  • What is the best crossover frequency ?

    How much of a noticable difference is there between a 100hz crossover point and a 150hz crossover point ? My main concern is that the top speakers don't sound "too" tinny. I still want a full sound from the tops with the added bass from the subs. Right now I have a crossover at 100hz but have been thinking about a new PV2600 power amp that has a 150hz built in crossover. Any thoughts on this ? Thanks

    I would be more concerned about how running subs this high made the PA sound...

      It all depends on the exact speakers. What are they?

        Usually 100 Hz is a good starting point but depends what subs your using and the room your mixing in.

          I usually find myself somewhere between 100 and 110 with most rigs.

            The tops are some older PAS 15" speakers with horns. They still sound fine running with a sub at the 100hz crossover. I am just looking at possibly getting a PV2600 power amp to power both subs and I see that this amp has a built in crossover at 150hz. I am just wondering if that will be too high for my liking. I just want a good full sound for mostly country and country rock. Thanks

              then run a crossover in the traditional sense. you cannot reinvent sound reinforcement.

                Get a Peavey IPR 1600 - crossover is 100hz.

                  Why don't you change the x-over point in your current setup to 150hz and see if you like it. If you can live with it, and really want to get rid of your x-over (and get rid of any x-over flexibility), then go ahead and replace it with the amp's build-in x-over.

                    The crossover I have now is also a built in crossover at 100hz in a Peavey cs400 so I am not able to change it unless I tried to find a replacement module. I like it but I need more power to run both subs. It will only run one sub ( good ) in bridged mode. That is why I am looking for a more powerfull amp to run both subs and hopefully get the built in crossover to go along with it. Thanks

                      I would expect a noticeable difference between 150hz and 100hz, YMMV.

                        The Yamaha PnnnnS amps have an adjustable crossover point built in.

                          there is not simply a correct frequency for a crossover ... it's just a tradeoff between a number of things. I wouldn't worry about it too much

                          Benefits of crossing over higher: More protection to tops for burn-out, less intermodulation distortion.

                          Benefits of crossing lower: tending to keep the vocals out of the sub.

                            There is no universal "best" crossover point. You have to use your ears to find it and it varies not only from cabinet brand but from speaker (JBL, EV, etc).

                            My UREI 525 has a built-in sine wave generator whose frequency is the crossover point. When this is engaged I can sweep it until the sine wave diminishes and that is my crossover point.
                            this sig no verb

                              Yes, I wouldn't worry much about it either.
