Heyya MOD freaks & pimp-out warriors....

My next victim has been decided by fate to be the mighty NATIONAL PANASONIC RS-4630DFT. It is a tank of truly monolithic proportions, a huge full-swing, full length top handle, 6.5" woofers, 1.5" tweeters, it looks like & a very heavy & quality build. The cabinet is rigid as hell for a portable & very deep, boxy.

Now, to finish off this exquisite power house, they decided to equip the blaster with very stiff, mid-happy woofers with a small 5/8" voice-coil & a screen for a dust-cap.....wow!! Any kind of bass would just fart up in those stiff paper cones & create a mess of any music I tried including, easy listening.......BLAH!!! I had to do something about it.

I don't have a manual but the deck is worn out & it only gets mono FM so I feel a bit cheated by this buy so what's a playa' to do YO!?! Mod that mutha OUT!!!! :dj-party:

Stay tuned......

Here's the specimen chosen for the next MOD. I haven't come up with the name yet. All depends on the way the project shapes up....
I've already installed the replacement woofers & so far so good...have been listening to blues to start out with & will end with some heavy dub to give it a good workout before I give it the Chronic-beats(c) certification of sonic goodness....

Well, the original woofers were 4 OHM & very, very, VERY stiff. I managed to shoe horn the BOSE 2 OHM woofers I used in my SHARP 777 resto & it sounds very good, lots of warmth without the distortion of normal boom-box woofers & plenty of POWER!!!! I used 6.7uF Polyseter Film caps for a 4Khz roll-off. This thing has to be putting out a clean 15+ watts per side & the new woofers work like a dream & probably pull out a good 30w per channel in the bass regions...


Stay tuned....video coming soon...

'I could probably stand on them and they wouldn't move' - funny **** :-)
It sounds real strong now!!!

As a side topic, you inspired me to try and improve the bass from my RX-5150 by fitting speakers that I know sound good in their donor boxes - I tried M9998 and then M9990 drivers - similar wattage and all 3 ohms speakers--- result: it sounded much more powerful and bassy with the original Panny speakers!? Same 3 ohm rating for all three speaker types! Got me buggered - I put the originals back in and it sounded strong again ( just not real bassy but better than with the Sanyo drivers)

Weird,

James.... :-)

Ok cool. I'm going antique shopping and texmex lunch with the woman. I'll be out and about till later. Even selling the M90 you modded? Got anything else on the selling block? I am on market while cash is available.

So you were kidding about the steel cutting, laser tweeter replacements thing? Aww, I was looking forward to seeing them in action. :lol:

That is so kick ass!! I have a Panasonic RX-7700 boombox, silver in color. Low mileage boomer, and am curious in what speakers you used to replace the originals? Any cutting or mods inside unit? The radio is very loud and can handle some bass but could use some efficiency in speaker department. Thanks!

Thanx! :-D

Uh, all depends on the original impedance rating of the original drivers. You have to stay within a couple of ohms of the originals. If you go too low, say 2 OHMS, & the originals were 8 or 6 OHMS you could damage the IC's. So far, I've had luck swapping out 6.5" speakers from 4 OHM to 2 OHM BOSE CADDILAC woofers.
