This project you posted looks awesome. I hope OP takes advantage of it with a few pictures and final observations.

Thank you Inductor . If someone move the simulation into Sketchup or a Cad: program,the unclear ? dimensioning of the Port system would be much more clearer....

Here are more on the same subject: A lot more numbers to dig into

Default DOH...

I learn so much from your posts.
Things like several mistakes and bad assumptions that I made in building the first Lab 12 OD_ML_TL.
I was wondering why the stuffing material was so hard to fluff up enough to fill almost the entire line, and
I have finally come to fully understand port end effect corrections, and it is not the same as when modelling intakes on 2 stroke engines as I was thinking it may be.

Thank you,

Thank you for the help, the project is underway! I will post with results and pics.

Now I need to find a new receiver...

Sound quality for music is my most important requirement with easy calibration and room correction. Good Home theatre audio quality is a bonus but I am willing to separate HT entirely or sacrifice this for best music sound.

I mostly listen to rock (elvis - classic - punk - metal - alt/indy rock) and ALL types of electronic.

First a few things I would like:
- I dont want a receiver that will colour or brighten sound, natural the way the music was recorded would be ideal.
- Very good EQ to balance and correct sound within a room as needed easily.
- Cool running.
- With HT I want to make sure that I dont have to crank volume to hear voices in movies and then sounds effects are too loud (current old low end sony sucks for this). Also HT should have THX.
- Best Value for the $, my budget is $600.
- 4ohm stability. My subwoofer is two ID 10" 4ohm subs in custom box with 300watt bash plate amp so this would not require 4ohm stability. I have nice car audio ID CSX64 co ac speakers that I would like to build boxes for home. I would like to be able to use high end home audio speakers at 8 ohm in the future as money allows.

I am currently looking at the Onkyo 709, is this the best option in my budget?
Any suggestions on good receivers, and where to buy, would be appreciated.

No not really, home audio is all new to me so I am looking for some suggestions. As mentioned my previous experience is onlu with an IASCA winning sound quality vehicle.

I was thinking of using the 709 for now, my sub has a plate amp, and adding amps for other speakers using the pre outs as I get the $. Unless there are better suggestions. Any assistance is appreciated as I only wish to buy each poece once for a long time.
