I'm about to have a new setup for a while when I finish my Advent studio monitor conversions. I'm going to have this setup in a seperate room hooked up for people to listen to music in my other room.
It's a decent receiver I got for free, decent meaning it makes anything from Bose or Logitech ever made sound like garbage.
This is the stock speaker, my Kenwood bookshelves. Their tweeters sound pretty good. They are basically Panasonic paper tweeters, much better than any Mylar tweeters ever made.
I'll be swapping my BX5a drivers in them until I build my iPod dock with them. They sound a good deal better than the stock kenwood drivers, and the tweeters are good enough to keep up. If the crossover was better, it would sound just as good as the stock BX5A's.
I decided to try to use this amp on the left channel with trebble on minimum and bass full from my center out on my computer from a cord I ripped out of $5 headphones and it works. From 40 watts RMS from a stereo 70's receiver, I'm getting more bass than most 12 inch subs can deliver from $200 or less subs.
Anyway, to my standards, it sounds like crap, so does anyone have any reccomendations for a powerful sub amp? I'm thinking of just getting:
I'll just keep using it till my driver dies, and when it does, I'll pop in an LMS ultra 5400 and use that until the box I build for the 5400 is built, then I'll have my sub setup finally done.
Any thoughts on how my Velodyne ULD 18 would sound amplified by this? How would it compare to say, a Maelstorm 18 inch sub, which gets about 2.4% THD @ 110 decibels, 20Hz?
I don't know enough about audio yet to predict how it will make my velodyne sound, but with less than 1% THD, and taking into account that my Velodyne sub is actually 10 ohms, and this amp puts out 497 watts RMS at 8 ohms, I'd be pushing maybe 420ish watts to my rough estimate max from this amp into my Velodyne. The velodyne is rated at 400 watts RMS. Does signal to noise ratio at 98db mean it's impossible to push over 98db from the sub hooked up to that? because my sub is rated 104db @ 20Hz with 0.5% distortion, can push over 120dv with a little under 3% distortion.
meaning, I'd be 98db maxxed out with 0.92% THD from the amp, meaning that amp will literally bottleneck my current sub driver?
Then again, I have no idea the performance difference with the servo activated or not activated. The servo is an accelerometer attached to the the inside of the cone of my sub driver which measures woofer movement about 3500 times a second and re positions the diaphragm accordingly, which actually works somewhat like noise canceling technology in order to greatly reduce distortion. When the servo worked, it was the best sounding sub Iv'e ever heard. I really have no idea how the servo affects things, can someone point me out on this?Edited by coreyL - 3/2/11 at 12:23am
