Hi,
Well the peerless units are not expensive :
Peerless 8" SKO204 hifi bass speakers woofers 4ohm | eBay
the SPH10's are 8 ohm not 4 ohm.
One simple option is to forget about Linns marketing hype, forget about
two 8" drivers in such a small box and use the whole box for a quality
8" driver, i.e. simply remove the rear one, use the best quality 8" 8 ohm
driver you can find, with ~ double the xmax of the B200 with one of
the crossovers. Of course it has to suit the total box volume.
Sell the drivers and c/o's as spares.

I think I might try the Monacor units - Wilmslow Audio seem to rate them highly as replacements for the B200 but I wont scrap my saras yet - I think I will wait unti I see a damaged pair on Sleezebay and then modify them. Curently the Saras are performing wekll - I just have to be carefull not to overdrive them again.
Re making them into a single bass speaker box - what's the point? - I doubt I will ever get the same bass response from a single unit no matter what it's spec.

Is there a way to limit the low bass for cannon/gun fire? E.g. Lexion build in "bass limiter" settings right in the menu and you can set it where you want.
Also I would have to think the major sub woofers manufactures build-in protection circuits, or they could never offer a warranty.
Hi,
I don't remotely trust Wilmslow Audio "advice", its usually pathetically poor.
As to the above point you couldn't be more wrong, isobaric is not magic.
You can always make a single driver that is the same as a isobaric pair.
The problem is finding the right equivalent driver, that's difficult for 8".

Perhaps the "Best" solution is a new set of speakers with better parameters using the same "Footprint" as the Saras
Yes, like the STUDIOSPARES SN10 PASSIVE NEARFIELD MONITORS. Just an idea.

They are 80 watts RMS (8 ohms) anyway.😎
If you are going to series the two Kef B200, try to half the cap across the two woofers from 14uF to ~7uF (or adjust). Leave the inductor 0.88mH as-is or adjust (in/out/plus). In fact you are doubling the impedance (Re=7.1 Ohm) on the low pass filter and adding a driver inductance (Le=0.42mH).
Thanks for this but I dont intend to put 2 B200s in series - only two 4ohm Peerless units as replacements for the B200s - The origional B200s are 8 ohms each and there are two identical crossovers in each box one supplying each B200. By putting two 4ohm units in and removing the second crossover I hope to simplify the load to the amp but keep the impedence correct for the crossover.
The idea is to have simpler electronics (ie one crossover not two) , the same basic load (still 8ohms to the crossover) but higher power capability (the Peerless units being more power capable than the B200).
