I have a pair of DefTech BP7006 speakers, both with dead amplifiers for the powered subwoofers. But, I have a Rhythmik LV-12R sub, and I've been using the system (with an inexpensive Yamaha RX-V471) as a 2.1 setup (95% music, 5% movies). I don't really want to pay for replacement sub amps, because I have the LV-12R. Seems to me that if I wanted to improve the speakers, I'd just replace them entirely with something that better matched the LV-12R.
It actually sounds OK to my ear, although I'm a noob, and maybe it's actually terrible. I figured I'd ask the experts:
1. What's the best approach for optimizing this semi-broken setup? "Small" speaker setting, I assume, on the AVR? Where should I set the AVR crossover? I think I read somewhere that the BP7006s cross to their own subs at 120hz...so, cross there?
2. Maybe a question for another section, but should I run the YPAO program on the AVR? I've never done it.
3. Is this situation just generally a disaster, and should I just get new speakers? Or, are the BP7006s, when used as the worlds heaviest/largest bookshelf setup, still decent equipment compared to, say, $250-$500 alternatives (something like Elac B5/B6/F5, which I've had my eye on).
First, everyone hears and appreciates different sounds, so if it sounds good to you, it is right. May not be technically perfect, but you're the one listening, do don't stress right or wrong.
Next, e-mail DefTech, don't worry about the age of the speaker or if you're the original owner, if they have some NOS amps for those speakers they will help you.
1. Yes, AVR crossover, those are 4.5" divers so normally yes, 100-120Hz, but there are 4 of them, so experiment with lower, just choose what sounds best to you.
(Basic rule of thumb is to find the lowest point to where the speaker starts to break up or sound bad, and then set it 1 step higher)
2. You can try it if you like, but with a 2.1 setup, your ears should do the job just fine.
3. This is entirely up to you, but no, with a separate sub, it's not the end of the world, esp if you like the way they sound. You may be able to find something today sounds as good or better for that money, but again that's strictly up to you, the one thing that you will find is something that sounds different, esp considering that DefTech does have a signature sound and those are bi-poles, and they will image completely different from a mono-pole.
