I bought 4 subwoofers and I'm absolutely not doing a DBA! Hah!


I just received shipments of 4 subwoofer drivers and they will not be going into a distributed bass array. 

I'm replacing my left and right speaker stands with powering subwoofers with 2 subwoofer drivers each.  I call them powering because they will be powering the 2-way monitors that will sit on top.  Here's a beauty shot of the insides.

The amp has all the DSP power I could need to produce perfect speaker measurements.   I wonder if JA at Stereophile would wax poetically if I priced them high enough?? laugh

Hey @barts  - Honestly always a conversion more than subwoofer addition.  The upper crossover point will depend on how they measure in cabinet and with the upper sections in place.

The advantage of subwoofer appliance is freedom of location in the room.  The disadvantage is you can't go higher than 80 Hz or so.

You might want to check out Stack Audio Auva footers for the subwoofer (without using the spikes.) and their Auva EQ footers between the monitors and bass unit.

If you need to keep the monitors low, consider 50mm Soundeck Mk2 Minis Damping Feet. They are about 3mm thick.

Reviews for all of these are online, but I'm speaking from extensive personal experience. I don't comment often here, Erik, but I respect your contribution to this community. Thank you.

You probably know this but just in case and just a suggestion: check with the driver manufacturer’s specs on the cabinet’s internal volume? 

@iseland "Plateamp": I moved my "plate amp'' out of the sub box into a separate housing. Its still a plate amp (components mounted on a plate), just a 'plate am in a different housing'.

Given the same space for the sub, I wanted that extra volume for the driver, and it allows me to swap out amps/crossovers, or use the 'housing amp' to drive other subs. 

Its the 2nd post I read today that mentions "enlarged soundstage"
and "air" in the context of woofer/subwoofer ("2 subs provide enlarge soundstage and more air"). 

I never brought the low frequencies in context with 'air' and 'soundstage'. 

Should I start thinking adding a 2nd sub (2 smaller ones instead of 1 larger)?
