What speakers are you planning on doing this parallel wiring? The room layout suggestions from Dolby and DTS all have single points of sound. Also, going from 8 ohms on a receiver channel to 4 ohms will sometimes cause problems. I had to start using external amps when I switched to 4 ohm...

Reviewers don't always have the same goals as you do when it comes to subs. SVS subs get almost all positive reviews and have for years so I expected to like them. I used a pair of their Plus series 12" drivers and cloned a pair of older CS+ cylinder subs. They sounded great but they did not...

I equate quality to accurate reproduction of the input signal which means flat response with low distortion. You can get quality drivers and amps for in-wall subs that give you low distortion. But will they play as low as the input signal? Do you like action movies and want to feel the...

The phase isn't part of the level matching, it's part of the distance setting. Or better yet, delay. If your right speaker is closer to the mic than the left speaker, the auto calibration will add the proper delay. On an old Kenwood, I had to convert feet to milliseconds. Of the 5 speakers...

Projector Central has a mount distance tool for each projector they sell. I used this tool to properly set up my main seats. My wife sat in the seat and I measured the distance to her face. Yes, I had her hold a tape measure to her face while I measured. She thought I was a nut case until...

I've never used a multi-zone system, only read up on them so I could decide if I wanted to install one. I decided against it. So I have no idea if those controls can wear out. I think your idea of a speaker selector with impedance matching is a good alternative. Or swapping out controllers...

They explain the process on their site. https://www.tvguardian.com/which-tvguardian-is-right-for-you/over-the-air-antenna/ You must have a digital converter box to use it.

The Cen Tech from HF is fine for this. If your 8 ohm speaker has a crossover, then there is the possibility that 10 ohms is correct. You are reading DC voltage resistance. Your 8 ohm speakers are AC voltage impedance rated. This is very helpful. It is not surprising that you blew a couple...

With the sub disconnected from the receiver and power, gently press the cone in. You should not hear anything. If the voice coil has unwound, then you will hear metal wires scraping against the metal top plate of the magnet structure.

Disconnect the wires from your receiver and measure there. That's where it is important. If it is only you, get some alligator clips for your meter or even tape the wires to the test probes and record the values using your smart phone in video mode. Run around and turn up/turn down the volume...

What kind of volume knob are they using? For example, this one has impedance correction - https://www.monoprice.com/product?p_id=8242&gclid=EAIaIQobChMI_4f2t_783gIVBglpCh3QxQuyEAQYASABEgLln_D_BwE Have you measured the resistance without an amp connected? Have someone turn the volume knobs...

That will get you close since you put it in the loudest location but you don't know how flat the frequency response of your sub is. I had a 14db peak at 55hz which caused my sub to sound extremely weak during movies. If I turned it up for explosions on action movies, music was extremely boomy...

Thanks for the amplification information Chris. I'm running the http://projectgallery.parts-express.com/speaker-projects/the-d-iii/ as my left/center/right speaker. My Pioneer receiver could push them until a fast transient sound hit like a gunshot and the receiver's protection circuit would...

1. When properly calibrated, there is no such thing as overkill, there is only headroom which keeps distortion lower. I'm upgrading from dual 15's to quad 15's and if there is room, I'm throwing in a 21 as well. 2. What are your goals? I had a pair of SVS 12" Plus drivers and built my own...

Have you measured your sub's in-room response to see exactly what frequencies are causing the boom? You may need a DSP to tame some room induced peaks. I built my subs and they were weak when watching movies. No low end at all. When I turned them up for the low end, they were boomy to the...
