I'll bet that if you tried the Spectrum RTA (it's free with NO PRO or paid versions) app you'd like it as long as you have a decent phone mic and replacing a mic in a phone or better yet a tablet, could make it a nice packaged set up that would be used just for speaker set up. It has no...

It seems like every time I go to set it up there's some volume control that's missing in Windows or there's an incorrect setting in REW and I spend my evening reading through tons of posts for nothing. That's why I searched for an easier method to basically just check where I'm at when I start...

Unplugged my sub 15 years ago and never missed it even with AV Speakers. Then made my own speakers from parts of other speakers and was able to put together a dual amp 2 way system that played 24Hz to 24KHz at reference level. Deviation was nearly ruler flat with corrections at 3 points. They...

I hate using REW! So many things like this constantly creating issues, having to reset it up each time to do a quick pass is a pain. Plus it ends up with a flat line as the result. I've found only 1 app that works if you have a good microphone in you're phone, I compared a bunch of phone mics...

There have been studies done that confirm that there is a loss of DAMPING that relates directly to wire gauge and length. QSC has a chart that shows the wire run vs the gauge and how it affects the damping by loss in %. Damping however is not going to change the highest tones at all since its...

Just looked at some used DCA 1812 amps, 120wpc x 8 @ 8 ohms, 8 TOSLINK inputs and 8 block terminals, no other inputs. Guy wanted $140 for both in Glendale AZ. I dodnt test them passed due to input connections.

Because of their name, they have made it difficult to gind lut much about their stuff without seeing a million results that dont apply. I know theyre not an amp thats made for traditional amp use in that they were originally made for top of the line phone conferencing. Since that field has...

The only thing wrong with that is using a digital active crossover on a speaker like that will uncover all the inherent problems with that type of crossover. Having myself attempted using a number of digital crossover/equalizer DSPs, I found they all have many issues that you'll never consider...

Way back in the 1990s Orion was already making amps that were ½Ω stable. As it is now 1Ω is a typical mono amp rating. They do this because you can buy subwoofers in any load you want, even dual 1Ω voice coils. Getting the most from each piece is not limited to how well it tests on a bench...

My woofers were crossed @ 800Hz and the electrostatic panels had a natural roll off at around 660Hz I overlapped them from 680-800Hz. The woofers I used were 12" infinity Kappa 7s and Monitor Audio 10" both tested nearly flat up to 3kHz. @ 3kHz they had a huge spike then nothing after that. I...

I have to disagree, for obvious reasons, I myself have found a 2-way to be the best design and best overall sound balance. But like everything this is only possible when the correct drivers are used and how they are used. I don't agree with many "rules" for designing speakers since there are no...

Like DSP? They're top of my snake oil list.

My list of things has become quite a chore since last week I had a fire at my home, it melted everything, covered it in black soot and then the firemen came through soaked it all in water, knocked out the ceiling and tore out all insulation then covered it all with another generous supply of...

I'm playing retired by refusing to work for anyone have 2 more years before I can call it official!

I wonder how much amplifier damping has on ports? First thing I thought when Harbeths entered the discussion was the fact that the amps powering them would most likely be of a higher quality just based on experience of owners. Once you enter into the Polk range of speakers, there could be a...

TY! I knew I was probably incorrect since it was told to me by name and I probably only saw it printed a few times. I was an air balance apprentice for 1 year before I went back to sheet metal which I already had 2 years under my belt and there was much more work available. It was nice to see...

Has anything been done yet? I hate reading posts that just end without any conclusion or telling if anything was even tested. Im glad it was less than the usual 10 pages before finding it was dropped. My own testing has shown me that most suggestions that include a mini DSP are not the ones you...

I did Air Balancing on AC units in big buildings, we used specialized equipment to get readings of air flow through various sized and shaped ductwork. Of course each size and shape move air in a different pattern. We had to take several measurements in round pipe using a peto-tube (Im not sure...

Posting any tests would be redundant. Setting up my system is as easy as leaving everything flat since I made my speakers to reproduce a very close to flat output as possible. It did take me a few years of testing to accomplish this but in the long run I have found no more use to do any testing...

I agree, before you can expect to feel the sound, the recording has to have that included with it. My speakers can put out some room jarring sound. I once unplugged a ¼" plug while the volume was at normal listening levels and the resulting pop scared me but not the noise it made but rather by...
