Looking to increase output on my Linn 5150s through the back door. Not sure how efficient existing drivers are but from experience it seems like they are probably around 88-90db driven by a 200 watt amp. I'm thinking 99-102db should do the trick. Hoping someone can help. TIA
To truly dig to the very bottom, the numbers of the Dayton DCS450 sound great...Eighteen inches worth, 95.9 Db, inexpensive, can SIM an F3 in the low twenties or teens if you are adept at retuning...
It seems when one tries to sim out the loads of so-called "Pro" drivers, you get a few more decibels, at the cost of reaching really low.
Sorry, I'll make that trade-off, the very nature of low frequencies should be paramount.

Had a look at 12" sub drivers on Parts Express. Most are 85db, with the odd one reaching 89-90-ish. Don't know where you're going to find sub drivers that are 10db more efficient without going to pro PA style drivers, which are completely different.

Just to clarify a bit. The Linn 5150 are isobaric subs with two 12" drivers. They are flat to 15hz and sound as a real sub should. I just want more output without altering the inboard dsp/amp system. So if it's 12" and seriously efficient capable of handling 200 watts, I'm game, pro driver or not. Mind you it needs to go as low as the present drivers. Not sure how much influence the isobaric configuration or dsp has on present specs but they probably have to have an Fs of 20hz at least
Pro PA style drivers are completely different, and won't work in your existing subs. If you want more bass, then you'll either have to buy bigger subs, or build something.

I don't want 'more', I just want more output. For example Beyma 12P80FeV2 but it has an Fs of 48hz. Give me a couple pairs of JBL 2203 and I'm good to go. Good luck finding even one of those, let alone four😎
Same thing, as you stated you want "more" output flat to 15Hz, which you won't get from the Beyma 12P80FeV2. You'll be lucky to get 50Hz from that driver. It's not intended to be a subwoofer.
jeff
Yes I know. It has all but the Fs. But the 2203 has what I need in spades. There has to be something similar out there. The 2203 is by no means new tech
Correction. The 2203 is 91db efficient, not high enough.

It doesn't.
I found an old spec sheet for the 2203H. It's rated sensitivity is only 91db.

If you want to simply replace original 12" drivers with a more efficient ones, it will not work. Hoffman's Iron Law.
You need a new, much bigger enclosure, new and much powerful amplifier and new DSP settings. And 18" PRO woofers instead of 12".
Ideally need to find more of the same drivers to create arrays to parallel with the existing subs.

What you want is physically not possible, a small driver, high efficient and an extreme low response. You can only choose 2 of those factors. That is the so called Hoffman Iron Law. You can't bend the laws of physica...
So I have just acquired four more exact duplicate drivers of the 5150. Lucky lucky 😀
Old thread but still on it! What benefit would there be to cut the tops of the 5150s and mount an opposing clamshell pair and run them parallel with the existing pair? Vibration cancelling/less distortion but would there be more output? So 2 opposing clamshell pairs in the same existing box.
Same as doubling up drivers, i.e. [2x displacement = + 3 dB] +[2x power = +3 dB] = + 6 dB total available.
