About when will a 6.5 speaker in a door roll off?

[awdtalon21]

In a proper sealed door how low can you push a 6.5 door speaker? When will a 6.5 start to roll off? 80hz, 60hz? Just want to get your result from you guys testing speakers.

Thanks

I believe it depends on the model of speaker. Magnet strength, cone stiffness, fs, and others effect it.

Yes, you have midbass and midrange and the TS parameters of all out there.

And when you say roll off.. at what slope?

Too many variables.

Ok well I guess my problem is that my Hertz 1650.3 when running full rolloff at 90 hertz, my door is sealed good, but they won't play lower than 90 hertz, is the normal? that is what I'm trying to figure out.

Where is the filter set? They will play under that if the filter allows it

Crossover? I had them running full range when I checked with rew.

Are you saying there is absolutely nothing under 90hz?

It's normally to start getting a few DB of roll off. That's where the sun comes in to bridge the gap.

Run it full range. do a measurement with the mic directly in front of the speaker 6-8in. This will give you a measurement of what your speaker is actually playing and the effect that your enclosure is having.

Then when you record a measurement at your ear. Thats the effect that the reflections are having. I have some tm65s and they roll off rediculously early.

looks like a typical cross over reduction. check the cross over box and make sure you are running the mid on the widest band available and double check you amp and head unit so that they are set to 60hz hpf min.

most door speakers when installed in properly treated doors are capable of playing down to a minimum of 80hz i usually run mine down to 63hz. but the main contributor to the ability to play down in range is the hpf and then the install.

yes some speakers dont like playing down low but thats rarely the case

I'm sure that is a full range single, on the hpf side.

That's normally. That's why we use subwoofers for sub bass

So why then do people talk about crossing them at 63 hertz, I don't really like having to run my sub up to 80-90 hertz to match.

There is very little bass and it sounds pretty bad imo from my door speakers.
