Why do so many people modify Klipsch?

[Coytee]

I've seen these but never experienced them. One thing kind of unique about subs, at least the one I have, is that during scenes where it has a lot of activity, I can feel it blowing on me ten feet away. It's like "Did someone turn a fan on?" I believe it could blow a candle out 6 feet away. It is really moving the air. The vibrato gizzmo will vibrate the furniture. But it won't give you the air pressure you can feel on your drums, as though something actually exploded in the room. Even if one can't hear it, they can feel the sound pressure change in their ears.

(as I butt in on your conversation)

I agree with the sentiment of this comment.

Though not the same, I had an experience once. (I might add that I do not own a sub of any type at this point in time)

I went to Danley's place in Georgia with specific plans to hear/feel their DTS-10 however, they'd returned a couple days prior from some show and their showroom was wiped out. They were putting things back together and don't you know....of everything there.....the ONE thing they had yet put into working order was the DTS-10.

Be it as it may, they showed me several other things. one of them was the sub under the couch. (DTS 8??)

What ever the model number, I personally found its effect to be a bit strange because my music was playing "X" loud, my butt was vibrating at "X" level however, the REST of me was vibrating at "X-50%" level and it simply didn't add up in my brain.

I found it to be an out of balance experience and would rather forego any sub rather than what I experienced at that point in time.

They then decided to unleash their big subs on me. I don't know the number but these were some of their larger ones.

Wowza.... even the hair folicles on my arms were vibrating and THAT is what I was talking about :thmbsp:

The room was pressured, the hairs were vibrating, the lungs were being deprived of breath.... the whole package.

I'm glad I went through that experience as now I know the under the couch version will never work for me. I just need to tell the wife that I need two subs. Two of the larger versions :thmbsp:

The sub I have is this http://www.rythmikaudio.com/FV15HP.html in piano black with the silver cone (In my avatar). The thing weighs ~120lbs. and will go down to 14 Hz. You can see the size compared to the La Scala. It is nearly the same dimensions as the woofer section of the LaScala cabinet. It has a 200 oz magnet. That's 12.5 lbs. 600 Watts to that single driver.

I am extremely pleased with it. I've heard a lot of subs in my lifetime and was never really impressed enough to get one. But these newer models now available are a breed of their own. These aren't the rumble makers of yesteryear. They provide low articulate bass extension at SPL's that really create the sense of being there. It does not hurt the clean bass of the La Scala in any way I can tell. The transition is unnoticeable.

Has anyone used Volti Audio upgrades?

The horns by themselves look pretty nice, even the crossovers are well constructed but personally I'd rather use simple ALK designs and extreme them.

If you have the older Klipsch with the early crosssovers, they can't handle much power with the 6 and 12 db crossover rates. The Ev t-35 tweeter can only handle 10 watts continuos RMS. So to increase the power handling of its speakers Klipsch changed crossover rates to higher order, changed drivers, change crossovers again changed drivers again. So depending on which vintage klipsch you have and how loud you want to play them, you need to update them. Personnally I prefer the sound of the unitd from the early 70's before they iniated the steep rates on the tweeter mid cross over. The new in house tweeter don't impress me at all, but I think the mid is a big improvment over the Atlas driver they used early on.

I am still very happy with my older stock 1979 Klipsch Cornwalls....... the only reason I purchased Crites "Type B" new cross overs were my 30 plus year old oil filled "caps" in the cross overs might leak oil like my Revox R2R did. I have my Corns in a small den and 100 Db is clean and clear with a AVR(no jokes please). I have used tubes and different SS amps on them for 30 plus years and I have not hurt the any of the drivers etc. playing them loud.

Thanks hotroady,

Yes, for me its the first watt, that counts. And yes these amps express the contrasts between soft and loud with greater range not only on a whole but among individual performers and instruments. It is something to hear this as it makes the music more live or involving otherwise the sound is kind of homogenized and can put one to sleep as a friend told me when we were auditioning power supply mods, low DCR vs high DCR. I guess for me I like impact and these amplifiers are about this as well.


I would say your probably right on those Acoustic Suspended Subs.
Not an easy thing to do sometimes to integrate subs, a friend yrs back tried with ProAc Response Two's and ended up taking the sub back as we were perceiving kettle drum bass to far forward into the stage rather then to the far rear of the stage as the ProAc's defined the recording. The ProAc's BTW just had superior bass response in contrast to the very expensive sub at the time. But for $3000 the ProAc mini monitors should be good and they are.

Myself, I would rather spend the money on high end Inductors for greater frequency range of performance enhancement say 30-700hz on my Fortes then the 20-100hz with a sub. The 100hz to 700hz has a lot of low frequency information in it that IMO is just lost from my experience, There is body and impact to be had in this range that standard inductors make sound wimpy falsely leading people to believe that they need a sub. People often ask what subs I'm using especially people that have heard Forte's and I have to tell them I don't have any! and their response often is you got to be kidding? and then to tell them they are just listening to 10 watts usually results in expletives from them. Better yet are silent facial stirs, just priceless. But all this is my path certainly not everyone's cup of tea. But its been working for me.

I have always admired Martin Logan's great transparency.

Your project sounds pretty challenging with the ML woofers. I wish the best of luck with the project.



Cheers

Well..I gone and done it! First of all let me say I tried putting these monsters in my RB-75's, but no way. Let me say they don't take to mods at the Martin Logan forum, not even small ones. This is the 8in woofer w 4 in voice coil and huge caged magnet: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=295-610&FTR= This took a huge commitment, the hole had to be hogged out and pastic cut. It just fit the Martin Logan Clarity's..can't tell it's there until the cover taken off. I read a lot of threads before doing this. Bob Crite posted "a link" somewhere concerning heavy mags and large voice coils. The ML driver was an 5ohm and the new Dynavox is 8ohm. The 8ohm load being better for my Fisher X-1000 I'm driving the Clarity's with. I really like the size of these ML's The larger the 'stat, the more power you need to drive them...just the opposite of Klipsch. I'm working with 55 watts rms per channel tube power. I lost about a third of my throttle due to the huge resistance of the huge mags. The stock ML drivers always sounded thin..the main reason I always used a sub with them. The ML's are 2 ways with crossover@400hz. Impression? Holy Crap! Did I get lucky! I played a big band CD and the woman listening when I was done installling couldn't believe the sub was out of circuit. I agree with you in this case Set 12, so much tractor like torque with this set up in 45-400hz area. The voice's of female singers are just so present! I suggest that drivers be tried on all outputs, mine worked best on 8ohm speaker taps. Going from 5 to 8ohm drivers had a mini autoformer effect. I think the only thing to try now is a non iron core coil. I know this completely different than a set amp and high eff speakers, but I' m very thrilled what this did for bass response. I consider this my best set up, now! Haven't gotten to the Quadramatic yet, and the the four Amp ohm dry polyesters.

 

[SET12]

Sounds like you have it dialed in!

Its nice when one can have an evenness over a frequency range. Its the big failing of iron core inductors IMO especially little ones but even the larger Iron Core exhibit the unevenness I hear as well not to mention the real lack of body, now you have a taste of what I hear much like you describe from my Fortes

I have no doubt you'll like those amp ohm's :thmbsp:
