Nathans get a lift

Re: Nathans get a lift

I had them playing around 90db at my listening position (about 2m) and they were plenty loud and no hint of xmax issues. The little buggers take juice pretty well. They are currently being powered by my Adcom GFA555.

Good stuff. The slightly higher tuning probably helps, as does having a pair of them.

Thats the idea Lowell. The new owner is getting into old school vinyl. A "retro" style look.

Looks like a great woofer to pair with the Nathans!

These drivers are a great value. I've used them in a couple of applications - 1.5cuft tuned to 30, 2cuft tuned to 25, and even sealed for car audio. They run out of xmax if you listen at higher levels, but they're perfect for budget applications and "normal" listening levels.

Very nice. My dad amd I are about to take on a similiar build, using the same woofer.

While the Nathans do a very good job of producing bass down to about 60 Hz and sounding much larger than their size would suggest, sometimes, ya need a little more. The Nathans were designed to be first and foremost a desktop/bookshelf speaker so I incorporated only a couple of db of BSC.

The bass bins hold Dayton SD215-88 subwoofers and are a visual match to the DS115 above it. I did not want to go the plate amp route on these for a couple of reasons. First, these woofers are dvc, 8ohm per coil, so 2 amps would have been necessary. Nah not spending the money. I wanted the cabinets to act as stands for the little guys and get them up to ear level. So now what to do about a crossover? What I did was to use a 2nd order electrical on the subs, consisting of a 4mh coil and 147uf worth of cap, and a 33uf cap going to the MT section. This crossover is incorporated in the sub cabinet. This way if I want to just run the uppers, its all plug and play.

In true cheapskate, quicky type build bravado, I reused a pair of Yamaha 1 cube cabinets. I added bracing to the sides and top, doubled up the back and made a new front baffle of 1" mdf. The port consists of the internal flare of a power port and tunes the enclosure to about 35Hz. Lightly lined with mattress topper. The feet are 3/4" PVC pipe plugs and couplings, spray painted with hammered metallic black. The upper stand is simply OSB bolted to the bass bins with 1/4-20x1.5" bolts and painted with the same metallic black. The bass bin itself is duratexed.

They sound quite good and can take a pretty good amount of power. I am running them off of my Adcom GFA555 and they have no problem at all. On to the pics....
