Axiom Home Page Forums General Discussion Technical Questions EP 500

The sub primarily is for LFE (low frequency effects). That is why you set a crossover point so anything below that point for the other speakers gets sent to the sub. All the speakers have a different frequency range. 80hz is normally a good starting point, and meets THX recommendations. Some movies are better than others and will blow you away.

In regards to CD's, it really depends on the recording. The m60's do a great job in the bass category, but depending on the CD you have, there will be some LOW's coming from the sub. I have a few music DVD's that you can really hear the sub. One example is Diana Krall's Live in Paris or Live at the Montreal Jaxx Festival. The stand up bass just rocks my world.

Another issue could be your sub placement. Do you have a picture or drawing you could share with us of your setup?

Randy,
I tried your setting of -2db and 8 oclock on the sub volume and I wanted to know what did it read on your spl meter? From 15 feet away I read 93/94 on the spl. The pink noise was vibrating some glass cups in the kitchen.

I believe from my main seating position, I'm at about 80dB during the pink noise test with my sub. I'm also about 12-15ft away from the sub. Now I suppose the 3805 could be different than the 2805? Also, my room as not carpeting or furniture yet.....Hope to shop for carpeting this weekend..

Is that including the correction factor for the RatShack meter?

Hi all,

I just want to let you know that I call Axiom about the popping sound from the ep 500, I spoke to John and told him the story and he told me to do a test for the 500 by having the output of a cd player go direct to the input of the sub and increase the vol. a bit at a time and then came the popping at the 5 o'clock position.I did this test while I was on the phone with him so he can hear it for himself.

John at Axiom is going to send me a new amp for the 500 and I will replace it myself along with return shipping.

The guys at Axiom are the Best.

Thanks,

John Mincone

Wid, not sure I'm with ya when you talk about the correction of the RS meter? Please explain, anyting I can do to get the best sound would be cool. I've just heard people like running their sub dB's a little hotter, instead of putting everything at 75dB's or whatever....

Ain't it the truth! No product is without a problem every now and then. That's not a lot of comfort if you are the one that receives the unit with a problem. However, the true measure of the company is how the problem is handled.

While Axiom isn't the only manufacturer/vendor who has returned customer service to the importance it deserves, none do it better. After so many years of enduring poor service, it is a JOY to deal with companies like Axiom. And, their just reward is the customer loyalty and trust they have earned.

(My heavens, it's a beautiful morning here today. Cold, only 28, but bright sunshine and I can hear a few crazy birds chirping outside my window. I'm a happy man this morning. )

Randy, when using the receivers pink noise to calibrate the sub you should note that the RadioShack meter has a correction factor of +3 db. So if you use 75 db for your speakers and 80 for the sub then in fact the sub is being calibrated to 83db.

Thanks Wid, I was unaware of that, I used to tune everything to 75dB's, but lately have bumped up the sub to 80dB as I had heard some like to run the sub a little hotter.

When you calibrate everything to 75db, including the sub, you have the sub +3 db already when using pink noise generated by the receivers test tones. When I did my music system I used 72db on the meter for the sub. Then when I did my H/T system I went with everything at 75db.
