Sealed enclosures are necessarily the best or most accurate. Why do you suppose there are ported, transmissions and horn enclosures for high end home audio? There has to be a benifit to these non sealed enclosures if people are using them. The problem lies within the "average" box designers. Many average designers and builders tend to forget the "transient" response in their enclosures...hence in accurate response and performance....hence...making the name of the ported enclosure look bad. What about incorporating...ported, transmission line, horn all together and then apply a perfect transient response? Result will be a great accurate ported type enclosure. Better than a sealed: Yes...in every way.

You arent at all likely to have a vented enclosure in an automotive environment with better

Your comparison to home audio is irrelevant, as its a TOTALLY different environment. You wont get a spike in response from the home environment, because typically you are looking at a tuning frequency of 20Hz or less, as well as a fairly large enclosure. Most HT woofers utilizing vented boxes have a fairly low Qts as well.

Horn enclosures also arent very practical in a car environment, as you cannot truly horn load a subwoofer in such a tiny environment. TLs are nice, but really dont perform altogether differently from an EBS style vented enclosure.

Personally, if you have a nice low Q low fs woofer and have the option, I prefer the sound of a good IB alignment to virtually any enclosure available.

if you already have FLAT response to 10Hz, group delay that is ALWAYS below 10ms, at ANY frequency, then why would you bother wasting time and space building another alignment that cannot really improve on the performance you already get from a properly designed sealed system in an automotive environment? Just doesn't seem like a particularly logical choice. In home and pro audio applications you have environments where sealed boxes will typically NOT have anywhere near flat response to 30Hz, let alone 20Hz, and thus an EBS styled vented enclosure makes significantly more sense, because it allows you to have excellent extension and you still get pretty good accuracy. The vented enclosures you normally see in automotive environments aren't anything resembling EBS style alignments either, and I would still fail to see what you would gain from such a design in an automotive environment. After all, you already have flat response ( and exaggerated

I wonder how much that good review cost them. Ehh, who cares, the technology was probably stolen from an oem customer of their's anyway and REbaged...

I asked Scott if he designed the 06xxx and he said: "Pike110... yes, I am the culprit for that one. " Just to clear it up.

good to know at least, i guess, not that it really mattered IMO, but i just like it for what it is a great sub, i care less if ghandi created it as long as it does what i like.

How do you like it accordman? I bought one about a month ago and have yet to get around to getting the box built and installing it.

I totally agree with you Warbleed. But I'm not refering to traditional ported types of enclosures.

Your right, no true horn exists in a car environment...but you can definitely take horn characteristics and apply it to ported type enclosures and attain very similar effects.

One of the main advantage to modified ported type of enclosure is by using port resonance to flatten out spikes. Also, the rear wave can be a huge factor in performance...especially when phase aligned and coupled together. Lastly, you can develope the waves at any desired location in the vehicle.

I have a 6.5" sub in my vehicle with 75 watts. Everybody whom gets in my car always guess that I have about (2) 10's or (2) 12's with about 800-1000 watts. But the most impressive factor is that it plays pretty flat all the way down to 22 hz. This box consists of three technologies: Horn properties, T-Box (not transmission line), and phase alignment coupling.

Tuan, I would love to see the plans for that 6.5 enclosure. I would love to build one myself. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
