2008 Triumph Tiger - Black

Kind of been a wave function the last 15 years: Ducati, Triumph, Ducati, Triumph.

I just got a 2012 street triple r. Gotta love the fuel injection noise. I tell everyone that it is the supercharger lol!

Re: Fastbike1's OS MTM's

Haha it even says 4 Ohm (NORMAL) and 8 Ohm (HIGH)...

Re: Fastbike1's OS MTM's

There is no significant impedance difference between the OSMTM and the Swope MTM. In fact, the OSMTM might be a little lower.
The impedance sweeps for both are on Paul's web page.

I have a NAD 712 that will power the speakers (NOT the sub) and it has a 8/4 ohm switch in the back. Should be ready to play those???

Re: Fastbike1's OS MTM's

I am actually in the process of building a "modified" Swope sub as well. I got a great deal on a Dayton 500 watt amp and the SP10 on eBay, so off I went.

I am building the box 21.5"x12.5"x16" (with 1.5" front and back baffles), and using an upside down "U" style 3" port to make it fit (and just barely) in the box. It will be slightly larger than Paul C.'s original (45 vs 40 liters), with the port being about 0.5-1-inch longer which tunes it about 21Hz but since I got the larger Amp and has an EQ I am planning/modeled for a slightly more adjustment of 2-2.5db at 24 Hz and the model doesn't show any issues with my changes. The real test will be the first listening session.

It should get to 16-17Hz for an f6, tuned to 21 Hz and best of all at 500 watts runs out of xMax at 108db.

Are you doing yours as per Paul's plans, or modding yours? What kind of finish are you looking at, because I am torn between piano-gloss (color, not black) or a nice veneer?

Sounds interesting! I am doing a modified Swope sub as well, because the SP10 isn't availabe in Sweden and very expensive to get shipped here. Considering a Dayton driver, but this is a little OT in this thread. I started a thread HERE talking about my questions.

There is one thing that you should consider when comparing the OSMTM with the Swope MTM and that is the impedance of the speaker. The OSMTM is a "6-ohm safe" speaker according to Paul but the Swope MTM is a 4-ohm speaker and will need a much beefier amp. If you are looking at running the Swope MTM off of a consumer grade receiver you might want to make sure you won't burn it up with the Swope. I've looked at doing both and the I always come back to the added cost of a higher grade amp for the Swope speakers.

Thanks for answering in a thread that's been dead for 4 years...

It's a tough choice since the price difference is quite small. The reason to build the OSMTMs would be having such small speakers performing so well. The reason to build the Swopes is obvious. I'm building the Swope sub.

Re: Fastbike1's OS MTM's

My opinion... you can't go wrong with the MTM's, they do go quite loud (I run them with a 80W Onkyo HT receiver, nothing special) and they have filled the room to everyone's enjoyment for 4-6 large parties (20-30 people).
While I haven't built them (yet) the Swope's would probably be similar sound, but with a 5" you would probably get a little bit more all the way around.
Good luck, you certainly are considering some very nice designs and I think you would be very happy with either one.

Re: Fastbike1's OS MTM's

I built the OS TM and MTM's and the MTM's certainly can produce a much louder sound, but they do need to cross to a sub if you are going to be in the 100db range. You may even need to cross at 100 Hz (I have the TM's at 90, the MTM at 75 Hz), depending on the slope. I have the TM and MTM as my LCR currently in my home theater. It is only 400 square feet, but opens to another 500 square foot kitchen and a 250 square foot dining room. Also has 10 foot ceilings, so pretty large area.

Re: Fastbike1's OS MTM's

Just a couple of pics.

If you're thinking about building a set, DO IT. You won't be disappointed.

Jumping in on an old thread here, I know. But I am thinking of building the OSMTM or maybe the Swope MTM (if I can afford).
But my question is: will these fill my living room 43 sq mt (470 sq ft) to more than moderate listening levels crossed with a good sub? My thought is to actively XO at maybe 80 Hz to take some bottom end load off.

Re: Fastbike1's OS MTM's

YES! I was certain I was looking at a Triumph but couldn't determine model.

I ride a Vintage Bonneville, John Stockman is also a fan of Brit and European bikes.

Back to speakers.

Re: Fastbike1's OS MTM's

While mine weren't embarassed to be heard w/ the Vienna's, they would be like Cinderella before the ball next to your build.

Nice. I can't wait to get mine done.
