TommyK Posted June 19, 2010 Report Share Posted June 19, 2010 Ive read that most prefab. enclosures are tuned high. Now my sister has an (dont laugh) 8" bazooka tube in her car and it is able to hit all the frequencies pretty damn good, but the lows, like the low lowwwwws sound unbelievable for that size sub, clean and rather loud. So I imagine that the sub is playing below tuning frequency when it hits those notes. How far is a sub able to actually play below tuning frequency and still sound that damn good?

Lowroll Posted June 19, 2010 Report Share Posted June 19, 2010 "Good" is a relative term. What sounds good to you might not sound good to me & the other way around. I know my truck sounds terrible below about 30hz, it peaks at 39. It probably all depends on the setup and the car its in.

TommyK Posted June 19, 2010 Author Report Share Posted June 19, 2010 "Good" is a relative term. What sounds good to you might not sound good to me & the other way around. I had a feeling someone was going to say something like that. Well can you still play like say 5 hz below tuning frequency and still retain sound quality that low?

I had a feeling someone was going to say something like that. Well can you still play like say 5 hz below tuning frequency and still retain sound quality that low? yes as a matter of fact you could tune 10 hertz below tunning and still sound good. it all depends on the set up, give a try and see what sounds best to you but i wouldn't go any lower than 10 Hz lower.

When you say "you could tune 10 hertz below" do you mean, "you could play 10 hertz below"? yes, for example if your box is tunned to 33 Hz you can set your amp to 23 Hz but like i said before every system is different just like everyones ear, so just tweak a little here and there until things sound good to you.

wL<3bass Posted June 19, 2010 Report Share Posted June 19, 2010 My old enclosure was tuned at 38hz I could play very easily into the mids 20s loud and without overexcrusion and without a subsonic filter... I was also running a larger then recommended enclosure size aswell as running over 1.5 time the rms power rating.

TommyK Posted June 19, 2010 Author Report Share Posted June 19, 2010 For some reason I thought that you couldnt really play anything below tuning frequency lol. But thanks for clearing that up for me guys. I dont have a system yet, nor care even, but I plan on getting one very soon as well as a system. Btw im loving this forum, the amount of information on here is incredible! Im stil reading lots and gaining information on car audio.

Im stil reading lots and gaining information on car audio. It's not that you can't play below the tuned frequency, just that the speaker will not be as efficient below the tuned frequency. The speaker will likely need to work a lot harder to reproduce frequencies below the tuned frequency so you should be careful to not cause the speaker to bottom out. The vehicle acoustics can also play a large part in the way it sounds as well. Quote Link to comment Share on other sites More sharing options...
