I'm working on a 2-way system using a stack of 4 5" woofers in a 50L box. My initial choice for the drivers was poor, and I've given up trying to get them to work. They have an aluminum cone and sound like a pie plate. I'm using the miniDSP-HD in an active crossover system and have tried all manner of EQ.
I have my eye on the Silver Flute W14RC25-08 as a low cost option and the SB Acoustics SB15NRX30-8. I like the low VC inductance of the latter, but it is pricey.
I've also just come across many Peerless options; maybe the TPY05W08O0088, Heritage.
I'm looking for any comments on these specific drivers or any other suggestions.
Thanks,
Chris

Yes, what Pete said. Let's first know what you have and how they measured.
DSP gives great flexibility re: the crossover, it's EQ abilities come into play when you put the speakers into a room.

Anything by SB is a good choice; even their "budget" line. Wavecor is supposed to also be good; some former SS, Vifa, etc. talent with them same as with SB. I have been tempted to try Wavecor in the near future; haven't heard anything personally yet by them though.
PFC – Sbacoustics
Speaker units
I tried one of the SB PFC line; a 6 inch; very impressive for something so inexpensive for sure; hard to go wrong here

Undamped aluminium cones tend to have a series of sharp breakup peaks in the kHz range. My Seas H1252s sound pretty awful unless you really go to town on those peaks, but once tamed, they sound excellent.
I'd recommend using a steep crossover as low as you can get away with.

Thanks, and my thoughts.
Hello everybody and thanks for the replies.
I'm using 4 Dayton RS-150-8 and a Morel MDT-32s. Both of the drivers, it turns out, have a bit of trouble making it to 1500Hz. The woofers seem to have a hole there. The Morel's are very clean, and I think I would be happy if I could cross them over at 2kHz.
So, I'm looking for woofers that can work well up to 2kHz. The problem with the Daytons is that 2kHz is so close to where the major breakups occur that it impossible to render them inaudible, IMHO. I'm using 4-pole LR xover and aggressive suck at three frequencies.
I'm pretty excited about the Wavecor now. It holds up well in the simulations (I'm using the Aeneas app. OSX). It has lower inductance than the Dayton and from the data sheet looks like the cone is fairly well controlled.
I like the SB15NRX as well (price is better than the Wavecor), but worry about if the cone is well damped enough, based on the data sheet curves.
Looking forward to any comments.
And thanks again for the help.

Looks pretty workable to me. 2kHz crossover point, bottomless notch on the ~6.5kHz breakup on the woofers. I'd probably go MMTMM, or maybe make it 2.5-way.
Got any measurement gear?
