I had a chance to check out TacoTunes new ported box in person this weekend (http://www.youtube.com/watch?v=NP7T31GkS8E) and thought I would take the opportunity to review it and compare it to my sealed system.
First of all, system aside, Shane's truck is awesome. Shane, if you see this post, much respect for the work you have done on it. My truck looked downright tiny sitting next to it. Loved the train horn... that pair of underwear will never been the same.
Shane has the new ported box with a single Image Dynamics IDQ12v3 sub running off an Alpine PDX 1.600 mono amp. He is running Image Dynamics components up front and and coax's in the rear, all powered by an Alpine PDX 4.100.
I on the other hand am running a sealed TacoTunes box with a single Image Dynamics IDQ10v3 sub powered by an Alpine PDX 5. I have Focal components up front and coax in the back running off the PDX 5 as well.
Both systems sound fantastic, and what I found comparing them side by side is that it all boils down to WHAT you are listening to.
Shane's system is loud and hits hard, really hard, particularly on the very low base. Since Shane primarily listens to Hip Hop, thats perfect and Hip Hop sounds just the way it should on his system. However, throw on some Metallica or anything that has very fast bass transitions and it starts to show it's flaws. That ported 12 simply cannot keep up with extremely fast bass hits, it all starts to get muddy. Not what us metal heads are typically looking for.
My system is plenty loud as well, more than most people would use on thier daily commute. My sealed IDQ10 can handle even the fastest feet pounding on a set of double bass drums, the IDQ has an amazing recovery time from one bass hit to the next. However, if you are looking for big deep rumbling bass in Hip Hop, that's where my system shows it's weakness. It just cannot move enough air to make those deep lows rumble like they should.
So, in a nutshell, both TacoTunes boxes and ID Subs are excellent. If you are looking for a system and trying to decide between the two, consider the music you are listening to. In two identical Taco Sport Double Cabs the two different boxes definitely stand apart. If you are a Rap/Hip Hop guy, definitely do the ported box with the 12. If you are a Rock guy, stick with the sealed 10.
I anyone wants input on the Alpine amps, Focal or ID speakers, etc.. I have had the pleasure of experiencing both so please just ask. Keep in mind, this is all subjective.
