a larger amp out of curiosity i would certainly pull out a couple woofers and take a very close look. just take your time and tape or write down what wires go where and so on. with 50 watts on a descent amp even 30 watts(i used a rotel 30x2 on 7's and 7ii's for testing and was impressed by the natural low end output) they should do pretty darn good. A large amp on the other hand no sub needed imo although helps with some particular tracks or material 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted April 18, 2014 Share Posted April 18, 2014 (edited) Larry, I don't agree because the published frequency response curves don't back up what you're saying. All of the Reference loudspeakers are relatively flat and sometimes just a wee tipped up towards the end. These are bass reflex designs, so the majority of the low bass is coming from the ports in conjunction with any room gain. I wouldn't be surprised if the ports are taking over around 50Hz. Klipsch assumes that a sub or two will be in the mix. Flat response can sound a little thin and forward -- most people don't like it (hence things like EQ and subwoofers that are set to dominate the sonic signature). Those are close enough together that you might be dealing with an out of phase wave cancellation issue. http://upload.wikimedia.org/wikipedia/commons/2/2c/Two_sources_interference.gif Edited April 18, 2014 by DeanG Quote Link to comment Share on other sites More sharing options...

muda Posted April 19, 2014 Share Posted April 19, 2014 Adding subwoofer is a total pain specially if you expect perfect clear bass, may be your room is non symmetrical, then try relocate fronts.With subwoofer i leave front setting "large" in receiver, it keeps low to mids more natural in my RF series.In 80-s with 3 way speakers and even mid speakers had dome construction it was way easier to achieve quality.To get a speaker to work perfectly in 30-2000 hz range is a big ask.

Have a look at THIS for some ideas on how to get a stable image over a large area. Howdy, and try to keep working at what you have, until you are expended. First hit the THIS that *Ski Bum has posted for you to read, and move the speakers to as far apart as space permits. Then do the first toe-in towards you the listener X number of feet away from speaker. Then toe-in a bit further, while listening to same material/source. That null thing must be occuring somewhere, IMLO. Takes time so relax and reflect while reading these frontline posters. A process of elimination is in order, one at a time. 2 Quote Link to comment Share on other sites More sharing options...

philly0116 Posted April 19, 2014 Share Posted April 19, 2014 I've never owned a pair of RF-7ii's but a friend has. I witnessed first hand a picture about 10 feet away from the speaker fall off the wall when he put the screws to them. He was driving them with a Luxman M-4000. It seemed like there was enough compression in the room to crush an aluminum can. Not sure why you aren't getting that out of yours. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 20, 2014 Share Posted April 20, 2014 It seemed like there was enough compression in the room to crush an aluminum can LOL, good one. Someone here once said, " ... it knocked the snot out of me." I've always been grateful that I'm not a bass freak, because getting good bass is freaking expensive.
