[QUOTE="Ivan Beaver, post: 125367, member: 30"] Re: Meyer 700 HP Cardioid Settings, if you have them. It doesn't matter whether they are single or double drivers. Wavelength is wavelength so the spacing and delay will remain the same-no matter if you are using a single 8" or a quad 21". What WILL change is you determining over what freq you want maximum rejection. You do not get it at all freq. So YOU have to determine is it more important to have kickdrum freq (60ish Hz) or lower bass 35-40Hzish? That will depend on the style of music-how the system will be ran (freq response wise) and so forth. But the math stays the same. Determine your main freq of interest-find the 1/4 wavelength-space the cabinets for that and use that amount of delay. Now whether you use a end fire (best sound but less rejection) or cardioid (less impactful sound but greater rejection) is up to you-but the delay and spacing remains the same. [/QUOTE]
