Corrections and Updates
This page is for any blunders we have possibly made over the years. Our purpose of this page is to correct any mistakes that we may have inadvertently made while attempting to provide relevant information. Without correcting our mistakes the information provided becomes no longer relevant. We are sorry to have to create such a page, but mistakes do happen. Any confusion caused by us, we sincerely apologize for.
With that being said, here are the mistakes and corrections to go along with them. We anticipate few updates to be needed here, however if and when they occur they will be found on this page.
- In the book that we recommend on Amazon titled “Customize Your Home Theater 5.1 channel to 15.2 and everything in between,” it is suggested as one possible option to use a speaker selector switch (This can be found in chapter 25). While there is nothing wrong with using them, the mistake came in stating that “a speaker selector switch does not contain any amplification to increase the power to what is attached to it.” As it turns out it is able to handle the load of multiple speakers in use at the same time without causing an overload which would make the receiver power down for safety. Perhaps at high volumes and many pairs of speakers attached to it and in use simultaneously this could possibly be an issue. Having retested by running 3 pairs of main speakers at the same time for many months now at reasonably loud volumes for both movies and especially music, it is safe to say that using a speaker selector switch is an excellent option.
- Page formatting for this same book is not at it’s best. This is found right away when one simply skims over the index. Here the margins could be better. Another example in the book is the diagram information. Fortunately that was quickly fixed with them being posted online. Over time they have been moved to this site from another.
- In chapter 23 of the same book, there is yet another lesson to be learned. The chapter is titled “Sound test and what you can learn from it.” The other reason for the difference in sound discussed in this chapter is this; the receiver used to test both pair of speakers was simply not powerful enough to really drive the larger pair of speakers. Those super huge speakers needed an 8 ohm receiver. After many months of testing after the book was published it was determined that even if the receiver was turned up to twice its normal test volume the bass was not there. Adding a 14 band EQ did help some, but not enough. It did however dramatically improve a pair of traditional 12’s and they ended up sounding great! For these super huge speakers to have the full range of sound, it was discovered that using a 8 ohm 140 watt per channel pre-amp did the trick nicely and at low volume even! For almost everyone this lesson will be a non issue. The speakers that failed to get full range of sound with a 135 watt per channel 6 ohm receiver and the addition of the EQ are not speakers that anyone is likely to have laying around to use since they were dual 12’s (each cabinet had two twelve inch woofers in them).
- In the book “Customize Your Home Theater…” It was stated that the equalizer (EQ) will only effect the left and right sound coming out of the main speakers when listening to music. This part is true, however it also said that you could not run the EQ while trying to watch a movie in surround sound, which is not true. It was recently discovered that when running sound out of a device such as a streaming device or dvd player and into an EQ that you can still run surround sound thru your receiver. The EQ of course will still only effect the sound to the left and right speaker. As a result your left and right speakers will sound awesome, however since everything is running as analog instead of digital all of the other speakers will not sound as good as they should. The reason it is analog is because the only connections (input and output) on a equalizer are RCA connections. Because of this you would not actually want to do this (use an equalizer for movies), but you could.
- It took years to make this mistake and about another year to recognize it was a mistake, but here it is posted as promised. We wrote in several blog postings in 2016 (possibly early 2017 too) about how 7.1 channel surround sound replaced 6.1 channel surround sound and that was not entirely true. Yes, receiver manufacturers did stop production of 6.1 channel receivers (we got that part right). Where we went wrong was in failing to recognize for a really long time that a 7.1 channel receiver could be run as a 6.1 channel. This was quite dumb of us to miss this key point, especially since we knew you could still use it in 5.1 channel surround sound. So you see 6.1 was not really replaced since it does exist as an option to use on a 7.1 channel receiver.
- In 2017 we failed to act upon the obvious signs that we needed to change suppliers of products offered on our site. Due to or laziness we had to close down our store and start over with a new supplier. This time we did it the right way by deciding to never again be limited by just one supplier. Our store was down for part of June before re-opening again. We now have 2 suppliers and only have over a hundred products now. We learned the importance of having multiple suppliers and acting on tell tale signs right away in the future.
