Hi I was wondering what is the average and highest DB that two eights will hit in a ported box? I was wondering this because I had two peerless eights in a ported box that hit 138.2 at 57HZ but then I switched them from 16 ohms to 4 ohms and got my zapco 750 and they hit a lot harder im going to get it tested again on Monday probably. these are the eights I am using.

is that number on the Term Lab?? Seems like a hard to believe score.
There is no average db for anything...it is all woofer, enclosure, and install dependent.
I know someone who got 149.xx with two 8's. Asking the average output is like asking the average top speed of cars.

I dunno I've heard some loud eights before - I ran eights for awhile back in the day. Those eights look reasonably efficient with OK excursion - I'm sure they'd do great. But - yea - there really are not any hard or fast rules here - cabin gain, gain settings, etc., all add up for different results everytime/every car. I think I saw ur car over in the system photo forum - u have a hatchback right? I think a pair of eights on a big zapco amp like that would sound outstanding . . . I betcha real clean too.

Linky no worky.
Digital Designs is about the only company that has a high performance SPL 8 inch sub...they have a new pretty beefy 8 inch sub coming out soon.

I saw some video where 2 Soundsplinter 8's hit around 150 db's on a termlab powered by a Orion 2500 watt amp I think.

I have used the Digital Designs 8" a couple of times now and would take it over most other companies "good" 12" any day of the week. The thing absolutely thunders!!

Is the 1508 the one you are talking about Forbidden???
I've always wanted to get one and see what it could do. I really need some trunk space back..I'm getting out of the SPL thing.

The JBL 800 Gti is a true SPL 8" if you can find any . . . One of the few 8's with a 3" VC. In a half cube ported box this little guy is amazing!

I was looking around for some beefy 8 inch subwoofers for a 2.3 cubic foot box tuned to 35.6hz and with a zapco 750.2 amp. I was wondering if any one has used one of these and how it went, or if any one else has other suggestions on some high spl 8 inch subwoofers. https://www.audiopulse.com/products/subwoofer-drivers/epic

The audiopulse drivers are fantastic pieces. They are NOT designed as output monsters, they are SQ woofers.
The WILL do output, because of their power handling, but first and foremost, they are SQ drivers.
