Review: Tekton Design 4-10 Subwoofer

Now to share a warning with others. My experience in audio is more car audio orientated and as an ex-installer I learned to really enjoy overloading or pressurizing the car with low bass notes. That is, my personal preference and mine leans towards bass heaviness.
Eric Alexander of Tekton Design has the 4-10 overall area surpassing an 18 inch driver in the 4-10 description on the Tekton website. I haven't done the math but I believe he's comparing the "piston area" of 4 ten inch drivers to the surface area of 1 eighteen inch driver. So why not just go with an 18 inch subwoofer? After all, Tekton does offer the Cinema subwoofer of 18 inches. Well, let me share an experience I had back in my days of installation, sonny. Lanzar the audio company set out to break the SPL record at the time using a mini van. They tried 8s, 10s, 12s, 15s, and 18s. The 12s from the Lanzar product lineup actually hit the hardest setting the record around 152spl. What I noted in demoing smaller drivers but more numerous in quantity to equal the overall area was tighter more controlled bass notes in certain circumstances. For example, in a very quick successive bass line what I heard with 18s was incredible. Lots of bass for sure, but the interesting thing is when comparing the 18s to more numerous smaller drivers is that I could hear the distinct detail of successive bass notes rather than one rumbling long bass note [bass hang] (1). That's just my subjective experience but one that has passed a personal blind test. Story time, when in San Antonio Texas in a night club outside Lackland AFB I heard some incredibly detailed and thunderous bass. I went to investigate and asked the D.J. what kinda subwoofers were they using in the establishment to rattle my drink glass across the table? His answer, "48 four inch drivers in some umph order bandbass enclosure".
Back to the 4-10. Audibly, in this system the 4-10 makes a world of difference delivering the heavy bass I prefer. I've hammered this subwoofer incredibly hard at high volumes and it hasn't failed yet. The problem I am having in the system if this might be considered an issue is that the 4-10 plays wonderfully from 20 to 120hz in the sealed enclosure. As you probably already know ported enclosures are tuned for a certain frequency and they drop and/or roll off outside the tuning frequency. Though the sealed enclosure in comparison plays minus 3-6db lower in spl the sealed enclosure plays smoothly the entire range from 20-120hz. I like the 4-10 crossed over at 120hz as it helps the 8 7inch mid bass drivers pressurize the room. And I won't be ecstatic until the hairs on the back of the listener's neck are standing at attention before the mighty Ulfs!
Anyhoot, the higher the cross over frequency the more localized or audibly present the location of the sub. In other words, crossed over at 120hz I can hear where the subwoofer is located [left side of soundstage]. In order to remedy this situation I can relocate the subwoofer, or cross the subwoofer over lower in frequency, as well as purchase a second 4-10 for the opposite side. Since a second 4-10 will increase the spl 3db or better I'll go with the second 4-10 subwoofer, ya don't have to talk me into it!
