Just out of curiosity on a ported sub where are you setting your crossover frequency, 60, 80 or ... ?

Good question on the crossover - I was wondering something similar: My surrounds/rears only get down to 140hz. I notice the ED sub ratings only go up to 100Hz... am I going to notice a "hole"?
With my current "crappy" sub I have the fronts set to crossover at 80 and the rears/back set to crossover at 140...

I assumed they could go higher, I just saw that the specs only list 100hz as the top. A2-300 is listed as 18-100hz, as an example.

Why would you think you would experience a hole?

Speakers cover down to 150hz, subs stats show it covering up to 100... Seemed like an obvious question - I'm still a newbie to audio stuff so I guess I was just asking if it would be noticeable or not.
I assumed the sub could produce sounds of higher frequencies, I just don't know how high or how well.

Hey guys, just wanted to stop in and say hi. I have officially joined the eD sub community! I picked up a 2 year old a5-350 from a local guy last week for $325! It's the older downfiring version with the lt/350 amp and the 16o.v2 driver. So far I really like it.

Just been reading through this thread and there is a TON of information. I'm looking forward to learning more.

I just built an a7S-650 and sub doesn't seem to go low. I have the gain set at 12:00 and cannot get a the spl meter to hardly budge at a 16 and 20 hz reading...but on my hsu 3.3, I get a nice spl reading at 16 and 20 and the gain is set around 9:30...any ideas what is going on? HELP

Iam also running a pair of mbm's.

Sealed subs typically require eq to reach down to below 20hz . What are you using to tailor the response?

Iam running test tones from hsu disk and looking at my radio shack meter. Iam not doing something right. my 3.3 right now is outperforming this sub. I can crank up the volum and getting some decent spl but when I did that and ran a scene from wow, it sounded like it bottomed out.

Same location? Make sure they are in the same location and you need to run a measurement of the response. Is this the kit with amp?

yes MK, its the kit. I cannot believe I can bottom this thing out but cannot bottom out the 3.3. Just can't figure out what is going on.


I did measure from the exact location. Same corner (evcen treid different corners with both subs...same result...cannot get the spl meter to budge from 20 and below, and thats with volume turned up on the lt1300 amp, but the amp from the hsu is only at 9:30, and get some nice spl at 16 and 20.

Someone from the ed forum suggested check my wiring...at first I thought for sure it was right, but after looking at the diagram, for whatever reason, I may have put the positive leads on from the amp to the negative terminals on the driver...would I still get sound if done this way?

I gotta wait till I get home to check it out. I can't believe I did this, but I think I may of...!

Hey gang, forgive me if this is a dumb question, but I have to ask because this is killing me. I recently purchased an A5-350 and love the sub, but I want it to be more "active" when listening to TV music, video games, and movies. As is right now, I only hear it when the deep bass hits or loud effects happen. I know some may prefer this and I also understand that this is most often the desired effect, however, I would like to be able to hear the sub more often. Any ideas? I am running it at 80hz from my Onkyo TX-NR906, the crossover on the amp is turned all the way up and the gain is at 12 o'clock. I've tried playing with settings on the receiver, but haven't found the sweet spot. Tried the bass crawl and from what I can tell, it's in the best spot in my basement. Any ideas? If this is the wrong forum, please let me know the best place to post. Thanks!

I understand completely what you mean. My dual A5s hit very hard during a movie, but on music from my ipod, they still hit very hard, just not the same way. You might have a null also in certain frequencies in your room. I played test tones and used my spl meter to get a idea which frequencies I had trouble with. around 60hz is where I drop just a tad. If you get close to your sub during music passages, does it hit hard? It should be. Mine both do, thats why I say it has alot to do with your room acoustics.

Thanks for the advice. I'm running over to Radio Shack at lunch and hoping to pick up an SPL meter. I'm sure I have some funky room acoustics, it's a huge basement (25x25). What can be done to rectify the null if that is the problem? I have very little experience tuning a sub, usually just go by ear. Would love to have a fellow AVS'er near me help me out!

Check your levels first, and if needed an inexpensive equalizer can be a great addition.

get you some test tones to play just through your sub. 10hz-100hz. I have some that go in 1hz increments. Placement or bass traps can correct it. Im not worrying about mine. lol

fuhoser - your room is over 5000 cu ft and your sub is 15" with 500 watts. Try a 2nd sub and then you'll get what you are looking for.

I know, maybe down the road that will happen. I know I can get better sound in my current room though. I heard a friends set-up who has a very open area, larger than mine and the sub (much smaller than mine) was definitely more prevalent than mine was. I have been reading about some Audyssey calibrations to try and some adjustments to make, but right now a second A5-350 is out of the question. I do have another 12" ported sub just sitting around, but it's not matched so I am reluctant to put that sub into play.

Are you running Audyssey? If not, I would suggest running it. It will do its best to give you the flattest response it can for your room dynamics. It should also level match all your speakers.

I typically run my subs 7 or 8db louder than the rest of my speakers as I think it just sounds better. So after Audyssey runs, I increase the level on the Avr for my subs by that amount (after verifying the level settings with my spl meter).

If you aren't pleased with that result, I would graph your FR response as Nzeff had suggested. This will tell you what is going on. IMO, the 'detail' slam type bass for subs is around 40-50hz and up or so. If your curve below 40hz is a lot higher than the above 40hz, this could explain your perceived loss of 'loudness' for music, etc. To correct, moving your sub or integrating your other sub into the mix may help significantly.

This is where the endless tweaking starts to occur to try and achieve a 'flat' response to give you the most accurate (detailed) reproduction of the sub channel.

Thanks dominguez. I have run Audyssey before, but I always end up adjusting it because I feel it makes my speakers sound dull and flat. Will try playing with REW and an SPL. Sorry to hijack this thread. If anyone has any other advice, feel free to contact me via email. fuhoser@yahoo.com.

Update: Bought the SPL from Radio Shack and my settings were way off. Going to re-run the Audyssey tonight, but my speaker levels were 81-84Hz for my LCR's. Sub was at 90 something. Going to turn down the gain and try setting up the second sub and run the play with the REW software before and after the tweaks.
