I used a single enclosure from Parts Express. The chip amp and Bluetooth adapter are attached to the underside.

With the cord in place. I want to be able to unplug the power cord so it isn't always dangling during transport.

The portable system powered by a $20.49 Lepai T-chip amp, and connected via Bluetooth is operational. Any Bluetooth capable smart phone can play through this. Finding a socket to accept a PC computer style power cord was a challenge. This nifty unit with a lighted power switch and fuse turned up on Amazon for $5.

Yes. When my geezer multi-vitamins ran out, I took my son's multi-vitamins. Now I sag my jeans and have an urge to get a tattoo.

Welcome. I've owned several h/k 430, 630, 730 & 930 receivers. They've all sounded great (if refreshed, use Search function to find h/k refurb threads) with Klipsch Heresy, Cornwall and La Scala. Asking this group how Klipsch Heritage compares to KEF 103.2s is unlikely to produce objective opinions. That said, I've owned LS3/5As (KEF B110 & T27) for decades. They're paired with DIY transmission line subwoofers, each with a KEF B139. They comprise my modest HT. The sound is excellent, but I prefer Heritage for listening to music. To me, the high efficiency and low distortion of horns makes music sound more dynamic and alive, even with the modest but clean power of a h/k x30 "twin-powered" receiver. On the other hand, the KEF drivered Ls3/5As are very inefficient and demand lots of power to sound good, but not quite as good as Heritage.

Now my wife is laughing after I showed this to her.

You've expressed an opinion based on your personal experience. You can't be wrong about your opinion. If others want to buy a pair of each and set up a scientific blind comparison to then voice their opinions, that would be interesting. Nonetheless, it wouldn't negate your opinion. Enjoy the music. PS: To be truly scientific the experiment should be in the Southern Hemisphere.[]

I stopped at Tim Horton's for dounts. I powered them in the parking lot with my phone. They sound and look great.

Russ- When should I go to Grand Blanc?

Russ- Not to worry. I'm the one who was lost. Thanks for helping a blind squirrel find an acorn.

I guess I never tried looking for it before, but where do I find the "Alerts" section? EDIT @ 10:28 AM EDT I see it's part of a "sub-forum" not dedicated to subs. These look very nice, but I'm not personally interested. It's about 45 minutes away. I'd be willing to help a member get these. I could collect them and hold them in our warehouse until arrangements could be made.

Perhaps there's a Pluto edition.

Dave- You're headed down a slippery slope now. After you replace the caps in your Cornwalls, you'll be an expert and doing the same to the pair of Heresy will be easy.

This reminds me of the old TV shows where the pilot of the small plane has a heart attack and the tower talks the passenger through landing the plane. A few minutes on the phone would work well. Trying though typed posts would be difficult. It's 7:40AM EDT USA . Send a PM or email with a phone number and I'll try to talk you down.

Two of these will go into a single bass reflex enclosure. The chip amp and Bluetooth adapter will be built into the project. The goal is a relatively compact unit to play better and louder than typical such portable devices. Actually, the goal is to have an excuse to buy a router and make some sawdust. More work in progress photos to follow.

I'll be combining the Lepai 20w x 2 T-Chip amp, and Logitech Bluetooth adapter (just to the right of the amp), 2 Radio Shack 40-1197 full-range drivers, 1 Parts Express knock-down MDF enclosure, as well as sundry other parts, to make a relatively small (albeit heavy) bass reflex portable unit to play music from any Bluetooth enabled phone. EDIT on 12/15/13: Due to the attachment data limits of the new forum, the attachments have been deleted for the posts. If interested, there are attachments at post #17.

This technique has been employed successfully several times. The driver pictured is a Radio Shack 40-1197 (Google it) given to me by this forum's Klipschguy. It arrived with the dented dustcap. I recommend this technique over drinking straws, pins & glue, replacing the dustcap, etc. Nothing else I tried worked as well.

With the use of this precision instrument, which some might recognize as an ancient Sears vacuum long ago relegated to garage only duty, problem solved.

We've all had this happen.

Search Cornscala. Cornwalls already have K55 drivers in the squawkers. The depth of the cabinet dictates a squawker horn with a 700hz cut-off. You seem to be asking if anyone has tried larger squawker horns, such as K400, with Cornwalls. If so, the answer is yes. Search Cornscala and you'll be kept busy for hours reading about the subject.

Dale- You did notice the reference to the h/k 730 in need of refurbishing. As soon as the SCA-35 is back the h/k 730 is headed your way. I'm eager to get your reaction to the Lepai's sound and contents. It's a better bargain from Amazon, especially if you're eligible for free shipping.

The modified La Scalas I did for the local high school band director are powered by a vintage h/k 730 receiver (35 watts/channel when new). It can produce more clean volume in a large space than humans should be asked to endure. When I first tested them, it was apparent they were ever so slightly less efficient, but I drove them to "call the police" levels with an antique Dynaco SCA-35 tube integrated amp that puts out a mere 17 watts/channel . . . on a good day. If you use the search function you'll find many threads detailing various versions of this mod. You'll notice a common occurrence. Almost exclusively, those critical haven't tried it; those favorable have done it. It's not for everyone, but it's quick, inexpensive and easily reversible.

Yes and yes. [y] I did it by enclosing the backs and modifying the networks per the collective advice of djk and BEC. The networks were temporarily outside the boxes until dialed in.

Charged capacitors don't need no stinkin' plug in the wall to deliver a lethal shock.

As shown in the photo, I powered all four single driver BR speakers with two 8 ohm speakers in parallel on each channel for a nominal 4 ohm load. The tendency to stridency in the high frequencies seemed to disappear. The results are consistent with Dean's comments. The reviews for this amp on the Parts Express site are extremely favorable. On the basis of value, it's hard to fault this little amp.
