Here are my challenges for which I could use some advice; do I stick with 24 ohm diaphragms or opt for 16 or even 8?

Hi Jeff ! This will depend on your amplifiers.What will you be using and what are the ratings on them ? The 24 ohm aren't used much anymore mostly 8,16 ohm.Also the biggest factor here is what size,kind of (Hardwood,Concrete) room are these speakers to be used in ? All these factors will have an effect on the quality of sound they will produce. But first size,is there any limitations on the actual size of the LF enclosures you can use WAF,etc, ? In my personal Opinion any of the large format drivers should use dual woofers.The 288's are a lot more efficient than the 515's if single woofers are used, 288 will have to be padded down ! Or it will sound very bass shy (All Mid-HF)
