Custom Vifa Speakers

zingo

I just picked up this pair of speakers from a local builder. For the monitors, he used Vifa silk dome tweeters and 6.5in woofer (I haven't removed them yet to pull the model numbers), crossovers with Solen caps and air core inductors, and 3/4in MDF cabinets generously braced and finished with real oak; each probably weighs about 25lbs. Subwoofers are a seal NHT 1259 12in woofer with similarly constructed cabinets at about 80lbs each; active crossover included.

I just started playing with them, but they appear to be well designed speakers with a fairly neutral and polite




sound.

Dang those look sweet

Nice sounding speakers for sure that are easy to listen to and error, if anything, on being too laid back. They have a bit of a boxy sound at times, but my daily speakers at work are magnetic planar. I expected more bass from cabinets that big with the hope of not using a subwoofer for my home office, but I'm also comparing these to a pair of Camber's with 8in woofers.

The subwoofers sounded strong sub 30hz wired in series and driven with a meager NHT SA1 amplifier. For office duty, my small Focal 8in subwoofer will do a good job, and I'll play with these big guys for HT duty.

The volume of the cabs look correct for a garden variety of Midwoofers. They look like a poly cone MW. It would be neat if you could swap in a Polk MW with doped paper.

Looks like a rebuilt DR7, very nice

You are correct they appear to be a DR7 clone; kewl! Nice sounding speakers with 1" braced cabinets, so a fun find even if I want to tinker on them.

I bought some Parts Express grills for the woofers, and they give them a very nice look. I also picked-up a used Behringer NU6000DSP to power the subwoofers. It's a neat amp with great programmable DSP, tons of power, and fans that are a little louder than I hoped... However I've just started playing with it's crossovers, filters, and other features.

Looks like the builder did a very nice job on the cabinets!

Yes. The cabinets alone were worth the price of admission. Having done builds with the NHT 1259 before, they are very nice drivers in seal cabinets, but don't have the power handling or excursion of more modern woofers. I have the power on the amp limited to 1000w per driver, but if I accidentally toast them during a movie, the large cabinets would be perfect for a variety of drivers.

Same with the monitor cabinets; the drivers are showing their age with some plastic fatigue, but there are many well designed 2-way monitors I could instLl in the roomy and ported cabinet.
