I have reached out to Nathan and he seems like a real nice guy who has given me various options to work with.

Just going back a little.. so it seems like a consensus here that I should give the JL F212's a pass.

Anyone have any thoughts on the Seaton's Submersives which have quite a following as well but have not been tested by trusted third parties as yet..

This decision is not easy.. I just wish I had the moolah to buy them all:)smile.gif

I would wager that a 18.0SE from Nathan will stomp a F212 in output. The Seaton SubM is an excellent sub, a little larger and more money but another top quality ID sub.

At what SPL? Post the graphs or it didn't happen.

Here's an 18.0 for comparison purposes (80 Hz crossover):


And a quad TSAD FA custom:

For a sealed 18 with 2.4kw that's pretty expected I would think. I don't think that's what Craig was questioning though. Nice subs BTW.

Thanks. No matter how hard I tried, I couldn't get rid of the little dips. frown.gif

Part of the problem, I don't want room treatments and I really don't want to add a third subwoofer. In frustration, this is what I'm going have to live with.

(oh boo-hoo me)

The dips, particularly at 51 Hz, are probably too narrow to be audibly significant. Perhaps one or more represent boundary cancellations?

http://www.padrick.net/LiveSound/CancellationMode.htm

If so, moving the sub closer to the boundary could raise the cancellation frequency above the crossover point, effectively eliminating it.

Thanks.

From the left, to the right, the first dip is 2 Hz wide. The second is 3 Hz wide. And the third is 10Hz wide.

(with what we have, we all try hard for a clean, uneventful, unsmoothed, +/-3dB graph)

A worthy goal, frequently unobtainable without scads of EQ however...
