Custom 150W T-line powered subwoofer

This is a one off transmission line subwoofer enclosure for two 6.5 inch subwoofers and a 150 watt RCA plate amp. It's made from 3/4" MDF, just like a sub box for a car. Most enclosures sold in stores are built using particle board. I wanted it to stand out and not look like a car audio box. Its been paneled in 3/4in pine, and it looks beautiful. Sanded down to 220 grit, edges rounded and stained a beautiful dark tone. The box with subs/amp weighs at least 50lbs. Alot of material went into this, and it was well worth it. This subwoofer is comparable to something that puts out 250-300 watts thanks to the transmission line. Its an SQL or sound quality focused design. Very wide response range going as low as 31-32hz and I haven't found its peak yet.This subwoofer will make any genre of music sound great and you will hear notes that a normal enclosure sold at a store isn't capable of playing. As for long term reliability the amplifier doesn't get hot, and I bought the donor sub from an 80 year old man who bought it brand new, and used it for the system he had in his bedroom. The subs are both from units that were made in the 2010s. They have rubber surrounds not foam, and they don't come closen to bottoming out even on full volume. Although trust me, you won't need to crank this sub that loud barely ever, I keep it around 10% volume when I listen to music during the day. At 25% volume it's starting to rattle door knobs and light fixtures. At max volume this sub shakes things off my shelves and tables. Don't let the sound quality focused design fool you. I've owned many subs over the years and this thing is comparable to a 250-300 watt 10 or 12 inch sub. The inside has been stuffed and sealed using a bead of silicone. top and bottom were glued and screwed, the sides and baffles were first glued and stapled using an air nailer, and then screwed for extra strength. The amplifier is in a sealed compartment separate from the rest of the box to keep it from interfering with the integrity of the transmission line. The volume adjustment dial is located on the back right side. i couldn't put it anywhere else, it had to remain within the sealed compartment. It's held in place using hot glue on both sides and a piece of wood underneath for strength. it's been installed so it sticks out about 3/4" from the box side through a hole drilled through the top board. You will love this sub. You'll love looking at it and it'll give you an amazing listening experience can only be built!Something that looks this nice made from real pine, thick MDF, hand built locally with performance and sound quality on this level just cannot be bought in stores. In reality if you went to the one custom shop in town and had this built, you would be looking at about $650-$750 wrapped in felt like car sub. Im in the process of building a 10" 200w RMS pioneer 4ohm car sub with a 200 watt 4ohm advent plate amplifier right now that will be done in this style as well. If you want something with a bigger single driver I have that coming soon! I want $200 and I'm firm on that, I like this thing enough to keep if it doesn't sell.
