330 shipped?

I have ordered drivers to do a 3 way active setup front stage in my truck. On pay day I might get back to you on this, since it would meet my needs pretty well.

Since I work in sourcing in the professional audio field, I can say that we buy Fairchild, IR, On-Semi, Vishay, NXP and Diodes Inc parts. There are a variety of other vendors but our spend with them is insignificant. Several of those brands don't sell directly to customers unless they...

Birch is light as hell. LOL

an offset of gain does not move the wave form 180 degrees forward or back. No, -12 dB does not equal a phasing adjustment. It is true that phase can become problematic near crossover points, and it is most commonly prevalent in midrange voicing, and with lower frequencies, because the wave...

port type is more important than direction, IMO. Square port vs. aeroport vs. octoport. Aeroport is most efficient. Best configuration is woofer and aeroport on the same plane, with enough space between the aeroport and the back wall to collect sound (more clearance than the diameter of the...

I might need one of these soon...or a Helix DSP...

The PPI have a cult following for being an excellent value. If you posted a poll here I would bet that the PPI would get twice the votes of the Kenwood.

another online calculator that works well, since the link above doesn't work. This is the one I like to use. Speaker Enclosure Volume Calculator Confirmed; for 3.4 cubes you can use two 4" aero ports at 16.4 inches in length to get you to 33Hz. Note, this is only 25 cubic inches of port area...

for the dash, most popular are going to be Fountek 89s from parts express. 6.5s for the doors, Silver flutes from Madisound Tweeters; Scan-speak. They are packaged with a $350 component set and sound fantastic. $58 a pair also from Madisound. Look on DIYMA.com or here. That is what the...

For aero ports, you want 7 to 9 cubic inches of port area per cubic foot of net internal enclosure space. Generally speaking. As an example, for the Sundown Nightshade Series suggests 60 cubic inches in a 4.25 cubic foot box. Those have a lot of excursion, which is a factor in port design. A...

Given the increase in cone surface area, the move from a 15 to an 18 will definitely be audible. Even if the 18 is in a box that is ample for a 15 but small for an 18, it will still likely outperform it. And, the 18 will likely have a resonant frequency of 2 to 3 Hz lower. However, these are...

The Martin Audio driver is an awesome driver. Wait...maybe I said that because I work for/with Martin Audio (technically LOUD Technologies).

Morel Maxximos are great. I have a set of the 6.5" components and they have better midbass extension and midrange fidelity than all the other comps I have heard in their class. The tweeter puts out too much for me, so I have to dial it back 5 dB through a parametric eq as the crossover doesn't...

I would love to see a thread that shows a grid of the most popular subwoofers with these types of classifications; i.e. preferred box type, preferred box size, if they perform well with ported enclosures, what they like to be tuned to, and optimal RMS power from a reputable amplifier...
