The 650 is not a ported sub, it is sealed. One thing to try to give yourself better bass response is place both subs on opposite corners with opposing phases. That can help your frequency response even out. Another thing you could do is actually figure out your response and see what it lacking. You don't always need to add more woofers. In fact you would probably get much more gain out of proper placement, room treatments and then an eq rather than adding another sub.
Thank you avaserfi!
I tried what you said before you posted it actually, and it INDEED makes a huge difference, the HSU I have i switched the phase and the bass increased dramatically, the HSU is in the opposite corner of the Jamo, and it sounds terrific. right now Im playing the Jamo by itself and it still sounds terrific, I only use the HSU now for when watching movies for that extra oomph!
I had a slight rattle in the Jamo, which is how it was when I received it but I didnt want to open it up to fix that issue... Well I did. I carefully removed each of the 14 screws on the back and placed them in order after removing them to keep it as original as possible.
Let me tell you this sub as far as construction goes BLOWS AWAY the HSU. the MDF board is a solid 1" Thick all the way around, the subwoofer itself has a MASSIVE magnet compared to the HSU magnet. the amp is BEEFY compared to the HSU, and weighs a good 10 pounds more than my 2 pound HSU amp (yes i weighed them). I didnt disconnect any cables inside the sub though no need to!
I fixed my rattle, and i even found a peice of loose solder inside it! I will keep it as a momento. My Jamo is now rattle free and sounds even better than new! :P
So sonically, and construction wise, this subwoofer blows away the HSU, all the more reason I am glad I got it, and recommend it to anyone out there looking at Jamo equipment.
YOU CANT GO WRONG!
