BEYMA 6P200Nd and low qts speakers

Postby threeplumes » February 21st, 2022, 9:11 am

Hey guys ..... looking for some advice on the BEYMA 6P200Nd , first of all has anyone had any first hand experience using the speaker in a car door ? basically i am looking for the the perfect balance between loud and still conform with most of the sq fundamentals.... i am keeping the doors stock without mods.... now i have used alot of different 6's and most of them when proper eq is done can do well over 100hz - 120hz but what i cant seem to get is something that can go a little lower for proper sub integration aka i want more more mid bass while still using a pro audio speaker, now after looking at the specs it seems to be a good option it plays up to 8-9t hz, i am using silk domes so i need to to use a high highpass crossover point for them to play loud enough to keep up with the pro audio midrange ( I am willing to make a compromise on imaging ) .

My main questions is with regards to the Low QTs .29 , i am aware of the fact that for infinite baffle installs a qts of .5 or higher is what is needed for optimum performance in the midbass area ,if not the beyma anyone have real world experience with low qtc pro audio speakers in car door applications ??

Those speakers will work for sq.Important things to note.You will need to bandpass them.
Highpass at 50Hz.lowpass according to the tweeters, but not too low.

It's not just Qts, but the ratio of Fs/Qts that's important.

This driver however has only 5.5mm of Xmax. Should work ok for midbass duty (perhaps with a bit of EQ), but higher Xmax = louder midbass production without noticeable distortion. Something to consider if you're looking for the most output.

so considering that the fs of 56hz is alot lower than most other pro audio 6's which are mostly around 90-150 it should do ok in the door ....and i just did a check 5.5mm seem to be on the higher side with regards to pro audio midbass/midrange.

I have a pair of these which i tried in my doors when i was thinking along similar lines as you. They wont play the full definition of midbass by any means compared to a good true car audio midbass 6.5". Are they better than the other pro audio 6.5" that people use on their doors? IMO yes, better than any other that i have used or knowingly heard - they would play very much louder, handle more power and sound "cleaner" at high spl but if you think youre going to get magical midbass out of it, especially in a car door, just like any of those other pro audio 6.5", its a waste of good money. I took them out and went back to my component set.

yeah i kinda know i won't get component level mid bass at high spl levels but i willing to try them even if i could squeeze a 20hz more on the low end band , a solid 80hz with a sharp cross i happy

Well in that case you will be pleased. They are very well built as well and treated to handle the moisture in the doors.. an important factor to give it credit.
