LECBOS Buyout MTM $120/pair

[LouC]

I've finished up the LECBOS build (includes a BOM). Added some text and new pictures to my webpage: LECBOS

July 5 - I bumped the padding resistor for on wall mounting. Added some pictures of the final setup, and a bit more to the write-up.

Can't wait to see and hear 'em in person!:D

Ah yes! Another cool build form Lou. I have a set of those tweeters to use up too.

Re: LECBOS Buyout MTM $120/pair

I remember someone comparing these favorably to a lot of commercial designs at $300 or more a pair. Considering that these use Peerless' cheapest woofers and what is, to be honest, a less-than-awe-insipring (albeit affordable) tweeter, you must have done one heck of a crossover.

You never get something for nothing. Like I said in the write up, not going to win any bass competition, but what's there is exceptionally good for the price.

Re: LECBOS Buyout MTM $120/pair

They look pretty sweet. I had a real internal struggle over buying the Peerless woofers, especially at the price! But ultimately my desire to stick to "still-being-produced" kept me from purchasing them. Anyway, I already have several buyouts that I need to work with before I purchase more.

Only issue, why cover up beautiful birch?

The birch used on handi-panels is often pretty plain. Sometimes we want more character and grain on our cabs.

Around here, 1/2" baltic is about the same as a sheet of 3/4 MDF. It took me about three hours to cut & bang out those cabinets with brad nailer. About 10 minutes to finish them with a sponge roller. Aesthetics are not a big concern for my workshop wall. Especially when it's 110 degrees. :eek:

Now find me some kid who enjoys sanding, filling, spraying for $10/hour and we're on. :D

Rogoll: Buy an extra driver on the buyouts. At $10, you've got a backup.

Just heard these again, this time in their final resting place: mounted on the shop wall. They're also now mated with one of Mr. Fitzmaurice's subs. Sounds great. Every shop should be so lucky.

The quality of baltic out here has gone down considerably. Lots of "footballs" on both sides. You have to sort through the piles to find a clean side.

hehe Yeah I've got 4 of the woofers stashed away for another lambics build although the LECBOS would be very tempting for my garage.... (ponders how wife would take having the next project start up so soon...)

LouC:

I saw the baffle dimensions on your site, but was wondering if you would mind providing the internal dimensions of your cabinets. Question, would the internal dimensions you used work correctly with the tube port you mention on your site?

Thank you,
Leonard

Re: LECBOS Buyout MTM $120/pair

Lou gives the net volume and the external dimensions. Says the tube port is equivalent. What else do you need? If you have trouble visualizing the box, search for Boxycad2. Works well for prism boxes. Lou was careful to specify net volume, so don't forget to account for braces and drivers. Boxycad can reasonable account for bracing.

Re: LECBOS Buyout MTM $120/pair

Since everything is +/-10%, you can probably build from 18.5-22 liters without appreciable difference in bass reproduction and minor changes in port length.
I suggested 4.5" Length for 18.5 liters, 3.25" for 22 liters (the PE Cabinets). Volume of drivers & crossover is negligible. My tuning is designed to sacrifice a few hertz on the bottom end for a bit better excursion control.

Re: LECBOS Buyout MTM $120/pair

Hey Lou,

This looks like a great design to get my feet wet. I had asked in an earlier post about a "budget" design, and this sure seems to fit the bill. (I was directed to your site about the Cyclops and asked about your center as well.)

If you would please excuse my ignorance, what would be involved in decreasing the width to 8". Would the port need to change? You say +/-10% on dimensions, so i am guessing, with my old ears, nothing.

I don't know how to post the original link to my post, but I am limited to 8" max for my center.

Also, this would be set to small on my receiver. Is there any benefit to making them sealed? or would that require a whole remake of the design.

I thank you in advance.
