... and found it lacking, what was it that you did not like? I see many who used it employed it in a 2 way and am wondering how or if your opinion would change on them a a small bass woofer in a 3way under ~300hz?

I tried the 830869 in a 2-way and I was not too excited.

However, in a 3-way, it is quite outstanding.

I usually cross at 125Hz, 24dB/oct active.

Hi mortron,
I have used it in a 2 way build that I completed last year. In my opinion, it is a fine bass driver that is now reasonably priced (esp. from Solen). If using in bottom of a 3 way, my choice would be to use (2) 830869's per side wired in parallel. Give them somewhere around 85-90 liters in a vented cab tuned to around 35 hz and you will have one nice bass section that will not break the bank.

Best Regards,
Rich

Four would be twice as good, no?

Hi Morton,
Treat yourself to a nice Christmas present. (4) Peerless 830869's should make a nice gift.

I have used it Peerless 830869 + SB26ADC-04 crossover help?

It needs to be crossed around 1-1,5kHz. If you design around that, it's a good woofer.

Thanks folks.

Michael - your Nightengale project was one that has me on the fence about this driver.

Based on some of what I've read, this driver is challenged some in a 2 way design. Would you say it's from trying to get it to cover a wider than satisfactory range? I saw once box size came down, you were happier.

Would anyone say that the 830869 lends itself to a bass or mid more than the other? Or is it one of those kind of drivers that you can use for both but should just pick one?

I want to use it for bottom of a 3way. Four per side maybe.

Hi mortron

I find the 830869 is best suited for bass duty in a 3-way.

It's not so much how low it can go but more the clarity of the bass notes.

Makes it ideal for music reproduction.

The 830869 is also excellent as a lower midrange in a 4-way.

For example, two 12" for bass (125Hz), 830869 for vocals (125Hz-1.2kHz), compression driver (1.2kHz-7kHz) and finally, super tweeter.

It is not that the 830869 sounds bad in a 2-way. It's all a question of expectations.

As for your 3-way, two 830869 with a Peerless 830870 and a Morel MDT29 would be perfect.


Hi Dave
Thanks for sharing your build. Your speaker is fantastic.
