Well, God bless you audiophiles! I have recently become addicted to great sounding audio and building with wood so I have just built some speakers (for home theatre and listening to music) My setup is like so: I have 2x - .71 cu ft. monitor speakers with 6.5" visaton woofers and goldwood piezo tweeters. They sound good being driven by a Crown XLS1000 amplifier.
Here's where I'm stuck. Based on reading all of these positive reviews on parts-express.com for the 15" Dayton Audio Classic Subwoofer for $89 I decided to build a custom box like others have with positive results and bought the sub. I tried hooking up the sub to my crownXLS1000 once I had the sub all screwed into the enclosure (8.26cu ft. with 2x -4" ports tuned to 21hz) and it just isn't performing! I tried everything I can think of to get this puppy working! I thought for sure it was a damaged woofer and parts express sent me several different subs because we both figured the sub was damaged during shipping causing the cone to sieze up. So the speaker will play and will get loud but it's not putting out any "bass" and shaking walls like all the reviews are saying it should with only 100 watts. I give it like 350 watts (amp turned all the way up) and then it starts shaking some stuff in my room but sounds horrible and distorts on the loud bass notes and drum hits. I don't know what's going on here. I tried every possible angle (wiring connections, different channels on amp, different subs). Here are some reviews on parts express which have me believing this sub should be absolutely pounding and shaking down the house at lower level.
"In a 7 cubic foot box tuned to 20hz the excursion peak above the tuning frequency is at about 32hz. You can give it about 125 watts before it exceeds its rated Xmax. With 250 watts input the driver is at about 12mm which SHOULD be within safe limits of the driver but that is just a stab in the dark. I ran mine free air at 20hz and it looks to do more then 1" peak to peak but I ran out of amp power (100 watts) before I could get the driver to bottom!!!"
"I just picked up 4 more of these on the daily special sale.Nice woofers, the first ones I had gotten and broke in at 20hz in free air.Boy do these jump! I would say a inch+ peak to peak.This is likely out of the voice coils xmax range but the raw excursion is there.
I have two 9.2 cf enclosures tuned to 19hz.f3@ 19.25 hz(winisd alpha). Im working on 4 more,considered isobaric arrangement.I plan to run the buttkicker home amp.(I believe Dayton underates wattage, or is one of the only companies with honest power ratings)I think they could handle 250 watts all day long. My daughter was impressed that she could feel her clothes shake at the distance she was from the speakers. Hits very low,smoothly on notes without boominess.Good value!"

When I ran this sub on the Crown XLS 1000 "free air" it is not moving or getting even close to 1" peak to peak at 100 watts. I have to crank it to like 350 on my amp before it even gets close and then it starts distorting. This is the fourth sub parts express has sent me so I just can't believe it is the sub. It will play music just not sounding like it should I believe from all the other reviews. Also the amp I believe is putting out recommended wattage because hooked up to my other monitors they are acting like they should. Am I missing something here? Anyone know what's going on and why my sub isn't acting the way it should?
Thanks for any and all help!
