Wilson Audio Haters

I own 2.5 way speakers which are very simple  to drive and I agree that full range speakers may go lower but are extremely difficult to drive, there is no shortage of LF at my listening room , Sometimes  I miss my sub once watching action movies but for music listening adding a sub to my system is absolutely unnecessary. 

itzhak1969,

What speakers do you have and what are the dimensions of your room?

Room Dimensions:10 ’ W x 13’ L x 9’ H.
Proac Studio 140 MKII speakers.

"Stealth Low Frecquency will become the new reference in low frequency."

The birth of another buzzword!

People don't understand what a subwoofer does, when you read the reactions overhere  it is stil clear that people have no idea.

Stealth Low frequency will always create a superior sound quality than any stereo system without it. 

Stealth Low Frequency showed;

- stage became wider and deeper
- instruments and voices becomes more tanbible.
- at very low volums you have a much deeper freq response.
- In the mid freq the sound becomes richer and shows more diversity
- the energy of instruments come more apparent of the loudspeakers.

When you play with a system with big speakers which can reach 20hz. You still need to play at high level to get this low. All the test with huge speakersystems showed that at very low volume level you missed the drive. 

Stealth Low Frequency also goes deep with even very low volume.

- new people who auditoned Stealth Low Frequency for the first time, often use the word Reference level. It goes so much further than what is possible with just loudspeakers. 

I have many stereo clients who never used a subwoofer for stereo use before. Just like me. When a subwoofer by S.A.P. and Stealth Low freqency is uses it creates a new level in integration but also in a higher level of the low frequency of the whole system.

The accuracy of Stealth Low Frequency makes it easy to use subwoofers till 120-140hz. This is also something people don't know. When you connect a subwoofer without S.A.P. you go to an inferior level of timing.

This is the level you all know. You all judge based on this information. Again this is audio 1980 thinking. 

The Pl-500 creates a stunning level in low frequency without a subwoofer. But when you bring in the subwoofer by S.A.P. the people their faces says it all. The level in sound quality goes to an even higher level.

They all understood after the demo how important the subwoofer becomes based on Stealth Low Freq. 

This only can be reached when you get the subwoofer in phase. And also the exact location were it has been put. Without roomcorrection a subwoofer is useless.

The roomcorrection systems use in subwoofer are able to limit the acoustic problems. But there is a huge but.......

It don't places it in phase and the right position. This is the level you all know. This level is in my world 100% unacceptable in result.

I understand the reactions. But they are based on the fact that you still think in 1980 knowledge and insight.
