Correction - most shops tie into the sub because they are 2 things - 1) lazy b) stupid.

Agreed. And to clarify the reasoning behind it, the woofer is only controlled to the tuning frequency. Anything under that cause it to "unload" since the air is no longer flowing in/out of the vent, and before you really hear the distortion, your woofer is feeling it. If you let it go too low, you let out the magic smoke.

I concur on full range channel (can be rear, too, FYI, just not sub).

LOC = high to low converter.

In a word, no. This is a blanket answer and doesn't work here. Why? Because the Q and center frequency are adjustable on this amp, as evidenced by the pitchers (which we will discuss in a minute). As for better SQ, IB is good, but the power requirements are more than a good sealed enclosure, and IB is much more challenging to get right. Lexi are sealed well, but still require a bit more for a good IB application.

If you have your bass EQ on, your center frequency should not be 20. You are, essentially, boosting at 20 Hz, which your infrasonic is then cutting off. You also have the Q very narrow at 0.5. I suggest raising the bass EQ center into a usable range, such as 50 Hz, and increasing the Q to around 0.7, since this will allow it to affect more frequencies around that center frequency. If you choose to use the bass ****, you should keep the boost on the amp at 0, as you do not want to send it more signal than it can effectively handle.

I noticed in the pitcher (4th one) that your input sensitivity seems to be halfway up (but since it's a pot, that could just be the way it was installed in the amp itself). If it is halfway up, that's entirely too much. With a LOC, you are feeding the amp quite a bit of signal, but if it's done off a sub output, they may have bandaided it by doing this - and distorting the living bejeezus out of the signal at the same time.

I suggest changing the input to the LOC and readjusting the gain (AKA input sensitivity) correctly, along with the above, and you should see much better results.

PS - I have to disagree that a vented enclosure can't sound good. Provided the rest is setup correctly, they certainly can. Expecting extremely tight bass, however, is another story. That takes a lot of tuning and experimenting, which most shops are want to do.

thank you for the reply. I will keep posting and updating how it's coming along. I plan to call up the shop and tell them about getting the loc connected to a full range output from the back speakers and hopefully they wont charge me anything.

I will also try adjusting the options on the amp and see what that does.

btw can you tell me what the difference of using the sub output is vs the back speakers. How would it give it a better sound
