The Space Shuttle launch exhaust, approximately 3 miles per second, is said to be 215 decibels! This is louder than one ton of TNT. How they measure that, I don’t know, since the SATURN 5 ROCKETSHIP is said to melt “concrete and burns grass one mile away!” Some rough numbers for Saturn V after brief web search: SPL at source: 220 dB At 1000 yds.: 197 dB At 1 mile: 135 dB “at least a half-mile away lest you get inundated by 165-170 decibels of painful sound. Unlike many other loud noises, the shuttle rocket sound is constant as it creates the thrust necessary to lift it from the ground.” I know. Been there. I was on the overpass on I-95 when all the cars pulled over. So we stopped too. Just in time to see, hear and feel a shuttle launch vibrate and shake that concrete bridge as easily as a storm jiggles a tree – ten miles away.

Years ago, I compared the 20 and 25-Hz output levels for various price subs. I found used subs, kits, such as Parts Express (simple to assemble, saves a lot!) and DIY to be the most bang for the buck. Forum poster THE EAR suggested using epik, elemental designs and SVS.

nice equip, however... CDs have “musical” things happening below 40-Hz, no matter what the subject matter! Using the Real Time Analyzer in the Behringer DEQ2496 UltraCurve Pro, let me tell you, even the human voice has harmonics that extend below 40Hz. Rock/popular music certainly gets below 40-Hz, unless there is no kick drum, bass guitar or piano! 40-Hz is the low string on the bass guitar, which means there certainly are harmonics lower than the initial 40Hz note. The kick drum makes a 30Hz note and can reach momentary peaks of 120dB! That alone should indicate the deep for very big, very deep and very powerful sub-woofers to replicate music realistically.

small speakers are no comparison to large speakers, IF you have the room.

BTW, I do use a Behringer crossover to smooth out the peaks, love it, don't think it degrades the sound, think EQ makes most systems sound better for the money

Nonsense. EQ is NOT the only weapon of choice. In fact, most small to medium size room will need some form of acoustic treatments to deal with the energy sucking room modes. Khorns can be hot in the mid-range, it makes recordings seem harsh, something to do with the crossover. Crites has solutions, so does Al K (ALK). http://www.alkeng.com/klipsch

second that: LaScalas with a sub, Cornwalls wqith a sub, Khorns with a sub, beer with a sub!

I would never buy anything unless I liked their sound. The Advents have a very different sound than Klipsch. You might add a sub to them and use them as the mains; though finding matching surrounds will be hard. Bigger is better with speakers. I would rather have two great mains with a one or two very good subs than the special effects of bullets whizzing off to the side.

will land does your tag line have to so much detail? There is room for all that in your system description on your profile... I would look at assembying a Parts Express sub, awfully lot of sub for a few hours work...

The hybrid Big Ole Horn created by marrying the vented front driver woofer of the Cornwall with the large mid-range horn of the LaScala resolves two problems: The lack of deep bass (below 40-Hz) in both the Belles and the LaScala models The smaller soundstage, imaging, clarity and sharpness of the Cornwalls The Cornwalls, the Cornscalas probably have a tipped up mid-bass (80 to 100-Hz) common in many high end, full range speakers, just as the recent B&W Diamonds. This is nice for modern music and movies. Corner placement does get the Khorns out of the way, reducing their footprint to half the area a conventional floor standing speaker needs, but they are still big. Despite their awkward size and need for corner placement, the Khorns have deeper bass than many full-range speakers (30-Hz). This is wonderful for realistic, natural and orchestral music. But it is a smooth, flat and accurate deep frequency response often criticized as being too lean. I am a bass loving man. In addition to passive bi-amping of my 15 inch Khorn bass bins with a 48-pound solid-state amp, I also have a very deep bass sub-woofer with dual equalizers controls to add bass below 30-Hz. For movies, I simply dial up more sub.

nice!

Is it the tweeter or the mid horn? If you block the tweeter (try a sock), does the mid still sound too sharp? Is the room loud or shouty? Is it still too sharp when you sit at the sweet spot? Do you have isolation platfrom on the tube amp? On the CD player? Try these things, although it probably is the crossover...

sweet set up, good equipment, needs sub!

I do! Got my old PC refubished with new Seagate 1 TB HD backing up to my old 250GB, using it for data, my music is there, but it is only 80GB, not streaming to stereo...yet

the 15" driver in the Cornwalls is for efficient bass, but it is not deep bass, the mid-bass (80-100 Hz) is okay, there is a bump in that region, but even big Cornwalls need a high output, deep bass sub-woofer, think 15" Epic, Parts Express kit, etc. The ultra high sensitivity of the Cornwalls makes them perfect for tubes

I am...was Need fix on bass amp and new 2A3 tubes I think I lucked out. My power amp puts out 60-watts max. My mid and high end tube amp puts out 6-watts max. Turns out to be the correct ration for passive bi-amping. Stock AK2 crossover on Khorns is at 300-Hz. Seems to be low enough not to hear the difference between the two amps.

Speaker Tests

Me? I dream about bi-amping ALK's extreme crossover with my 2A3 SET or VRD tube amplifier on mid and top end, and either my Pioneer or Pass class A amplifier on bottom end. Can't go wrong with Macs.

I totally agree, the LaScalas with subs are still not Khorns. After AXPONA, again, I was worried about turning on my Khorns. Shouldn't be. They have faults. They need ALK crossovers, better mid and high-end horns, punchier mid-bass, deep bass sub, maybe even a colored scrim to make their semi-truck size fit into family sedan living rooms more easily, but the big ole horns still give wide, bright, ringing, clear, quick, dynamic and natural sound! Not as warm and cozy in the recording studio feel of many small cone systems, but effortlessly engaging for the price.

I interviewed many of the vendors for StereoList.com. The exhibitors introduced themselves and their equipment for StereoList.com. Listening to horns on horns can be wonderful. It is hard to capture the true, life like quality of the combination of horns and tubes, but this might give you a little taste of what high end audio shows are really like. Yes, people talk all the way through of the demonstrations, and the videos! The videos are linked to Audio Tube Amp, Big Ole Horns, and The Tweaking Audiophile fan pages at Facebook.

I heard Summits and recently heard Saunders Sound Systems at AXPONA. (See Deprecating the Gods article at EnjoyTheMusic.com.) I recently attended AXPONA again, the largest high-end audio show on the East Coast. I briefly interviewed about 50 different exhibitors about their sound systems for StereoList.com. The videos are linked to StereoList.com and the Audio Tube Amp, Big Ole Horns, and The Tweaking Audiophile fan pages at Facebook. The Khorn bass measures deep and flat – flatter than Cornwalls or probably Martine Logans. A lot of speakers intentionally bump up in the upper bass and treble. B&W 800 Diamonds do. Yet the Saunders electrostatics were wonderful sounding and only $16K!
