sir art anong ibig sabihin ng bandpass type & ano ung ibang type? best buy na b sya 4 P2500?
thanks.
That's a good price already, bro. Although, as I always suggest, tawaran mo pa. This is one of the very early powered subs from Daiichi. Great performance at its price. I sold one of my 10DRs to a friend and he just loves it. It's a very good sub for entry level set ups. Very versatile because of the wide frequency response range. Di ka naman magsisisi. Bandpass enclosures are those that have the driver inside the enclosure itself, there's a 4th order bandpass and a 6th order bandpass, this sub is a 4th order sub, having the one side of the driver sealed and the other ported. Isobaric, meaning the drivers are arranged facing each other and working in unison at opposite phases, "push-pull type" in layman's terms. 6th orders have both sides of the enclosure ported, like the Bose bass modules. The disadvantage of band pass enclosures are they tend to have inaccurate bass response, as the name implies, it allows only a certain "band" to "pass" through it, and muffles others, it tends to resonate a limited frequency range. The driver may be reproducing a certain frequency but the enclosure design translates it to the enclosure's resonant frequency. But this results to a very, very powerful sound. There are front firing types, some are sealed, some are ported. Front firing types are those that have the driver's front exposed to the listening environment. This seems to produce more accurate bass since the frequency reproduced by the driver itself is heard in the listening environment. Sealed types have a very tight sounding bass since the enclosure aids in the driver's cone movement, I think this is called acoustic suspension. These types have a very high power handling capacity, Ported types are more powerful sound than sealed types, on the assumption that they are driven by the same power, since the driver has more freedom to move and therefore results in a more powerful sound. But it's easy to blow drivers with this type of enclosure. This is just my little understanding of things, I'm not saying it's absolute. I think it would also be great if you did a little research on the web about speaker enclosures. Just trying to help, sorry kung medyo mahaba. Ingat.
