Looking for 2 full range speaker recommendations

Looking for 2 Shielded full range speaker recommendations

Hi all,

I started to do a desktop build a while back but had to postpone due to life interrupting. Anyhow I'm back and ready to do a desktop build similar to the link below. I really need a 4 inch shielded full range speaker recommendation for the amps below. Price wise for the Lp-2020a I'd like the speakers to be around 20 to 30. The Qinpu - A-6000 MKI is another amp I'm looking at down the road for and upgrade. I'd also appreciate a 4" speaker recommendation for it with a price range around $80.00 each.

Thanks for your reply. Those speakers have came up on my searches and I have the Tang Band saved as one of my favorites. Do they make shielded versions of these speakers? They will be used on my pc desk and I always have items that aren't magnet friendly on my desktop charging or docking. You know, cell phones, tablets, HDD etc.
 
How do you feel about the Tang Bands W4-1337D? Shielded, full-range, what's not to love? From what I'm reading the MA Alp 7.3 would need a larger inclosure than what I'm going to be building.

Chris, both amps are not the best choice, the Lepai is fun for a short while then you realize how distorted it sounds - it is a cheap build - nothing for serious listening - perhaps for backyard...:) The very best champ on the block is the Dayton DTA 100a for mere $80.00 or so. U simply cannot do better than that. They have some quality issues but if get lucky it's the best $80.00 you will ever spend.
4" drivers - TB is a good choice as the sound is natural out of the box, other drivers will take lot of time to tune. But if this is for a desktop I would consider 3" TB drivers as there is simply no contest in resolution and fidelity - the 4" drivers sound already congested if not implemented properly.
 
I built these computer speaks with Tang Band W4-1320SJ. 4 inch PVC T and end cap. About 3.5 liters tuned to 80 Hz.

It's a neo motor, but it is enclosed with steel. Don't know how shielded it is, but it sounds real good. Near field, about 18 inches from my head.
 
For now I've ordered 3" Tang Band drivers and a Lepai amp. I really wanted to go with Mark Audio but I wasn't able to find a speaker that would work for my application, shielded 3" to 4" that will be great for a small enclosure.

Jerry, Thank you for your post. It lead me to about 3 hours of reading. I really like the look of the DTA100a and the reviews are great. As you point out, I'm a little worried about the reliability. However after reading bout it and class T amps, it lead me to the topping TP30 amp. It's only 15w but has an on-board sound card. For my application, on my computer desktop, I think it'll fit my application best.

Talk about industrial chic. I really like your setup Mike. I need to find out about parts expresses return policy and try 4" and 3" to find what works best.
 
Thanks. The inside is lined with half inch sonic barrier foam from PE.

Working with these 4" PVC pipes is just as hard as wood. The glue grabs fast with that much area so you have to be quick.

The grills are 92 mm fan guards and the bases are solid marble discs. The port is mostly external too, so not much internal volume subtracted. I put them on little wall mount shelves, no desk space used either.
