I don't think they look ugly at all. The attractive truncated flange could be made to blend seamlessly into two huge 2.5" radius roundovers on a narrow 3 inch wide baffle board. If done right, you could make your speaker look like Chumley.
The 3" was about $100 when it came on the market, and the 4" was north of there. I would guess about $150.
That said- these are really long throw for their size, neo-slug underhung motors, the sliced heat-sink-phaseplug, etc. About the only improvement TB could do is give them the dimpled surrounds.
They have always been more than what I wanted to pay for them, but have always interested me.
Meh... just another marketing BS "Sales" flier with most items at regular prices and only a few decent things that are actually on sale. The only one that caught my eye is the little TDA7492 amp board that I've used a few times. Great sounding little amp board that is very happy being powered by a typical 19.3 Vdc, 3.xx Amp laptop brick. I bought a few in the past at $13, but I guess the current sale price isn't too bad.
Todays PE deal is a good one. The 830656 midbasses are very nice. My Indy 20/20 project used them. I've also built a small sealed 2 way with them and the DA25BG08-06. Geoff Millar gave my xo design a try and liked them too.
Their midrange is quite superior to the TCP115 drivers. Their biggest downside is they really need a larger enclosure for bass reflex, like 12-20 Liters. That's way too big looking for a bookshelf monitor with a 5.25" IMO, but a tall skinny tower would look/work good. Maybe even an MTM tower.
I used the 830656 in my 5th place 2012 Iron Driver entry. It was the iron driver that year and my speaker was the original C-note. They were going for $19.14 in 2012. I believe Geoff built a pair.
I built this MT with them and the XT25TG. They are part of the (hollow) stands they are sitting on so the total enclosure volume is 17 Liters. Their modelled F3 is around 34 Hz.
Honestly the PA165 looks more attractive to me, but the MB620 has power handling going for it, for those that need to blast 200W of midrange...not for home use I suppose. These MB drivers have no motor venting whatsoever, so air compression under the dust cap is definitely there, I can only assume the cause of the problem fairly low in frequency at 300Hz. It's about as basic as you can get for driver construction.

It's the roll-off, mild break-up and sensitivity that is most attractive to me.
I don't think I would drive them hard enough to be concerned with venting but your comments are well considered.

Curious DOTD today: Tang Band W4-1879 4" Full-Range Driver, marked down to $233.73 from $274.98. Holy inflation Batman!!
I don't recall the initial price of those, they're CAD$252 at Solen, so I guess the DOTD is a sweet deal..

Always wanted to try a pair of those...

Thanks for the heads up. Now I have to learn how to use this.

PE sale started today.
Toe in?

Love the SDS drivers for a solid budget build. I used the Peerless 830657 6.5" woofers, 6 each side in series - paralllel and they sounded incredible. For the 5 1/4 inch driver, the towers could be a lot smaller.

I noticed that almost all iron core inductors are back ordered at Meniscus and PE. Could not find one at Madisound as well. What's that about?
Mark told me that they can't get the cores.
Shopping for options. Many are cost prohibitive.
DSP/amps are in our future if we can get the boards . . .
The PE website still sucks. Been awhile since I whined about that.
Remember when they invited web site feedback? Did not go well, or last long!
Yeah, not enough reach around for old douchebag Stahl, I guess.

I like the 6.5 inch

It's strange that they claim 94dB sensitivity, when the graph pretty much shows about 90dB
