In Reply to: What About This Example: Dayton 295-455 in 40" Baffle ? posted by Dr Deville on February 4, 2007 at 23:54:14:
Thorsten's modelling is usually pretty accurate, as far as modeling goes as opposed to real life. The Dayton subs are designed for low frequencies and IB installations, ie highish Qts. The combination of near-floor positioning (effectively increasing baffle size and adding floor reflection) and various room effects (for example placement near rear walls where you're effectively going from half-space to quarter-space) can add quite a bit to the lower end. We don't mount open baffles twenty feet in the air in a cornfield. That's why people report decent results even with un-EQed highish-Qts woofers like Altec 515s, which "should" rolloff in the 100hz range but in practice go lower.There's another OB effect which might (I'm guessing wildly here) be significant. Of course there is a lot of rear-wave output from the midrange driver, which it somewhat omnidirectional in the 100hz-1000hz range. This may add an effective 2db or so of boost for these frequencies, which can be very welcome for fullrange drivers which tend to have a high-frequency lift.
