Prv 4mr60-4 is very good. There are many others worth noting.

I'll be doing a build with that 4" "OEM" SB driver here soon. I really was impressed with what I heard of it running fullrange at Indy this spring. It is under $30, and has a very good response through the anticipated pass band, and models really well as a dedicated midbass for small 2-ways, as well.Don't listen to me - I have not sold any $150,000 speakers.

I've had my eye on using the SB12NRXF25-8 for some time. Incredibly smooth response.Constructions: Dayton+SB 2-Way v1 | Dayton+SB 2-Way v2 | Fabios (SB Monitors)

dougc the two option you listed are like comparing apples and pears - assuming the 2” mid is the RS52AN dome mid range.
The RS52AN-8 will only go down to around 500hz at a push, more like 700hz usable but will go up to 8khz plus and has a sensitivity of 89.4db/W/m. The RS125p-8 can be used down to 100hz but tops out usable at around 5khz and is 2dB less sensitive. Also the 2” can be placed like a tweeter in the same volume as the woofer whereas the RS125 will have to have it’s own enclosed (probably around 1-2litres, sealed). So, it really depends on what drivers are above and below it and what range you want them to cover. Finally off axis dispersion is different for a dome compared to a cone so this may be a consideration.
Just a few thought.

Ok i'll give my main speaker bio. each speaker consists of 5 drivers, 2 Vifa PL18-8 woofers , 1 Vifa PL 18-4 midrange, 1 Infinity 5" mid (blown,replacing) ,1 BG neo3 pdr tweeter. They are awesome speakers but the 5" mid is blown. I bought them at a speaker close out @ PE about 12 years ago

If you still have your B&G Neo8 PDR midranges, then one each of those might work well as upper midrange paired with one each of your B&G Neo3 PDR tweeters. Use the pairs of Vifa PL18WO09-08 for lower midrange.Last edited by JRT; 07-31-2022, 11:44 AM.

Hi Dougc,
The speakers will probably sound better with a single mid-range driver rather than multiples. More isn't automatically better with speaker systems. Might be better to ditch the extra mid-range driver to avoid destructive coupling/lobing/smearing/etc.Pro/Fi Cinema Speaker project: "From the Ashes"

Either way, if you can't purchase new units of the blown midrange or have them repaired you can't just swap in another midrange without redesigning the crossover.
The 'best' midrange is the one that integrates with your other drivers.
