Just to let you know, I'm really new to the whole building speakers thing, but I have put a couple of cabs together, and thrown various drivers in, and they sounded ok...and I've enjoyed building them. But now, I'm trying to get a little more indepth with the speaker design. I am building a pair of 2-way speakers roughly bookshelf size, to be used outside under the eves of our garage. I ran WinISD, and came up with the following:
Dayton 295-335 7" Aluminum Woofer
Volume- .4 cubic feet
Vent Length- 4.76"
System Input power- 65 watts
I plan on using a 5000hz 1st order butterworth crossover to split the frequencys. I can post some screenshots of the graph if needed. My problem is that, if I don't use a high pass at 100 hz, the woofer is running out of excursion before the tuning point (so says WinISD). Also, this high pass is hurting the SPL in the lower frequencies. Can anyone critique my design for these speakers? I'm trying to get the best bass out of them that I can, as there will be no subwoofer outside, and these will be handling the full range (with a tweeter of course). Can someone help me out, or is this ok to build it with a high pass at a 100hz to limit cone excursion. As expected, the SPL graph stays higher at lower frequencies without it, but the cone runs out of excursion without it (according to WinISD). This is one of the first times I've used WinISD, and am slowly learning how to use it too. Also, could some one explain the transfer function magnitude graph, as I'm not sure on what its used for. Each enclosure will have one Dayton woofer, and probably a Pioneer tweeter. Thanks for any help.
