[QUOTE="Vaughan, post: 67589, member: 693"] I would also recommend an IB if you are able to accommodate one. What size drivers do you want to use ? Why do you want 30mm+ one way ? Once you get over the 20-25mm travel barrier the costs skyrocket. This is what I would do. Get 4 Dayton IB 15" woofers (around 15 mm one-way travel), build a manafold large enough to accommodate 8, then if you feel you need more displacement, add more drivers as required. I don't believe you have factored in room gain so add another 8-12 dB's or so to your measurements. Your power requirements will be cut down significantly in an IB so thermal compression effects will be reduced significantly so at the end of the day, you'll save in the long run, plus you'll prolong the life of the system. Also, 8x IB15 woofers will provide just about all the displacement you could ever possibly want in a home. Just my 2c. [/QUOTE]
