Side question, knowing I'm trying out those BIC mf-ers.

I have an L-shaped basement and am going to build a wall to portion off a 12'x14' section for the home theater. Should I try and get it as air tight as possible (without risking suffocating myself of course), or intentionally add in passive vents? Will it make any difference for acoustics?

I'm going to be adding in Roxul for sound proofing.

Well if you add vents it won’t be very sound proof :P

I’d seal it up, you don’t want bass leaking.

Leave it at 8 ohms and call it a day :)

When I visualize bass leaking, I think of Slimer from Ghostbusters leaving goo everywhere.

Exactly, we don’t want none of that!

Buy them at Home Depot of all places; free returns.

I mean, you know they're good if the Depot sells 'em right?

This AVS member loves them though...but I believe he's moved on IIRC.

Well, I’ve now tried twice to have a pair of those BIC 15s delivered. The first was from amazon, and when they arrived the boxes were missing chunks and looked like they had been deployed to a war with scuffs on the cabinets. Didn’t even bother unboxing, just sent them back.

The second set I ordered ship to store with Home Depot. I’m in Minnesota, the speakers shipped from Missouri. After 5 days and still no notification they made it to my local store, I pulled up the tracking info... the speakers spent a week being shuffled between Oklahoma, Missouri, and Georgia. The last update was they were returned to sender, so that order got cancelled too.

Mind you, these speakers weigh 75lb EACH. I’m guessing whomever has to deal with transferring them within UPS hates them.

Er, that sounds rather auto-erotic, let's move on...when you wall it off, will there be HVAC going in? Will this false wall be the rear wall?

I'd try to build it with offset-stud construction and mass loaded insulation threaded through, to reduce sound transmission. Then a shell of depleted uranium for added mass. You can get that from my new company, SKU #NU-KU-LER , just email [email protected]+11.com

Oh sweet, I need to replace my Uranium domes on my Soviet Audio bookshelves. Thanks!

Klipschorn bass horn analysis at northreadingeng.com

Of course with the Klipschorn, like many speakers, you have to specify which version with the same name that you're talking about...

Attached is an anechoic FR of the bass section. Klipsch has been adding 4dB to their anechoic for room gain since they first built their chamber, before that they actually measured in-room.

So, I finally got a pair of those BICs delivered in good shape (it actually took ordering 3 to end with 2 good ones, but the retailer on Amazon was good about getting a return authorized).

Compared to my Polk S60 towers and RTS12" powered sub, I would describe the BICs as:

80% fidelity
95% bass
110% loudness
25% cost

Dollar for dollar, if you just want decent quality, loud, and thumping audio, the BICs are a darn good value.

Awesome man, glad you are enjoying them.

And those Polk S60’s aren’t slouches either so for them to be 80% fidelity is really good.
