Axiom Home Page Forums General Discussion Home Theater EP175 or Velodyne DEQ10-R?

I'm a little bit confused with all those sealed vs vented differences and technical terms I'm not used to. Concretely, what could be the noticeable difference between the Axiom EP175 and eD A3s-250 ? It may sound stupid and I know it is probably hard to compare these 2 sub but I'm planning on buying one of these 2 and I'm actually wandering if the EP175 is worth the 120$ more on final price including tax, shipping, customs...

Another thing I read in the link posted earlier is that vented sub a more efficient than sealed. Is that why eD goes with a 300W amplifier and Axiom is using a 175W amplifier? What I've been thinking behind that is if both speaker would sound similar, maybe I would get my money back paying more for the Axiom by saving on my electricity bill.

One last question... would both complete the M22 On-wall well knowing that I don't want a subwoofer that will shake everything in my apartment but one that will let me enjoy my music and movies the most?

Thank you for all your information, I really like to read the post and I feel that I have a lot to learn from you.

Doesn't enjoying music and movies mean shaking the walls?

I am not the foremost knowledge behind subs but yes i would believe a ported sub would be more efficient than a sealed as it would take less energy to move the speaker as their is less resistance. With that being said unless you are comparing the exact same amp watts are not all the same, there isn't much regarding the accuracy of what manufacturers claim their wattage to be. Please correct me if I am way off base

I wish I could answer the EP175 question for you, but I ordered one with a custom finish a week ago and it can take up to 5 weeks for delivery. I have the On-wall M22's and an on-wall/in-wall VP100. My room size is 1800 sq ft. I've heard that if your room is 2000 sq ft or less, then the EP175 should do nicely.

I just want something to complement the on-wall M22 and be small, because it will be positioned under the VP100. I'm not looking for maximum effect for movies at this time.

That is what I'm looking for too. I actually have a cheap 8" subwoofer with a 150W amplifier that came with a HT in a box and it is actually doing the job for the loudness but it doesn't sound really great. That is why I would like to upgrade to a better quality sub. I know that it is fun to make the wall shake but I live in an apartment, I had experience with loud neighbors before (the reason why I'm moving) and I would not want to be the loud one in my new apartment.

It is really hard to say which would be the better sub without listening to both of them.

For what you want, and considering where you are coming from, I would go with the ED.

Spend the $160 saved on more music to listen to.

The sub I had was the the PB 12nsd. It has a slight bump in FR around 50-60 and I felt it hit a little too hard for my tastes. The PB13 is noce and smooth but lacks the resonance Axiom subs have which I think makes them more musical. I only know this from A/B testing with mojo's EP600. If I hadn't heard them in the same room I am reasonably sure I wouldn't know they sound different.

It could also be that the PB12 produces a lot of harmonic distortion. That can also give a sub more punch. The PB13 has been verified to play very cleanly though.

According to the graphs on HTS the PB12-nsd is clean, just has that slight db increase at that most felt frequency and the PB13 U is a very smooth sub, the graphs look similar to a DSP sub, quite flat.
