PRECISION REGARDING TERMINALS FOR CREST AMP BARRIER STRIP
On post # 475 i showed a pic of two spade terminals making a "V" shape for barrier strip connection. This should be considered as an...

A USEFUL PIECE OF INFORMATION
I've been using Caig's Deoxit Fader F5 for years in order to clean static noise on pots for example. This with more or less success, depending on gear, since static...
Pierre,
RE And if i understand you say than 4 box 816 will be ok too ?
NO, you don't have the drivers to make 4 X 816 boxes. Only the 416-8C pair can go in the 816 cabinets. The GPA 416-8B...
Ok, lets make this simple for you.
Altec 816A and 817A/B are front horn loaded cabinets. To explain this simply think of some sort of a megaphone at the front of the box: the curved sides along...
Hi Karlanza,
Welcome to the Lansing Heritage. Here are some quick thoughts.
The Altec 416-8C is described as a 16" with 16"frame, while the GPA 416-8B is said to be a 15" but has a 16" frame...
CREST AUDIO AMP INSIDE PICTURES
As referred to previously, there ya go.
The 30-day seller warranty/return privilege has expired. The 19 y.o. amp (2003) works well and sounds good so i kept it....
Sorry for my misunderstanding, i do agree they should conform to specs, within the tolerances provided if any.
I was referring to old vs new since GPA is re-issueing former Altec models,...
Well, based on your experience and measurements then GPA woofers should be considered as new and different versions vs the originals. I haven't compared their TS parameters (older vs new) but i guess...
Have you given the drivers a "break in" period before measurements? New woofers do need a good workout before their parameters settlle to normal values.
"The stifness of surrounds and spiders may...
I checked the grey twisted pair installation cable i used to connect signals to the Crest Audio amp and counted 10 wire twists per foot so shouldn't be a problem. Easy to identify on this type of...
Sootshe,
Something didn't seem right to me with the numbers presented in post #5 and had another look. This is not to criticize your work, i found it a pretty clever try for someone who "never...
Hi Glenn,
Nice to hear from you, been a little while. I hope you are doing well.
The horns look great! Thanks for your good word, however you deserve the credit for this having done all the...
Since port length is increased a little it will tune the box a little lower. In order to keep the same box tuning frequency then you have to increase port area a little, which tunes higher, in order...
Alf,
The way i understand it, with horn/driver directly on top of cab, is that you may have a small natural angle upwards? In some situations might not be bad, if they were firing straight and...
Alf,
RE more isolated by resting on something like herbies fat dots as opposed to resting directly on the cabinet?
Not sure i understand your question correctly or what you're trying to...
CREST AUDIO AMP LISTENING TESTS
Since my last post here, i did a third listening session with the Crest amp. The comments cover all three.
This amp sounds really good. i was struck right at the...
Alfmonster,
Its a balance between two evils in my view. I agree with Riley's close together idea. But on the other hand raising the entire speaker system by putting it on a stand, will create some...
seetlee,
Well the protection capacitor frequency was higher than crossover frequency! This is very curious. Normally that cap freq is one octave BELOW crossover freq as indicated by JBL. You...
The Crest Audio PA-150 is my first Crest and Commercial series amp also. I figured if that's what it takes to get a good used Crest amp then i'm game. Would not have purchased one from many other...
Not exactly the same but it reminds me of the very tall, multiple drivers infinity system. Don't remember the model but a pic appears in Eargle's Loudspeaker Handbook.
Mike,
I have both Win ISD from linearteam.org and WinSpeakerz from trueaudio.com
Download free Win ISD latest edition (2016), you may want to avoid their prior editions, still available, but...
Hi Mike,
Quickly as i'm busy.
You're the second guy i see here not having too much faith in speaker box lite results. What you ask for is not that easy, and the fact nobody else replied...
