With the advent of the Simplexx line, we get to see how a competently designed bass reflex can perform. At least by the SPL charts, these cabs look pretty respectable in sensitivity at a reasonable size.

What excites me is the ability to see how much better Bill's horn-loaded designs work than the reflex boxes, and to be able to compare charts that have been prepared with the same methodology. Since I found this site, I've been skeptical of charts supplied by cab manufacturers. If you were ever wondering how impressive a J10 is, compare it to the Simplex 10 charts. After about 100 Hz, you can see where the horn kicks in and the J10 leaves the S10 in the dust. Throw the same 2510 in a DR250, and hold on to your hat (admittedly the DR250 is in a different size class) .

So I'm sure folks who aren't interested in building horn-loaded cabs are thanking Bill for designing an easy to build reflex cabs. I'd like to thank Bill for providing worthy reflex cabs to compare the horn-loaded lines to.

I noticed the same thing when seeing the charts for the simplexx line. Years ago, when drooling over specs in audiophile mags, I paid close attention to charts. Most units would peak at 87 - 93 dB/w/m. I thought I was king of the block when I got my hands on some vintage Altecs that were 104. Now I'm flying high with my T48s! Now I gotta build the rest of the fleet!

Also, kudos for Bill coming up with a catchy name for an easy to build product line....
(At least it seemed catchy to me when you say it out loud as Simple-x-x. Sounds kinda like something you just fall into. (At least that's my excuse.))

What I find interesting about the cabs is that they are interesting to people on this board who already have horn loaded tops and subs! Many of us will build them just to try them out, and I predict will be impressed with them --- until we fire up our horns! Seriously, that's what I foresee. Of course, a lot of people will want a faster build than DRs or Otops + Tuba or Titans and these will fit the bill - UNTIL WE FIRE UP THE HORNS!

This made me think of everyone getting together in a field with their gear and blasting some tone sweeps while the rest of the world thinks the apocalypse is here.

I'm game where's the field?
