Kain Posted June 1, 2002 Share Posted June 1, 2002 I hear a lot of people saying that the Klipsch KLF-30s have a lot of "slam". But isn't the subwoofer meant to give you this "slam"? What exactly do you mean when you say "slam"? ------------------ Coming soon...

T2K Posted June 1, 2002 Share Posted June 1, 2002 "SLAM!" is the sound made by a door as your wife leaves the room after you've informed her that you're about to buy a new piece of audio equipment.

HornEd Posted June 1, 2002 Share Posted June 1, 2002 "SLAM" is what some people use to denote the force with which you hear and feel a sound, KAiN64. A kick drum, for example, comes across as a sharp sound on some speakers, but the KLF-30's move so much air that you can feel the SPL's in your chest... that's "SLAM". Consequently, the KLF-30 with its dual 12" woofers became a favorite speaker of the Rock and Roll crowd. -HornED Quote Link to comment Share on other sites More sharing options...

boa12 Posted June 1, 2002 Share Posted June 1, 2002 kain, the 30s will handle the 2nd octave (40-80hz) slam along w/ a great sub like the svs ultra or velo hgs-18. the sub in my book handles the 1st octave (20-40hz) pretty much by itself. but the sub & speaks like the klf-30 or rf-7 can work together for the ultimate combo of bass quantity & quality in the 2nd octave range. that's why i keep harping on the value of a flexible processor or receiver that let's one drop the crossover down from 80hz to something closer to the speakers true capabilities, like 50 or 40hz. allows for much better quality bass while retaining the same output levels, at least here it does. ------------------ My Home Systems Page Quote Link to comment Share on other sites More sharing options...
InventiveAudio.com Posted June 1, 2002 Share Posted June 1, 2002 Boa, I totally agree. I have a massive DYI 15" sub that is tight and deep but music sounds much better when I listen to my Cornwalls then my Heresys with the sub. I'm not talking about mids and highs. The Cornies make lots of bass that intergrate better with my sub. Perhaps if I had a variable crossover for the sub things would be different. Unfortunately, my crossover is static at 80hz. Too bad because I would love the ability for variable crossover settings. Quote Link to comment Share on other sites More sharing options...
boa12 Posted June 1, 2002 Share Posted June 1, 2002 trader, right on forgot to mention the cornwalls in the sys also benefit the sound greatly when cut down at 50hz w/ the same global crossover. since they're in the rear corners due to space, they bring up the rear for some real even room bass response. similar to having a rear sub or 2. i think it's a good idea to have bigger speaks &/or sub(s) in the rear for HT also (for 5-7 channel stereo music it's a given). mixers these days are puttin a lot of lower bass in the rear channels. the downside to the global adjustable crossover is that the centers are also there at 50hz. could overdrive my C7 going lower than their capability, but i've found the c7 go much lower than they're speced & seems most mixes these days are shying away from a lot of real low bass in the center channel. still wish i had the room for bigger center & rear center speaks. the adjustable cross is a nice tweak feature. hopefully my lobby influences more makers to include it in the future. denon's doing it now, though i don't understand why they only put sub-80hz selections on the 4802 & higher. just trying to keep the big speaks in ht revolution going. we need to be heard. ------------------ My Home Systems Page Quote Link to comment Share on other sites More sharing options...
HornEd Posted June 1, 2002 Share Posted June 1, 2002 KAiN64, "SLAM" applies to any kind of speaker that delivers a feeling of being hit or "slammed" in the chest... so if your sub(s) can deliver the "SLAM" fine and dandy! skonopa the KLF-30's earned their reputation long before your upscale system was born. The KLF-30 reference was purely historical. For example, when I bought six KLF-30's for my HT, the authorized Klipsch dealer marked me for a Rock 'n Roll fan... rather than an HT enthusiast. I still like my music best on the Heritages. -HornED Quote Link to comment Share on other sites More sharing options...
boa12 Posted June 1, 2002 Share Posted June 1, 2002 i advocate big slamming speakers AND a big slamming sub, crossed at the optimal point, for slam heaven. i want it all. ------------------ My Home Systems Page This message has been edited by boa12 on 06-01-2002 at 01:22 PM Quote Link to comment Share on other sites More sharing options...
TheEAR Posted June 1, 2002 Share Posted June 1, 2002 " "SLAM!" is the sound made by a door as your wife leaves the room after you've informed her that you're about to buy a new piece of audio equipment. " Now this is a grand slam To me speakers with slam are speakers that can really make you grasp for air when at high volumes you can feel the drums.And its not sub bass,sub bass is not slamm. Often reviewers say sub A or B has slam,this is the sub capability of extending from 40-80Hz.Slam is in the 40-100Hz region. Below 40Hz there is no such thing as slam,if I hear someone talk about 20Hz slam I slowly turn around and walk away.They are misguided and lost to the point of no return. For example the KLF30 and RF-7's have BIG NASTY slam,you will feel your internal organs being assaulted. TheEAR(s) Now theears Quote Link to comment Share on other sites More sharing options...
WMcD Posted June 1, 2002 Share Posted June 1, 2002 I agree that "slam" is a visceral effect. Symphonic Star Trek, Telarc, has some orchestral "slam" in the recording. The K-Horns do a good job on reproducting it. And some direct radiator bass units do a good job too, according to reports above. My guess is that reproduction requires good bass response through out the bass spectrum. And further, that a well damped bass system is necessary. On the last point, you hear poorly damped bass boxes which have a boomy sound which accentuates one note. I doubt they will do the job.

NOZ Posted June 1, 2002 Share Posted June 1, 2002 HornEd is right. I replaced my La Scalas with RF-7's, and with music the 7's don't even compare (sigh), but they are more accurate with HT. Luckily, I didn't sell my LAS, I' going to incorporate them into my new HT room.

NOZ Posted June 1, 2002 Share Posted June 1, 2002 It may sound strange, but the La scalas are throatier, you know that deep down grunt. I'm going to hook them up again and compare them,(I hate dragging 123lbs around), but better to do it now, than to screw around with it after I hardwire the HT. ------------------ NOZ SYSTEM Fronts: Klipsch RF-7's Center: Klipsch RC-7 Rears: Klipsch RS-7's TV: Toshiba 37" DVD: Toshiba SD 3107 Receiver: Harman Kardon AVR 7000 CD: Sony CDP CX250 EQ: Harmon Kardon EQ-8 Sub: Velodyne V-1012-B Spare/Back-Up: La Scalas Quote Link to comment Share on other sites More sharing options...
HornEd Posted June 4, 2002 Share Posted June 4, 2002 Once again, TheEar(s), I agree with you on the sub 40Hz being below the "SLAM" range and into the "grind you into jelly omnipresence." But many folks do have their crossovers set to where their subwoofers are extending up into the "SLAM" range. -HornED Quote Link to comment Share on other sites More sharing options...
boa12 Posted June 4, 2002 Share Posted June 4, 2002 ed, having the global adjustable down crossovers in the processor really makes me want the klf-hec for center(s). just wish i had more room oh well, before i move b&k will probably come out w/ an upgrade that allows high pass settings for each speaker or each speaker group at least. ------------------ My Home Systems Page Quote Link to comment Share on other sites More sharing options...
TheEAR Posted June 4, 2002 Share Posted June 4, 2002 HornEd, In fact,you are correct as most users subs are cut at 80Hz and a bit above.So they will have sub slam. A great slammin subwoofer is the RSW series,oh do these pack a punch.They dont compete with Sunfire,Velodyne,SVS,HSU or Revel for ultra low bass but the RSW's sure can punch like the best of them. This is why I will add the RSW15 to my RSW10! Its good to be the bass king. HornEd did you hear PMC speakers? I did this week and good lord these are accurate and AWESOME.Some of the best sound at ANY price!! I am now considering saving for a few good months and buying the large PMC MB12 monitors! I am in musical heaven,I need I need these speakers. Not cheap,12000/pair! WIth the large PMC MB12's the subwoofer is an option,almost true full range sound.
