Seas L15 simulations
I intend to build myself a pair of small-ish active 2-ways using the Seas L15 mid-bass.
Seeing as WinISD returns some gigantic port dimensions, i decided on trying using these drivers in a sealed enclosure (in simulations).
The frequency response and cone excursion plots look good (up to ~50W), with a Linkwitz Transform (Qtc=.707, Fc=20Hz), and a 4th order L-R highpass (60Hz).
The thing is, i'm taking these results with a bucketload of salt (not just a grain), and i was wondering whether there is someone around here who owns a better simulation software, and is willing to do a couple of simulations for me (ported, and sealed, in the above-mentioned conditions).
Thanks in advance
I'd have a look at this ;)
Here's what I get out of WinISD.
Top trace (@ 60 Hz): vented box, 0.322 ft^3, 52 Hz tune, 2 in. vent, 8.22 in long.
Bottom trace: sealed box, 0.157 ft^3.
Middle trace - same sealed box with LT and high pass applied.
In my not-necessarily-expert opinion, the LT is hardly worth the effort. Lots of effort for at best a 3 dB boost. This is too small a driver to push too deep. For a stand alone speaker, the vented box should be pretty good in a small room. The sealed box would be fine with a sub.
