That should let me make a fair comparison of the PB13 and the PB16 for you. I had multiple Sledge amp PB13's, and I kept one of them as a nearfield sub, when I traded up for my 16's.
I would not say that the PB16 completely blows the 13 away, but it definitely has a deeper and more authoritative sound. Some note its smoothness, as well, but I would rather concentrate on output. The max output above about 35Hz is the same for both the 1000 watt PB13 and for the PB16. Where the 16 pulls ahead is in the lower frequencies, where it averages about a 4db increase. That would probably be 5db, compared to the older 700 watt PB13.
To put that in perspective, at below about 30Hz, a 5db increase in SPL is perceived as a doubling in volume. That's an idiosyncrasy of the Equal Loudness Contours, where ordinarily a 10db increase in SPL is perceived as a doubling in loudness. That is, in my opinion, the reason that the PB16 has a somewhat weightier sound than the PB13, even at moderate volume levels. You would like the new PB16, and it looks cool and has some nice features, but it wouldn't be a night-and-day difference from your current sub.
Thanks Mike.I compared the specs and they look impressive for sure. I wish someone that has a PB 16 Ultra that lives in the DFW Tx area would play it for me.
The 1st owner (Greg) of my PB 13 Ultra received the new Sledge when the BASH failed then he fried that Sledge a few years later and replaced it with another new one. Then he sold the sub ( he has two) to my friend and we JAMMED it for several years then that Sledge failed. Owner #2
my friend (james) purchased a new Sledge 1000 in Set 2014 and it's good until 2019.
SO now the 4th amp ( one BASH & 3 Sledge) has just failed and it's about 10 or 11 years old.
I used a Ohm meter the driver reads just over 4 ohms. I used a 9 volt battery and cone made a stroke. Wires from driver to amp look perfect except for one othe the spades on the end of the woofer wires that slide on the board (the black Ground ) - is melted on the board.
Plus the insulation smells like burnt wires etc so I have a fan on low blowing fresh air thru the open end of the cabinet until the new Sledge arrives next week.
Just my bad luck as so many SVS owners never have this issue like this one has had. But BOTH owners before me had it in a HUGE room and it needed several 16's in these rooms to get the" Tactical Hit" this one 13 does in this 10x14' carpeted den.
I have it turned down big time from where it was set at in those rooms. Cross my fingers this amp will last a bit longer then the others have. I will call SVS when I install it and make sure I have it adjusted correctly to start before I run my AVR room correction program.
