If you didn't already make the trip....

I believe they're out of the $42 woofers. Infinity Kappa Perfect car subs seem like a good match, as do the creative sound trio 12. I'm going to be doing a few with the trio.

I bought a pair of the 8 ohm $42 woofer, but didn't ask about larger quantity. Talking to Dave (head Hamster of Hamster audio I think, guy who built the speakers DeepSurplus sold as complete units anyway) and it "may" turn out I grabbed my push pull cabinets from the "wrong" pallet, and may have a smaller internal volume and different sized amp plate spot. Hopefully sometime later this week I will get a chance to check.

Son of a gun.... it turns out that the half-dozen of the dual cabs I picked up were ALL the smaller size. Very disappointing as I could very much use the additional cabinet volume!!

Anyone who got some of the bigger ones and would like some smaller ones, or some of the other cabs (I have quite a few of the cherry vinyl-veneer boxes, some of the odd-angle "tubes", some of the gloss mini-enclosures, and a few other odds 'n ends) please let me know. I also have a fair number of grilles, for the larger peg-style sub cabs (they don't fit the cherry), so if anyone has these and needs grilles, let me know.

If the grills that don't fit the cherry cabs fit the maple cabs, I'll need a few of those.

Glad I found this thread.

I picked up 4 of the bigger single-driver sub boxes and secured the drivers from Deepsurplus (not bad for the $42 price at all), but these drivers only fit on 2 of the 4 boxes

I need to figure out how to widen the outer radius a little bit.. That drum sand looks like a good idea. Where did you get it and for how much?

Also 3 of the 4 boxes actually have plate amp holes that fit the M+K 250 watt plate amp (which I bought from Apex Jr), but the problem is they have pre-drilled holes with metal inserts on the other side, so you can't use the screws that come with the plate amps. Using what seems like the right-size screw, some of the holes/inserts lock in good but others just spin. They may be stripped from prior use (the boxes definitely look used).

I *was* able to assemble one subwoofer with the Deepsurplus driver and M+K plate amp, and it does sound very good, nice and tight. HOWEVER, I can hear metallic rining and pinging from the plate amp as volume goes up, which I can lessen by putting my hand on the heatsink/plate. I'm thinking about just sealing the plate amp hole with some MDF and use the plate amp externally. Will need to make plate amp enclosures

Looks like I'm looking at some significant woodworking. Any suggestions on good woodworking shops around Zip 91784 (Upland, CA)?

Can you post a few pics of the boxes that fit the 250W apexJr amp?

I got the drum sander at OSH but HD or Lowes should have them too. Just a drill attachment. Maybe 10 bucks?

Easier solution is to find the right sized cigar box, hack it to fit, and use that to cover the backside of the plate amp. you only need a hole for the speaker wire. You lose a tiny bit of enclosure volume but not too bad. If you'd like to take a trip to Tustin I'd be happy to help you with the job.

This is the first I assembled. For the next two, I'm likely going to house the M+K amp externally and seal the back of subs with something (mdf?).

For music, first and foremost, I look for subs that blends well with mains and provide defined bass extension without going "boom" "boom" "boom" separated from the main music. Thankfully, this sealed sub disappears really well while doing its job.

I do prefer how the line-level input sounds over speaker-level, but I have found that to be the case with most subs I've tried.

The M+K plate amp has no back plate, so not isolated, and I do hear metallic pings and ringing if I'm at the rear of the sub, listening. Thus my plan for externally housing the plate amps for my other boxes..
