For the price of four 13mH coils and four 400uF caps you can buy a 5.1 receiver. The cost of the same components for the sub low pass would pay for a... -
I assume you mean a passive high pass. They're almost never used between subs and satellites because they're prohibitively expensive. The inductors would...Leave a comment:

What people lose sight of is that tube amps aren't expensive because they're better. They're expensive because their obsolete technology makes the parts...Leave a comment:

The one instance where tubes are decidedly better than SS is in musical instrument amps, and then only when they're clipping. SS can sound the same, but...Leave a comment:

Tube are by and large more expensive than SS, audiophools equate quality with price. SS eclipsed tubes in performance roughly 40 years ago.Leave a comment:

I advise damping direct radiating subs even though it might not be needed, based on how cheap damping is, and that while it may not help it can't hur...Leave a comment:

If you don't need to go low don't, you just end up with a speaker that's larger than you need for no good reason. To be sure that you don't have a crossover...Leave a comment:

Those resonances would be of concern if they were within, or at least close to, the speaker pass band, but they aren't. A potential resonance only resonates...Leave a comment:

The .37 is net of the driver. I can't tell you what the driver volume is. That should be on spec sheets but very seldom is.Leave a comment:

The port exit needs to be less than 1/4 wavelength from the cone. Since the shortest wavelength in the port pass band is roughly 28 feet you don't have...Leave a comment:

Where output is concerned what matters most is the cone displacement, T/S spec Vd. It's the same for the HO and HF, and their maximum SPL is virtually...Leave a comment:

At the levels required for chuffing to occur I can't imagine being able to distinguish it.Leave a comment:

If you have room for the ported boxes by all means do it. If it turns out that your room gain makes the additional extension of ported unnecessary you...Leave a comment:

Polyfill does not affect the box volume. You probably don't need it. There's no midrange reflections to damp out with a sub, and in a car you don't really...Leave a comment:

I'd go around 1/3 cu ft sealed as well, but with the RSS265-HF 4. The higher Q gives higher sensitivity from 40 to 100Hz, which should complement the...Leave a comment:

Despite there being thousands of members until recently there were only ten insufferable jerks that made their way onto my iggy list. Two more made it...Leave a comment:

Audio is audio. Cabin gain is more obvious in a car because the room in question is particularly small. Jeff B's explanation was spot on.

Maybe, maybe not. The most improvement over a single sub comes with using two, with less significant improvement coming with a third, less still with...Leave a comment:

If Earl said that he's wrong. Cabin Gain is well documented. For instance:
