Default Full-range to replace Pioneer PE-12

WINisd led me to build 616 cu in vented boxes for these old drivers. Now I want to use the same box for some modern drivers, maybe give them to my brother for Christmas.

Any suggestions?

Pioneer PE-12 is a valuable driver, which sound I enjoy very much.
However it needs support in trebles.
If you want to replace it, the new driver should have a better frequency range and similar T/S parameters to fit in the same enclosure.
My suggestion is TangBand W4-1320SB, SD, or SJ
It is available in Parts Express
The ferrite versions Tang Band W4-1320SIF and Tang Band W4-1320SJF has similar datasheet, but, unfortunately not the same performance in highs as SB/SD/SJ and will need a tweeter.

I have wondered which driver could replace the Radio Shack 1354 which to me is similar to the Pioneer PE-12. The TB 1320 seems like a much more modern product, is smaller and has a different sound - almost sounding like a mellow two way. I really like the 1320. But the little Dayton pro driver sounds really good and it's cheap. Tho the specs are not as 'fullrange' as any of the above, in practice this driver doesn't need a tweeter (IMO) and goes deeper than its spec. It produces a full and rich bass in a BIB. Realistically, in smaller boxes like the one pictured above, I wonder if it's fs of 90hz isn't too far off the mark?

Thoughts on the Dayton as a full range driver in a bookshelf enclosure? To me, it sounds better than its specs would indicate and has become one of my favorite drivers for listening to music. I intend to try it in a bookshelf and on open baffle as well.

Godzilla, are you listening to this driver wide open, no filters? I thought about using two of these in parallel crossed over to a 15" PRV somewhere between 350-800hz for a combo bass/acoustic guitar cabinet, but the frequency response curve looks horrible, as compared to, say, FaitalPro 4".

i have been using the pe 12 for over 20 yrs as a reference speaker when i used to fine tune amps,mixers,tt etc while i don't do that anymore, i still listen to them weekly ,this is a magic driver and not a lot comes close to it,i have them in a 0.5cftbox stuffed and the same tweeter and crossover as the pioneer cs51 except i have recessed the tweeter an inch so as to time align them and some new caps
the only other fr that come close is the ROR audio research type e speaker albeit not as delicate and sensitive ,they were designed by Ted Rothstein(hero in my world)

the best modern guy i found about 5 yrs ago was the Lowell Mfg - JR410 Series: 15W 4" high compliance driver

i have them in 0.25cft sealed stuffed cabs and my triodes love them , they are cheap and surprisingly good ,the sound stage is wide as hell

I seem to remember the Monacor SPH-60x getting some good comments a few years back, and it looks to be the right size.

616 in^3 ~ 10 litres

Of the drivers i have worked with, Fostex FF125wk, FX120, Mark Audio CHR/CHP/CHN70, Alpair 7.3 work well in this volume. Vent would need suitableadjustment foreach.

Thanks for the interesting suggestion soulsheiksan! Sometimes drivers that look utilitarian are the best because the are purpose built. Excellent!

Tico, yes, I listen to these wide open in BIBs and they are great. They have an ease of presentation that really sounds fun and realistic. They are light on their feet and play loudly. They look purpose built and utilitarian. They are no nonsense drivers.

But the specs and measurements are what kept me away from the little Dayton. After listening to it for a while, I believe all of the other manufacturers are posting heavily smoothed curves. You don't hear the ups and downs rather the general trend. Regardless, the specs are not quite right for this little driver but the sound it produces is very good IMO.

Thanks for all the ideas. I decided to try the Mark Audio CHR70. Price is pretty good, I might try one of the others later on. I'll report back!
